The HECM for Purchase down payment is not a HUD flat 20%. Jay Zayer, CRMP, is a reverse mortgage specialist at reversemortgage.coach. 24 CFR 206.44 builds required monetary investment as purchase price minus principal limit plus HECM loan-related fees not paid by the principal limit, minus earnest money. Principal limit follows the lesser of price and $1,249,125 for 2026, times a factor that moves with age and expected rate. Amounts vary. Run the purchase calculator.
A borrower in Mesa, Arizona, recently: Nia, 75, looking at a $750,000 one-story. At the site’s 7.000% expected-rate assumption as of 22 September 2026, hecm-factors.md shows about $475,000 cash including a $25,000 closing-cost stack on that $750,000 price — 63.3% of price. That is a worked site example, not a live lock. See HECM for Purchase process for sequence. Stay here for the dollars.
A HECM remains FHA-insured. Required investment is not a government matching grant.
What is the actual 24 CFR 206.44 formula, in order?
Start with purchase price. Subtract principal limit. Add HECM fees that are not offset by the principal limit. Subtract earnest money already paid. That cash has to be seasoned, seasoned-gift, or otherwise acceptable funds. Confirm gift overlays with the underwriter. I will not invent a HUD gift-form number.
Principal limit still sits in the mid-30s to low-50s percent of the lesser of price and $1,249,125, depending on age and expected rate. I will not quote a live principal-limit cell on Nia’s Mesa file. Do not interpolate HUD rows. Younger buyers bring more cash. Older buyers bring less. Rates move the factor. Margin plus 10-year CMT, rounded to 0.125%, is the HECM expected rate under 24 CFR 206.3.
Counseling still costs $125–$175. The HUD certificate lasts 180 days. Arizona Mesa files have no 1923.2(k) pause. California Santa Rosa files do. Counsel before the contract is tight.
How do the site’s 7.000% worked examples compare by age on a $750,000 purchase?
As of 22 September 2026, hecm-factors.md uses a 7.000% expected-rate column and a closing-cost stack of 2.00% initial MIP plus origination at the $6,000 cap plus $4,000 third-party — $25,000 on $750,000. Age 62: about $541,000 cash including that stack (72.1% of price). Age 68: about $507,250 (67.6%). Age 75: about $475,000 (63.3%). Age 85: about $391,750 (52.2%). Those are site worksheets, not Nia’s lock. A lower expected rate would raise principal limit and cut cash. A higher rate would do the opposite.
Mortgagee Letter 2017-12 still charges 2.00% initial MIP of claim amount. On $750,000 that is $15,000. On a price at the 2026 cap of $1,249,125 it is $24,982.50, often shown as $24,983. Annual MIP is 0.50% of outstanding balance after closing. Origination is still capped at $6,000 under 24 CFR 206.31.
If residual income requires a LESA, that set-aside is origination-only and can raise cash if it consumes principal limit. Jay confirmed it cannot be added later.
What happens to cash when the price sits above the 2026 cap?
Claim amount stops at $1,249,125. Principal limit will not follow the extra $350,000 on a $1.6 million Mesa listing. Nia brings that extra price as cash, plus unfinanced fees, minus earnest money. Proprietary purchase options, if a channel offers them, are a different worksheet. The proprietary notes Jay originates include HomeSafe, Longbridge Platinum, Finance of America, and Mutual of Omaha Secure Equity. They are not FHA-insured. Compare. I will not promise cheaper.
A second geography: a 62-year-old in Santa Rosa whose California H4P on $750,000 needs about $541,000 including the $25,000 stack at the same 7.000% assumption. Same formula. Seven-day hold after counseling. Same need to occupy on day one.
After funding, an adjustable purchase HECM still accrues at 1-month CMT plus lender margin. Expected rate still rounds to 0.125% under 24 CFR 206.3. Jay still quotes about 30 days on a complete refinance. Purchase cash follows the contract. I will not promise a refinance average.
Heirs who later keep Nia’s Mesa house repay the outstanding loan balance under 24 CFR 206.125(a)(2)(i). A large down payment does not rewrite that subsection into a family discount.
Who should not write an offer before the cash formula is run?
This path does not help a household that wrote a number from a 20% conventional habit. Occupancy is still 24 CFR 206.39. I work with multiple lenders. I will run 24 CFR 206.44 out loud. I will turn away a 20%-should-be-enough plan whose only thesis is a forward-mortgage memory.
If Nia cannot bring the cash the formula produces, skip the listing. The down payment calculation cannot invent funds. It can only show why H4P cash is large, and why age, price, cap, and expected rate each move it.
Does a larger earnest-money deposit reduce HECM for Purchase cash dollar-for-dollar?
Earnest money already paid is subtracted in 24 CFR 206.44. It does not shrink MIP. Nia’s Mesa $10,000 deposit reduces the check at closing by that $10,000 if it is credited correctly. Santa Rosa files follow the same subtraction. A deposit you cannot prove is not a credit. Keep the receipt.
Does seller credit reduce HECM for Purchase cash the way it reduces a forward down payment?
Interested-party credits are limited. 24 CFR 206.44 still has to be satisfied with acceptable funds. Nia should not assume a Mesa seller credit is a HUD blank check. Santa Rosa family sales have extra identity-of-interest issues. Confirm overlays. I will not invent an LTV cap as a site constant.
Run the formula first. Then ask whether a credit is even usable. Occupancy still has to be true on day one.
