Three Things an Underwriter Checks Before Your Overtime Income Counts

Three Boxes Your Paycheck Has to Check

Three things an underwriter looks for before they'll count your income on a conventional loan: is it stable, is it predictable, and is it expected to continue. If your pay doesn't check all three boxes, that income might not count at all - no matter how real the money is.

A situation that comes up often is a buyer who recently switched jobs and now earns overtime pay as part of their income. That was the case for Adelyn, a buyer near Johnsonville, SC. Her new job paid well, but the overtime was brand new on paper, and overtime is exactly the kind of income lenders look at hardest, because it can start and stop without warning.

What the Guideline Actually Says

Fannie Mae's Selling Guide, under B3-3.1-01, lays out the standard conventional lenders use: "Income must be stable, predictable, and expected to continue. The lender must verify employment and income through pay stubs, W-2s, and tax returns as applicable."

Notice there are three separate requirements packed into that sentence. Stable means it isn't erratic from month to month. Predictable means there's a pattern a lender can actually calculate. Expected to continue means there's a reasonable basis to believe it keeps going after closing, not just that it happened once. Overtime, bonus, and commission income all get measured against this same three-part test, and a new job makes that test harder to pass without the right paperwork.

How This Played Out for Adelyn

For a buyer in Adelyn's position, the fix isn't creative math, it's documentation. We typically pull a pay stub history long enough to show a pattern, prior W-2s when available to establish a baseline, and often a written statement from the employer confirming the overtime is expected to continue rather than a short-term spike in hours. Put together, that package is what lets an underwriter move overtime income from "maybe" to "counted."

This is also why timing matters. A buyer who just switched jobs may need a few pay cycles before that overtime pattern is documentable, and knowing that ahead of time avoids a surprise mid-contract.

The One Question to Ask

Here's the tactical piece you can use immediately, whether you're working with me or anyone else: ask your loan officer, "Can you tell me which parts of my income qualify as stable and continuing under B3-3.1-01, and what documentation you need to verify each one?" That question forces a specific answer instead of a vague "we'll see." You'll know within one conversation whether your overtime, bonus, or commission income is going to qualify, and exactly what to gather if it isn't there yet.

Why This Matters Before You Shop for a House

Income qualification issues are far easier to solve before you're under contract than during a tight closing timeline. If your pay structure changed in the last year or two, whether that's a new job, new overtime eligibility, or a shift to commission, it's worth having this conversation early, not after you've found the house.
