VA Loan Residual Income: What It Takes to Qualify in Houston

A veteran’s VA loan doesn’t live or die on debt-to-income ratio alone. The VA runs a second test called residual income, the cash left over each month after the mortgage payment, taxes, insurance, debts, and a cost-of-living estimate come out of gross pay. For a family of four in Texas, which the VA groups into its South region, the current minimum is $1,003 a month on loans of $80,000 or more. A veteran can carry a debt-to-income ratio that would sink a conventional loan and still close, as long as the residual income number holds up.

Most first-time VA buyers have never heard the phrase until a loan officer brings it up mid-file, usually right after asking for one more pay stub.

We walk veteran buyers through both numbers before they ever write an offer, because a house that looks affordable on a debt-to-income calculator can still stall if the residual income comes in short, and the reverse happens about as often.

The Test Most Buyers Never Hear About

Debt-to-income ratio asks a simple question: what share of gross monthly income goes to debt? Residual income asks something harder to fake: after every real bill is paid, what’s left over to live on? A veteran with no car payment and no credit card debt can post a low DTI and still come up short on residual income if their family is large and their income is modest. A veteran with a car loan and student debt can post a higher DTI and still clear residual income easily if their income covers it with room to spare. VA lenders are required to check both, under the underwriting standards written into 38 CFR 36.4340 and spelled out in the VA’s Lenders Handbook, Pamphlet 26-7, Chapter 4, current as of September 2026.

The maintenance and utility allowance built into the calculation is the part most buyers skip past. It’s not a guess. It’s based on square footage and region, meant to reflect what a home this size costs to keep running before the family spends a dollar on anything else.

What Houston Families Need Left Over Each Month

Texas sits in the VA’s South region. Here’s the minimum residual income required on loans of $80,000 or more, by household size:

Add $80 a month for each family member beyond five, up to seven. These numbers haven’t moved much in years because they’re built into the handbook itself rather than adjusted for inflation on a set schedule, which is exactly why so few buyers know them going in.

Can a 42 Percent DTI Still Close?

Here’s where the two tests meet head-on. The VA treats 41 percent as its reference point for debt-to-income ratio, not a hard ceiling. Go above it, and the file needs residual income at least 20 percent above the chart minimum to move forward without extra underwriting scrutiny.

Say a Houston veteran with a family of four brings home $6,500 a month before taxes. Their VA mortgage payment, principal, interest, taxes, and insurance combined, comes to $2,200. Other recurring debts, a car payment and a credit card, add another $550. That’s $2,750 in monthly obligations against $6,500 in income, a debt-to-income ratio of about 42.3 percent, over the VA’s 41 percent reference point.

The South region chart says a family of four needs $1,003 left over. Above 41 percent DTI, this family needs 20 percent more than that, roughly $1,204. If their actual residual income, after the mortgage payment, the debts, taxes, and the maintenance allowance, comes out to $1,320 a month, they clear the higher bar. The debt-to-income ratio alone would have made a conventional lender nervous. The residual income number is what gets this family to the closing table.

Why the VA Bothers With This At All

DTI treats every dollar of income the same, whether a veteran has one dependent or four. Residual income doesn’t. It’s a household-size math problem, not a percentage, which is closer to how a family lives inside a monthly budget. The VA built the standard this way on purpose, to catch the file that looks fine on paper but wouldn’t leave a family enough to cover groceries, gas, and a kid’s braces once the mortgage clears.

Peter spent years in mortgage lending before he ever held a real estate license, so a residual income worksheet isn’t new to him. It’s the same math he used to run for a living, long before he started walking Houston veterans through their own numbers. That background is why we ask a veteran buyer for their full debt picture early, not after they’ve fallen for a house that the DTI math says works and the residual income math says doesn’t.

If a disability rating is part of your income picture too, how a VA disability rating changes your buying power covers a separate piece of the qualifying math, the funding fee waiver and how disability compensation counts as income, that stacks on top of everything here rather than replacing it. And our VA loan guide walks through the rest of the financing process end to end.

A veteran who gets turned down on DTI alone, without anyone running the residual income numbers first, may have been turned down too soon.
