Should I lock my interest rate?

What locking means: Locking your rate protects you from rate increases before closing. A rate lock holds a specific interest rate and terms for a set period, usually long enough to carry you from application through settlement, so the rate you were quoted is the rate you get.

It turns the most volatile part of the financing into a known quantity, which is exactly why so many buyers choose to lock.

When locking makes sense: If rates are volatile or rising, locking is generally advisable. A rising market is precisely when the protection has value, because waiting can cost you more every week the rate moves up. Buyers who lock in a rising market are protecting the deal they can already see.

Most lenders will tell you plainly when the environment favors locking, and that advice is usually worth following.

When floating makes sense: If rates are trending down, you might choose to float the rate, hoping to lock later at a better number. The upside is a lower payment; the downside is risk, because rates could just as easily move up while you wait, and the savings could evaporate.

Floating is a bet on the direction of the market, and it is a bet that needs a clear exit plan: a date or a rate at which you lock and stop watching.

Lock terms and timing: Locks come in set terms tied to your expected closing date, and the right length depends on where you are in the process. Lock too early and the term may expire before closing; lock too late and you lose the protection during the very window you needed it.

Your lender will align the lock with your contract and estimated closing date so the coverage lasts until settlement.

Who decides: A trusted lender will advise you on the best timing, because they watch the market daily and know the particulars of your loan. The decision is ultimately yours, but it should be informed by an honest read of where rates are and how much time remains before closing.
