How charitable capital could help
The gap is the funding requirement
A large gap is not a reason to abandon the mission. It tells donors how much each lasting homeownership outcome costs. The questions are whether that money can be raised, whether support lasts as long as promised, and whether households stay owners.
What already exists
| Provider or program | What it offers | Who it serves | Scale reported |
|---|---|---|---|
| NACA | No down payment, closing costs or mortgage insurance; below-market fixed rate (6.5% APR for priority members on Sep 25, 2026); counseling and membership duties | Priority: income under the metro median, or buying in lower-income tracts; price caps apply | 75,000 mortgages (NACA's figure) |
| Habitat for Humanity | Affordable mortgage, sweat equity, financial education; payment capped at 30% of gross income | Income at or below 60% of area median | 15,952 people served through new and rehab homes, U.S. and Canada, FY2025 |
| State housing finance agencies | Low-cost first-time buyer mortgages funded by mortgage revenue bonds; mortgage credit certificates | Income up to area median (115% for larger families); price limits | About 100,000 families a year historically |
| Down payment assistance programs | Mostly second mortgages (56%) and some grants (9%) for down payment and closing costs | Varies; run by cities (39%), nonprofits (22%), state agencies (18%) | 2,746 programs as of July 1, 2026 |
| Low-down-payment loans | FHA from 3.5% down; Fannie Mae HomeReady and Freddie Mac Home Possible from 3%; VA and USDA from 0% | HomeReady and Home Possible: up to 80% of area median; USDA: rural, up to 115% | National programs |
| Community land trusts and shared equity | Below-market price in exchange for limits on resale price | Usually lower-income buyers | About 44,000 homes, 314 organizations (2022 census, secondary report) |
Where the gap may remain (hypothesis, not yet measured). Most existing help is sized for the down payment and targets incomes at or below the area median. In the worked example, the buyer already has 20% down and still faces a $1,158 monthly gap. Two groups need study: moderate-income workers above program income limits, and eligible buyers whose assistance covers cash at closing but not the monthly payment. How many people fall in either group is not known from this research.
Five ways to fund the gap
All figures use the $500,000 example: a $1,158 monthly gap and a $1,503 earnings-supported payment. Present values are discounted at the 7% mortgage rate.
| Approach | Donor capital per home | Household payment | How long relief lasts | Capital recycled | Main risk |
|---|---|---|---|---|---|
| Upfront principal reduction (grant) | $174,052 | $1,503 for 30 years | Permanent; equity stays with the owner | No, unless resale recapture is added | Highest cost per home; subsidy can leak into price where supply is tight |
| Permanent rate buydown to 2.12% | Up to $174,052 | $1,503 while the loan lasts | Ends at sale or refinance; worth $99,732 if the loan ends in year 10 | No | Market pricing for buydowns this deep is unverified; points count toward federal fee caps (3% for loans of $137,958+) |
| Time-limited monthly subsidy, 5 years | $69,478 | $1,503, then $2,661 | 5 years, then a payment cliff | No | Payment share jumps from 27.7% to 39.6% of median earnings when support stops |
| Declining subsidy until earnings catch up | $101,925 | Held at 27.7% of earnings | 13.3 years if earnings grow 4.38% a year | No | Household and donor both depend on income growth; funds must be reserved up front |
| Recoverable deferred second lien (0%) | $174,052 | $1,503 for 30 years | Until sale, refinance or maturity | Yes, nominal; worth $136,083 today if repaid in year 10 | Household still owes $400,000 in total; losses if prices fall |
Shared-appreciation versions of the recoverable lien repay a share of any price gain, which protects the real value of recycled capital but reduces the owner's equity. A permanent buydown held for all 30 years costs the same in present value as a principal reduction; it is cheaper only because relief ends earlier. Fannie Mae rules allow 501(c)(3) grants and "Community Seconds" subordinate loans, and exclude payments deferred at least five years from debt-to-income ratios (B3-4.3-06, B5-5.1-02).
What happens when support ends
Principal reduction or deferred second lien
Flat monthly subsidy for 5 years
Declining subsidy until earnings catch up
Principal and interest as a share of median full-time earnings, starting from Q2 2026 earnings and assuming they grow 4.38% a year (the 2020–2026 median pace) with the rate fixed at 7%. Individual earnings, not household income; an actual household's path could be faster or slower.
Relief now versus debt owed
A grant and a deferred second lien give the same monthly relief. They leave the household with very different balance sheets.
Would the subsidy just raise prices?
It depends on supply. England's Help to Buy raised new-build prices about 8% inside Greater London with no detectable extra building, while near the Welsh border it added construction with little price effect. A U.S. study of the mortgage interest deduction found the same pattern: where regulation limits building, prices absorb buyer subsidies.
A small pilot is unlikely to move a market, but concentrated assistance can be captured in negotiation. Market choice, purchase-price limits and tracking prices paid against appraisals are ways to test for leakage.
Funding scenarios in both directions
What a pilot should establish
The pilot's purpose is to learn what lasting ownership costs and whether it holds, not to avoid the size of the gap. These are proposals for the founders to decide.
- Fund every household's full commitment before the first closing, including all future monthly support.
- Compare at least two structures, such as an upfront principal reduction and a recoverable shared-appreciation lien, against similar applicants who did not receive help where that is feasible.
- Choose markets partly on how readily housing supply responds, and track prices paid.
- Work through existing counseling agencies, housing finance agencies and mission lenders rather than rebuilding them.
- Publish aggregate results with independent review. Never publish recipients' personal information.
What counts as success
| Sustained ownership | Still owners at 1, 3 and 5 years; exits by choice versus distress |
|---|---|
| Affordability | Housing cost share of household income at closing and each year after |
| Financial resilience | Emergency savings, 30/60/90-day delinquency, forbearance use |
| Donor impact | Dollars per household-year of affordable ownership; capital recovered |
| Market effects | Price paid versus appraisal; local price trend |
Closings completed is an activity count, not an outcome.
