With mortgage rates above 7% in October 2026, according to Freddie Mac, many buyers are looking for ways to get a lower rate. One option that has gained attention is an assumable mortgage, which lets you take over the seller’s existing loan, including its interest rate. If the seller locked in a rate of 3% or 4% a few years ago, that can mean hundreds of dollars in monthly savings. In this guide, you’ll learn how an assumable mortgage works, which loans qualify, what it costs, and the pros and cons for buyers and sellers.
What Is an Assumable Mortgage?
An assumable mortgage is a home loan that a buyer can take over from the seller, keeping the same interest rate, remaining balance, and repayment schedule. Instead of getting a brand-new mortgage at today’s rates, the buyer “steps into” the seller’s loan.
The lender or servicer must approve the assumption, and the buyer usually has to qualify much like they would for a new loan.
Which Loans Are Assumable?
| Loan type | Assumable? | Key conditions |
|---|---|---|
| FHA | Yes | Buyer must qualify and live in the home |
| VA | Yes | Buyer must qualify; buyer doesn’t need to be a veteran |
| USDA | Yes | Buyer and property must still meet USDA rules |
| Conventional | Rarely | Most include a “due-on-sale” clause that prevents assumption |
Most conventional loans can’t be assumed in a normal sale, so in practice almost every assumable mortgage is an FHA, VA, or USDA loan. You can learn more about each program in our guides to FHA vs conventional loans, VA vs FHA loans, and USDA loan requirements.
How Much Can You Save? An Example
Imagine a seller who took out a $320,000, 30-year loan at 3% five years ago. Today, the remaining balance is about $285,000, with 25 years left, and the home sells for $450,000.
| Assume seller’s loan | New loan at 7.2% | |
|---|---|---|
| Loan amount | About $285,000 | $285,000 |
| Interest rate | 3.0% | 7.2% |
| Remaining term | 25 years | 30 years |
| Monthly payment (P&I) | About $1,349 | About $1,935 |
By assuming the loan, the buyer would pay about $586 less per month, and the loan would be paid off five years sooner. Figures are illustrative; actual savings depend on the seller’s rate and balance.
The Big Catch: The Equity Gap
The buyer takes over only the remaining loan balance, not the full price of the home. In the example above:
- Home price: $450,000
- Loan assumed: $285,000
- Amount the buyer must cover: $165,000
This difference, often called the equity gap, is the biggest obstacle with an assumable mortgage. Buyers usually cover it with:
- Cash savings
- A second mortgage or home equity loan from another lender, usually at a higher rate than the assumed loan. Our guide on cash-out refinance vs HELOC explains how home equity loans work.
- A combination of both
If you need a large second loan at a high rate, it can reduce or even cancel out the savings, so run the numbers on both loans together.
How the Assumption Process Works
- Confirm the loan is assumable. Ask the seller to get written confirmation and the assumption package from their servicer.
- Make an offer that states it depends on approval of the assumption.
- Apply with the servicer. You’ll submit income, asset, and credit documents, similar to a new loan application. Lenders review your credit and debt-to-income ratio.
- Arrange financing for the equity gap, if needed.
- Wait for approval. Assumptions often take longer than regular loans, sometimes 45 to 90 days or more, because servicers handle them less often.
- Close. The seller should receive a release of liability, so they’re no longer responsible for the loan.
What Does an Assumable Mortgage Cost?
Assumptions are often cheaper than a new loan, but they’re not free:
- FHA assumption fee: servicers can charge a processing fee, which HUD caps at $1,800.
- VA funding fee: the VA charges a funding fee of 0.5% of the loan balance on assumptions.
- Other closing costs: title, recording, and escrow costs still apply. See our guide to closing costs.
- Costs of a second loan, if you need one to cover the equity gap.
Also keep in mind that on an FHA loan, the existing mortgage insurance usually stays in place after the assumption. Our guide on how to avoid PMI explains how FHA mortgage insurance differs from conventional PMI.
VA Assumptions: What Sellers Should Know
Anyone can assume a VA loan if they qualify, even if they’re not a veteran. But for the seller, this has an important consequence: if the buyer isn’t a veteran who can substitute their own VA entitlement, part of the seller’s VA entitlement stays tied to the loan until it’s paid off. That can limit the seller’s ability to use a VA loan again in the future.
Veteran sellers should ask the servicer about substitution of entitlement and always require a formal release of liability before closing.
Pros and Cons of an Assumable Mortgage
Pros for buyers
- Lower interest rate than today’s market
- Lower monthly payment
- Fewer years left to pay off the loan
- Lower closing costs in many cases
- Often no new appraisal required by the servicer
Cons for buyers
- Large equity gap to cover with cash or a second loan
- Slower approval process
- Few homes have assumable loans
- FHA mortgage insurance usually continues
- You still need to qualify
For sellers
- An assumable mortgage can make your home more attractive and help it sell in a high-rate market
- But the process takes longer, and VA sellers may lose part of their entitlement unless the buyer substitutes theirs
How to Find a Home With an Assumable Mortgage
- Ask your real estate agent to search listings for “assumable” in the description.
- Look for homes bought in 2020 to 2022 with FHA, VA, or USDA financing, when rates were lowest.
- Ask sellers directly whether their loan is assumable; some don’t realize it.
- Check with the servicer before making an offer rather than relying only on the listing.
A Note From José María
I’m José María, and I created Finanzasclave to explain mortgage and home-buying decisions in plain English. When I researched this guide, the low rates on assumable loans looked almost too good to be true, and the equity gap is the reason. That’s why I included an example showing how much cash a buyer may need. My advice: an assumable mortgage can be a great deal, but only if you can cover the gap without taking on an expensive second loan. Compare the full cost of both loans before you commit.
Frequently Asked Questions
Can I assume a conventional mortgage?
Usually not. Most conventional loans include a due-on-sale clause, which requires the loan to be paid off when the home is sold. Exceptions are rare.
Do I need good credit to assume a mortgage?
Yes, in most cases. The servicer reviews your credit, income, and debts, much like a new loan application.
Can a non-veteran assume a VA loan?
Yes, if they qualify and the servicer approves. However, the seller’s VA entitlement may remain tied to the loan.
How long does a mortgage assumption take?
It varies by servicer, but assumptions often take longer than regular purchases, commonly 45 to 90 days or more.
Is an assumable mortgage worth it?
It can be, especially when the seller’s rate is much lower than current rates and you have enough cash for the equity gap. If you’d need a large, high-rate second loan, the savings may be much smaller.
Final Thoughts
An assumable mortgage can be one of the best ways to get a low interest rate in today’s market, but it’s not a simple shortcut. You’ll need to qualify, wait longer for approval, and cover the difference between the loan balance and the home price. If the numbers work, the monthly savings can be significant for years to come. Before you make an offer, confirm the loan is assumable, ask the servicer for its requirements, and compare the total cost with a new mortgage.
