USDA Guaranteed loans carry a household income limit set at 115% of the Area Median Income for the county. This is one of the most misunderstood eligibility criteria in residential mortgage because it applies to all household members, not just the borrowers on the loan.
Who Is Counted in Household Income
USDA counts the income of ALL people who will live in the property, including non-borrowers. A borrower's 19-year-old child with a part-time job who will live in the house adds their income to the calculation even if they are not on the mortgage. The only exception: full-time students earning income may be excluded up to a defined threshold in the USDA income eligibility guidelines.
Annual Income vs. Qualifying Income
USDA distinguishes between annual household income (for eligibility) and qualifying income (for debt-to-income ratio). The annual income test is broader -- it includes sources like Social Security, child support, and certain allowances that may not count for DTI. A borrower can pass DTI and fail household income, or vice versa.
Common Calculation Errors
- ✦Counting only borrower income and ignoring co-residents who earn income.
- ✦Excluding Social Security or pension income from the annual calculation.
- ✦Using monthly income when USDA uses an annualized figure for the household test.
- ✦Failing to apply the deductions USDA allows (dependent deduction, disability care deduction, child care deduction) that can reduce counted household income.
Income Limits by County
Income limits vary substantially by county and by household size (1-4 persons vs. 5-8 persons). The USDA eligibility site provides current limits by state and county. Always pull the limit at the time of application -- limits are adjusted annually.
