How Does VA Residual Income Work?

Conventional and FHA loans rely primarily on debt-to-income ratio (DTI) to assess repayment ability. VA uses residual income as an additional layer because it measures actual purchasing power, what remains for food, transportation, healthcare, and discretionary spending after obligations are met. A veteran with a 50% DTI might still have strong residual income if their income is high enough, which is why VA loans can approve borrowers that conventional guidelines would reject.

VA calculates residual income by taking gross monthly income and subtracting: the proposed total mortgage payment (PITI), all monthly installment debt payments, revolving debt minimums, child care expenses, state income taxes, and federal income taxes. The remaining figure is compared to the VA's regional table. If the residual income meets or exceeds the minimum for the region and family size, the loan passes this test.

The VA divides the country into four regions (Northeast, Midwest, South, West) and sets different minimums based on loan amount and family size. California falls in the West region. For a family of four with a loan amount over $80,000, the West region minimum residual income is $1,117 per month. Larger families have higher minimums. Smaller loan amounts have slightly lower thresholds. These figures have not changed significantly since the program's early years, which actually makes them fairly easy to meet with today's income levels.

If residual income falls below the VA table minimum, the loan isn't automatically declined, but the underwriter takes a harder look at compensating factors: substantial liquid assets, minimal consumer debt, strong credit history, evidence of long-term employment. A residual income shortfall of 5% or less can often be overcome with documented compensating factors. A significant shortfall, however, is a real qualification obstacle regardless of DTI.
