Should You Lock Your Mortgage Rate, or Wait?

Buyers ask me this almost every week: should I lock my rate now, or wait to see if it drops? I get why. Nobody wants to lock in a rate and then watch it fall a week later. But waiting has a real cost too. Here is how to think about it without guessing.
What a rate lock actually does
A rate lock holds your quoted interest rate for a set window while your loan moves through underwriting and closes, commonly 30 to 60 days. Once you lock, your rate does not move even if the market does, up or down, for the length of that window.
Without a lock, your rate can float right up until closing. That means it can also float down. That is the whole tradeoff in one sentence.
Why "just wait for the Fed to cut rates" is not the right question
A lot of buyers wait for a Federal Reserve rate cut, assuming that will pull mortgage rates down with it. It is not that direct. Mortgage rates track the 10-year Treasury yield more closely than they track the Fed's short-term policy rate. The Fed and mortgage rates can move in different directions in the same month. If you are watching for a signal, the 10-year Treasury is the more useful one to follow, not the Fed announcement.
Freddie Mac publishes the average 30-year fixed rate every week (the Primary Mortgage Market Survey, or PMMS). It is a solid market reference point for where rates actually sit today, not a prediction of where they are headed.
"Date the rate, marry the house"
This is the phrase I use with buyers, and it is not just a saying. If your rate does drop meaningfully after you close, you are not stuck. A refinance later can capture the lower rate. But if you pass on a house waiting for a rate that never comes, that house is gone, and you do not get it back.
Nobody can tell you with certainty where rates go next. So the decision is not really about predicting the market. It is about whether the payment works for you today, on the house you actually want.
A simple way to decide
- If the payment works at today's rate and you have a home under contract, lock it. You remove the guessing and know your number.
- If you are still shopping and months out from an offer, there is nothing to lock yet. Just check the current PMMS average so you are not budgeting off an old number.
- If rates do move down after you close, ask about refinancing later. That is the safety valve, not waiting to buy.
Get a real number, not a guess
The only way to know what a lock actually gets you is to see your real rate, on your real file, today. Call North Florida Mortgage at 904-389-4635 and we will walk through your numbers and whether locking makes sense for your timeline.
