Quick Answer
The HECM for Purchase down payment equals the purchase price minus the available HECM principal limit — with the principal limit calculated using the lesser of the appraised value or purchase price, the borrower's age, and current interest rates — typically requiring 40% to 60% of the purchase price.
- Down payment = purchase price minus HECM principal limit.
- PLF is calculated on the lesser of appraised value or purchase price.
- At age 65: approximately 48-55% PLF — down payment approximately 45-52% of price.
- At age 75: approximately 55-62% PLF — down payment approximately 38-45% of price.
- At age 85: approximately 62-70% PLF — down payment approximately 30-38% of price.
- Older buyers need smaller down payments because the PLF is higher.

Detailed Explanation
The HECM for Purchase down payment is determined by the same principal limit factor tables used for standard HECM refinances — applied to the lesser of the appraised value or the purchase price. The buyer is not funding the gap between the home's full value and some arbitrary down payment percentage; they are funding the gap between the full purchase price and the HECM's maximum financing capacity at the buyer's age.
For a 70-year-old buyer purchasing a $600,000 California home with a PLF of approximately 52%, the calculation is: $600,000 × 52% = $312,000 in HECM financing. The down payment is $600,000 − $312,000 = $288,000. The buyer brings $288,000 to closing (plus $18,000 to $24,000 in closing costs), the HECM finances $312,000, and the seller receives the full $600,000.
The age effect on the down payment requirement is significant and creates a specific planning consideration: a buyer who purchases at 70 requires a larger down payment than the same buyer at 80. This means that timing the H4P purchase — waiting until a spouse is older, or waiting for a birthday that moves into a higher PLF table — can meaningfully reduce the required down payment. A one-year delay in purchase at age 70 might reduce the required down payment by $10,000 to $20,000 on a $600,000 home.
Down payment sources for the H4P are restricted to the buyer's own assets — the HECM cannot be stacked with another mortgage to make up the down payment. Acceptable sources include: net proceeds from selling a prior home, savings and investment accounts, 401(k) or IRA withdrawals (subject to tax implications), gifts from family members (with gift documentation), and bridge financing. The down payment cannot come from the seller, from the lender, or from any arrangement that effectively reduces the buyer's equity contribution.
Jay Zayer, CRMP — 18 Years Experience
The down payment question is the first thing I model in every HECM for Purchase consultation. I run the age through the PLF table, apply it to the target purchase price, and present the down payment number clearly: here is how much you need to bring to the closing table, here is how much the HECM finances, and here is how much closing costs add to your total upfront cash. When clients see that at age 78 they might only need to put 38% down on their new home with no monthly payment, the H4P often becomes an obvious choice.
Who This Is Right For
This may be a good fit if:
- You are evaluating the HECM for Purchase and want to know exactly how much you need to bring to closing
- You want to model how your age affects the down payment requirement on different purchase prices
This may NOT be the right fit if:
- Your available down payment funds are insufficient for the required H4P amount at your age — consider whether waiting a few years or purchasing at a lower price changes the calculation
Common Misconception
Myth: The HECM for Purchase requires the same 3.5% down as an FHA forward loan.
Fact: The H4P down payment is typically 40% to 60% of the purchase price — far more than an FHA forward mortgage because the HECM's principal limit is a smaller percentage of the home's value than a forward mortgage loan-to-value.

People Also Ask
How does my age affect the HECM for Purchase down payment?
The older you are, the higher the PLF and the less down payment you need. Each year of additional age increases the PLF by approximately 0.5% to 1.0% of the home's value.
Can family members help with the H4P down payment?
Yes — documented gifts from family members are an acceptable down payment source. A gift letter and documentation of the fund transfer are required.
What happens if the appraisal comes in lower than the purchase price?
The HECM is calculated on the lesser of the appraised value or purchase price. A low appraisal increases your required down payment — you fund the gap between the purchase price and the lower appraised value.
