Rate Lock

Mortgage term definition

Definition

A lender's guarantee that a specific interest rate will be held for a set period, protecting the borrower from rate increases during the loan processing period. Standard rate locks are 30-60 days and are typically free. Extended locks (75-120 days) may carry a small fee. If rates drop during the lock period, some lenders offer float-down options that allow you to take advantage of the lower rate for a fee.
