Chapter 16: FHA Lending in Depth: HUD Handbook 4000.1, MIP, and the Borrower FHA Was Built For

"FHA is not a loan for people with bad credit. It is a loan for a file with a particular shape, and if you cannot describe that shape you will sell it to the wrong borrower twice a year for your whole career." — constructed; the way a good FHA underwriter explains it to a new loan officer

Overview

Two files sit on your desk this morning and both of them are FHA questions.

The first is Linden Street. Two W-2 borrowers, a 706 representative score, \$10,500.00 a month of qualifying income, \$38,000.00 in verified assets, buying at \$385,000. They asked, on day 1, whether they should be doing an FHA loan, because a coworker told one of them that FHA "only needs three and a half percent down." They are right about the three and a half percent. On day 2 you ran the comparison and the answer was no — and the reason it was no has nothing to do with the down payment.

The second is Harlow Street. One borrower, one income, a 641 representative score, \$4,150.00 a month, \$395.00 in monthly debts, buying a \$215,000 townhome with a county down-payment assistance second funding the entire minimum investment. The ratios come out at 41.48% front and 51.00% back. Under the manual-underwriting benchmark you have probably had recited to you — 31% and 43% — that file is dead on arrival. It is not dead. It is approvable, and this chapter explains exactly why, and exactly what has to be true for it to survive an underwriter.

Those two files are the whole chapter. FHA is the most misunderstood program in residential lending, in both directions. Loan officers sell it to borrowers who would be better off conventional, because the down payment is smaller and the conversation is easier. And loan officers decline borrowers FHA was designed for, because they memorized a ratio benchmark that is not a ceiling, or because they think 641 is a bad score, or because nobody ever walked them through what mortgage insurance premium actually costs over thirty years.

The most important thing in this chapter is a single structural rule about how long the annual premium lasts, and it is a rule that a great many working originators get wrong. It decides the Linden Street comparison. It is invisible on the Loan Estimate. And it is set once, at the closing table, by a number the borrower has complete control over that day and no control over ever again.

Everything here is illustrative. FHA's premium factors, its loan limits, its score thresholds, and its duration bands are all set by HUD and all of them have moved — some of them repeatedly, some of them within the last few years. Verify every current figure with HUD before you quote it to a human being. That instruction is not a disclaimer. It is the professional standard, and this chapter is the most exposed in the book to the cost of ignoring it.

In this chapter, you will learn to:

• Explain what FHA is, what it insures, and who actually lends the money
• Use HUD Handbook 4000.1 and its mortgagee letters as a working reference
• Apply the 31%/43% manual benchmark correctly — as a benchmark, not a cap
• Compute the minimum required investment and validate its source
• Calculate UFMIP and annual MIP, and determine the duration category from the LTV at origination
• Read an FHA appraisal for minimum property requirements as well as value
• Recognize the FHA-specific conditions that stop a file cold
• Run the FHA-versus-conventional comparison in total dollars and state who each program is for

Learning Paths

🎓 Exam — §16.5 and §16.3, in that order. The SAFE test asks about MIP versus PMI, about UFMIP being financeable, and about the 31/43 benchmark. Know that FHA insures and does not lend. 🏠 New LO — §16.4, §16.5, and §16.10. These are the three places a new originator costs a borrower real money by not knowing the rule. 🤝 Partner — §16.6 and §16.7. If you are a real estate agent, the FHA appraisal's property conditions and the 90-day resale restriction are the two things most likely to blow up your listing, and neither is the loan officer's fault or within their control. 📊 Operations — §16.7 and §16.9. Case-number hygiene and streamline eligibility are pure process, and both are cheap to get right and expensive to get wrong.

16.1 What FHA is and what it is not

Start with the sentence that fixes half the confusion in this chapter: the Federal Housing Administration does not lend money.

FHA is a mortgage insurance program. It was created by the National Housing Act of 1934, in the middle of a housing collapse in which the typical mortgage was a short-term balloon loan requiring a large down payment, and in which a homeowner who could not refinance at maturity lost the house. FHA's answer was to insure lenders against loss on long-term, self-amortizing, high-loan-to-value mortgages. Once the lender's downside was covered, the lender could offer terms that would have been reckless otherwise: small down payments, long amortization, and a fixed rate.

That is still exactly what it is. Ninety years later, the mechanics are unchanged in outline:

  And afterward: the closed loan is pooled into a GINNIE MAE security. Ginnie Mae
  guarantees timely payment to the investor; FHA insures the credit loss to the lender.
  Two different guarantees, two different beneficiaries. The exam likes this.

  LEGEND for every diagram in this chapter: boxes are parties or decisions,
  arrows are the direction money or authority travels, and nothing is to scale.

Read that diagram carefully, because it contains four facts that get confused constantly.

FHA insures the lender, not the borrower. The borrower pays the premium and the lender receives the protection. This is not a scandal — it is the same structure as private mortgage insurance on a conventional loan, and it is the reason the borrower gets a rate and a down payment that would otherwise be unavailable. But when a borrower says "I have mortgage insurance, so if I lose my job I'm covered," they are describing a product that does not exist here. Say so kindly and immediately.

The money comes from the same place all mortgage money comes from. Your employer funds it, usually on a warehouse line, and the closed loan is pooled into a Ginnie Mae security bought by an investor. FHA's role is to stand behind the credit loss. Chapter 1 traced this chain; FHA does not change it, it just inserts a government insurer at the credit-risk step.

The Mutual Mortgage Insurance Fund is a real balance sheet with a real capital position. Every premium a borrower pays goes into it and every claim a lender files comes out of it. When the fund's capital position deteriorates, premiums go up and terms get tighter; when it recovers, premiums come down. This is not abstract. The single most consequential rule in this chapter — the one in §16.5 — was adopted in 2013 in direct response to the fund's condition. Case study 1 tells that story.

The workhorse program is 203(b). When someone says "an FHA loan," they almost always mean Section 203(b), the basic single-family mortgage insurance program: an owner-occupied one-to-four unit property, fixed or adjustable, up to a county loan limit. FHA runs other programs — 203(k) for purchase-plus-rehabilitation, 234(c) for condominiums, and the Home Equity Conversion Mortgage for reverse mortgages, which Chapter 35 covers — but 203(b) is what your pipeline will be made of, and it is what this chapter means unless it says otherwise.

What FHA is not

It is not a loan for people with bad credit. This is the industry's most durable misconception, repeated by loan officers who should know better. FHA's underwriting is not lenient about credit history — it has waiting periods after bankruptcy and foreclosure, it requires explanation of derogatory accounts, and it will downgrade a file to manual underwriting for a recent mortgage delinquency. What FHA actually is, is insensitive to score in its pricing. That is a completely different thing, and understanding the difference is most of §16.10.

It is not a first-time-buyer program. There is no first-time-buyer requirement in 203(b). It is heavily used by first-time buyers because they are the population most likely to be short on down payment and reserves, but a borrower on their fourth house can use it.

It is not a low-income program. FHA has no income limits. USDA does; certain conventional affordable products do; some down-payment assistance programs do. FHA does not. Chapter 17 handles VA and USDA, and the distinction is worth carrying: FHA is defined by the file, not by the borrower's demographics.

It is not automatically cheaper. This is the one that costs borrowers money, and §16.10 proves it in dollars on the Linden Street file.

It is not free of loan limits. FHA publishes maximum loan amounts by county, with a national floor and a national ceiling both keyed to the conforming loan limit, and higher limits for two-, three-, and four-unit properties. Those limits change annually. Look them up for the specific county every single time, because a borrower two counties over from your office may have a limit tens of thousands of dollars different from the one you remember. Verify current limits with HUD.

One genuinely valuable FHA feature that almost nobody mentions on a purchase call: FHA loans are assumable, subject to the new borrower qualifying and the lender approving. In a rate environment where a seller holds a note two or three points below the market, an assumable loan is a real asset attached to the house. It is not a reason to choose FHA by itself. It is a reason to know it exists, and Chapter 37 returns to it.

📞 On the Phone

Borrower: "My coworker said we should do FHA because we don't have twenty percent down."

The lazy answer: "Sure, we can do FHA." You have just agreed to a structure you have not priced, on the recommendation of someone who does not work in this industry.

The answer that works: "Maybe — let me actually price it both ways and I'll show you tonight. Here's the short version so you know what I'm looking at. FHA lets you put down three and a half percent instead of five, so that's about fifty-eight hundred dollars less at the table. But FHA charges an upfront insurance premium that gets added to your loan, and on your numbers that premium is bigger than the money you saved. And the monthly insurance on an FHA loan at three and a half percent down doesn't ever come off — not at twenty percent equity, not at fifty. On a conventional loan it comes off automatically. So the question isn't which one is easier to close. It's which one is cheaper for you, and I have to run it to know."

What just happened: you did not sell a program, you named the trade-off, and you set a deadline you control. You have also pre-empted the conversation where they find out about life-of-loan MIP from a stranger on the internet in year four. Chapter 8 covers the expectation-setting version of this call; here the point is narrower — never agree to a program before you have priced it.

16.2 The handbook and how to use it

Conventional lending has the Fannie Mae Selling Guide and the Freddie Mac Seller/Servicer Guide, which Chapter 14 introduced. FHA has HUD Handbook 4000.1, the Single Family Housing Policy Handbook.

You should know three things about it: what it replaced, how it is organized, and — most importantly — why the handbook alone is not the answer.

What it replaced

Before 2015, FHA policy was scattered. A guideline question might be answered in a handbook from the 1990s, or in a mortgagee letter from 2009, or in a notice, or in a frequently-asked-questions document, and the four of them did not always agree. Underwriters carried folders. Handbook 4000.1 consolidated that mess into a single, searchable, free, public document covering the loan from lender approval through claims.

The practical consequence for you: there is now exactly one place to look, and you have no excuse for guessing. When an underwriter conditions your file for something you have never seen, the correct response is not to argue and not to capitulate. It is to open 4000.1, find the section, read it, and then either clear the condition or go back with the citation.

How it is organized

The handbook follows the life of the loan. In outline:

Nearly everything in this chapter lives in the second section. Inside it, the structure repeats in a distinctive and very usable pattern. For most topics the handbook gives you a definition, then a standard (the rule), then a required documentation block (what the file must contain to prove the rule was met). Once you learn to read in that rhythm you can answer most questions in ninety seconds.

There is a second organizing distinction inside that section that trips up more originators than any other: the rules for files underwritten through the TOTAL Mortgage Scorecard and the rules for files underwritten manually are in different places. They are not the same rules. A ratio limit you found in the manual-underwriting subsection does not govern a file with an Approve/Eligible, and a documentation reduction you found in the TOTAL subsection does not apply to a manual file. Section 16.3 is entirely about the damage that confusion causes.

Why the handbook is not the whole answer

Because HUD amends it by mortgagee letter.

A mortgagee letter is a numbered policy communication issued to FHA-approved lenders. It announces new policy, changes existing policy, or sets a premium schedule, and it takes effect on a stated date — very often keyed to the date the FHA case number was assigned, not the application date and not the closing date. Mortgagee letters are eventually incorporated into the handbook, but there is always a window in which the letter is the law and the handbook has not caught up.

This is not a technicality. Every significant FHA premium change of the last fifteen years arrived as a mortgagee letter with a case-number effective date. If you quote a premium from a handbook section that a letter has superseded, you have quoted a number that does not exist.

The working habit: check the handbook, then check the mortgagee letter page for anything issued since the handbook's revision date on that topic. It takes two minutes. Do it before you quote anything that involves a premium, a limit, a threshold, or a waiting period.

⚖️ Compliance Check

The sourcing standard for a guideline claim.

When you tell a borrower, an agent, or an underwriter what FHA requires, you are making a factual assertion that someone will rely on. Hold yourself to the same standard you would want an underwriter to hold themselves to:

• Cite the handbook section, not a memory. "4000.1 addresses this under gift funds" beats "I'm pretty sure gifts are fine."
• Check for a superseding mortgagee letter before quoting any number that has a dollar sign or a percent sign attached to it.
• Never quote a guideline from a blog, a forum, a rate-comparison site, or a training deck older than the last handbook revision. Secondary sources are for orientation. They are not authority, and this book is a secondary source too.
• Distinguish HUD policy from your lender's overlay. Chapter 14 defined overlays; they are everywhere in FHA, particularly on minimum credit score. "FHA allows it" and "we will do it" are two different sentences and you must be able to say which one you mean.

Requirements change, mortgagee letters are issued continuously, and state law adds its own layer on top of federal program rules. Verify current requirements with HUD, with your compliance department, and with your investor before you rely on anything in this chapter.

16.3 Credit and the manual-underwriting benchmarks

This section owns the number that gets misquoted more than any other figure in FHA lending.

The minimum decision credit score

FHA's term for the representative score is the minimum decision credit score. Chapter 10 defined how a representative score is derived; FHA applies the same lower-of-the-middles logic across borrowers, and the resulting number does two jobs.

The first job is eligibility: FHA's structure ties the score to the minimum required investment. The published structure has, for some years now, looked like this [illustrative structure — verify current thresholds with HUD]:

The second job is nothing. And that is the point most originators miss.

FHA's mortgage insurance premium is not priced off the credit score. A 640 borrower and a 760 borrower at the same loan-to-value pay the same annual MIP factor. On a conventional loan the difference between those two scores can more than triple the mortgage insurance factor, because private MI is risk-priced. This one structural fact — insensitivity to score in the premium — is what makes FHA the right answer for a whole category of borrower, and §16.10 quantifies it.

Note-rate pricing is a separate matter. FHA note rates are set in the Ginnie Mae market and are generally less score-sensitive than conventional rates, but your lender still has a rate sheet with adjustments on it, and your lender's overlay may refuse a score FHA would accept. Most lenders do not originate at 580. Many stop at 600, 620, or 640. Find out where your shop stops before you quote a borrower in the 500s, because "FHA allows it" is not an approval.

Manual underwriting and what triggers it

Chapter 15 covered the TOTAL Mortgage Scorecard and what a findings report says. The FHA-specific consequence is simple to state: a file either has a TOTAL approval or it is underwritten manually, and the two paths have different rules.

Manual underwriting is required when TOTAL returns a Refer, and it is also required when a downgrade is triggered — that is, when the underwriter must set aside an Accept because something in the file is not in the data the scorecard evaluated. The recurring downgrade triggers include a mortgage payment delinquency inside the last twelve months, disputed derogatory accounts above a threshold, undisclosed debt discovered after the fact, a borrower with no usable credit score, and — the catch-all — any information in the file that the underwriter concludes makes the Accept unreliable. [Illustrative list; the enumerated triggers are in 4000.1 and change. Verify.]

That last one deserves emphasis. An underwriter can downgrade a file to manual for a reason the scorecard never saw. If you have been treating an Approve/Eligible as the end of the credit conversation, this is the FHA-specific reason to stop.

The 31%/43% benchmark, stated correctly

Under manual underwriting, FHA publishes a table of qualifying ratio limits. The base cell of that table is a 31% housing ratio and a 43% total debt-to-income ratio, and the table permits higher ratios as documented compensating factors are added, with the permitted maximums keyed to the minimum decision credit score. The specific cells and the enumerated list of acceptable compensating factors are published in 4000.1 and have been revised. Look up the current table. Do not work from memory — including mine.

Here is what matters more than the cells:

31/43 is a benchmark for manually underwritten files. It is not a cap on FHA approvals.

A file with an Approve/Eligible from TOTAL is not governed by that table at all. The scorecard has evaluated the ratios along with everything else in the file and issued a recommendation; the ratio limits in the manual-underwriting subsection do not apply to it. This is not a loophole and it is not a lender's interpretation. It is how the two paths are structured, and it is stated plainly in the handbook.

The reason this matters is that a loan officer who has memorized "43" declines borrowers who are approvable. Which brings us to Harlow Street.

📄 Read the File

text FIGURE 16.1 — "Fifty-one percent, and approvable" [the Harlow Street file] THE DOCUMENT FHA Loan Underwriting and Transmittal Summary (HUD-92900-LT), the FHA counterpart to the conventional 1008, prepared at submission. Read alongside the TOTAL findings it summarizes. THE CONTEXT A single borrower, one income, buying a $215,000 townhome. FHA 203(b) with a $10,000 forgivable county second funding the entire minimum required investment. Gross monthly income $4,150.00. Other monthly debts $395.00. Minimum decision credit score 641. WHAT IT SHOWS Sales price $215,000. Adjusted value $215,000. MRI 3.5% = $7,525.00, funded by the DPA second. Base loan $207,475.00 -> LTV 96.50%. UFMIP 1.75% = $3,630.81, financed. Total loan $211,105.81. Note rate 6.250%, 30-year fixed. P&I $1,299.81. Annual MIP at a 0.55% factor = $96.76/month. Taxes $215.00. Hazard insurance $110.00. PITI + MIP = $1,721.57. Ratios: housing 41.48% ($1,721.57 / $4,150.00); total debt 51.00% ($2,116.57 / $4,150.00). CLTV 101.15% (($207,475 + $10,000) / $215,000). Underwriting method: TOTAL. Recommendation: APPROVE/ELIGIBLE. WHAT IT DOESN'T It does not show whether this borrower can live at 51.00%. A ratio is a gross-income calculation and knows nothing about withholding, health premiums, childcare, or the fact that a townhome has an assessment that can be raised by a board. It does not show the DPA program's own eligibility conditions, which are a separate approval on a separate calendar (Chapter 33). It does not show what happens if this borrower sells in year three, when the second is only 60% forgiven. THE DECISION Submit it, and submit it with the compensating factors documented in the file rather than asserted in a cover letter — verified reserves, the payment-shock comparison against current rent, and any additional income that was not used to qualify. Then tell the borrower, in one sentence and out loud, that fifty-one cents of every pre-tax dollar is committed before groceries, and ask them whether that is a life they want. That conversation is not optional and it is not a formality. THE LESSON The 31/43 benchmark governs MANUAL underwriting. This file has an Approve/Eligible and is therefore not measured against it. An originator who declines this borrower on the strength of a remembered "43" has cost a household a house and cost themselves a closing, and has done it by applying a real rule to the wrong path.

Constructed teaching file. Premium factors, rate, and ratio limits are illustrative; verify current figures with HUD.

Two footnotes on that figure, because they matter.

First, the arithmetic. \$1,299.81 + \$96.76 + \$215.00 + \$110.00 = \$1,721.57. Divided by \$4,150.00 that is 41.48%. Add the \$395.00 of other debt and \$2,116.57 ÷ \$4,150.00 = 51.00%. Every figure in that block resolves, and you should verify a submission's ratios by hand at least until the day you stop finding errors in them.

Second, "approvable" is not "should." An Approve/Eligible tells you the file meets the investor's requirements. It does not tell you the borrower can afford the house. This book's recurring argument about debt-to-income applies with full force here: 51.00% will approve, and 51.00% is a great deal of a modest income. The loan officer's obligation is to make sure the borrower understands the number they are signing, in dollars and not in percentages, before they sign it.

16.4 The minimum required investment and acceptable sources

FHA does not use the phrase "down payment" in its rules. It uses minimum required investment (MRI) — the borrower's own required contribution to the transaction, computed as a percentage of the adjusted value, which is the lesser of the purchase price or the appraised value.

That definitional detail matters exactly the way it matters on a conventional loan and for exactly the same reason: if the appraisal comes in low, the MRI is computed on the lower number, and the borrower's cash requirement goes up rather than down. Chapter 18 works the appraisal generally and the Cypress Court file shows what a short appraisal does to a structure; the FHA wrinkle is only that FHA computes on adjusted value by name.

On Linden Street:

$$\$385{,}000 \times 0.035 = \$13{,}475.00$$

On Harlow Street:

$$\$215{,}000 \times 0.035 = \$7{,}525.00$$

Both assume a minimum decision credit score of 580 or above. Below that, the illustrative structure in §16.3 raises the MRI to 10%.

Where the money may come from

This is where FHA is genuinely more permissive than conventional lending, and it is also where files get killed. Chapter 12 covered asset documentation and sourcing generally. The FHA-specific question is not "is it documented" but "who does this money ultimately belong to, and do they have an interest in this sale?"

Broadly acceptable sources include the borrower's own verified funds; a gift from a relative, an employer, a labor union, a close friend with a clearly defined and documented interest in the borrower, a charitable organization, or a governmental entity or public agency operating a homeownership program; and down-payment assistance from an eligible governmental entity or an instrumentality of government. Documentation requirements are specific — a gift letter, evidence of the donor's ability to give, and a traceable transfer are the baseline — and 4000.1 states them precisely. [Illustrative summary; verify the current acceptable-source list and documentation requirements with HUD.]

Broadly unacceptable is anything that traces back to a party with an interest in the sale: the seller, the real estate broker or agent, the builder, or any entity funded by them for this purpose. FHA's language for these is interested parties, and the prohibition covers indirect routes as well as direct ones.

That last clause has a history, and it is the subject of case study 2. For roughly a decade, a structure existed in which a seller made a "donation" to a nonprofit, the nonprofit made a "gift" to the buyer, and the gift funded the buyer's MRI. The loans performed materially worse than comparable FHA loans, and Congress prohibited seller-funded down-payment assistance for FHA loans in the Housing and Economic Recovery Act of 2008, effective October 1, 2008. The rule that survives is the general one: a seller may not fund the borrower's minimum required investment, directly or indirectly.

Interested-party contributions: what the seller may do

A seller may still help — with closing costs, prepaid items, and discount points, up to a published percentage of the sales price. FHA's permitted contribution has long been more generous than the conventional tiers Chapter 14 described; treat any specific percentage as [illustrative — verify the current limit with HUD].

The Linden Street contract carries a \$3,000 seller credit toward closing costs, which is 0.78% of the \$385,000 price. It is nowhere near any limit under either program, which is the common case. The limit becomes real on files where a seller is buying down a rate or covering a large prepaid escrow deposit, and the failure mode is arithmetic rather than dramatic: the credit exceeds the cap, the excess must be removed or reduced, and the borrower has to produce cash they budgeted for something else, three days before closing.

⚠️ Where Deals Die

The MRI that came from an interested party by a route nobody drew on a napkin.

This is not usually fraud. It is usually a well-meaning arrangement that nobody thought to disclose, and it surfaces in underwriting as an unexplained deposit or a wire from the wrong account. Real examples of the shape:

• The seller is the borrower's employer and the "employer gift" is really a price concession.
• The buyer's agent offers to "rebate part of my commission to help with the down payment."
• The builder offers a "closing cost credit" that is quietly sized to cover the MRI.
• A family member's gift is actually a loan, with a signed side agreement the file never sees.

What it costs: at best, a restructure and a delay while the funds are replaced from an acceptable source. At worst, the loan is not insurable, which means it is not saleable, which means it does not close — and a borrower who has been packing boxes for three weeks does not get the house.

What the disciplined originator does: ask the source question at application, in plain language, and ask it about every dollar. "Where is the down payment coming from? Is any part of it coming from the seller, the agent, the builder, or anyone connected to the sale? Is anyone expecting to be paid back?" Ask it once, early, and write the answer down. Then, when a \$4,900 deposit shows up on day 33 the way it did on Linden Street, you already know whether you are sourcing an ordinary commission check or unwinding a problem.

And note the asymmetry that makes this genuinely dangerous: the borrower usually does not know the arrangement is a problem. Nobody is hiding anything. They are being helped by people who like them. Your job is to know the rule and to ask before the money moves, not after.

16.5 UFMIP, annual MIP, and duration

This is the load-bearing section of the chapter. If you take one thing from Chapter 16, take this.

FHA charges two mortgage insurance premiums, and they are different animals.

Upfront mortgage insurance premium (UFMIP)

The upfront mortgage insurance premium is a one-time charge assessed as a percentage of the base loan amount at closing. It has been 1.75% for some years now [illustrative — verify the current UFMIP percentage with HUD]. It may be paid in cash or, far more commonly, financed — added to the base loan amount, so the borrower pays interest on it for thirty years.

On Linden Street as an FHA file:

$$\$371{,}525.00 \times 0.0175 = \$6{,}501.69$$

That figure is added to the base loan: \$371,525.00 + \$6,501.69 = \$378,026.69. Note what happens to the loan-to-value calculation, because this is a reliable exam question and a reliable source of confusion on a rate sheet: LTV for FHA program purposes is computed on the base loan amount, before the financed UFMIP.

$$\text{LTV} = \frac{\$371{,}525.00}{\$385{,}000} = 96.50\%$$

not \$378,026.69 ÷ \$385,000, which would be 98.19%. The financed UFMIP does not push the borrower into a different LTV band. Remember which number does what: the base loan sets the LTV; the total loan sets the payment.

Now do the arithmetic the borrower actually cares about. The FHA structure saves them \$19,250.00 − \$13,475.00 = \$5,775.00 in cash at the table. The financed UFMIP adds \$6,501.69** to what they owe. The premium is **\$726.69 larger than the cash it saved, and they will pay interest on it for three hundred and sixty months.

That does not make FHA wrong. It makes "FHA needs less money down" an incomplete sentence, and you should never say it without the second half.

Annual MIP

The annual MIP is the ongoing premium, expressed as an annual percentage and collected in twelve monthly installments with the payment. Its factor depends on the loan amount, the loan term, and the loan-to-value at origination — not on the credit score. This book uses 0.55% [illustrative — verify current annual MIP factors with HUD].

On the Linden Street FHA structure the factor is applied to the total loan amount:

$$\$378{,}026.69 \times 0.0055 = \$2{,}079.15 \text{ per year} \;\rightarrow\; \$173.26 \text{ per month}$$

On Harlow Street: \$211,105.81 × 0.0055 = \$1,161.08 per year → \$96.76 per month.

In practice the annual premium is recalculated each year against the outstanding balance, so the monthly installment drifts down slowly over the life of the loan. This chapter holds it constant for comparability, which slightly overstates the later years. It does not change any conclusion here by enough to matter, and it makes every figure checkable by hand.

Duration — the rule that decides everything

Here is the part that matters most, and the part working originators most often get wrong.

How long you pay annual MIP is determined by the loan-to-value at origination, and the category is set once at closing and never revisited.

For terms greater than fifteen years, the structure is [illustrative — verify the current duration bands with HUD]:

Read that table twice. Then read the consequence:

A borrower who puts 3.5% down can never reach the eleven-year band. Not by paying extra principal. Not by the house appreciating. Not by requesting a new appraisal in year seven showing 55% loan-to-value. The category was decided by the down payment at the closing table, and nothing that happens afterward reopens it.

  ────────────────────────────────────────────────────────────────────────────────
  LINDEN STREET AS FHA:  base $371,525 / $385,000 = 96.50%  →  LIFE OF THE LOAN

  A 3.5% minimum required investment produces a 96.50% LTV. There is no version
  of a 3.5%-down FHA purchase that lands in the 11-year band. The band is chosen
  by the size of the down payment, at the table, one time.
  ────────────────────────────────────────────────────────────────────────────────
  THE ONLY EXITS:  pay the loan off, sell, or REFINANCE OUT OF FHA.
  Note that an FHA streamline (§16.9) is usually NOT an exit, because it uses the
  ORIGINAL appraised value and therefore usually reproduces the original LTV band.
  ────────────────────────────────────────────────────────────────────────────────
  Terms of 15 years or less run on a different set of bands entirely. Look them up;
  do not reason by analogy from this diagram.

Contrast this with conventional mortgage insurance, which Chapter 5 introduced and which the Linden Street file uses. Under the Homeowners Protection Act, borrower-paid conventional MI on a principal residence must be terminated automatically when the loan reaches 78% of the original value on the amortization schedule, and the borrower may request cancellation at 80%. On the Linden Street conventional structure those happen at payment 137 and payment 125 respectively. The protection is statutory, automatic, and free.

FHA has no equivalent for loans above 90% LTV. The Homeowners Protection Act does not apply to FHA loans. There is nothing to request, no form to file, and no threshold to reach.

🧮 Run the Numbers

What the duration band is worth on the same house.

Same property, same rate, same annual factor, same term. The only thing that changes is the down payment. [Constructed teaching comparison on the Linden Street property; all FHA factors illustrative — verify current figures with HUD.]

	3.5% down	10% down
Down payment	\$13,475.00 | \$38,500.00
Base loan	\$371,525.00 | \$346,500.00
LTV at origination	96.50%	90.00%
UFMIP at 1.75%, financed	\$6,501.69 | \$6,063.75
Total loan amount	\$378,026.69 | \$352,563.75
P&I at 6.250%, 30 years	\$2,327.58 | \$2,170.80
Annual MIP at 0.55%	\$2,079.15/yr = \$173.26/mo	\$1,939.10/yr = \$161.59/mo
MIP duration category	life of the loan	11 years (132 payments)
Total annual MIP paid	\$62,374.40** | **\$21,330.11

The MIP totals: \$2,079.15 × 30 years = \$62,374.40, against \$1,939.10 × 11 years = \$21,330.11.

The difference is \$41,044.29.

The extra cash required to get there is \$38,500.00 − \$13,475.00 = \$25,025.00.

Now put the monthly side next to it. Adding taxes of \$385.00 and insurance of \$130.00 to each: the 3.5% structure is \$2,327.58 + \$173.26 + \$515.00 = **\$3,015.84, and the 10% structure is \$2,170.80 + \$161.59 + \$515.00 = **\$2,847.39. A monthly difference of \$168.45, which on its own pays back the \$25,025.00 in \$25,025.00 ÷ \$168.45 = 148.6 months, about twelve and a half years.

Read those two results together, because they teach opposite lessons. On monthly payment alone, the larger down payment is a twelve-year payback — unimpressive. Add the duration effect and the same \$25,025.00 also eliminates \$41,044.29 of premium. The payment comparison systematically understates the value of crossing 90%, because the thing you buy by crossing it is not a smaller payment. It is an end date.

And on this specific file, none of it is available. The Linden Street borrowers have \$38,000.00 in total verified assets. A 10% down payment is \$38,500.00 before a single closing cost. The option that would have solved the problem is the one they cannot reach, which is the ordinary condition of the borrowers this chapter is about.

🎓 NMLS Exam Watch

Mortgage insurance is one of the most heavily tested topics on the SAFE MLO test, and the questions live almost entirely in the differences between the two systems.

	Conventional MI (PMI)	FHA MIP
Who provides it	private mortgage insurance companies	FHA / HUD
Priced off credit score?	yes	no
Upfront premium	not typically	yes — UFMIP, financeable
Cancellation	Homeowners Protection Act: request at 80% of original value, automatic at 78%	none above 90% LTV at origination
Governing authority	HPA, investor guidelines	HUD Handbook 4000.1

The trap in the stem: a question will ask when mortgage insurance "cancels" on a 96.5% LTV FHA loan and offer 78%, 80%, and "when the borrower requests it" as distractors. All three are conventional answers. And watch for the reciprocal trap — a question asking what the borrower must do to cancel FHA MIP on that loan. The answer is that there is no cancellation available; the borrower refinances or pays it off.

Two more reliable items. UFMIP may be financed into the loan amount — candidates who assume it must be paid in cash miss this. And FHA loan-to-value is computed on the base loan amount before financed UFMIP, which is the distinction that makes 96.50% rather than 98.19% the right answer.

One more consequence, and it is the one that generates angry phone calls in year six. The borrower will not see this on any disclosure. The Loan Estimate and the Closing Disclosure show the monthly mortgage insurance and show it in the projected-payments table, but neither document announces "and this never goes away" in language a first-time buyer will register at a closing table where they are signing forty documents. If the borrower is going to understand life-of-loan MIP, they are going to understand it because you told them, in a sentence, on the phone, before they chose the program.

Say it this way: "On this structure the monthly mortgage insurance doesn't come off. Not at twenty percent equity, not at fifty. The only way out is to refinance into a conventional loan once you have twenty percent, and that's a decision for a few years from now with whatever rate exists then. I want you to hear that from me today rather than from a servicing rep in 2031."

16.6 The FHA appraisal and minimum property standards

Chapter 18 covers appraisal as a discipline — how value is developed, what the sales comparison approach does, and what happens when the number comes in short, as it does on Cypress Court. This section covers only the part that is FHA's and nobody else's.

An FHA appraisal does two jobs where a conventional appraisal does one. It develops an opinion of value, and it also certifies that the property meets HUD's minimum property requirements — a set of health, safety, security, and durability standards. The appraiser is, for this second job, acting as the eyes of HUD.

That second job is the source of nearly every FHA-specific surprise in a purchase transaction, and it is why listing agents in some markets have opinions about FHA offers.

What the minimum property requirements cover

The standards are about the property being safe, sound, and secure — safe to live in, structurally sound, and secure against the elements and intrusion. The recurring items, in the order they actually appear on condition sheets [illustrative; the enumerated requirements are in 4000.1 — verify]:

• Peeling, chipping, or defective paint on a home built before 1978 — the lead-based paint rule, and by a wide margin the most common FHA repair condition
• Roof condition — generally expected to have remaining useful life and to be free of active leaks
• Working, permanent heat source — a space heater is not a heating system
• Safe and potable water, and a functioning sewage disposal system — with well and septic testing where applicable
• Utilities on and operational at the time of inspection — an appraiser cannot certify a furnace they could not run, and a vacant foreclosure with the gas shut off will generate a return trip
• Handrails at stairs, safe access, adequate egress from bedrooms
• No evidence of structural failure, standing water in a crawlspace, or exposed wiring
• Legal access to the property, and no conditions that would make it unmarketable

When the appraiser finds one of these, the appraisal is completed "subject to" the repair. The loan cannot close until the repair is made and the appraiser (or in some cases another qualified party) certifies completion, which is a second appointment and a second fee. That is the calendar event.

Note what this is not: it is not a home inspection, it is not a warranty, and it does not protect the buyer. HUD is explicit about this and requires that the borrower receive a notice — "For Your Protection: Get a Home Inspection" — making the point in writing. Say it out loud too. An appraiser walking a property for MPR compliance is not going to find the failing HVAC compressor or the polybutylene supply lines. The buyer should still hire an inspector.

📄 Read the File

text FIGURE 16.2 — "Subject to repair, and nine days to closing" [constructed teaching example] THE DOCUMENT Uniform Residential Appraisal Report (Form 1004) with the FHA addendum, returned to the lender. Value opinion supported at the contract price. The appraisal is completed "subject to" repairs. THE CONTEXT An FHA 203(b) purchase of a 1962 single-family home. Nine days to the contract closing date. The buyers have given notice on their apartment and the movers are booked. WHAT IT SHOWS Value: supported at contract. No gap. Then, in the FHA section: "Subject to the following repairs or alterations: 1. Scrape and repaint peeling exterior paint, south and west elevations and detached garage (pre-1978 construction). 2. Install handrail at four-riser rear entry stair. 3. Repair broken window glass, rear bedroom (egress)." Estimated cost is not stated and is not the appraiser's job. WHAT IT DOESN'T It does not say who pays. It does not say who schedules the work. It does not say whether the seller will consent to work being done on a property they still own. It does not say how long the re-inspection takes to schedule, which is the number that actually decides whether this closes on time. And it does not tell you whether the peeling paint on two elevations is a weekend of work or a symptom of a substrate problem behind it. THE DECISION Today, not tomorrow: call the listing agent and the buyer's agent together, name the three items, and get one of two answers in writing — the seller does the work by a stated date, or the parties agree on an alternative and amend the contract. Simultaneously, ask the appraiser's office for their re-inspection lead time, because that number determines whether the closing date survives. Then tell your borrower the truth about the date before the movers are non-refundable. THE LESSON An FHA appraisal is a valuation AND a property inspection against HUD's standards, and the second half has its own calendar. A "subject to" finding is not a valuation problem and does not mean the deal is in trouble — it means somebody now has nine days to do three specific things, and the loan officer is the only person on the transaction whose job it is to notice that.

Constructed. Property conditions and requirements are illustrative; the current minimum property requirements are in HUD Handbook 4000.1 — verify.

Two FHA appraisal mechanics worth knowing

The appraisal is tied to the case number, and it travels with the borrower. An FHA appraisal is ordered against the FHA case number, and if the borrower changes lenders mid-transaction, the appraisal goes with the case number to the new lender. This is different from conventional practice and it is a real benefit to a borrower who has to switch — they do not pay for a second appraisal. It also means the value follows them, which is a real cost to a borrower whose appraisal came in short and who was hoping a new lender would produce a new number. It will not.

FHA appraisals have a validity period, generally measured in months from the effective date, with a defined extension path. [Verify the current period and extension rules with HUD.] On a long transaction — new construction, a delayed short sale, a repair dispute that drags — the appraisal can expire before closing, and an expired appraisal on day 60 of a 90-day mess is a genuinely bad morning.

16.7 Case numbers, CAIVRS, and the things that stop a file cold

Every FHA loan has a number, and everything hangs off it.

The FHA case number

The FHA case number is a unique identifier assigned by HUD, through FHA Connection, for a specific borrower and a specific property. It is requested by the lender early in the process — generally at or before the point the appraisal is ordered — and it is the thread that ties the appraisal, the underwriting, the insurance premium, and the endorsement together in HUD's systems.

Three things about it are operationally important.

The assignment date often controls which rules apply. Mortgagee letters routinely take effect for case numbers assigned on or after a stated date. That means the version of the premium schedule, or the guideline change, that governs your loan may be determined by a date that has nothing to do with when the borrower applied. When a premium changes, the case-number date is the first thing everyone looks at.

A case number is attached to a property and a borrower, and a stale one blocks the next file. If a transaction dies, the case number must be cancelled or transferred. If it is not, and the borrower comes back six weeks later on a different house — or a different buyer comes to you on the same house — the request for a new case number can fail. This is pure process hygiene, it is somebody's job at your shop, and when nobody owns it, files sit.

The appraisal belongs to the case number, per §16.6.

CAIVRS

CAIVRS — the Credit Alert Verification Reporting System — is a HUD-maintained federal database of people who are delinquent on, or have defaulted on, a federal debt. It is checked on every FHA borrower, and it is checked for every borrower and every FHA loan, not just the primary.

What lands a person in CAIVRS: a defaulted federally insured or guaranteed mortgage (FHA, VA, USDA), a defaulted federal student loan, a defaulted Small Business Administration loan, certain federal judgment liens, and other delinquent federal debt reported by the participating agency.

What a hit does: it makes the borrower ineligible for a federally related loan until the debt is resolved, or until an applicable exclusion or waiting period has run and the record is updated. It is not a scoring factor, not a compensating-factor question, and not something an underwriter can weigh against reserves. It is a stop.

  listing and selling agents, the lender, the appraiser, and other participants

  ─────────────────────────────────────────────────────────────────────────────────

Read that last box twice. A hit on a party who is not your borrower still stops your file. A loan officer who does not know this discovers it at submission, which is the worst possible time.

The other FHA-specific stops

Property flipping restrictions. FHA restricts financing on a property being resold shortly after the seller acquired it, because rapid resale at a markedly higher price is a documented fraud pattern. The structure has long been: a resale within a short window after acquisition is generally ineligible, and a resale in a somewhat longer window at a substantially higher price triggers a second appraisal requirement. [Verify the current windows, price thresholds, and exceptions with HUD.] The practical consequence lands on an agent, not a borrower: an investor who bought a house at auction six weeks ago cannot sell it to your FHA buyer, and nobody finds out until the title commitment shows the acquisition date. Ask about the seller's acquisition date on any file where the house has obviously just been renovated.

One FHA loan at a time, with defined exceptions. A borrower is generally limited to one FHA-insured mortgage at a time. The exception categories are narrow and specific, and the relocation exception is where the 100-mile rule in §16.8 lives.

Delinquent federal tax debt is its own screen, distinct from CAIVRS. A documented payment plan with a payment history may make the borrower eligible; the payment counts in the debt-to-income ratio. [Verify current requirements.]

The property must be eligible. A property that fails minimum property requirements is not eligible until the condition is cured. A condominium must be in an approved project or qualify under the single-unit review process. [Verify current condominium approval requirements with HUD.]

⚠️ Where Deals Die

The CAIVRS hit that surfaces at submission.

Here is the shape of it. A borrower had an FHA loan on a house with a former spouse. The divorce decree awarded the house and the debt to the ex-spouse. The ex-spouse stopped paying. The property went to foreclosure and FHA paid a claim. Nothing about that appears as a problem on the credit report today, because the mortgage tradeline is nine years old and has long since dropped off, and the borrower — completely sincerely — tells you they have never had a mortgage problem.

Then the file is submitted and the CAIVRS check returns a hit.

What it costs: the file stops. Not "gets a condition" — stops. The resolution path, if there is one, runs through documentation of the claim and the applicable exclusion period, and it is measured in weeks, not days. If there is a contract with a closing date on it, the closing date is gone.

What the disciplined originator does: ask the federal-debt question at application, explicitly, as its own question, in its own words. "Have you ever had a government-backed loan — FHA, VA, USDA, a federal student loan, an SBA loan — that went to foreclosure, default, or collection? Even if it was a long time ago, and even if it was somebody else's fault?" Then get the case screened as early in the process as your shop's workflow allows.

And note the human dimension, because it is the whole reason this one is hard: the borrower is not lying to you. They believe what they told you. A divorce decree that assigns a debt does not release the borrower from it, and nobody ever explained that to them. You will be the person who does, and you should do it gently and early rather than accurately and late.

16.8 Identity of interest, non-occupant co-borrowers, and 100-mile rules

Three FHA rules that share a common logic: FHA cares about the relationships around the transaction, not just the numbers in it.

Identity of interest

An identity of interest transaction is a sale between parties with a family relationship or a business relationship — a borrower buying from a parent, from a sibling, from an employer, from a company they have an interest in, or from a business associate.

FHA's default treatment is to restrict the maximum loan-to-value on such a sale, commonly to 75%, because a non-arm's-length sale is a documented vehicle for value manipulation: a "price" agreed between related parties is not the same evidence of market value as a price agreed between strangers.

There are defined exceptions that restore the standard LTV, and they cover the situations where a related-party sale is obviously legitimate — a family member buying from a family member as a principal residence, a tenant of a documented duration purchasing the property they have been renting, an employee purchasing from an employer under a relocation program, and similar cases. [Illustrative summary; the exception categories and the LTV restriction are in 4000.1 — verify the current rule with HUD.]

The practitioner point: this is a question you ask at application, and it is not obvious to the borrower that it matters. "Do you know the seller? Are you related to them, do you work for them, or do you have any business relationship with them?" If the answer is yes, you find out before you issue a pre-approval, because the difference between 96.5% and 75% loan-to-value on a \$215,000 house is \$46,225.00 of down payment that nobody has.

Check that: \$215,000 × 0.965 = \$207,475.00 against \$215,000 × 0.75 = \$161,250.00. The difference is \$46,225.00. That is not a condition. That is a different transaction.

Non-occupant co-borrowers

FHA permits a non-occupant co-borrower — someone who signs the note and takes on liability for the debt but will not live in the property. The classic case is a parent helping an adult child qualify.

FHA's treatment has two distinctive features. First, the non-occupant co-borrower's income and debts are combined with the occupying borrower's, so the ratios are computed on the household as a whole — which is why the structure works at all. Second, and this is the part that surprises people, FHA restricts the maximum LTV when the non-occupant co-borrower is not a family member, on the same 75% logic as identity of interest. A parent, sibling, or child co-borrower generally preserves the standard LTV; a friend, a business partner, or a fiancé may not. [Verify the current family-member definition and LTV treatment with HUD — the definition of "family member" for this purpose is specific and is enumerated in the handbook.]

There is also a hard line that has nothing to do with LTV: a co-borrower with an interest in the sale cannot be a non-occupant co-borrower. The seller cannot co-sign. Neither can the builder or the agent. This is the same principle as §16.4's interested-party rule, applied to liability rather than to funds.

Chapter 13 covered structure generally, including when adding a borrower helps and when it hurts. The FHA-specific addition is only this: on FHA, adding the wrong non-occupant can cost you twenty-one and a half points of loan-to-value, which is usually the whole deal.

The 100-mile rules

FHA uses a 100-mile distance threshold in two related places, and they are easy to conflate.

Relocation. A borrower who already has an FHA-insured mortgage may be permitted a second one when they are relocating for employment to a new principal residence more than 100 miles from the current one. This is one of the narrow exceptions to the one-FHA-loan-at-a-time rule.

Rental income from a vacated principal residence. When a borrower is moving out of a property they own and intends to rent it, FHA restricts whether the rental income may be used to offset the payment on that property. The 100-mile distance is one of the conditions in that analysis, alongside a documented lease and evidence of the security deposit or first month's rent. Where the conditions are not met, the borrower carries both housing payments in the debt-to-income ratio, which is usually decisive.

[Both rules are illustrative summaries. Verify the current relocation exception and rental-income conditions with HUD — the details, including how the distance is measured, matter and have been revised.]

The reason to know these cold is that they are pre-approval questions, not underwriting questions. A borrower who says "we're keeping the old house and renting it out" has just told you something that may add \$1,600 a month to their debt-to-income ratio. Find out on day 1, not day 23.

16.9 Streamline refinances

FHA's streamline refinance is a refinance of an existing FHA-insured mortgage into a new FHA-insured mortgage with substantially reduced documentation. It exists for a reason that follows directly from §16.1: FHA is already insuring this loan. If the borrower's payment goes down, FHA's risk goes down, and the insurance fund benefits. There is no reason to re-underwrite the borrower from scratch to achieve that.

The core requirements

[Illustrative summary — every one of these has specific current requirements in 4000.1 and in mortgagee letters. Verify with HUD before you quote.]

• The existing loan must be FHA-insured. This is the one that eliminates most callers. A conventional loan cannot be streamlined into FHA; that is an ordinary FHA refinance with full documentation.
• Seasoning. A minimum number of payments must have been made and a minimum period must have elapsed since the existing loan closed. The structure has generally combined a payment count with a days-since-closing requirement.
• Payment history. The borrower must be current, with a clean recent mortgage payment history.
• Net tangible benefit. The refinance must produce a defined benefit to the borrower — a specified reduction in the combined interest rate and annual MIP, a move from an adjustable rate to a fixed rate, or a defined term reduction. This is a test with a numeric threshold, not a judgment call.
• Limited cash out. A streamline is not a cash-out product. The borrower may receive only a nominal amount at closing.
• No new appraisal required on the non-credit-qualifying path.

Credit-qualifying versus non-credit-qualifying

Two paths, and knowing which one you are on determines what you have to collect.

The non-credit-qualifying streamline is genuinely fast, and it is where the product's reputation comes from. Be careful about two things anyway. First, lender overlays are heavy here — many lenders impose a minimum credit score and a full credit report on a product where HUD does not. Ask your shop what it actually does before you promise a borrower a two-week close. Second, no appraisal does not mean no value question: the loan amount is capped by a formula built on the existing principal balance rather than on a new value, so a borrower who wants to roll in closing costs may find they cannot.

The two premium mechanics that decide whether it is worth doing

The UFMIP refund. When a borrower refinances one FHA loan into another within a defined period, a portion of the original upfront premium is refunded and credited toward the new UFMIP, on a declining schedule that reaches zero after a few years. [Verify the current refund schedule with HUD.] This is real money and it is frequently forgotten in the net-benefit conversation.

The duration category resets — but usually to the same place. This is the §16.5 tie-back, and it is the most important thing in this section.

A streamline creates a new loan, and the new loan gets its own MIP duration determination. But because there is no new appraisal, the LTV on the new loan is computed using the original appraised value. A borrower who bought at 96.50% and has paid down to, say, 91% against the original value is still above 90%, and lands in the life-of-loan band again. A borrower whose house has doubled in value gets no credit for it, because nobody appraised it.

A streamline is therefore usually not an exit from life-of-loan MIP. The exit is a conventional refinance, once there is genuinely 20% equity based on a current appraisal, at whatever rate exists that year. Say this to borrowers plainly, because "just streamline it later" is advice they will hear from someone.

One genuine bright spot: FHA has long maintained a reduced-premium streamline path for loans endorsed on or before a cutoff date in 2009, carrying markedly lower upfront and annual premiums than the standard schedule. If a borrower brings you an FHA loan from that era, look it up before you quote anything, because the difference is large enough to change the answer. [Verify the cutoff date and the applicable premiums with HUD.]

🔍 Check Your Understanding

1. A borrower has an FHA loan at 96.50% original LTV, taken four years ago. Their home has appreciated 30% and they have paid the balance down. They ask you to streamline them into a lower rate and get rid of the monthly MIP. Which half of that request can you deliver?
2. Your borrower's minimum decision credit score is 612 and their back-end ratio is 46%. TOTAL returns an Approve/Eligible. Your colleague says "you can't do that, FHA caps at 43." What is wrong with the sentence?
3. A file needs \$13,475.00 of minimum required investment. The seller has offered a \$14,000 credit "to cover the down payment and some costs." What is the problem, and what part of the offer might still be usable?

(1: the rate, not the MIP — no new appraisal means the LTV is computed on the original value, so the duration band almost certainly repeats. 2: "43" is the base cell of the MANUAL underwriting ratio table; a file with an Approve/Eligible is not measured against it. 3: a seller may not fund the MRI directly or indirectly — the credit can go to closing costs, prepaids, and points up to the permitted interested-party contribution limit, but the \$13,475.00 must come from the borrower or an acceptable non-interested source.)

16.10 FHA vs. conventional: running the real comparison

Now put it together on a real file.

On day 2, before the borrowers had a contract, you priced Linden Street both ways. Chapter 13 took the decision — conventional, 95% — and this section shows the analysis that supported it. This is not a re-litigation. It is the worked example of a comparison you will run several hundred times in a career, and the point is the method, which generalizes, not the answer, which does not.

The comparison as it was run

[Constructed teaching comparison — the Linden Street file. All FHA factors, MI factors, and rates are illustrative. Verify current figures with HUD and with your rate sheet.]

Three headline results, and they point in different directions:

**FHA is \$17.88 per month cheaper.** \$3,033.72 − \$3,015.84 = \$17.88.

**FHA needs \$5,775.00 less at the closing table.** \$19,250.00 − \$13,475.00 = \$5,775.00.

**FHA costs \$38,155.54 more in mortgage insurance.** \$62,374.40 − \$24,218.86 = \$38,155.54.

The conventional MI figure is \$176.78 × 137 payments = \$24,218.86 — it terminates automatically at 78% of original value under the Homeowners Protection Act. The FHA figure is \$2,079.15 × 30 years = \$62,374.40 — it does not terminate at all. That single structural difference is the entire comparison. Everything else on the table is noise by comparison: seventeen dollars and eighty-eight cents a month, against thirty-eight thousand dollars.

Widening the frame: total cost over the full term

The monthly comparison flatters FHA and the mortgage-insurance comparison flatters conventional. Neither is the whole picture, because the two loans are different sizes at different rates. Add everything up. [Both columns use 360 level payments and hold the MI/MIP installment constant, the same simplification on both sides.]

The FHA structure costs \$27,210.94 more across the full term. Note that this is less than the \$38,155.54 mortgage-insurance gap, because the FHA loan's lower note rate gives back about \$17,000 of interest — a real offset, and the reason you cannot answer this question by comparing mortgage insurance alone.

Narrowing the frame: what happens in ten years

Nobody holds a thirty-year mortgage for thirty years. So run the horizon that actually applies.

Over 120 payments, cash out of pocket:

FHA is \$7,920.60 cheaper over ten years. And then the offset: the FHA borrower financed \$12,276.69 more to begin with, and at month 120 still owes roughly **\$318,400 against the conventional loan's \$311,034.26** — about **\$7,400 more debt. (The FHA balance is a closed-form figure; a servicer's schedule will land within a few dollars.)

Put those together and the two structures are within roughly \$500 of each other at the ten-year mark. On a \$385,000 house, over a decade, that is a rounding error.

Which is the most useful result in this section. For the first decade these two loans are the same deal. The entire difference arrives in year eleven and after, when the conventional borrower's mortgage insurance has been gone for a year and the FHA borrower's has nineteen years left to run. The FHA-versus-conventional question is not a question about the closing table. It is a question about year eleven, and you are asking it of people who are thinking about a move-in date.

🧮 Run the Numbers

The four questions that decide the program, in the order you should ask them.

1. Can the borrower produce the larger down payment at all? If the honest answer is no, the comparison is over and FHA wins on feasibility. On Linden Street the answer was yes: \$38,000.00 verified, \$25,376.34 required to close conventionally, leaving \$12,623.66 = 4.16 months of reserves. The FHA path would have left more cash — but they did not need more cash. The relief was convenience, not feasibility. That is the sentence that decided the file.

2. Will conventional mortgage insurance even be available, and at what price? Conventional MI is priced off the credit score; FHA MIP is not. At a 706 representative score and 95% LTV, the Linden Street factor is 0.58%, producing \$365,750.00 × 0.0058 ÷ 12 = **\$176.78 — barely more than the FHA premium. At a 640, the same coverage costs multiples of that, if a mortgage insurer will write it at all. This is the question that flips the answer, and it flips it hard.**

3. Will the file get an approval on the conventional path? Ratios, reserves, and credit history all bind more tightly on conventional than on FHA. A back-end ratio in the high forties with an FHA Approve/Eligible may have no conventional counterpart at any price.

4. How long will they hold this loan, and where does the MI end? Conventional MI ends at payment 137 on this file. FHA MIP does not end. Over ten years the difference is \$500; over thirty it is \$27,210.94. If the borrower will refinance or sell inside a decade, question 4 nearly cancels out. If they will hold it, question 4 is the whole thing.

The order matters. New loan officers run question 4 first because it produces the most dramatic number, and then discover the borrower cannot pass question 1. Run feasibility, then pricing, then approvability, then cost.

The borrower for whom the answer flips

Now run the same four questions on Harlow Street, where every one of them comes out the other way.

Take that file to the conventional side. A 3% down conventional structure on a \$215,000 purchase is a \$6,450.00 down payment and a \$208,550.00 loan at 97.00% LTV. Assume, purely for illustration, that a mortgage insurer will write coverage at this borrower's 641 score and 97% LTV at a 1.55% annual factor, and that the note rate after credit and LTV adjustments is 7.250%. [Constructed teaching comparison. Conventional MI factors are set by the mortgage insurers and change; note-rate adjustments are set by the investors and change. Verify both at the source — and note that at this score and loan-to-value, coverage may simply be unavailable.]

The conventional structure costs \$295.49 more per month** — \$2,017.06 − \$1,721.57 — and produces a 58.12%** back-end ratio that no automated underwriting system is going to approve. And the mortgage insurance line is doing almost all of the damage: \$269.38 against \$96.76, on a smaller loan, entirely because conventional MI is priced off a 641 score and FHA MIP is not.

That is the flip, and it is worth stating as a rule:

Conventional is usually cheaper for a borrower with a strong score who will build equity. FHA is usually cheaper — and frequently the only option — for a borrower whose score, ratios, or credit history make conventional mortgage insurance expensive or unavailable.

The Linden Street borrowers have a 706 and the cash. The Harlow Street borrower has a 641, a 51.00% back-end ratio, and a down payment funded entirely by a county program. Same product, opposite answers, and the deciding variable in both cases is what the mortgage insurance costs and how long it lasts — not the down payment, which is the only thing either borrower asked about.

A closing note on how you say this

There is a version of this section that reads as a technique for talking borrowers out of FHA. It is not. Steering a borrower toward a more expensive product, or discouraging an application, is a fair-lending problem before it is anything else, and Chapter 25 treats it at length. The obligation here runs the other way: run the comparison honestly, in dollars, for the specific file, and let the borrower decide. Show both. Write both down. If the answer is FHA, say so with the same confidence you would say conventional, and never let a program preference — yours or your shop's — substitute for the arithmetic.

🗂️ The Loan File

Chapter 16 contribution: price the file as FHA, and record why it was not.

On day 2 — Friday, the day after the discovery call and two days before the offer was accepted — you priced Linden Street as an FHA 203(b) file, side by side with the conventional structure. The borrowers had asked about FHA on day 1. They were also shopping an online lender advertising a lower rate, which is the ordinary condition of every first-time buyer with an internet connection and which Chapter 40 returns to. What follows is what you actually put in front of them.

The FHA structure as priced:

Against the conventional 95% structure: PITI + MI \$3,033.72, back-end 42.66%, MI terminating automatically at payment 137, total MI \$24,218.86.

The three numbers, stated to the borrowers in this order:

1. FHA saves \$5,775.00 at the closing table.
2. FHA saves \$17.88 a month.
3. FHA costs \$38,155.54 more in mortgage insurance, because it never comes off.

What this settles. The program. Chapter 13 structured the file conventional at 95%, and this is the analysis that supported it. The deciding fact was not the payment and not the down payment: it was that these borrowers had the \$19,250.00 and would still hold 4.16 months of reserves after closing. FHA's down-payment relief was convenience, not feasibility — and \$5,775.00 of convenience is not worth \$38,155.54, particularly when the financed UFMIP of \$6,501.69 exceeds the cash saved by \$726.69 all by itself.

What it does not settle. Whether the borrowers will actually hold this loan long enough for the thirty-year comparison to be the relevant one. Over the first ten years the two structures are within roughly \$500 of each other, and if this household refinances or moves in year seven, the analysis above was mostly theater. You cannot know that on day 2, and the honest position is to say so: the conventional structure is better if you keep it, and a coin flip if you don't, so we are choosing the one that is better in the case we can't rule out.

What it also does not settle: whether a 706 representative score is the score this file will actually price at on lock day, and whether the appraisal will support \$385,000. Both are still open.

Open questions carried forward:

• Q2 (closed). Which program — conventional or FHA? Conventional, 95%. Chapter 13 decided it; this chapter shows the work.
• Q3. Will an appraisal support \$385,000? (Chapter 18 — and note that on the conventional path the appraisal is a valuation only, with none of §16.6's property conditions attached.)
• Q7 (new). If this household is still in the house in year eleven, does the conventional structure's terminated MI change what they should do with the freed-up \$176.78? (Chapter 23.)

Your task. In Appendix C's workbook, complete the FHA column of the program comparison page using the figures above, and then add one line the comparison table does not have: the date the mortgage insurance ends, under each structure. For the conventional loan, write "payment 137." For FHA, write the word that belongs there. Then write one sentence explaining that difference to a borrower who has never heard the term "loan-to-value" — in under twenty-five words, without using a percentage sign.

Conclusion

FHA is an insurance program, not a lender. It was built in 1934 to make long-term, low-down-payment lending possible by covering the lender's credit loss, and that is still precisely what it does. The rulebook is HUD Handbook 4000.1, amended continuously by mortgagee letters whose effective dates are usually keyed to the FHA case number — which is why the working habit is check the handbook, then check the letters, and never quote a premium from memory.

The two things most often gotten wrong are the ratio benchmark and the premium duration.

The 31%/43% figure is the base cell of the ratio table for manually underwritten files, and it rises as documented compensating factors are added. It is not a cap on FHA approvals. A file with an Approve/Eligible from the TOTAL Scorecard is not measured against it — which is why Harlow Street is approvable at 41.48% / 51.00% with a \$1,721.57** payment against **\$4,150.00 of income, and why an originator who declines that borrower on a remembered "43" has misapplied a real rule to the wrong path.

The premium duration is the rule that decides the money. The loan-to-value at origination sets the MIP duration category, and the category is set once at closing and never revisited: 90% or less gets eleven years, above 90% gets the life of the loan. A borrower putting the minimum 3.5% down lands at 96.50% and can never reach the eleven-year band — not by paying the balance down, not by appreciation, not by a new appraisal. Conventional mortgage insurance terminates automatically at 78% of original value under the Homeowners Protection Act. FHA's does not terminate at all.

On Linden Street that difference is worth \$38,155.54**, against **\$5,775.00 less at the table and \$17.88 a month — and the borrowers had the cash, so the relief was convenience rather than feasibility. That is why Chapter 13 chose conventional. On Harlow Street, where a 641 score makes conventional mortgage insurance cost \$269.38** instead of **\$96.76 and pushes the back-end ratio to 58.12%, every one of those factors reverses and FHA is the only structure that works. Same product, opposite answers, one deciding variable: what the mortgage insurance costs, and how long it lasts.

Every factor, threshold, and band in this chapter is illustrative and every one of them has moved. Verify current figures with HUD before you quote them.

Next: VA and USDA — two more government programs, built for two entirely different populations, with a funding fee that behaves nothing like UFMIP and, in the VA's case, no monthly mortgage insurance at all. Chapter 17 also settles a counterfactual this chapter did not run: what the Linden Street payment would have been with a VA entitlement neither of these borrowers has.

Spaced Review

1. (Ch.16) A borrower puts 3.5% down on a \$400,000 FHA purchase and, six years later, has paid the balance down and watched the home appreciate to \$520,000. They call asking how to get the monthly MIP removed. Answer them in three sentences, and name the only two things that would actually end the premium.

2. (Ch.5 + Ch.16) Chapter 5 introduced conventional and FHA as program categories and named the difference between PMI and MIP. Using nothing but the mortgage insurance line, state the single structural reason a 780-score borrower with 5% down should almost always be conventional and a 620-score borrower with 3.5% down should almost always be FHA.

3. (Ch.15 + Ch.16) Your file returns an Approve/Eligible through TOTAL with a 47% back-end ratio. The processor says the underwriter will "have to downgrade it because it's over 43." Identify the two distinct errors in that sentence — one about what 43 is, and one about what a downgrade is and what actually triggers one.

4. (Ch.16) Compute, showing both figures: on a \$385,000 FHA purchase at the 3.5% minimum required investment with UFMIP financed at 1.75%, how much cash does the borrower save against a 5% conventional down payment, and how much does the financed UFMIP add to the loan? State in one sentence why those two numbers together make "FHA needs less money down" an incomplete claim.

5. (Ch.15 + Ch.16) Chapter 15 established that an AUS recommendation is a recommendation about the file, not a promise about the borrower. Apply that to Harlow Street: the file has an Approve/Eligible at a 51.00% back-end ratio and a \$1,721.57 payment on \$4,150.00 of income. Write the two sentences you would say to that borrower before submission — one about what the approval means, and one about what it does not.
