Renting Out the Home You're Leaving: The New Departing Residence Rule
Starting with applications dated November 1, 2026, Fannie Mae's new departing residence rule (Selling Guide B3-3.8-05) only lets 75% of the market rent on your old home offset its full mortgage payment, never add to your income. A lease no longer counts as proof: you need an appraiser's opinion of market rent or three comparable listings. Rent has to run about 1.333 times the old payment before it fully cancels that payment out of your debt-to-income ratio.
If you're buying a new primary residence and keeping the old one as a rental, lenders have always wanted proof the departing property won't drag down your debt-to-income ratio. Fannie Mae just rewrote that proof requirement, and the new version is tighter than anything the agency has published on this topic before.
Announcement SEL-2026-08 created a brand-new Selling Guide section, B3-3.8-05, dedicated entirely to departing residences. It's mandatory for any conventional loan application dated November 1, 2026 or later. Applications dated before that can still be structured under the old lease-based method, but anything you're planning for after that date needs to run on the new math from day one.
What exactly does the new departing residence rule require?
The rule applies when you're keeping your current home and financing a new primary residence, and the departing home's payment would otherwise count against your debt-to-income ratio. Under B3-3.8-05, only 75% of the market rent on that departing home can be used, and it can only be netted against the departing home's own full payment, principal, interest, taxes, insurance, and any association dues included. It can never flow through as additional qualifying income on the new loan. That's a meaningful shift: lenders used to let strong rental income help a borrower qualify for more house. Now the departing home's rent can only cancel its own debt, nothing more.
How much rent do I need to fully offset the old payment?
Because only 75% of market rent counts, the rent has to be higher than the payment itself for the offset to reach zero. Work it out as a ratio: multiply the full payment by roughly 1.333, and that's about where market rent needs to land for the 75% calculation to fully cancel the payment out of your ratios. Fall short of that and the leftover difference still counts against you in underwriting. Run your own numbers through the Income Qualifier calculator before you order an appraisal, since it's a quick way to see whether your departing home's rent potential actually clears that bar.
What counts as proof of market rent now that a lease won't work?
A signed lease, even one with a paying tenant already in place, is no longer acceptable evidence under the new rule. Fannie Mae wants one of two things instead: an appraiser's opinion of market rent (typically documented on a rental schedule as part of the appraisal), or at least three comparable rental listings pulled independently of any lease you may have signed. The logic is straightforward from the agency's side: a lease reflects what one landlord negotiated with one tenant, not what the market will actually bear. An appraiser's opinion or a set of real comparables is harder to game and easier to verify.
Do you need reserves if you don't have landlord experience?
Yes, and this is one of the parts of the rule that catches borrowers off guard. If you have less than 12 months of documented property management experience, Fannie Mae requires six months of the departing home's full payment held in reserves, separate from whatever reserves the new loan already requires. The agency treats a first-time landlord as a bigger risk of vacancy or mismanagement, and the reserve requirement is the hedge against that. Twelve months of documented experience, whether through a prior rental property, a property management role, or similar, removes this extra reserve layer.
How does FHA handle a departing residence differently?
FHA's version of this rule, laid out in HUD Handbook 4000.1, is stricter in a different direction. FHA requires the borrower to be relocating more than 100 miles from the departing residence, and requires at least 25% equity in that property before any rental offset is allowed. FHA also still accepts a lease, but it has to run at least one year, which is the opposite of Fannie Mae's new lease ban. In practice, FHA's rule is harder to clear for someone staying in the same metro area and keeping a condo as a rental, since the distance test alone disqualifies most local moves.
Does VA count departing residence rental income the same way?
VA allows prospective rent from the departing residence to offset that property's payment in the loan analysis, the same never-add-income philosophy Fannie Mae now applies. The difference is in how VA underwriters use the number: VA loans are evaluated on residual income rather than a strict DTI ratio, so the rent offset affects the residual income calculation rather than a debt-to-income percentage. Either way, the rent reduces the drag from the old payment; it does not become income that helps you qualify for a larger new loan.

What if the departing home doesn't clear the rent math?
Some borrowers find the 1.333x threshold out of reach, especially in markets where rents haven't kept pace with payments on homes bought at lower rates years earlier. In that case, the departing home's full payment stays in your DTI with no offset, which can shrink what you qualify for on the new purchase. One alternative worth exploring is converting the departing home into a straight investment property loan instead of running it through the departing residence offset at all. A DSCR-based option qualifies the rental off the property's own cash flow rather than your personal income or departing payment math; the DSCR calculator will show roughly where that property's rent-to-payment ratio sits before you decide which path to take.
What should you do before you apply under the new rule?
Order the rent documentation early. If you're going the appraiser route, make sure the appraisal is scoped to include a rental schedule, not just a standard purchase appraisal, since that's where the market rent opinion comes from. If you're pulling comparable listings instead, three solid, truly comparable units beats a longer list of loosely similar ones. Check your equity position on the departing home regardless of which program you're using, and pull together documentation of any prior landlord experience now rather than scrambling for it mid-file. Because this rule is new and the specifics depend on your loan date, equity, and whether you're going conventional, FHA, or VA, it's worth walking through your actual numbers with a loan officer before you write an offer on the new home.
Frequently asked questions
When does Fannie Mae's departing residence rule take effect?
It's mandatory for conventional applications dated November 1, 2026 or later, under Announcement SEL-2026-08 and Selling Guide section B3-3.8-05. Applications dated before that can still use the prior lease-based method.
Can I still use a signed lease to prove rental income on the home I'm leaving?
No. Under the new rule a lease is no longer acceptable evidence of market rent. You need either an appraiser's opinion of market rent or at least three comparable rental listings.
How much rent do I need to fully cancel out my departing home's payment?
Roughly 1.333 times the full payment, since only 75% of the market rent is counted and that 75% figure has to equal 100% of the payment to zero it out.
Can departing residence rental income ever add to my qualifying income?
No. Fannie Mae's rule only allows the rent to offset the departing property's own payment. It can never be used as additional income to help qualify for the new mortgage.
What reserves are required if I've never managed a rental before?
If you have less than 12 months of documented property management experience, Fannie Mae requires six months of the departing home's full payment in reserves, on top of any reserves required for the new loan.
Is FHA's departing residence rule the same as Fannie Mae's?
No, FHA is stricter under HUD Handbook 4000.1. It requires relocating more than 100 miles from the departing home, at least 25% equity in that property, and a signed lease of at least one year.
Does a VA loan let me count rent from my old home as income?
VA allows prospective rent from the departing residence to offset that home's payment in the loan analysis, but it never counts the rent as qualifying income.
What if I don't want to deal with any of this documentation?
Borrowers who'd rather skip the departing residence offset calculation entirely sometimes finance the old home as a straight investment property using a DSCR loan instead, which qualifies off the property's own rent rather than the borrower's departing payment math.
