Keeping your current home as a rental while buying your next one sounds simple in theory. In practice, whether you can actually use that future rent to help you qualify depends heavily on one thing most buyers never think to ask upfront: what type of loan are you using for the new purchase? FHA and conventional financing handle this exact scenario very differently, and the gap between them is bigger than most buyers realize.
The Core Difference, Up Front
Conventional loans (through Fannie Mae or Freddie Mac) will let a first-time landlord use departing residence rental income as an offset against the old mortgage payment, even without any prior landlord experience. FHA takes a much harder line, in two ways. First, FHA's handbook says rental income from the home you're leaving can only be used if you're relocating more than 100 miles from it. Second, without landlord experience, FHA generally requires both an appraisal establishing market rent and at least 25% equity in the departing home, not either one alone, both together.
That's a meaningfully higher bar, and it's the kind of thing that can quietly derail a move-up purchase if it surfaces after you've already gone under contract instead of before.
How Conventional Handles It
Under Fannie Mae's standard framework, if you don't have a documented year of property management experience, rental income from your departing residence can still be used, just in a more limited way, generally as an offset against the old home's PITIA payment rather than as income added on top. With landlord experience, the restrictions loosen further. And as of Fannie Mae's most recent update, the documentation path has moved away from strict lease-dependency toward market-supported rent, meaning an appraiser's rent determination can carry real weight even without a signed lease in hand yet.
The equity cushion that used to be a major hurdle here was actually retired from conventional lending back in 2015. If you've heard you need 25-30% equity in your departing home to use conventional rental income, that hasn't been true in over a decade, that requirement is specific to FHA, not conventional.

How FHA Handles It
FHA's approach is structured around risk in a different way, and the first hurdle has nothing to do with your income or your equity. Under FHA's handbook, to use rental income from the home you're moving out of, you must be relocating to an area more than 100 miles from your current primary residence. A buyer moving across town, or even to the next county, for a bigger house, a very common move-up scenario, generally can't use the departing home's rent on an FHA loan at all, no matter how strong the rest of the file looks. It's a rule conventional financing simply doesn't have.
If you clear the distance requirement, the next question is landlord experience. With documented rental history, the process is more straightforward and closer to how conventional handles it. Without that history, FHA requires both a fresh appraisal establishing market rent for the departing property and confirmation that you hold at least 25% equity in that home. Miss any of those conditions, and the rental income generally can't be used to help you qualify, not even as a partial offset.
This is exactly the kind of program-specific detail that's easy to miss until it's already a problem mid-transaction.
Why This Gap Actually Matters
Picture two buyers with identical situations: solid income, decent credit, keeping their current home as a rental, no prior landlord experience, and only 15% equity in their departing home. On a conventional loan, that buyer can likely still use the departing residence's rental income as an offset against the old payment, no equity cushion required. On FHA, that same buyer likely can't use any of it. If they're moving within the same area, the 100-mile rule rules it out on its own, and even a long-distance move would run into the 25% equity threshold.
That's not a small distinction. It can be the difference between a move-up purchase that works on paper and one that doesn't, purely based on which loan program got selected before anyone ran this specific scenario.
A Worked Example
Say your current home has a $2,800 monthly PITIA payment, and you'd realistically rent it for $2,600 a month once you move out. You don't have prior landlord experience, you have about 15% equity built up, not the 25% FHA wants to see, and the new home is 20 minutes away.
On the conventional side, that $2,600 in market-supported rent can be used to offset your $2,800 PITIA. The math nets out to roughly a $200 monthly shortfall counted against your debt-to-income ratio, not the full $2,800. That's a meaningfully lighter load on your file than carrying the entire old payment with zero credit for the rent coming in.
On the FHA side, a 20-minute move fails the 100-mile test, and with no landlord experience and only 15% equity you'd fall short on the equity requirement too, so you generally can't use any of that $2,600 in rental income at all. The full $2,800 old payment counts against your DTI in addition to whatever your new mortgage payment will be. For a lot of buyers, that's enough to push the file from "comfortably qualifies" to "doesn't qualify," or at minimum, "qualifies for meaningfully less home than expected."
Same buyer, same rental property, same numbers, two very different outcomes, purely based on loan type.
Which One Should You Actually Use?
This isn't a blanket "conventional is always better" situation, FHA still makes sense for plenty of buyers, particularly those with lower credit scores or less available for a down payment. But if your plan involves keeping your current home as a rental and you're not moving more than 100 miles away, conventional financing is very likely going to give you meaningfully more usable rental income than FHA will. Landlord experience and equity matter too, but on FHA the distance rule usually decides it first. That's a conversation worth having before you pick a loan type, not after.

Frequently Asked Questions
What is FHA's 100-mile rule for rental income?
To use rental income from the home you're vacating on an FHA loan, FHA's handbook requires that you're relocating more than 100 miles from your current primary residence. Conventional financing has no equivalent distance requirement. A separate 100-mile exception also governs holding two FHA loans at once, which is a different question.
Do I need 25% equity in my current home to use rental income on any loan type?
No, that requirement is specific to FHA when you lack landlord experience. Conventional financing retired its equity cushion requirement for departing residence income back in 2015.
What counts as landlord experience for these purposes?
Generally, a documented history of managing a rental property, often shown through prior tax returns reporting rental income. Requirements on exactly how long that history needs to be can vary by program and lender.
Can I switch from FHA to conventional if the rental income math doesn't work?
Often yes, if you qualify for conventional financing on the rest of your profile. This is exactly the kind of scenario worth running both ways before you're locked into a specific loan type and a signed purchase contract.
Does the new Fannie Mae update change anything about the FHA side of this?
No, the recent update is specific to conventional financing through Fannie Mae. FHA's rules on departing residence rental income are unaffected by that change.
The Bottom Line
If keeping your current home as a rental is part of your plan, the loan type you choose for your next purchase can meaningfully change whether that future rent actually helps you qualify. FHA's 100-mile distance rule, plus its landlord-experience-or-equity requirement, is a real and often deal-breaking hurdle for local move-ups that conventional financing doesn't share. Worth running the numbers on both before you commit to either path.
