A borrower's overtime was $8,000 last year and $5,000 the year before; this year it is on pace for $2,500. How should an underwriter view this overtime?
Variable income such as overtime must be stable or increasing to be used; a declining trend requires the lender to analyze the reasons and may mean using the lower current amount or excluding it (Fannie Mae Selling Guide B3-3.3-02, dated Mar 4, 2026: if income is decreasing, the lender must confirm it has stabilized, otherwise it is not eligible). A sharp year-to-date drop is a red flag for stability. Source: Fannie Mae Selling Guide, B3-3.3-02 (Mar 4, 2026) (as at 11 Oct 2026).
Averaging overtime without noticing it is falling.
