Departing Residence Rental Income
Turning a current primary residence into a rental while buying another home has specific rental-income rules and should not be treated like a generic investment-property lease.
Separate category
Fannie Mae's current Selling Guide has a dedicated departing-residence rental-income section.
Lease limitation
Fannie's September 2026 general rental guidance says a lease agreement is not permitted to determine qualifying rental income when the investment property is a departing residence.
Housing history matters
Rental-income eligibility and treatment can depend on current housing payment and property-management experience.
Do not use an old shortcut
Use the current agency scenario rather than a remembered universal percentage or equity rule.
Stop using old departing-residence shortcuts
Fannie created a dedicated departing-residence rental category in the September 2026 Guide. Use current documentation and income-treatment rules, then separately analyze property count and reserves.
Documents I would gather before calculating rental income
Current mortgage statements/PITIA for every retained property; Schedule E and applicable tax returns; leases; purchase closing statements and acquisition dates; appraisals or rent schedules when applicable; proof of current housing payments; insurance/HOA information; entity documents if an LLC is involved; and evidence of reserves. The correct calculation depends on what the property is and when/how it was acquired.
Common investor-loan mistakes
Calling 75% of rent 'income' without subtracting PITIA; using a lease when current agency policy requires another rent source; adding positive rental income when it is only allowed to offset housing expense; confusing cap rate with DSCR; applying a private investor's seasoning rule to Fannie/Freddie; and assuming an LLC-owned mortgage is counted the same as a personally obligated mortgage.
