Buying a home with a reverse mortgage in South Dakota is an option a growing number of retirees are considering when they want to right-size, relocate, or move into a home better suited to aging in place. The product is officially called HECM for Purchase, and it lets you combine a down payment with a federally insured reverse mortgage to buy your next primary residence, with no monthly principal and interest payment going forward. It is a different conversation than a traditional mortgage and worth understanding before your next move.
Our team at the Heartland Branch works with retirees across Sioux Falls, Rapid City, Brookings, Watertown, Harrisburg, and smaller South Dakota communities who are weighing this path. This guide walks through how HECM for Purchase works, the down payment math by age, who it is designed for, and how it compares to a traditional mortgage. For the broader picture, see our complete guide to reverse mortgages in South Dakota.
Step 1: Understand What HECM for Purchase Is
HECM for Purchase is a federally insured reverse mortgage product designed specifically for buying a primary residence. It was introduced by HUD in 2008 so retirees could use reverse mortgage proceeds to buy a new home, not only to tap equity in an existing home.
The mechanics are simple at a high level. You make a sizable down payment, typically 40% to 60% of the purchase price depending on your age, and the HECM covers the rest of the purchase. You make no monthly principal and interest payment on the reverse mortgage for as long as the home remains your primary residence. You still pay property taxes, homeowner’s insurance, HOA dues if applicable, and basic maintenance, as you would with any home you own.
Why it matters: For retirees who want to move but do not want a monthly mortgage payment pulling from retirement income, HECM for Purchase is one of the few products built specifically for that goal.
Step 2: Buying a Home with a Reverse Mortgage in South Dakota: How the Numbers Work
The down payment required for a HECM for Purchase is essentially the flip side of the principal limit. The older you are, the higher the principal limit available, which means a smaller required down payment for the same home. Here is an illustrative table showing typical down payment requirements on a $325,000 South Dakota home at various ages.
| Buyer Age | Approximate Down Payment | HECM for Purchase Covers |
|---|---|---|
| 62 | ~$195,000 – $210,000 (60-65%) | ~$115,000 – $130,000 |
| 70 | ~$165,000 – $175,000 (50-54%) | ~$150,000 – $160,000 |
| 78 | ~$140,000 – $150,000 (43-46%) | ~$175,000 – $185,000 |
| 85 | ~$120,000 – $130,000 (37-40%) | ~$195,000 – $205,000 |
These figures are illustrative and will move with interest rates, but the pattern holds: older buyers qualify for a larger HECM, which translates into a smaller required down payment for the same home. Our team can run exact numbers for your age and target home.
Step 3: Who HECM for Purchase Is Designed For in South Dakota
Retirees right-sizing. Couples who want to move from a larger family home to a single-level townhome or smaller property. You use part of the sale proceeds from the old home for the HECM down payment and keep the rest for retirement, all without taking on a new monthly payment.
Relocating retirees. Families moving to be closer to children and grandchildren, often purchasing a home in Sioux Falls, Rapid City, Harrisburg, or a smaller South Dakota community that is new to them.
Aging-in-place buyers. Retirees specifically shopping for homes designed for long-term livability: single-story layouts, wider doorways, accessible bathrooms, and low-maintenance yards. Removing the monthly mortgage payment keeps retirement income free for healthcare and lifestyle costs.
Cash buyers who want liquidity. Some retirees planning to pay all cash for a home instead use HECM for Purchase to keep a meaningful portion of their savings invested and liquid while still having no monthly payment.
Step 4: Where Your Down Payment Can Come From
HUD is specific about acceptable sources of funds for the HECM for Purchase down payment. Allowed sources include sale proceeds from your previous home, personal savings, retirement account withdrawals, gift funds from a family member (with a gift letter), and proceeds from the sale of other assets. The key documentation requirement is that the source of funds must be fully traceable and seasoned in a verified account.
The most common source for South Dakota buyers is the sale of the previous home. If your current home is selling for $450,000 and your HECM for Purchase on a $325,000 home requires a $175,000 down payment at age 70, you would use $175,000 of the sale proceeds and keep the remaining $275,000 (minus selling costs) to support retirement.
What is not allowed: borrowed funds from a personal loan, a credit card, or a HELOC on another property. The program requires that your down payment represent real equity rather than additional debt.
Step 5: Eligibility Requirements
Eligibility for HECM for Purchase mirrors standard HECM eligibility with a few purchase-specific details.
Age. All borrowers on title must be 62 or older.
Occupancy. You must occupy the home as your primary residence within 60 days of closing. Second homes and investment properties are not eligible.
Property type. Single-family homes, 2-to-4 unit properties (you occupy one unit), FHA-approved condominiums, and manufactured homes that meet HUD standards and sit on land you own. Co-ops and most mobile homes on leased land are not eligible.
Construction status. The home must be fully completed with a certificate of occupancy before closing. HUD does not allow HECM for Purchase on a home still under construction, though you can close after the build is finished if you are buying new construction.
Counseling. HUD-approved reverse mortgage counseling is required before application, just as with any HECM. For a deeper look at qualification, see our article on whether you qualify for a reverse mortgage in South Dakota.
Step 6: HECM for Purchase Compared to a Traditional Mortgage
| Feature | HECM for Purchase | Traditional Mortgage |
|---|---|---|
| Monthly P&I Payment | None required | Required throughout loan term |
| Typical Down Payment | 40% to 60% (age-based) | 5% to 20% typical |
| Qualification Focus | Age, equity, financial assessment | Income, credit, DTI |
| Upfront Costs | Higher (origination + MIP) | Lower |
| Balance Over Time | Grows (interest accrues) | Shrinks with each payment |
| Loan Becomes Due When | You permanently leave the home | End of amortization period |
The trade-off is direct. HECM for Purchase requires more cash upfront but removes the monthly payment for as long as you live in the home. For retirees with meaningful home sale proceeds or savings and a plan to stay in the new home for 10 or more years, the math often works in favor of HECM for Purchase.

Step 7: The HECM for Purchase Process, Step by Step
Pre-qualification. Our team runs your age and target home price to estimate your required down payment and HECM for Purchase principal limit. This takes a day or two.
Counseling. Complete a session with a HUD-approved reverse mortgage counselor. You will receive a certificate valid for 180 days that must be in hand before formal application.
Home search. Work with your realtor as you would on any purchase. Make sure the property type is HECM-eligible. Condos need to be on the FHA-approved list; manufactured homes need to meet HUD standards.
Offer and application. When you have a home under contract, submit the formal HECM for Purchase application with full documentation of your down payment source.
Appraisal and underwriting. The FHA appraisal will verify the property meets HUD standards. Underwriting typically takes 30 to 45 days from application to clear-to-close.
Close and move in. Close on the purchase and occupy the home as your primary residence within 60 days.
Step 8: When HECM for Purchase Is Not a Good Fit
A few scenarios where a traditional mortgage (or paying cash) makes more sense than HECM for Purchase.
Short time horizon. If you expect to sell within 3 to 5 years, the higher upfront costs of HECM for Purchase dominate. A traditional mortgage or cash purchase is often cleaner.
Insufficient down payment. If you cannot come up with the 40% to 60% required, a traditional mortgage with 10% to 20% down may be the only option, assuming you qualify on income and credit.
Comfortable with a monthly payment. If your retirement income handles a monthly mortgage payment without strain and you prefer a shrinking balance rather than a growing one, a traditional mortgage may suit you better.
Preference for a HELOC approach. Some buyers consider keeping their existing home, using a HELOC for flexibility, rather than moving. Our companion article on reverse mortgage vs. HELOC in South Dakota walks through those alternatives.
