There are roughly 6 million homes in the U.S. right now with an assumable mortgage and an interest rate below 5%, according to NPR reporting on AssumeList data from February 2026. For buyers staring down rates near 6%, that sounds like a lifeline. But here's the catch: if the home you're eyeing has a conventional loan, you almost certainly can't assume it.
No, the vast majority of conventional loans are not assumable. Fixed-rate conventional mortgages backed by Fannie Mae and Freddie Mac contain due-on-sale clauses that require full loan repayment when the property is sold or transferred. The Garn-St. Germain Act of 1982 created limited exceptions for family transfers, divorce, death, and trust transfers, but these do not apply to standard home purchases. Government-backed FHA, VA, and USDA loans are the assumable alternatives, representing roughly 23% of all outstanding U.S. mortgages.
Conventional loans aren't assumable. But that's not the end of the story. It's actually the beginning of a better one, if you know where to look.
Conventional mortgages, the most common loan type in America, are not assumable in a standard purchase transaction. No hedging, no "it depends." For the overwhelming majority of buyers and sellers, the answer is a flat no.
The reason comes down to one contractual provision: the due-on-sale clause. A due-on-sale clause means the lender can demand full repayment of the loan if the property changes hands. Both Fannie Mae and Freddie Mac require this clause in their loans, as outlined in the Fannie Mae Servicing Guide (D1-4.2-02).
As the Bipartisan Policy Center states plainly: "Conventional mortgages backed by Fannie Mae or Freddie Mac typically require that the full mortgage amount be paid off when the home is sold to a new owner."
This matters because conventional loans dominate the market. Fannie Mae and Freddie Mac loans comprise roughly 52% of all outstanding mortgage balances, approximately $6.5 trillion out of $12.94 trillion total, according to Federal Reserve Bank of New York data from June 2025. That's a massive share of the housing market where assumption simply isn't on the table.
Attorney Amy Loftsgordon of NOLO has noted that if a loan contract is silent on assumability, the loan is generally considered assumable in most states. But this is a rare edge case. Virtually all conventional loans originated after 1989 explicitly include due-on-sale clauses. Silence is almost never the situation.
That said, "not generally assumable" isn't the same as "never assumable." Federal law carves out a handful of specific situations where even a conventional loan with a due-on-sale clause can be transferred. Here's when that applies, and when it doesn't.
A few narrow pathways exist where conventional loan assumptions are legally permitted. Understanding them builds a complete picture, but be honest with yourself: these exceptions don't help most homebuyers in a standard purchase.
The Garn-St. Germain Depository Institutions Act of 1982 (12 U.S.C. §1701j-3) authorized lenders to enforce due-on-sale clauses nationally. But it also carved out specific situations where lenders cannot enforce them:
The critical framing: these are family and estate exceptions. They don't apply to a buyer purchasing a home from an unrelated seller on the open market. Several other exceptions exist under the Act, but they follow the same pattern of protecting family and estate transfers, not facilitating market sales.
Some smaller banks and credit unions hold loans on their own books rather than selling them to Fannie Mae or Freddie Mac. These portfolio lenders aren't bound by GSE rules and may allow assumptions on a case-by-case basis. This is uncommon and entirely at the lender's discretion. No buyer should build a strategy around it.
Conventional mortgages originated before the widespread adoption of due-on-sale clauses (generally pre-1989) may be assumable. These are now 35+ year-old loans and extremely rare in practice. Some adjustable-rate conventional mortgages historically included assumable provisions as well, though even when assumable, the rate adjusts, so the savings advantage may be minimal compared to government-backed fixed-rate assumptions.

Prior to 1982, some states' laws prevented lenders from exercising due-on-sale clauses, and assumable mortgages were much more common. States like Michigan, New Mexico, and Utah even had brief "window periods" where state law overrode federal due-on-sale enforcement. But modern conventional loans are never silent on this issue.
So if conventional loans are almost never assumable, why? It's not arbitrary. The due-on-sale clause exists for a very specific financial reason, and understanding it helps explain why government-backed loans work differently.
The financial logic behind due-on-sale clauses is straightforward once you see the math from the lender's perspective.
A lender holding a mortgage at 3% in a market where new loans originate at 6% is losing money on every dollar of that loan relative to current opportunity. If a new buyer steps into that 3% loan, the lender stays locked into below-market returns. Lenders want the loan paid off at sale so they can redeploy capital at current rates.
The numbers tell the story. According to the Bipartisan Policy Center (Q3 2025 data): 20% of outstanding mortgages have an interest rate below 3%, and the average rate on all outstanding mortgages is 4.4%. The average rate on a new mortgage was 6.16% as of January 8, 2026. On a $400,000 loan, that gap between 4.4% and 6.16% equals roughly $350/month, or $125,700 over 30 years.
Most conventional loans don't sit on a single lender's books. They're securitized: bundled into mortgage-backed securities (MBS) and sold to investors through Fannie Mae and Freddie Mac. Those investors bought bonds expecting certain prepayment patterns. Allowing assumptions would disrupt those expectations entirely.
As CNN has reported: "Portable mortgages could disrupt the engine powering the US housing market: mortgage-backed securities. If homeowners can take their loans with them when they move, fewer loans will be paid off early, which means more risk for investors, who might demand higher interest rates to compensate."
Before the Garn-St. Germain Act of 1982, the conflict between state laws and lender interests created chaos during the S&L crisis. Rising rates meant lenders were hemorrhaging money on old, low-rate loans they couldn't call due. The Act resolved this by giving lenders enforcement rights nationally while preserving the family and estate exceptions.
The financial incentives are clear. Conventional lenders lose money on assumptions, so they don't allow them. But the government made a different choice for FHA, VA, and USDA loans. And that's where the door is open.
The government designed FHA, VA, and USDA loans with assumability built in from day one. In a market where conventional assumptions aren't an option, these loans represent a massive, and massively underused, opportunity.
Of the nearly 52 million outstanding mortgages, about 23% are federally backed and eligible for assumption, according to the Bipartisan Policy Center. Government-backed loans account for 19% of outstanding balances, or $2.5 trillion of the $12.94 trillion total (Federal Reserve Bank of New York). And roughly 6 million homes currently have both an assumable mortgage and a rate below 5%.
From 2022 to 2023, the number of mortgage assumptions grew by 139%. The market is real, it's growing, and the savings are substantial.
Any buyer who meets the lender's creditworthiness standards can assume an FHA loan. You don't need any special status. The typical minimum credit score is 580 to 620. FHA loans represent about 12% of outstanding mortgage balances, and the buyer assumes the existing rate, remaining term, and balance.
Here's a common misconception: you don't need to be a veteran to assume a VA loan. Anyone who qualifies with the lender can take over the mortgage. One important seller consideration: if a non-veteran assumes the loan, the seller's VA entitlement stays tied to that loan until it's paid off. This is a real factor in negotiations. VA loans represent about 8% of outstanding mortgage balances.
USDA loans are assumable, but rates may reset to current USDA rates unless transferred between family members. The property must remain in an eligible rural area. It's a smaller share of the market but still a viable option in qualifying locations.
This is where the numbers speak for themselves.

Laurie Goodman of the Urban Institute has noted that assumable mortgages primarily benefit buyers with significant cash: "You can get a good deal if you have a lot of cash to put down." The down payment can be larger on an assumption because you're covering the seller's built-up equity. That's real. But it's also addressable through second liens, gap financing, or targeting homes where the equity gap is manageable.
So how do you actually find one of these homes? The process is more straightforward than most people expect.
Finding an assumable mortgage used to require guesswork and cold calls to loan servicers. Platforms like Assumable.io now track over 7 million FHA and VA assumable mortgage homes across all 50 states and more than 6,500 cities, making the search concrete and data-driven.

One more question keeps coming up: could conventional loans become assumable someday? It's no longer just hypothetical.
For the first time, the people who control the rules are publicly discussing a change.
In November 2025, FHFA Director Bill Pulte publicly stated: "At Fannie and Freddie, we are evaluating how to do assumable or portable mortgages, in a safe and sound manner." This is the first time a sitting FHFA director has explicitly opened this conversation.
The Groundwork Collaborative, in a paper co-authored by Bharat Ramamurti (former deputy director of the White House National Economic Council), argues that making conventional mortgages assumable would help break the rate-lock gridlock that's frozen housing inventory.
Any policy shift faces significant headwinds:
ConcernWhy It MattersMBS disruptionFewer early payoffs mean more risk for investors, potentially pushing rates higher for everyoneDown payment barrierAssumptions require larger down payments to cover seller equity, potentially excluding first-time buyers with limited savingsRetroactivityExisting Fannie/Freddie securities can't be changed retroactively; any new policy would likely apply only to new originations
This is being discussed at the highest levels. It may happen. It may not. But you don't need to wait for a policy change to benefit from assumption. Millions of assumable loans are already out there.
You came here wondering whether you could assume a conventional loan. The answer is no, with only the narrowest of family and estate exceptions. But the search itself led you to something more valuable: millions of government-backed FHA, VA, and USDA loans that were designed to be assumed, carrying rates that could save you over $1,187 per month compared to what you'd pay today.
The door to conventional assumption is closed for now. But a different door, to lower rates, real savings, and a smarter path to homeownership, has been open this whole time. Search assumable homes near you on Assumable.io. See the rate, the savings, and what's possible, all in one place.
