What Is a Lock-In?
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. (Points are additional charges imposed by the lender that are usually prepaid by the consumer at settlement but can sometimes be financed by adding them to the mortgage amount. One point equals one percent of the loan amount.) 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.
A lock-in that is given when you apply for a loan may be useful because it’s likely to take your lender several weeks or longer to prepare, document, and evaluate your loan application. During that time, the cost of mortgages may change. But if your interest rate and points are locked in, you should be protected against increases while your application is processed. This protection could affect whether you can afford the mortgage. However, a locked-in rate could also prevent you from taking advantage of price decreases, unless your lender is willing to lock in a lower rate that becomes available during this period.
