The Decision Most Buyers Do Not Fully Understand Until It Is Too Late

A rate lock is your lender's commitment to hold a specific interest rate for a set period of time while your loan is being processed and your transaction moves toward closing. It is one of the most consequential decisions in the mortgage process and one of the least discussed until something goes wrong.

How Rate Locks Actually Work

Rate locks typically run for 15, 30, or 60 days depending on the lender, the loan program, and the specific circumstances of the transaction. The lock period needs to be long enough to cover the time between when you lock and when you close. If the transaction takes longer than the lock period the rate has to be extended which comes with a cost.

Mortgage rates can and do change daily. Sometimes they move multiple times in a single day in response to economic data releases, Federal Reserve communication, bond market activity, or geopolitical developments. The rate you see quoted on the morning you apply may not be the rate available by the afternoon.

If rates rise between your application and your closing a rate lock protects you. The rate you locked is the rate you get regardless of what the market does after the lock is in place. Without a lock you are exposed to whatever the market produces on the day your loan is ready to close.

What Happens When Rates Fall After You Lock

One of the most common questions buyers ask after locking is what happens if rates drop after they commit to a specific number. As Judy Miller explains this depends entirely on the lock agreement you have with your lender.

Some lock agreements include a float-down option that allows you to capture a lower rate if the market improves by a certain threshold after your lock is in place. Not all lenders offer this and the terms vary significantly when they do. Understanding whether your lock agreement includes a float-down provision and what triggers it is part of the conversation every borrower should have with their lender at the time of locking.

When to Lock Is Not a One-Size-Fits-All Decision

The timing of when to lock your rate depends on three things that look different for every borrower. What rates are currently doing in the market and which direction they appear to be moving. How long your contract period is and how much time needs to be covered between now and closing. And your personal risk tolerance for exposure to rate movement during the transaction.

A borrower who cannot absorb any payment increase and is already at the top of their comfortable budget should lock as soon as the rate is available and the transaction supports it. A borrower with more financial flexibility who is in a falling rate environment might choose to float longer to capture a potential improvement. Neither approach is universally right and the right call depends on the specific situation.

Judy Miller walks every single one of her clients through this decision individually so there are no surprises at the closing table. The rate lock conversation is not an afterthought. It is a specific and personalized discussion about timing, risk, and the lock terms available for each borrower's specific transaction.
