The seller of a home we like says assuming his mortgage would be a good deal for us. Would it?
It might well be a good deal, especially if the seller took out the mortgage in recent years when rates were lower.
"Assuming a mortgage" means the buyer takes over the existing interest rate and remaining repayment period.
This can be a great option if the seller's mortgage has an interest rate well below today's market (around 5.9'6.1 percent for a 30-year fixed as of early 2026). For example, if the current market rate is 6 percent and the assumable mortgage is 3'4 percent, it's often a very strong deal'potentially saving thousands in interest over time. If the existing mortgage is closer to 6 percent, you might save modestly on a 30-year term, but a new 15-year loan (now averaging 5.4'5.5 percent) could be better.
Another key consideration is the seller's equity. The seller will want to be paid for their built-up value in the property. A buyer must cover this equity gap in cash or with a separate loan.
Remember, when you assume a mortgage, you don't inherit the seller's credit rating. You must still apply and qualify under the lender's requirements.
Conventional lenders typically don't allow assumable mortgages due to due-on-sale clauses.
You can assume an FHA or VA loan in most cases, but you'll need to meet income, credit, and other standards (minimum credit scores often 580 to 620 depending on the loan).
Before proceeding, verify the loan isn't delinquent. Any back payments become your responsibility, and you may need to pay back payments or seek a loan modification.
Properly processed FHA/VA assumptions during a sale usually release the seller from future liability. However, for VA loans, the seller (if a veteran) may risk their VA entitlement. It could stay tied to the property unless the buyer is a veteran and substitutes his or her own, potentially limiting the seller's future VA loan options.
