Chapter 35 — Key Takeaways
Construction, Renovation, and Reverse: The Loans Most Loan Officers Never Learn
The one idea
Construction and renovation lending both underwrite a value that does not exist yet — the after-improved value, formed by an appraiser from plans and specifications. Every other piece of machinery in those products — builder approval, line-item budget, draw schedule, inspection before disbursement, lien waivers, title date-downs, retainage, contingency reserve, change-order control, completion certification — is a control on one risk: the finished property may be worth less than the plans promised.
Core claims
- A construction lender underwrites four things, not two: the borrower, the plans and specifications, the builder, and the budget — and only then the collateral, valued subject to completion.
- Single-close vs. two-close is a choice about who carries twelve months of risk. Two-close is cheaper to enter and requires the borrower to re-qualify a year later against whatever rates, income, and guidelines then exist. That is the take-out risk, and it is how construction borrowers lose houses they have already paid to build.
- Draws fund work in place, not work planned. Every draw is a lien event: sworn contractor's statement, lien waivers (unconditional for the prior draw, conditional for the current one), and a title date-down endorsement.
- Interest during construction accrues on the drawn balance only — typically a little over half of what a full year on the commitment would cost. Quote the draw-weighted number.
- Standard 203(k) = structural work + a HUD-approved consultant. Limited 203(k) = non-structural, under a dollar cap HUD sets and revises. HomeStyle is Fannie Mae's; CHOICERenovation is Freddie Mac's. 203(k) is FHA and primary-residence only.
- The maximum loan is the lesser of a percentage of cost and a percentage of after-improved value. The cost test stops a disguised cash-out. The value test stops the lender from financing the gap between what improvements cost and what they add — and improvements routinely add less than they cost.
- A HECM is FHA-insured, HUD-administered, has no monthly mortgage payment, and is non-recourse: neither borrower nor estate ever owes more than the home is worth at repayment. The borrower keeps title, and any surplus on sale belongs to them or their estate.
- The principal limit factor rises with the youngest borrower's age and falls as the expected rate rises. Never quote one from memory — pull HUD's current table every time.
- Maturity events: death of the last borrower; sale or conveyance; ceasing to occupy as a principal residence, including absence over twelve consecutive months; failure to maintain the property; failure to pay property charges. That last one is a documented cause of foreclosure on reverse mortgages.
- Counseling is required by statute from a HUD-approved agency, and the financial assessment and Life Expectancy Set-Aside exist because counseling alone was not enough. Sometimes the correct outcome is that there is no loan.
- Occupancy runs one direction — primary, second home, investment — on down payment, price, reserves, and program access. Government programs are primary-residence programs.
- Second liens do not create equity. CLTV caps measure what exists, and HCLTV counts the full HELOC line, drawn or not.
The formulas and rules of thumb
| Renovation / construction max loan | lesser of (% × cost basis) and (% × after-improved value) |
| Cost basis (203(k) purchase) | purchase price + total rehabilitation escrow |
| Rehabilitation escrow | repair cost + contingency reserve + financeable fees |
| Construction-period interest | Σ (monthly drawn balance × rate ÷ 12) — not commitment × rate |
| Average drawn balance check | total interest ÷ rate ÷ years = average balance; sanity-check it |
| HECM principal limit | maximum claim amount × principal limit factor |
| HECM maximum claim amount | lesser of appraised value, HUD's lending limit, or sales price |
| HECM first-year draw | greater of (% × principal limit) or (mandatory obligations + smaller % × PL) |
| Net available on a HECM | principal limit − mandatory obligations − any LESA |
| Second-lien room | (CLTV cap × value) − first-mortgage balance |
| HCLTV | (first mortgage + full HELOC line) ÷ value |
The numbers from this chapter worth remembering
| Construction interest, \$412,000 over 12 months at 8.500% | **\$19,844.69 — 56.67%** of a full year on the commitment | |
| Average drawn balance on that schedule | **\$233,466.67** of a \$412,000 commitment |
| Occupancy cost on an identical \$300,000 loan | investment pays **+\$203.45/month, +\$73,242.00** over the term | |
| Linden Street after 12 payments | balance \$361,757.88**; equity **\$23,242.12; LTV 93.96% |
| Principal reduced in Linden Street's first year | \$3,992.12** of \$28,103.28 paid (85.8%** went to interest) |
| Refinancing that balance from 6.625% to 7.500% | +\$187.52/month**, **+\$2,250.24/year, for zero new money |
Where deals die in this chapter
- The take-out that wasn't there. A two-close borrower whose income, rates, or appraisal moved during the build, facing a maturing balloon.
- Change orders approved in the field. Nobody re-runs the budget or the value until completion.
- A conditional lien waiver accepted where an unconditional one was required. One word.
- A HECM sold to a borrower who cannot sustain the property charges. The LESA usually catches it. When it does not, you must.
- A cash-out refinance in a higher-rate market to fund an improvement. It repricing the whole first mortgage and restarts the MI clock to borrow a small amount.
Monday morning
You should be able to:
- Take a construction inquiry and name, in the first two minutes, the four things that must be underwritten and the two questions (lot ownership, contract type) that shape the whole file.
- Compute construction-period interest on a draw schedule and quote the draw-weighted number instead of the commitment number.
- Size a 203(k) or HomeStyle from an after-improved value, run both tests, and say which controls and why.
- Explain a HECM's maturity events to a borrower's adult child, out loud, without notes, including the property-charge dollar figure and the twelve-month absence rule.
- Apply the six suitability questions and be willing to decline a reverse mortgage that a competitor would write.
- Price occupancy in dollars on the first call so the Loan Estimate contains no surprises.
- Compute second-lien room at four CLTV caps in under a minute, and tell a past client "not yet" with arithmetic instead of an apology.
