When mortgage rates climb, some buyers discover they can inherit the seller's existing loan instead of getting a new one at today's higher rate. This is called assuming a mortgage, and it's available on FHA, VA, and USDA loans—not conventional. If the seller locked in at 3.5% three years ago and today's market sits at 7%, assumption can save hundreds a month. These figures are illustrative; rates and products are subject to change and this is not a commitment to lend.
Which loans are assumable
Only government-backed mortgages allow assumption. FHA and USDA loans are assumable by any qualified buyer. VA loans are also assumable, but if a non-veteran assumes a VA loan, the seller's VA entitlement stays tied to that property until the loan is paid off—which can limit the veteran's ability to use VA benefits again. Conventional loans from Fannie Mae and Freddie Mac are not assumable under normal circumstances.
How the process works
The buyer applies directly with the servicer managing the seller's loan. The servicer underwrites the buyer just as if it were a new loan: credit, income, debt-to-income, and reserves are all reviewed. Approval is not automatic. Processing timelines vary—some servicers take 60 to 90 days—so build that into your purchase contract. The seller remains liable unless the servicer grants a full release, which most do upon buyer approval.
The equity-gap problem
Assumption only covers the existing loan balance. If the seller owes two hundred thousand and the purchase price is four hundred thousand, the buyer must bring two hundred thousand in cash or arrange separate financing for the gap. Some buyers use a second mortgage or home-equity line of credit, but those typically carry higher rates and shorter terms, which can erase much of the monthly-payment advantage. Cash-heavy buyers benefit most.
When assumption makes sense
Assumption is worth exploring when the seller's rate is materially lower than current market rates and the buyer can cover the equity gap affordably. Always compare total monthly cost—including any second lien—against a new first mortgage at today's rates. Factor in the servicer's assumption fee, typically five hundred to one thousand dollars, and any lender charges on gap financing. Run the numbers on both paths using realistic figures.
The Alliance take
Assumption is a tool, not a magic bullet. It requires lender approval, a plan for the equity gap, and patience with servicer timelines. If you're evaluating a property with an assumable loan, model both scenarios: assumption plus gap financing versus a new loan at current rates. Sometimes the simplicity and speed of a new conventional loan outweigh the rate advantage. We can walk you through the comparison and connect you with servicers experienced in assumptions.
