An assumable loan is a loan in which a purchaser of a property has the option to take over the existing loan payments under the same terms as the original borrower. This can happen with certain types of loans, such as FHA or VA loans, which allow the buyer to assume the mortgage, potentially at a more favorable interest rate than current market rates.

Options like taking out a second mortgage (A), choosing a loan servicer (B), or selling the loan (D) do not describe assumable loans.
