What does a rate lock mean?
Many borrowers do not want to be surprised at the close of the transaction with a rate which is higher than what was quoted at the beginning of the process. Hence, many borrowers ask that the lender commit or “lock” the initial rate quoted for a period of time sufficient to close the transaction. When a rate is “locked” the lender is being asked to guarantee the price of a commodity, the price of which changes daily (check out the daily changes in the bond market, which is a measure of the price of money on a daily basis). The longer the lock period, the riskier the position of the lender, hence the higher the loan price (points) charged the borrower.
