Rate Lock
A guarantee from your lender that your mortgage interest rate will not change for a specified period, typically 30 to 60 days, while your loan is processed. Rate locks protect you from market fluctuations. Longer locks may cost slightly more. If your loan does not close before the lock expires, you may need to pay to extend it or accept the current market rate. Lock your rate when you find a rate you are comfortable with.
Why It Matters
Rate Lock is a concept every mortgage borrower should understand before signing loan documents. The terms of your mortgage — including factors like rate lock — directly determine your monthly payment, total interest paid, and financial flexibility for the next 15-30 years. Taking time to understand these terms puts you in a stronger negotiating position with lenders.
When evaluating loan offers, ask your lender to explain how rate lock affects your specific loan scenario. Get it in writing on your Loan Estimate form, and compare how different lenders handle rate lock — the differences can save or cost you thousands over the life of your mortgage.
Real-World Example
For a typical $300,000, 30-year mortgage at 6.5%, understanding rate lock can help you evaluate whether you're getting the best possible terms. Even small variations in loan terms translate to significant dollar amounts over 360 monthly payments.
Pro Tip
Before your loan closes, make sure you fully understand how rate lock works in your specific mortgage. Ask your loan officer to walk through it — they're required to explain every term on your Closing Disclosure.
