Mortgages are legal arrangements whereby a bank or lender lends an amount of money to a buyer to help the buyer buy a home. There are many different types of mortgages, but almost all mortgages are divided into two types: those that pay interest and those that pay a portion of the interest back each month. A mortgage pays interest on a monthly basis with a maximum interest rate of 3.5%.
