Two government-backed mortgages dominate the conversation for buyers who don’t have 20% down saved. The USDA loan and the FHA loan both promise low or no down payments, forgiving credit standards, and the full faith of Uncle Sam standing behind them. The differences matter more than most side-by-side comparison charts admit, and they often come down to something as simple as the address of the house you want to buy.
Where the House Sits Settles Half the Argument
The USDA loan exists to keep rural housing affordable. The FHA loan exists to help borrowers with thin credit files or small savings buy almost anywhere. That mission gap shapes everything else.
Eligibility for the USDA’s guaranteed program depends on the property’s location, not your job. About 97% of U.S. land mass qualifies, but only around 30% of the population actually lives in those areas. The agency publishes an eligibility map you can check in fifteen seconds: type in an address and you get a yes or a no. Suburbs on the outer edge of a metro area are frequently eligible. A house inside city limits usually isn’t.
FHA carries no geographic restriction. Downtown Chicago, a Houston suburb, a town of 800 people in Nebraska. All fair game, as long as the property meets HUD’s minimum standards and you plan to live in it. That single factor eliminates one of the two options for a lot of buyers before down payments even come up.
Down Payment and Credit Score Requirements
USDA guaranteed loans
- 0% down. The full purchase price can be financed.
- 640 credit score for automated approval. Scores between 620 and 639 can still go through manual underwriting with compensating factors like low debt or healthy cash reserves.
- No score at all is possible when you can document a clean 12-month record of rent, utility, and insurance payments.
- Debt-to-income ratio generally capped near 29% for housing costs and 41% across all debts.
FHA loans
- 3.5% down with a 580 or better score. On a $250,000 house, that’s $8,750 out of pocket.
- Scores between 500 and 579 require 10% down.
- Debt-to-income ratios stretch past 50% with automated approval, though 43% is the common ceiling.
- Gift funds, down payment assistance grants, and seller-paid closing costs are widely accepted.
Mortgage Insurance Is Where the Real Money Hides
Neither loan is free, and the insurance structure is the largest long-term difference between them.
USDA guaranteed loans charge a 1% upfront guarantee fee, which gets rolled into the loan balance, plus an annual fee of 0.35% on the outstanding amount. That annual fee sticks around for the life of the loan unless you refinance out of it.
FHA charges a 1.75% upfront mortgage insurance premium plus annual MIP of 0.55% on most 30-year loans. Here’s the sting: if your down payment is below 10%, that MIP never goes away. Not at 20% equity, not at 50%. Only a refinance removes it.
Run a $250,000 purchase through both programs and the gap shows up fast:
- USDA: $252,500 loan once the guarantee fee is financed. Annual fee runs about $73 a month. Nothing down.
- FHA: $8,750 down plus a $245,472 loan after upfront MIP. Annual MIP runs about $110 a month.
USDA comes out roughly $37 a month cheaper on insurance and asks for $8,750 less at closing. Over ten years, that’s about $4,400 in insurance savings alone, on top of the cash you never had to bring to the table.
Closing Costs and Seller Concessions
Both programs let the seller contribute up to 6% of the purchase price toward your closing costs, which matters a great deal when your down payment is zero. Typical closing costs land between 2% and 5% of the loan amount, so budget $5,000 to $12,500 on a $250,000 purchase. USDA permits the 1% guarantee fee to be financed, and FHA permits the 1.75% upfront premium to be financed. Either way, that money doesn’t have to come out of your bank account on closing day.
Income Limits and Loan Size
USDA guaranteed loans come with a household income cap, generally 115% of the area median income for your county and family size. A family of four in a county with a $70,000 median could earn up to roughly $80,500. Cross that line and the loan is off the table. There’s no set maximum loan amount, but you can’t borrow more than the appraised value, and the home has to be modest for the area.
FHA has no income limit whatsoever. Loan limits vary by county, running from a floor of $524,225 to a ceiling of $1,209,750 in the priciest markets for 2025. That ceiling is why FHA stays viable in places like San Francisco or Fairfield County.
Property Condition Rules Trip People Up
USDA guaranteed loans require the appraisal to confirm the home is safe, sound, and sanitary, and the agency adds its own inspection step on top. Peeling paint, a failing roof, exposed wiring, or a broken window can stall closing until repairs are finished. In-ground pools with diving boards are a problem for the direct program and sometimes for guaranteed loans too.
FHA is comparably strict about health and safety issues in its appraisal, but it carries one real advantage: the FHA 203(k) loan lets you finance a fixer-upper and the renovation in a single mortgage. USDA has no equivalent product.
Both Loans Are Assumable, Which Buyers Underrate
If you might sell within a few years, assumability is worth thinking about. FHA loans closed after December 1986 can be taken over by a new buyer who qualifies, and USDA guaranteed loans can be assumed with lender approval. In a market with 7% rates, handing a buyer your 4% mortgage is a genuine selling point that a conventional loan can’t match.
Matching the Loan to Your Situation
- Buying a $180,000 fixer-upper inside city limits: FHA, potentially with a 203(k) to fund the repairs.
- Move-in-ready ranch 20 minutes outside a small city, household income $68,000, savings you’d rather keep: USDA wins without much debate.
- Credit score of 540 with 15% down in the bank: FHA. USDA would need manual underwriting and a strong alternative credit story.
- Household income of $140,000 in a moderate-cost county: USDA is almost certainly out on income. FHA or conventional.
- Planning to sell in four years with a 4% rate: both are assumable, so take whichever costs less today.
What to Do Before You Pick a Lender
Check the USDA eligibility map with the exact address first. That one step settles the question for many buyers. Then get quotes from a lender who originates both loan types, because a loan officer who only sells FHA will find reasons USDA won’t work.
Ask for a five-year cost projection rather than a single monthly payment. Include the annual fee or MIP, estimated property taxes, homeowners insurance, and the cash you need at closing. Then ask what it takes to refinance into a conventional loan once you reach 20% equity, since that’s the exit door from both government insurance programs.
One more detail worth checking: USDA’s direct program targets very-low and low-income households and offers subsidized rates as low as 1%, but it comes with tighter income caps, longer processing times, and limited annual funding. If your income sits near the line, a call to a USDA Rural Development office is worth the ten minutes before you assume the guaranteed program is your only route.
