Assumption of Mortgage
An assumption of mortgage allows a buyer to take over the seller’s existing loan. Learn benefits, risks, and lender requirements of assumable loans.
Definition
An assumption of mortgage occurs when a buyer takes over the seller’s existing home loan, including the interest rate and remaining balance, instead of obtaining a new mortgage. Assumable loans can save buyers money if the existing rate is lower than current market rates, and they may reduce closing costs. However, not all mortgages are assumable, government‑backed loans like FHA, VA, and USDA loans often are, while most conventional loans are not unless specifically permitted. Lenders typically require credit and income verification to approve the assumption. Buyers should also consider whether any difference between the purchase price and the loan balance must be covered with additional cash or secondary financing.
Why It Matters
An assumable loan at 3% is worth real money in a 6.5% market, often several hundred dollars a month. The obstacle is the equity gap: if the seller owes $310,000 on a house selling for $640,000, the buyer has to cover $330,000 with cash or a second loan. Sellers with VA financing have their own reason to care, because their entitlement stays tied to the loan unless a veteran buyer substitutes their own.
Examples
A 2021 FHA loan at 2.75% with a $290,000 balance passes to a buyer purchasing at $520,000. She covers $230,000 between cash and a second lien, and saves roughly $900 a month against new financing.
A servicer takes 90 days to process the assumption package. The parties extend closing twice, and the seller's planned rent-back has to be renegotiated.
A civilian buyer assumes a veteran's VA loan. The seller's entitlement stays attached until that loan is paid off, limiting what he can borrow on his next house.
Tips
Ask the seller for the note and look for a due-on-sale clause. FHA, VA and USDA loans are assumable with lender approval; nearly all conventional loans are not.
Start the assumption package the day the contract is signed and write a 60 to 90 day closing into the terms. Servicer assumption departments are slow and thinly staffed.
Price the second mortgage on the equity gap before you commit. A $250,000 second at 9% can wipe out the savings from a 3% first, and the blended rate is the number that matters.
