What is a mortgage?

A mortgage is a loan used to buy a home. You repay the loan, with interest, over a set number of years. The property serves as collateral, meaning if you don't pay, the lender can take the home. Though you are a homeowner while paying the mortgage, it's only once the mortgage is paid off that you own the home "free and clear."

"Mortgage" can also refer to the legal document outlining the loan terms and permitting your lender to seize the home if you don't repay the loan as agreed. In some states, this document is called a deed of trust.
