Fannie Mae rental-income rules: December 1 adoption deadline

What this means for your plan

The update reorganizes rental-income guidance and changes documentation for short-term rentals, leases and departing residences. It applies to Fannie Mae loan rules, not automatically to FHA, VA, jumbo or every investor program. The September 23 revision moved the required implementation date from November 1 to December 1, 2026 for new applications.

For a Seattle-area buyer planning to keep a current home as a rental, or an investor considering a short-term rental, the key question is which property and rental history the lender will evaluate. A projected rent figure is not an approval. Local permission to operate a short-term rental and property-management history may also matter. Ask the lender which documentation path applies and whether the rent can increase qualifying income or only offset a property payment.

Lenders may adopt the revised policy before December 1. The date on your application and the lender’s implementation determine which version is used. Compare the lender’s written qualification analysis with your own budget for vacancy, repairs, insurance, taxes and reserves.

Your next step

Before relying on rental income in a purchase or refinance budget, tell your lender the property, rental type and application timing; request the exact records and written qualifying-income calculation it will use.
