Fannie Mae Just Eliminated the Lease Requirement for Departing Residence Income — Here's What That Means for Move-Up Buyers

The Lease Requirement That Blocked Thousands of Move-Up Buyers Is Gone

If you've ever tried to buy a new home while keeping your current one as a rental — and been told by a lender that you needed a signed lease on your existing home before they could count any rental income toward your qualification — that roadblock just got removed.

On September 2, 2026, Fannie Mae issued Selling Guide Announcement SEL-2026-08. Buried inside a broader set of rental income updates is a genuine overhaul of how "departing residence" rental income works — and the most meaningful change is this: Fannie Mae is eliminating the requirement for an executed lease agreement as the primary documentation anchor for that income.

This is a real change with real implications for move-up buyers. Here's what it means, how it used to work, and why it matters.

What Is "Departing Residence" Rental Income?

Before we get into what changed, let's define the scenario. A "departing residence" situation occurs when a borrower is buying a new primary residence while converting their current home into a rental property rather than selling it. They're leaving the house — hence "departing" — but keeping it as an income-producing asset.

In this scenario, Fannie Mae has historically allowed lenders to count some portion of the future rental income from the departing home toward the borrower's qualifying income — or at least use it to offset the departing home's mortgage payment so it doesn't fully count against the borrower's debt-to-income ratio. That distinction between "income" and "offset" matters a great deal and we'll come back to it.

This rule quietly determines whether thousands of move-up buyers can qualify for their next home each year. It directly affects DTI. Get it right and the deal works. Get it wrong — or apply an outdated version of the rule — and a perfectly creditworthy borrower gets told no.

How the Old System Worked — And Where It Created Problems

Under the pre-SEL-2026-08 framework, using rental income from a departing residence required an executed lease agreement. Not a verbal commitment from a future tenant, not a letter of intent, not a market rent analysis — an actual signed lease. From there, two additional factors determined how much of that rental income actually helped you qualify:

The 75% factor. Fannie Mae required lenders to use only 75% of the gross monthly rent shown on the lease. The remaining 25% was assumed to cover vacancy, maintenance, and property management costs. So if your departing home would rent for $2,400 per month and you had a lease to prove it, the qualifying figure was $1,800 — not $2,400.

The landlord experience overlay. This is where it got more complicated. If you had less than 12 months of documented property management history — typically demonstrated through Schedule E on your federal tax returns — the rental income could only be used to offset the PITIA payment on the departing residence. It couldn't be added as positive income on top of your other qualifying income. If you had 12 or more months of verified landlord experience, the rules were more flexible and the income could be used more broadly.

So the old system created a very specific chicken-and-egg problem for move-up buyers: you often needed a signed lease on your current home to get credit for that rental income — but most sellers-turned-landlords don't have a tenant lined up until they're much closer to closing on their next purchase. Agents, real estate attorneys, and financial advisors routinely advised clients to secure a tenant and get a lease signed before applying — not because it was the most practical thing to do, but because the guidelines required it.

And if no lease existed at the time of application? That rental income couldn't be used. Period. For a borrower who needed that offset to qualify — or who needed that income to bring their DTI under the lender's cap — the deal simply didn't work.

One Myth Worth Correcting First

Before going further, I want to clear up something that comes up regularly in conversations with buyers and agents who have researched this topic.

You may have heard that Fannie Mae requires 20% or 30% equity in your departing residence before any rental income can be counted. That equity requirement was eliminated over a decade ago — it has not been in place since 2015. If you were told you needed a large equity cushion to use departing residence income under conventional guidelines, that information is outdated.

Documentation and landlord experience — not equity percentage — have been the real qualifying factors for years. SEL-2026-08 continues that trend by overhauling the documentation method itself, not reintroducing equity tests.

What SEL-2026-08 Actually Changes

The new framework moves away from lease-dependency entirely. Instead of requiring an executed lease as the primary income anchor, Fannie Mae is shifting to a model built on three pillars: market-supported rents, reserve requirements, and PITIA offset structuring.

Market-supported rents. Rather than requiring a signed lease, lenders can now use an appraiser's determination of achievable market rent — similar to how a Form 1007 (Single Family Comparable Rent Schedule) works — to document the rental income on a departing residence. The income is supported by what the market says the property can rent for, not by whether the borrower has already locked in a tenant.

This is the change that eliminates the chicken-and-egg problem. A borrower who is planning to convert their home to a rental — but hasn't yet signed a tenant — is no longer automatically disqualified from using that future income. The appraiser's market rent analysis becomes the documentation foundation.

Reserve requirements are now explicitly part of the equation. The new framework builds reserve standards directly into the departing residence calculation in a more structured way than before. Lenders are expected to verify that the borrower has sufficient post-closing reserves to service both properties during a transition period — not just that the income math works on paper for a single month. This is a reasonable addition and reflects how Fannie Mae is thinking about the genuine risk of carrying two mortgage payments through a lease-up period.

The PITIA offset structure remains, but within a new framework. For borrowers without 12 months of documented property management experience, the rental income is still primarily used to offset the departing residence's PITIA payment rather than added as fully positive qualifying income. That part of the logic hasn't changed. What's changed is how the underlying income figure gets documented and calculated to begin with.

The Before and After Side by Side

Here's how the key elements compare under the old rule versus SEL-2026-08:

Primary documentation required:
Old: Fully executed lease agreement
New: Market-supported rent (appraiser-based) — no signed lease required

How income is calculated:
Old: 75% of gross monthly lease rent
New: Based on market rent analysis with reserve and offset framework applied

Landlord experience overlay:
Old: Less than 12 months = offset-only; 12+ months = broader use
New: PITIA offset limitation still applies for newer landlords, within updated framework

When it can be used:
Old: Requires signed lease — must have a tenant in place
New: Can be used based on market rent — tenant not required at application

Mandatory effective date:
Old: Applies through October 31, 2026
New: Mandatory for all applications dated November 1, 2026 and later; lenders encouraged to adopt immediately

Why This Matters in Practice

Let me give you a concrete scenario to illustrate why this change is meaningful.

A borrower in Phoenix bought their home in 2021 at a 3% rate. They want to upsize — growing family, more space needed. Their current home would rent for $2,200 per month based on comparable rentals in their neighborhood. They don't want to sell because they'd be giving up a 3% mortgage that makes the property cash-flow positive as a rental.

Under the old system: they'd need to find a tenant, negotiate a lease, and get it signed before their lender could use that $2,200 (or 75% of it — $1,650) to offset the departing home's mortgage payment in their DTI calculation. Without that signed lease, the entire $2,000 monthly payment on their current home counted as a debt against them when qualifying for the new purchase — potentially making the deal impossible to underwrite.

Under SEL-2026-08: an appraiser confirms the market rent at $2,200. That market-supported figure now anchors the income calculation. The borrower doesn't need a signed lease to use it. The DTI math changes immediately. The deal that couldn't be underwritten under the old rules becomes workable before a tenant is even identified.

For borrowers holding low-rate mortgages from 2020–2022 — properties that make tremendous financial sense to keep as rentals at today's market values — this opens a real path to move up without being forced to sell an asset they'd be far better off holding.

What This Means for Real Estate Agents

If you've been advising move-up clients to sell their current home because "they can't qualify with two mortgages" — it's worth revisiting that assumption now.

A significant portion of the clients who were told they couldn't qualify for a new purchase while converting their current home to a rental were running into the lease documentation wall specifically. The income math often worked. The equity was often there. What was missing was a signed lease at the time of application — something that wasn't practical to have in place at that stage of the process.

That barrier is now gone under the new framework. Some of those deals that were structured as sales to qualify — when the client would have strongly preferred to hold the property as a rental — should be reexamined. The math may look different today than it did even three months ago.

Important Nuances to Know Before You Apply

Lender adoption varies right now. Fannie Mae's mandatory effective date is November 1, 2026, but lenders are explicitly encouraged to implement the changes immediately. Some lenders are already underwriting to the new standard. Others are still on the old system. This means two lenders quoting you today may be working from different rule sets — which is exactly why comparing quotes across multiple lenders matters more than ever for this specific scenario.

The landlord experience overlay still applies. The PITIA offset limitation for borrowers without 12 months of documented property management experience is still part of the new framework. This isn't being eliminated — the income can now be documented without a lease, but how it's applied in the DTI calculation still depends in part on your experience as a landlord.

Reserves will be scrutinized more explicitly. The new framework builds reserve requirements into the departing residence calculation more formally than before. Make sure your post-closing reserves are strong going into any dual-mortgage underwrite — it will be part of the analysis in a more structured way now.

Other rental income changes came in the same announcement. SEL-2026-08 also includes new documentation standards for short-term rental income, updated rules for investment properties purchased within 45 days of the subject property, and tighter lease validation standards generally — including restrictions on non-arm's-length arrangements. If your scenario involves any of those elements, more than one update may apply to your file.

The Bottom Line

This is one of the more borrower-friendly changes Fannie Mae has made to conventional qualifying guidelines in recent memory. The lease requirement was a legitimate operational hurdle that blocked real, creditworthy borrowers from using income they were going to have — simply because they hadn't yet signed a tenant at the time of their mortgage application.

Replacing it with a market-rent appraisal approach is cleaner, more accurate, and more reflective of how the actual decision-making process works for a homeowner converting their property to a rental. The income support comes from the market, not from a tenant whose lease may or may not be representative of what the property is actually worth.

If you've been told in the past that keeping your current home as a rental wasn't workable from a qualifying standpoint — and the reason was the lease requirement or the DTI math that came with it — that conversation deserves a fresh look under the new framework.
