A USDA loan is a zero-down-payment mortgage for homes in eligible rural and suburban areas, backed by the U.S. Department of Agriculture. Income limits apply (typically 115% of area median income). Many areas around San Antonio qualify. USDA loans offer competitive rates and low guarantee fees (1% upfront + 0.35% annually).
How USDA Loans Work: Zero Down, Income Limits, Eligible Areas
USDA loans are backed by the U.S. Department of Agriculture to encourage homeownership in rural and suburban areas. They offer 100% financing (zero down) and lower mortgage insurance costs than FHA. The catch is that the home must be in a USDA-eligible area and your household income must fall within local limits. The USDA does not lend money directly. It guarantees the loan through approved lenders.
USDA loans come in two types: the USDA Guaranteed Loan (for moderate-income borrowers) and the USDA Direct Loan (for low and very-low-income borrowers directly through the USDA). Most buyers use the Guaranteed Loan, which is available through regular mortgage lenders.

Eligible Areas Near San Antonio
Many areas around San Antonio qualify for USDA loans, including parts of Bulverde, Spring Branch, New Braunfels, Schertz, Cibolo, and smaller towns in the Hill Country. The USDA eligibility map is easy to check online. You simply enter an address to see if the property is in a qualifying area. Many suburban neighborhoods that feel like they are close to the city still qualify.
Income Limits
USDA loans require your household income to be at or below 115% of the area median income for the location of the property. For a 1-4 person household in Bexar County, the 2026 limit is approximately $120,000. For 5-8 person households, the limit is higher. These limits adjust annually and vary by county.
Guarantee Fees: Lower Than FHA MIP
Instead of standard mortgage insurance, USDA charges two guarantee fees: an upfront fee of 1% of the loan amount (can be rolled into the loan) and an annual fee of 0.35% paid monthly. On a $300K loan, the annual fee is about $87 per month. Compare that to FHA's annual MIP of about $138 per month on the same loan. USDA is significantly cheaper for similar loan terms.
How to Apply for a USDA Loan
First, check the USDA eligibility map for the area you want to buy in. Then find a lender that offers USDA loans (not all do). Get pre-approved and find a home in an eligible area. Your lender will handle the USDA approval as part of the loan process. It generally takes 45-60 days from application to closing.
