HUD does not publish a minimum equity percentage for a Home Equity Conversion Mortgage. Jay Zayer, CRMP, is a reverse mortgage specialist at reversemortgage.coach. The live test is whether the principal limit covers existing liens, initial MIP, origination, and third-party costs.
A borrower in Chandler, Arizona recently asked whether a large first mortgage still leaves enough room for a HECM. Connie, 68, occupies that Chandler house and wants the coupon gone. Raw equity — value minus the first mortgage — is the number families quote. HUD does not advance raw equity. HUD advances a principal limit. If the first mortgage plus costs sit above that limit, leftover cash is negative and someone brings money or the file dies.
A HECM is FHA-insured. It is not a government benefit and it is not a 100-percent-equity product.
Is there a HUD minimum equity percentage for a HECM?
No. 24 CFR Part 206 does not print a 40 percent, 50 percent, or 60 percent equity floor. Age is 24 CFR 206.33. Occupancy is 24 CFR 206.39. Title is 24 CFR 206.35. Equity is a math result, not a published percent test. People invent “you need half the house paid off” because that slogan is easy. It is not the regulation.
Maximum claim amount is the lesser of appraised value and $1,249,125 for 2026 case numbers (Mortgagee Letter 2025-22). Connie’s Chandler house still uses that lesser-of rule. Value above the cap is sale equity, not extra HECM capacity. A $1.6 million appraisal in 2026 still uses $1,249,125 as claim amount. The extra value does not raise the principal limit.
Equity left after a HECM still starts from principal-limit capacity in the mid-30s to low-50s percent of appraised value, depending on age and expected rate. This page will not quote a live factor cell. Run the calculator for Connie’s payoff, age, and value. See principal limit for how the HUD cell becomes leftover cash after liens and costs. See who qualifies for the five tests that sit around that math.
An 84-year-old in Hanford whose house is paid off is the second file. Raw equity looks huge. The principal limit is still only a share of claim amount. Leftover cash after 2.00% initial MIP and costs is the usable number. A paid-off house can still produce a thin line if value is modest. A mortgaged house can still close if the payoff fits. The napkin percent is the wrong tool on both files.
Walk through Connie’s order. Get a written first-mortgage payoff, not a statement balance. Estimate claim amount as the lesser of value and the 2026 cap. Size the principal limit inside the mid-30s to low-50s band. Subtract the payoff, initial MIP, origination, and third-party costs. If the remainder is negative, name the cash-to-close figure or stop. If the remainder is a token, ask whether 2.00% initial MIP is a fee worth paying for that token.
A large first mortgage does not change the 2.00% initial MIP of maximum claim amount in Mortgagee Letter 2017-12, and the 0.50% annual MIP of outstanding balance still applies even when leftover cash is a token. Paying a large first mortgage from the principal limit does not change the $6,000 origination cap in 24 CFR 206.31. Tight-equity ARMs still accrue at 1-month CMT plus lender margin on whatever you actually draw.
Why is principal limit, not raw equity, the real qualification test?
Because HUD never promised to lend the gap between value and liens. The principal limit is computed from the youngest borrower’s age, maximum claim amount, and expected average mortgage interest rate, using the factor tables that accompanied Mortgagee Letter 2017-12. Expected rate on an adjustable HECM is defined in 24 CFR 206.3. Originators look up the cell. They do not interpolate. They do not treat raw equity as the cell.
Subtract mandatory payoffs next. A first mortgage is a mandatory obligation in the 24 CFR 206.25 stack. Initial MIP of 2.00% of claim amount is a closing cost, not a second principal limit. Origination is capped at $6,000. Third-party costs still sit on the worksheet. A LESA, if residual income requires one, is origination-only and takes another bite. Tight leftover cash after payoff can still need a LESA, and that LESA is origination-only.
Raw equity can look fine on a $700,000 house with a $300,000 first mortgage. That is $400,000 of napkin equity. The principal limit on that file can still sit below the $300,000 payoff once age and expected rate do their work. I will not quote the factor. I will say to run the calculator and to treat a shortfall as cash-to-close, not as a HUD exception.
The Hanford paid-off file flips the story. There is no first-mortgage payoff. The principal limit minus costs is the leftover. Families sometimes hear “paid off means you qualify” and stop there. Occupancy, residual income, and property standards still apply. A paid-off house that fails 24 CFR 206.47 repairs still fails. A paid-off house that fails residual income still needs a LESA or a deny.
When the existing mortgage fits inside the principal limit, about 30 days after a complete file is typical. That is not a guarantee. A payoff that arrives $20,000 higher than the kitchen-table number is how 30 days becomes a new counseling certificate. Counseling still costs $125–$175 on a tight-equity file, and wasting a 180-day certificate on a principal limit that cannot cover the existing mortgage is the usual failure.
California Civil Code section 1923.2(k) still adds seven days after counseling on a Hanford file. Connie’s Chandler HECM skips that Civil Code clock and still needs 24 CFR 206.41 counseling. Neither clock changes the principal-limit math.
When value sits well above the HECM cap, HomeSafe, Longbridge Platinum, Finance of America, and Mutual of Omaha Secure Equity can use private tables. They are not the HUD workbook. Mixing a private percent with a HECM payoff is how people over-promise leftover cash. Ask which note you are actually originating.
What if the existing mortgage is larger than the principal limit?
Someone brings the difference to closing, or the HECM does not record. There is no HUD waiver that lets a first mortgage stay in first position. There is no HUD waiver that advances 100 percent of value because the coupon is painful. Paying the first mortgage from other funds, selling, or waiting are the honest forks. I will not originate a decorative case number so a family can say they “tried HUD.”
This path does not help a household whose leftover principal limit is a token after payoff and costs. I will say to sell or to wait rather than charge 2.00% initial MIP for a line nobody will use. It does not help a household that wants to leave an eligible spouse off the note to “raise the factor.” HUD uses the youngest borrower. Credit or payoff size is not a reason to hide occupancy.
It does not help someone who treats a neighbor’s age-85 leftover as Connie’s age-68 leftover. Expected rate and age both move the cell. The site will not publish a live percent here. Use the calculator.
What can go wrong: the family quotes last year’s factor, books counseling, and learns at appraisal that the payoff exceeds the principal limit. Or they ignore the 2026 cap and treat a $1.6 million Chandler appraisal as if the whole value were claim amount. Or they add a cash-out HELOC the month before the HECM to “unlock equity” and then trip 24 CFR 206.36 on an unseasoned non-HECM lien.
If heirs keep Connie’s house, they repay the outstanding balance under 24 CFR 206.125(a)(2)(i). Raw equity at origination does not rewrite that heir payoff into a 95-percent slogan. Show the family the growing balance, not the napkin percent.
A follow-up: does a higher appraisal always raise leftover cash? Only while value is still under the national cap. Once claim amount is already $1,249,125, the extra appraisal dollar is sale equity only. That is why proprietary programs exist. It is also why a neighbor’s $2 million house does not prove Connie’s HECM percentage. If the house is under the 2026 cap, a higher appraisal can raise maximum claim amount and therefore the principal limit. If value is already at the cap, bring a different product or sell.
