Quick Answer

When your mortgage rate lock period expires before closing, you need to arrange an extension with your lender. If you do not extend, your locked rate expires and you will need to lock at the current market rate, which may be higher. Ask Patrick how rate locks and closing delays would work for your timeline.

The closing date moved, and now it sits past the day your rate lock dies. This is the exact moment where acting fast saves you money, Patriot Nation, because an expired lock is a whole new rate.

How rate lock extensions work

The term: an extension. Most lenders offer rate lock extensions if you need more time before closing.

The meaning: extensions typically cost a fee, which may be a flat amount or calculated based on how many extra days you need. Some lenders offer a one-time free extension of a few days, but this is not guaranteed.

The real-world play: the cost depends on current market conditions and the length of the extension. Contact your lender well before your lock expires to discuss options; waiting until the last day may limit your choices.

The cost of extending

The term: the extension fee. Extension fees vary by lender and market conditions.

The money: a typical 15-day extension might cost between 0.125% and 0.25% of the loan amount. Longer extensions or extensions during volatile markets can cost more. Always ask your lender for the exact cost before agreeing.

The real-world consequence: in some cases, your lender may offer to extend at no cost if the delay was caused by them rather than by you. If processing delays on the lender's side pushed closing past your lock expiration, they may waive the extension fee.

How to prevent lock expiration

The term: the buffer. The best way to handle an expiring lock is to prevent it from happening.

The meaning: choose a lock period that extends beyond your expected closing date. If your closing is 30 days away, consider a 45-day lock to give yourself a buffer. Longer locks cost more but provide peace of mind.

The real-world play: stay in close communication with your lender, real estate agent, and title company throughout the process. If any party identifies a potential delay, let your lender know immediately so they can help you arrange an extension or adjust the lock.

The bottom line

If your rate lock expires, you can extend it for a fee or accept the current market rate. Communicate early with your lender and choose a lock period with a buffer to avoid last-minute surprises. A delay does not have to cost you your rate if we move fast. Make it a great one.

Patrick's Take

"Rate lock extensions are common and manageable. The key is calling your lender as soon as you know you might need more time. Extending early is always cheaper than scrambling at the last minute."
