When a home is sold, the seller may be able to transfer the mortgage to the new buyer. This means the mortgage is assumable. Lenders generally require a credit review of the new borrower and may charge a fee for the assumption. Some mortgages contain a due-on-sale clause, which means that the mortgage may not be transferable to a new buyer. Instead, the lender may make you pay the entire balance that is due when you sell the home. Assumability can help you attract buyers if you sell your home.
