What Is a USDA Loan?
A USDA loan is a mortgage issued by a private lender and guaranteed by the U.S. Department of Agriculture through the Guaranteed Loan Program. It is designed to help low- and moderate-income borrowers purchase homes in eligible rural and suburban areas — with no down payment required.
The USDA does not lend money directly through the Guaranteed program. Instead, it backs loans made by approved private lenders. The USDA guarantee reduces lender risk, which enables the program's $0 down terms without requiring private mortgage insurance.
Unlike most loan programs, USDA loans have two eligibility gates: the borrower's household income must be at or below 115% of the area median income (AMI), and the property must be located in a USDA-designated eligible area.
Eligibility Requirements
USDA loan eligibility is determined by two independent requirements — both must be satisfied. Meeting one does not guarantee eligibility if the other is not met.
Total household income — including all adults living in the home, not just those on the loan — must be at or below 115% of the area median income (AMI) for the county.
Income limits vary by household size and location. A household of four in one county may qualify at a higher dollar amount than the same household in a different county.
The property must be located in a USDA-designated eligible area. These are generally rural and suburban communities — many areas outside major urban centers qualify, including some areas that may seem suburban.
Eligible areas are defined by the USDA and updated periodically. A property's eligibility should always be confirmed prior to making an offer.
USDA Loan Features at a Glance
Here's how the key features of the USDA Guaranteed Loan Program break down.
The USDA Guarantee Fee
Instead of traditional mortgage insurance, USDA loans carry a guarantee fee structure: a one-time upfront fee and a smaller ongoing annual fee. Both are lower than FHA's equivalent costs in most scenarios.
Of the loan amount, paid once. Can be financed into the loan — no out-of-pocket payment needed at closing.
Of the remaining loan balance per year, divided into monthly payments. Continues for the life of the loan.
Cost
FHA's upfront MIP is 1.75% and annual MIP typically runs 0.55%–0.85% — meaningfully higher than USDA's 1% / 0.35% structure.
Income Limits
USDA income limits apply to the entire household — not just the borrowers on the loan. All income from adults living in the home is counted, regardless of whether they are on the mortgage.
The USDA sets income limits at 115% of the area median income (AMI) for each county and household size. A household of five in a higher-cost county will have a higher dollar limit than a household of two in a lower-cost county — the percentage threshold is fixed, but the dollar amount varies widely.
Income that counts includes wages, salaries, self-employment income, Social Security, alimony, child support, and other regular income sources from all adults in the household. Certain deductions — such as for dependents and child care — may reduce the countable household income figure.
Property Eligibility
The property must be located in a USDA-designated eligible area and serve as the borrower's primary residence (purchase transactions). Eligible areas include most rural communities and many suburban areas outside major metropolitan centers.
USDA-eligible areas are generally defined as rural communities and smaller towns. However, many areas that feel suburban — particularly those on the outskirts of mid-size cities — are also USDA-eligible. The boundary is determined by USDA maps, not by how an area looks or feels.
The property must be a modest single-family home used as the borrower's primary residence. It must be in good condition and meet USDA minimum property standards. The program is not available for income-producing properties, second homes, or investment properties.
