What Is a USDA Loan? Zero-Down Mortgages for Rural Buyers

USDA loans offer one of the most affordable paths to homeownership in the United States — zero down payment, low mortgage insurance, and competitive interest rates. The catch is that both the property and the borrower must meet specific eligibility requirements. Here is everything you need to know about USDA loans and whether you qualify.

To estimate your monthly payment with no down payment, use our mortgage payment calculator. If you are comparing loan options, our debt-to-income calculator can help you determine how much house you can afford under USDA guidelines.

USDA Loan Definition

A USDA loan is a mortgage backed by the U.S. Department of Agriculture through its Rural Development program. The program’s official name is the Section 502 Guaranteed Loan Program, and its goal is to help low-to-moderate-income borrowers purchase homes in rural and suburban communities across the country.

Like VA and FHA loans, the USDA does not lend money directly in the guaranteed loan program. It provides a guarantee to approved private lenders, reducing their risk and allowing them to offer favorable terms — including zero down payment — to eligible borrowers.

Eligible Areas

USDA eligibility is tied to location. The property must be in an area designated as rural or suburban by the USDA. Despite the name, eligible areas extend well beyond farms and countryside. Many suburban communities, small towns, and outlying areas near larger cities qualify.

As a general rule, areas with populations of 35,000 or fewer are typically eligible, though many areas with populations up to 20,000 are automatically included. Some communities retain their eligibility even as they grow, through grandfathering provisions.

The USDA provides an online eligibility map where you can enter a specific address and instantly see whether the property qualifies. Checking property eligibility should be one of the first steps in your home search if you are considering a USDA loan.

Income Limits

USDA loans are designed for low-to-moderate-income households. Your household income cannot exceed 115% of the area median income (AMI) for the county where the home is located. This includes income from all adults in the household, not just the borrowers on the loan.

Income limits vary significantly by county and household size. For a family of four in many areas, the limit might be $110,000 to $130,000 per year, while in higher-cost areas it can exceed $150,000. The USDA provides an income eligibility tool on its website where you can check the limits for your specific county and household size.

Certain deductions are allowed when calculating household income, including childcare expenses for children under age 12, disability-related expenses, and deductions for elderly household members. These deductions can bring your adjusted income below the limit even if your gross income appears to exceed it.

Zero Down Payment

Like VA loans, USDA loans require no down payment. You can finance 100% of the home’s appraised value. This makes USDA loans one of only two major mortgage programs that allow zero-down financing (the other being VA loans for eligible military borrowers).

If the appraised value exceeds the purchase price, you may be able to finance closing costs into the loan up to the appraised value. This can further reduce the cash you need at closing.

USDA Guarantee Fee

While USDA loans do not have traditional private mortgage insurance, they do charge a guarantee fee that serves a similar purpose:

  • Upfront guarantee fee — 1.0% of the loan amount, paid at closing. This can be rolled into the loan balance.
  • Annual guarantee fee — 0.35% of the outstanding loan balance, paid monthly as part of your mortgage payment.

The annual fee of 0.35% is significantly lower than FHA’s annual MIP of 0.55% and lower than most conventional PMI rates. On a $250,000 loan, the annual USDA guarantee fee works out to about $73 per month in the first year, compared to roughly $115 per month for FHA MIP on the same loan amount.

The annual guarantee fee remains for the life of the USDA loan. To eliminate it, you would need to refinance into a conventional loan once you have enough equity.

USDA Loan Requirements

Credit Score

The USDA does not set a hard minimum credit score, but most lenders require a 640 or higher for automated underwriting approval through the USDA’s GUS (Guaranteed Underwriting System). Borrowers with scores below 640 may still qualify through manual underwriting, though this requires stronger compensating factors and more documentation.

Debt-to-Income Ratio

USDA guidelines set the standard DTI limits at 29% front-end (housing costs) and 41% back-end (total monthly debts). With compensating factors — like a high credit score, significant savings, or a minimal increase in housing payment — these limits can be exceeded. Check where you stand with our debt-to-income calculator.

Property Requirements

The home must be a single-family residence (including eligible condos, townhomes, and manufactured homes on permanent foundations) located in a USDA-eligible area. It must be your primary residence — USDA loans cannot be used for investment properties, vacation homes, or income-producing farms. The home must be modest for the area, meaning it cannot have features considered luxurious, such as an in-ground swimming pool in some markets.

Citizenship and Residency

Borrowers must be U.S. citizens, U.S. non-citizen nationals, or qualified aliens. Permanent resident aliens with a valid green card are eligible.

USDA vs. FHA vs. VA Comparison

All three are government-backed loan programs, but they serve different audiences:

  • Down payment — USDA and VA require zero. FHA requires 3.5%.
  • Mortgage insurance — USDA charges 0.35% annually (lowest). FHA charges 0.55% annually. VA has no annual mortgage insurance.
  • Upfront fee — USDA charges 1.0%. FHA charges 1.75%. VA charges 1.25% to 3.3%.
  • Location restrictions — USDA is limited to eligible rural and suburban areas. FHA and VA have no location restrictions.
  • Income limits — USDA has income caps (115% of area median). FHA and VA have no income limits.
  • Eligibility — USDA is open to all qualifying borrowers. VA requires military service. FHA is open to all qualifying borrowers.
  • Credit score — USDA typically needs 640. FHA allows 580 (or 500 with 10% down). VA has no official minimum but lenders usually require 620.

Pros and Cons of USDA Loans

Advantages

  • Zero down payment makes homeownership accessible without years of saving.
  • Lowest annual mortgage insurance of any government loan program (0.35%).
  • Competitive interest rates — often comparable to or lower than FHA rates.
  • Closing costs can potentially be financed if the appraisal exceeds the purchase price.
  • No maximum loan amount — limited only by your income and the area’s home prices.

Disadvantages

  • Geographic restrictions limit where you can buy.
  • Income limits may disqualify households with moderate-to-high earnings.
  • Guarantee fee lasts the life of the loan.
  • Processing times can be longer than conventional or FHA loans because USDA must review and approve each loan in addition to the lender’s underwriting.
  • Primary residence only — no investment or vacation properties.

How Long Does USDA Loan Approval Take?

USDA loans typically take 30 to 60 days from application to closing, which is slightly longer than conventional loans (30 to 45 days). The extra time is due to the dual-approval process: your lender underwrites the loan first, then submits it to USDA for a second review and final approval. During busy periods, the USDA review can add one to two weeks to the timeline. For more on the underwriting process, see our guide on how long underwriting takes.

Frequently Asked Questions

What areas qualify for a USDA loan?

USDA-eligible areas include rural communities and many suburban areas with populations of 35,000 or fewer. The definition is broader than most people expect — many areas just outside city limits, small towns, and outlying suburbs qualify. The USDA provides an online eligibility map where you can enter any address and instantly see whether it falls in an eligible zone.

What are USDA income limits?

Your household income cannot exceed 115% of the area median income for the county where the home is located. Limits vary by county and household size. For a typical family of four, limits range from roughly $110,000 to over $150,000 depending on the area. The USDA provides an online tool to check limits for your specific county and household size, and certain deductions (childcare, disability expenses) can lower your calculated income.

Is there mortgage insurance on a USDA loan?

USDA loans do not have traditional private mortgage insurance, but they charge a guarantee fee that serves a similar purpose. There is a 1.0% upfront fee (which can be financed into the loan) and a 0.35% annual fee paid monthly. The annual rate of 0.35% is the lowest among all government-backed loan programs — lower than FHA’s 0.55% and significantly less than most conventional PMI rates.

Can I buy a home in the suburbs with a USDA loan?

Yes, in many cases. While USDA loans are designed for rural areas, the eligibility map includes many suburban communities, especially those on the outskirts of metropolitan areas. Areas that were once rural but have seen moderate growth may still be eligible through grandfathering provisions. The best approach is to check specific addresses on the USDA eligibility map before making an offer.

How long does a USDA loan take to close?

USDA loans typically take 30 to 60 days from application to closing. The timeline is slightly longer than conventional loans because USDA requires a separate approval step after your lender completes underwriting. During peak periods, the USDA review alone can take one to two weeks. Working with a lender experienced in USDA loans and having all your documents ready upfront can help minimize delays.
