Fannie Mae Just Changed How "Departing Residence" Rental Income Works — Here's What That Means For Move-Up Buyers
If you're buying a new home while keeping your current one as a rental, Fannie Mae just rewrote the rulebook on how that future rent counts toward qualifying. This is SEL-2026-08, and it's a real, meaningful shift — not a minor tweak. NMLS #137512.
Get Pre-Approved — It's Free"Departing residence" rental income is the income Fannie Mae lets you count from the home you're leaving — the one you plan to keep and rent out — when you're qualifying for the mortgage on your next home. This single rule quietly decides more move-up purchases than almost anything else in conventional lending, because it directly affects how much house you can qualify for while carrying two properties.
On September 2, 2026, Fannie Mae issued Selling Guide Announcement SEL-2026-08, and buried inside it is a genuine overhaul of how this specific type of rental income gets calculated. We've been watching this one closely because it affects a real slice of our move-up buyer clients.
How This Worked Before SEL-2026-08
Under the old system, using rental income from your departing residence required an executed lease on that property. From there, two things determined how much of it actually helped you qualify:
- The lender counted 75% of the gross monthly rent shown on the lease — the remaining 25% was assumed to cover vacancy and maintenance, so it was never counted at all.
- Your landlord experience determined the ceiling. If you had less than 12 months of documented property management history, that 75% rent figure could only be used to offset the PITIA payment on the departing home — it could reduce that payment's drag on your debt-to-income ratio, but it could never add positive income on top. If you had 12+ months of landlord history (typically shown via Schedule E on your tax returns), the income could be used more fully, not just as an offset.
One thing worth clearing up while we're here: the old requirement that you needed a large equity cushion in your departing home before any rent could count was retired back in 2015. If you've heard that "you need 30% equity to use departing residence income," that's outdated — it hasn't been true in conventional lending for over a decade. Documentation, not equity percentage, has been the real gatekeeper for years.
What SEL-2026-08 Actually Changes
Fannie Mae is moving away from a lease-dependent model entirely for departing residence income. The new framework is built on three pillars instead: market-supported rents, reserve requirements, and PITIA offset limitations — rather than requiring an executed lease agreement to document the income in the first place.
Why This Is a Bigger Deal Than It Sounds
The old system created a real chicken-and-egg problem for move-up buyers: you often needed to already have a signed lease on your current home to get credit for that rental income — but plenty of sellers-turned-landlords don't have a tenant lined up until they're closer to actually closing on their next house. Shifting toward market-supported rents (an appraiser's opinion of achievable rent, similar to how a rental comparable schedule works) means the income can potentially be documented and used earlier in the process, without needing a tenant already in place.
| Factor | Old Rule (Before Nov 1, 2026) | New Rule (SEL-2026-08) |
|---|---|---|
| Primary documentation | Executed lease agreement required | Market-supported rent (appraiser-based), not dependent on a signed lease |
| Core structure | 75% of lease rent, offset-only without landlord history | New framework built on market rent + reserve requirements + PITIA offset limits |
| Effective date | Current standard through October 31, 2026 | Mandatory for applications dated November 1, 2026 and later; lenders may adopt early |
| Related lease rules elsewhere in rental income policy | Existing standard lease validation | Strengthened: minimum lease term requirements, enhanced validation, tighter restrictions on non-arm's-length leases |
Other Rental Income Changes in the Same Announcement
SEL-2026-08 wasn't just about departing residences. The same announcement also introduced new documentation options for short-term rental income, standardized how rental income is calculated on investment properties purchased within 45 days of the subject property, and tightened lease agreement standards broadly — including new minimum lease term rules and restrictions on non-arm's-length lease arrangements (think: renting to a family member at a below-market rate). If you're financing an investment property alongside a departing residence scenario, more than one of these changes may apply to your file.
Why Reserve Requirements Are Now Part of the Equation
Building reserve requirements directly into the departing residence framework is a meaningful signal about how Fannie Mae is thinking about risk here. Historically, reserves and rental income calculation lived in somewhat separate lanes. Tying them together for departing residences suggests underwriters will be looking more holistically at whether a borrower can genuinely weather the transition period between two mortgage payments — not just whether the math pencils out on paper for a single month.
Exact Numbers Are Still Rolling Out — Here's What To Do About It
Fannie Mae's announcement lays out the new framework's structure, but the specific worked formulas — the exact offset percentages, reserve months, and market rent documentation standards — are being finalized in the updated Selling Guide sections as lenders transition onto the new system between now and November 1. Because lenders are permitted (and encouraged) to adopt early, it's genuinely possible that two lenders quoting you today are working from two different rule sets. This is exactly the kind of moment where working with someone who's tracking the actual guide updates — not just repeating last year's rule of thumb — makes a real difference in what you're told you qualify for.
What This Means If You're Planning a Move-Up Purchase
- If you're closing before November 1, 2026, ask your lender directly whether they're already using the new framework or still on the old lease-dependent model — it affects what documentation you need to gather right now.
- If you don't have a tenant lined up yet for your departing residence, the shift toward market-supported rents may open up options that weren't available to you under the old lease-dependent system — worth a fresh conversation even if you were told "no" under the old rules.
- If you have less than 12 months of landlord experience, the PITIA offset limitation is still part of the new framework's structure — this isn't going away, it's just being calculated within a different overall system.
- Reserves matter more explicitly now. Start thinking about your post-closing liquid reserves as a real part of this calculation, not an afterthought.
Frequently Asked Questions
Do I need a signed lease to use rental income from my departing residence?
Under the old rule (effective through October 31, 2026), yes — an executed lease was required. Under the new framework in SEL-2026-08, Fannie Mae is moving toward market-supported rents instead, meaning the income can potentially be documented without a signed lease already in place. Exact documentation requirements are still being finalized as lenders transition onto the new system, so confirm directly with your lender which framework applies to your file.
When do these changes actually take effect?
The rental income policy revisions in SEL-2026-08 are mandatory for all loan applications dated November 1, 2026 or later. However, Fannie Mae explicitly encourages lenders to implement the changes immediately, which means some lenders may already be underwriting to the new standard before the mandatory date.
Is it true I need a certain amount of equity in my current home to use rental income?
No — that requirement was retired from conventional lending back in 2015. If you've heard you need 20% or 30% equity in your departing residence before rent can count, that information is outdated. Documentation and landlord experience have been the real determining factors for years, and SEL-2026-08 continues that trend by shifting the documentation method itself rather than reintroducing an equity test.
I don't have 12 months of landlord experience — does this new rule help me?
The PITIA offset limitation for borrowers without 12 months of documented property management experience remains part of the new framework's structure — that specific limitation isn't being removed. What's changing is how the underlying rental income gets documented and calculated in the first place, shifting away from lease-dependency toward market-supported rents and reserve requirements.
Does this affect Freddie Mac loans too?
SEL-2026-08 is a Fannie Mae Selling Guide announcement specifically. Freddie Mac maintains its own separate rental income guidelines, and while the two agencies' rules on departing residence income have historically tracked closely together, any changes on the Freddie Mac side would come through their own Bulletin process. We track both agencies' updates and will tell you which set of rules applies to your specific loan program.
