A seller closed in 2021 at 3.0%. You are shopping at 6.55%. On a $300,000 balance that gap is worth about $640 a month for as long as the loan runs — and on an FHA or VA loan, it can legally transfer to you.
You’ll learn which loans are assumable, what the process involves, the equity gap that kills most of these deals, and the entitlement trap that VA sellers need to understand before agreeing.
Which Loans Can Be Assumed
Assumption means the buyer takes over the seller’s existing mortgage — same rate, same remaining term, same balance — rather than originating a new loan.
| Loan type | Assumable? |
|---|---|
| FHA | Yes, with lender approval and buyer qualification |
| VA | Yes, and the buyer need not be a veteran |
| USDA | Yes, subject to program conditions |
| Conventional | Almost never — the due-on-sale clause requires full repayment |
That last row explains why this is a niche opportunity rather than a general strategy: most outstanding mortgages are conventional and simply cannot be transferred. The pool is FHA, VA and USDA loans originated during the low-rate years.
The Equity Gap
Here is what stops most of these deals, and it is arithmetic rather than paperwork.
You assume the loan balance, not the purchase price. If the home sells for $450,000 and the remaining balance is $300,000, you must bring the $150,000 difference — in cash, or through a second loan.
| Purchase price | Assumed balance | Cash gap |
|---|---|---|
| $450,000 | $300,000 | $150,000 |
| $450,000 | $400,000 | $50,000 |
| $350,000 | $320,000 | $30,000 |
The paradox is unavoidable: the more the home has appreciated since the seller bought at that lovely rate, the larger the cash gap becomes. The best assumptions are usually recent purchases with modest appreciation, not the 2021 vintage everyone is hunting for.
A second mortgage can cover the gap, but it will be priced at today’s rates, so blend the two before assuming you have won. A $300,000 loan at 3% plus a $150,000 second at 8% produces a blended cost well above the headline. Model the combination in our mortgage calculator before committing.
How the Process Works
You still qualify. Credit, income and debt-to-income are all underwritten — assumption transfers the rate, not the approval. Expect the same documentation as a normal application.
The servicer, not the original lender, approves it, and this is where timelines suffer. Assumptions are uncommon, servicer teams are small, and 60 to 90 days is realistic where a standard purchase would take 30 to 45. Build that into the contract rather than discovering it later.
Costs are lower, though. There is an assumption fee, typically modest, and no origination on a new loan. Appraisal requirements are often lighter since the loan amount is already fixed — which also means an appraisal coming in low is a smaller risk than in a conventional purchase.
The VA Entitlement Trap
This one matters enormously and is routinely missed by sellers.
When a veteran’s VA loan is assumed by a buyer who is not a veteran, or by one who does not substitute their own entitlement, the seller’s entitlement stays tied to that property — potentially for decades. Until the loan is paid off, that portion of their entitlement is unavailable for their next VA purchase.
A veteran who sells this way to help a buyer capture a 3% rate may find they cannot use their own benefit on the home they move into. The fix is substitution of entitlement, which requires a buyer who is themselves an eligible veteran willing to substitute. Any veteran seller considering an assumption should confirm the entitlement consequences in writing before agreeing — our guide to how VA underwriting works covers the wider program.
Finding One
Assumable loans are not indexed anywhere reliable, so this is legwork. Ask your agent to check the loan type on listings of interest — it is often discoverable from public records. Homes bought between roughly 2020 and 2022 with FHA or VA financing are the target set, and sellers frequently do not know their loan is assumable until asked.
Treat it as a bonus rather than a strategy. The combination of an assumable loan, a manageable equity gap and a seller willing to wait 90 days is genuinely rare. Meanwhile, check where rates actually sit on our daily rates page, since the gap you are chasing narrows if rates fall.
The bottom line
- FHA, VA and USDA loans are assumable; conventional loans effectively are not.
- The buyer takes over the balance, not the price — the difference is due in cash or a second loan.
- Buyers still qualify on credit, income and DTI; only the rate transfers.
- Servicer processing commonly takes 60 to 90 days, not the usual 30 to 45.
- A VA seller can have their entitlement tied up for years unless an eligible veteran substitutes theirs.
Frequently Asked Questions
What is an assumable mortgage?
A loan a buyer can take over from the seller at the original rate, term and balance, instead of originating a new mortgage. FHA, VA and USDA loans generally allow it.
Do I have to be a veteran to assume a VA loan?
No. A non-veteran buyer can assume a VA loan with servicer approval, but the seller’s entitlement then remains tied to the property until the loan is repaid.
How do I pay the difference between the price and the loan balance?
In cash, or with a second mortgage at current rates. Blend the two rates before assuming the assumption is cheaper than a new loan.
How long does a mortgage assumption take?
Commonly 60 to 90 days, since servicers process relatively few of them. Build the longer timeline into the purchase contract.
