Buried inside USDA Rural Development is what may be the cheapest home repair money in the country: loans at 1% interest for twenty years, and outright grants that never have to be repaid. The Section 504 program is small, income-restricted, and largely unknown, but for the households who qualify, nothing else comes close on terms.
Here is exactly what it offers and who can get it.
What Section 504 provides
The program has two components, and most applicants receive one or a combination of both.
Repair loans go up to $40,000, at a fixed 1% interest rate, amortized over 20 years. That is not a typo — one percent, at a time when 30-year mortgage rates sit around 6.65%.
Repair grants go up to $10,000 as a lifetime maximum, and are restricted to homeowners aged 62 or older. Grants do not have to be repaid, with one condition: if you sell the property within three years of signing the grant agreement, the full grant becomes repayable.
A loan and grant can be combined up to $50,000 total. In presidentially declared disaster areas the grant maximum rises to $15,000 and the combined cap to $55,000.
One important framing point: this is for existing homeowners, not buyers. You cannot use Section 504 to purchase a home. If you are shopping for a house that needs work, you want a renovation mortgage instead.
Who qualifies
The eligibility screen is genuinely narrow, which is why the program is underused rather than oversubscribed.
- You must own and occupy the home as your primary residence.
- The property must be in an area USDA classifies as rural — check the eligibility map, which covers more territory than most people expect, including many small towns.
- Your adjusted household income must fall at or below the very low income limit for your county, which in practice generally means at or below 50% of area median income. Household size matters. Note that merely “low income” is not sufficient — the program is restricted to the very-low-income tier.
- You must be unable to obtain affordable credit elsewhere.
- For grant funds specifically, at least one qualified applicant must be 62 or older.
What the money can be used for
The loan and the grant have different permitted uses, and this catches people out.
Loan funds are flexible: repair, improve, or modernize the home, or remove health and safety hazards. Eligible costs include equipment, site improvements, storm shelters, retaining walls, and foundation work for manufactured homes.
Grant funds are much narrower. They may only be used to remove identified health and safety hazards, or to repair or remodel the home to make it accessible for a household member with a disability — ramps, grab bars, widened doorways, walk-in tubs. Grants cannot pay for cosmetic upgrades or general modernization.
If USDA determines you can afford to repay part of the cost, expect a combination loan and grant rather than a full grant.
How to apply
Applications are accepted year-round, subject to funding availability, and go directly through your local USDA Rural Development office. There is no lender network to shop — USDA is the lender.
Processing is not fast, and funding is limited, so apply early if you have a repair need that is not an emergency. If the need is an emergency — an unheated home in winter, a collapsing roof — say so, and also contact your county or city housing department, your Area Agency on Aging, and your state Housing Finance Agency in parallel, since local emergency repair programs often move faster.
Worth knowing: the dollar caps are not permanently fixed. Federal regulation ties the loan maximum to 20% of the national average area loan limit and the grant maximum to 10% of the same figure, which is why the caps have risen over the years. Confirm current figures when you apply.
Rolling repairs into a USDA home purchase
If you are buying rather than repairing, USDA has a separate and genuinely useful mechanism. The Section 502 Guaranteed loan allows a “purchase with rehabilitation and repair” structure:
- Up to $35,000 in non-structural repairs can be financed, with no minimum and no qualified-inspector requirement.
- Structural repairs above $35,000 are permitted but require a qualified inspector, a written work write-up, and interim and final inspections.
- The loan is based on 100% of the “as-improved” appraised value — so like other renovation mortgages, the work is financed against what the home will be worth when finished.
- A contingency reserve of 10% is standard, rising to 15% if utilities are off.
- Up to six months of mortgage payments can be financed when the home is not habitable at closing.
Eligible work includes kitchen and bath upgrades, energy-conservation improvements, septic systems, wells, and accessibility modifications. Pools, hot tubs, saunas, and other luxury features are excluded, as are investment properties. Manufactured homes and condominiums are not eligible for the rehabilitation product.
USDA also has a Section 502 Direct loan program where USDA lends directly. The note rate is 5.25% as of August 2026, but payment assistance subsidies can reduce the effective rate to as low as 1% depending on income, with terms up to 33 years, or 38 for very-low-income applicants who cannot afford the shorter payment. Direct loan funds may be used to build, repair, renovate, or relocate a home.
How it compares
For an eligible rural homeowner, Section 504 is simply the best terms available. One percent over twenty years is far below a home equity loan (averaging around 8.1% to 8.3%) and dramatically below a personal loan (averaging over 12%). A grant is better still.
The constraint is eligibility, not desirability. If your income is above the very-low-income limit, or your home is not in an eligible rural area, or you are buying rather than repairing, you will need a different tool — most likely an FHA 203(k), a HomeStyle or CHOICERenovation loan, or, if you have equity, a home equity loan.
Frequently asked questions
How much can I get from USDA Section 504?
Loans go up to $40,000 at 1% fixed for 20 years. Grants go up to $10,000 lifetime for homeowners 62 and older. Combined, the cap is $50,000 — rising to a $15,000 grant and $55,000 combined in presidentially declared disaster areas.
Do I have to repay a USDA repair grant?
Not normally. The one exception is if you sell the home within three years of signing the grant agreement, in which case the full grant amount must be repaid.
What income do I need to qualify?
Your adjusted household income must be at or below the very low income limit for your county — generally around 50% of area median income, varying by household size. Applicants in the merely “low income” tier are not eligible for Section 504.
Can I use Section 504 to buy a home?
No. Section 504 is only for homeowners repairing a home they already own and occupy. To buy a home that needs work in a rural area, look at the USDA Section 502 Guaranteed loan’s purchase-with-rehabilitation option, which can finance up to $35,000 in non-structural repairs.
What can grant money actually pay for?
Only removing identified health and safety hazards, or making the home accessible for a household member with a disability. General remodeling and cosmetic improvements have to be covered by loan funds instead.
