How to Find Homes With Assumable Mortgages (Because Zillow Won't Show You)

NPR reported a comparison earlier this year that perfectly illustrates the assumable mortgage discovery problem. A search for homes in Houston with assumable mortgages on Roam, one of the new platforms built specifically for this market, returned 433 listings with rates at or below 3%. The same search on Zillow, which relies on sellers to self-report whether their mortgage can be transferred, returned three. Not 300. Three.

That gap exists because the traditional real estate infrastructure was never built to surface this information. MLS listings don't flag whether a mortgage is assumable. Most listing agents don't know to ask. And 98% of eligible sellers have no idea their mortgage can be transferred to a buyer, according to Assumable.io, which operates what it describes as the largest national database of assumable listings (50,000+ active listings across all 50 states). If you want to know how to find homes with assumable mortgages, you need to understand that the standard house-hunting playbook will miss almost all of them.

This matters because the savings are enormous. The 30-year fixed mortgage rate sits at roughly 6.1% to 6.4% as of mid-April 2026 (CBS News, Bankrate). Meanwhile, 20% of outstanding mortgages carry rates below 3%, and the average rate across all existing mortgages is 4.4%, according to the Bipartisan Policy Center. On a $400,000 balance, the difference between a 3% rate and a 6.3% rate is roughly $800 per month in principal and interest. Over a full 30-year term, that compounds to more than $200,000 in total interest savings (the actual savings depend on the remaining term of the assumed loan, which is typically 25 to 27 years for a mortgage originated in 2020 or 2021). Only about 6,000 assumptions were completed nationally in 2023, despite roughly 6 million eligible homes. That's a conversion rate of 0.1%. The opportunity is massive. The infrastructure to find it is just now catching up.

The three platforms that actually find them

The assumable mortgage search market barely existed two years ago. Now three platforms are competing to solve the discovery problem, each with a different approach.

Roam (withroam.com) is the most prominent and best-funded. Backed by Opendoor co-founder Eric Wu and Founders Fund's Keith Rabois (with additional investment from DoorDash CEO Tony Xu and Figma CEO Dylan Field), and with former Fannie Mae CEO Tim Mayopoulos as a senior advisor, Roam operates in 23 states and lists homes with assumable mortgages featuring rates as low as 2%. Roam's founder, Raunaq Singh, previously led the mortgage product at Opendoor, which partially explains the November 2025 partnership between the two companies: Opendoor now surfaces Roam's assumable mortgage tools on its own platform. Roam charges buyers a 1% fee at closing based on the sale price. Each listing includes a built-in blended rate calculator so you can see the real cost before getting emotionally attached to a 2.75% headline rate. Roam also partnered with national lender Spring EQ to offer second mortgages through a program called Roam Boost, available to buyers with a 640+ credit score and at least 15% down.

Assumable.io has the widest geographic reach, operating in all 50 states with a database of more than 50,000 active listings across 6,500 cities. Their team analyzed 312,367 assumable mortgages listed from 2023 to 2025. A survey of 2,621 of their customers found the average buyer saves $1,187 per month compared to buying at current rates ($14,244 per year). The platform also offers an "Assumable Pro" tier for agents, brokers, and investors that includes off-market data. Where Roam operates as a concierge service with a fee, Assumable.io functions more like a search engine.

AssumeList maintains a database tracking properties with FHA and VA loans, and its most useful feature is showing the seller's exact interest rate before you even contact an agent. AssumeList is also the source of the widely cited estimate that 6 million homes carry assumable mortgages with rates below 5%.

We covered the mechanics of how assumptions work, the blended rate math, and who should and shouldn't pursue one in our assumable mortgage guide. This article is the next step: how to actually locate these properties and evaluate whether a specific listing is worth pursuing.

How to search without a platform

The platforms are useful but not comprehensive. Homes with assumable mortgages exist in every market; the platforms just haven't indexed all of them. Here's how to find them on your own.

Start by asking listing agents directly whether the property has an FHA, VA, or USDA loan. This information isn't in most MLS listings, but the seller's agent can find out from the seller or from the loan servicer. If the agent doesn't know what you're talking about (and many won't), that's actually a signal: you've found a market where assumable mortgages aren't being marketed, which means less competition.

Public records can help. In most counties, mortgage origination documents are recorded and searchable. FHA loans will reference HUD or the Department of Housing and Urban Development. VA loans will reference the Department of Veterans Affairs. These searches take time, but they're free and can identify properties that no platform has flagged.

Target neighborhoods near military installations. VA loans are concentrated around bases, and these are the loans with the lowest rates (74% of VA homeowners hold rates below 5%, according to a Veterans United analysis of Ginnie Mae data from March 2025). Fort Cavazos in Texas (formerly Fort Hood), Camp Pendleton in California, Joint Base Lewis-McChord in Washington: the areas surrounding major military installations tend to have the highest concentration of assumable VA mortgages.

Look for homes purchased between 2020 and 2022 with high original loan-to-value ratios. These are your best targets for two reasons. First, the rates were historically low during that period (often 2.5% to 3.5%). Second, owners who put less money down have built less equity, which means a smaller gap between the loan balance and the current home value. That smaller gap is easier to cover at closing. A home bought in 2021 with 3.5% down on an FHA loan will have a much more manageable equity gap than one bought in 2018 and refinanced during COVID.

One more tactic that gets overlooked: filter for listings that have been on the market for 60 or more days. Sellers who are struggling to attract buyers are more motivated to cooperate with an assumption, which requires their active participation. The seller must initiate the assumption process due to federal privacy laws; a buyer can't go directly to the servicer. A motivated seller is a cooperative seller, and that cooperation matters more than anything when the servicer processing timeline starts stretching.

The equity gap determines whether the deal actually works

Finding an assumable mortgage is only half the problem. The other half is paying for the gap between what the seller owes and what the home is worth.

If a home is listed at $450,000 and the seller's remaining mortgage balance is $330,000, the buyer needs to cover a $120,000 equity gap. That's the sale price minus the loan balance, and it must be paid in cash, through a second mortgage, through seller financing, or some combination. For a first-time buyer putting down 3.5% on an FHA loan, the standard down payment on that home would be roughly $16,000. The equity gap is nearly eight times that.

This is where the equity math gets uncomfortable. As one Austin-based real estate professional observed, paraphrasing research from the Urban Institute's Laurie Goodman: assumable mortgages tend to benefit people who already have money. The buyer who can write a $120,000 check is in a very different position than a first-time buyer scraping together 3.5% down. The assumption ecosystem currently favors people who are selling one home and buying another, or who have significant savings.

For buyers who can't cover the gap in cash, a second mortgage at current market rates (8% to 9% for a second lien in 2026) is the most common workaround. The key math here is the blended rate. Assume a $250,000 first mortgage at 3.25% and take a $100,000 second at 8.5%: the blended rate across both loans works out to roughly 4.75%, according to calculations from askdoss. That's still well below a new 6.3% conventional loan. But if the equity gap is enormous (say, $200,000 on a $500,000 home), the blended payment can actually exceed what you'd pay on a single new mortgage. EffectiveAgents ran the numbers on exactly this scenario and found the assumption was more expensive in the short term.

The rule of thumb from multiple mortgage professionals: the assumption is most advantageous when the equity gap is 20% or less of the home's total value.

Roam's partnership with Spring EQ (called Roam Boost) is trying to solve part of this problem, offering second mortgages to buyers with 640+ credit scores and 15% down, targeting a 4% to 5% blended rate. But second-lien products for assumption gaps are still a growing category, and not all lenders offer them.

The servicer problem nobody warns you about

Federal rules require mortgage servicers to process assumptions within 45 days. VA Circular 26-23-27, issued in December 2023, specifically mandated this timeline for VA loans. HUD Handbook 4000.1 sets the same 45-day ceiling for FHA assumptions.

In practice, the timelines run longer. Simple assumptions can close in 30 to 45 days. Complex cases, particularly with major servicers handling high volumes, can take 60 to 120 days or longer. Multiple industry sources and mortgage professionals confirm that actual processing times regularly exceed the mandated window. Consumer Financial Protection Bureau complaints about servicer delays in processing assumptions more than doubled, from 67 in 2021 to 149 in 2023, according to data compiled by AmeriSave.

NPR reported in February 2026 that a buyer named Brendan Burroughs tried to assume a Florida mortgage with a 2.5% rate. His servicer, Mr. Cooper, told him 1,500 people were ahead of him in the queue and he'd have to wait. He then heard nothing for a month. (Mr. Cooper's spokesperson pushed back on parts of this account, saying the timeline matched industry norms.)

The friction is partly structural. Ted Tozer, the former president of Ginnie Mae and a fellow at the Urban Institute, has explained that servicers "don't love assumptions" because "under government rules they can't charge enough to cover their processing costs." That cost problem is a major reason HUD doubled the maximum FHA assumption fee from $900 to $1,800 in a May 2024 update to Handbook 4000.1, effective August 2024. The fee increase was explicitly designed to make it economically viable for servicers to actually staff up and process these transactions.

Companies like Assumption Solutions (run by Craig O'Boyle, who acknowledges that the process "can take months" despite the 45-day rule) and Assume Loans exist specifically to push servicers through the process faster. Roam provides similar servicer coordination as part of its 1% fee. If you're pursuing an assumption without one of these services, build at least 60 to 90 days into your purchase contract and stay in weekly contact with the servicer. Escalate to a supervisor if the 45-day deadline passes without movement.

The policy shift that could blow this market open

Everything discussed so far applies only to government-backed loans: FHA, VA, and USDA. Conventional mortgages backed by Fannie Mae and Freddie Mac, which account for the majority of American home loans, are not assumable. A due-on-sale clause requires the full balance to be repaid when the property changes hands.

That could change. In November 2025, FHFA Director Bill Pulte posted on X that "at Fannie and Freddie, we are evaluating how to do assumable or portable mortgages in a safe and sound manner." He followed up days later: "We are actively evaluating portable mortgages." Portable mortgages would go even further than assumptions, allowing a homeowner to transfer their existing loan terms to a new property when they move.

No policy change has been implemented as of April 2026. But the signal matters. If Fannie and Freddie expand assumption eligibility to conventional loans, the addressable market goes from roughly 6 million homes to tens of millions. The housing lock-in effect, which the National Bureau of Economic Research estimated has reduced mobility by 16% and destroyed $20 billion in economic value, would begin to unwind.

The industry response to Pulte's announcement has been cautious. An op-ed on HousingWire argued that retroactive assumability could "cost MBS investors hundreds of billions" and potentially derail GSE IPOs. The mortgage-backed securities market depends on predictable cash flows; if millions of borrowers could transfer their below-market loans to new buyers, the math on those securities changes substantially. The Urban Institute's Goodman has noted that assumable mortgages "would need considerable policy accommodation to be an attractive option" at scale.

In other words: don't count on conventional loans becoming assumable anytime soon. But if you're buying a home with an FHA or VA loan today, the assumption feature is a built-in benefit that could become significantly more valuable over the next few years, especially if rates stay above 6%.

In 2023, fewer than 6,000 people did this. The number is growing fast.

The numbers are stark. Six million homes with assumable mortgages below 5%. Roughly 6,000 completed assumptions in 2023 (the most recent full-year data available). A 139% growth rate from the prior year that still leaves the vast majority of opportunity untouched. Both FHA and VA were on track to surpass 5,000 assumptions each in 2024, according to Mortgage Professional America, suggesting the total has roughly doubled since 2023. The gap between what's possible and what's happening is almost entirely a discovery and infrastructure problem, and the platforms, fee adjustments, and policy discussions of the last 18 months are all aimed at closing it.

Start on Roam, Assumable.io, or AssumeList. Ask every listing agent you talk to about the seller's loan type. Run the blended rate math before falling in love with a 2.75% headline number. Budget for 60 to 90 days of processing, not 30. And read our full guide to the mechanics before making an offer.

The 30-year fixed is sitting at 6.3% today. Somewhere in your market, there's a home with a 2.75% mortgage attached to it, and neither the seller nor their agent knows it's there. Now you know how to find it.
