Jumbo Bonus, Overtime & Commission Income

Variable income is often usable, but history, trend and documentation can determine how much.

History and trend

Investors may review prior years and year-to-date earnings, whether income is increasing or declining, and whether the source is expected to continue. A short history may receive different treatment by different investors.

Avoid a blanket rule

There is no universal jumbo rule that every borrower needs exactly two years of every variable-income source. Verify the investor guideline and the stability of the actual earnings.

Investor rule or lender overlay? Jumbo mortgages do not have one Fannie/Freddie-style national underwriting handbook. A requirement may come from the end investor, a lender's own overlay, a specific product matrix, or the facts of the file. Hard thresholds should be verified against the actual program being offered.

Reference framework

FHFA conforming loan limits establish the conforming/jumbo boundary. For complex income concepts, the Fannie Mae income framework and Selling Guide provide useful conforming reference points—but a jumbo investor may calculate or document the same income differently.
