What is APR?
A tool used to compare loans across different lenders is the Annual Percentage Rate (APR). The Federal Truth in Lending law requires mortgage companies to disclose the APR when they advertise a rate. It is designed to represent the true cost of the loan to the borrower, expressed in the form of a yearly rate. The purpose is to prevent lenders from hiding fees and upfront costs behind low advertised interest rates.

Lock in Your Rate
A lock in, also called a rate lock or rate commitment, is a lender's promise to hold a certain interest rate and a certain number of points for you, usually for a specified period of time, while your loan application is processed. Depending upon the lender, you may be able to lock in the interest rate and number of points that you will be charged when you file your application, during processing of the loan, when the loan is approved, or later.
