Rate Locks Explained: Securing Your Interest Rate

When you’re getting a mortgage, interest rates can feel like they shift every time you check. A rate lock is one of the simplest ways to protect yourself from a sudden jump. Here’s how it works and why it matters.

What a rate lock is

A rate lock is an agreement between you and your lender that freezes your interest rate for a set stretch of time, usually 30, 45, or 60 days. Once it’s in place, your rate holds steady while you finish the loan process, even if the broader market moves against you.

Why they matter

The biggest benefit is protection. If rates climb while you’re under contract, your locked rate doesn’t budge. That stability also makes budgeting easier, since you already know your payment, and it takes a real source of stress off the table so you can focus on the house and the paperwork instead of watching the market.

How long a lock lasts

Locks come in standard windows, most commonly 30, 45, or 60 days. Which one makes sense depends on your timeline, current market conditions, and what your lender offers. A longer lock buys you more breathing room but usually costs a little more.

What happens if rates drop

Some lenders offer a float-down option that lets you grab a lower rate if the market improves during your lock period. Not everyone offers it, and it can carry an added cost, so it’s always worth asking before you assume you have it.

When to lock

A good rule of thumb is to lock once you’re under contract and confident in your closing timeline. It also makes sense to lock when rates are trending up and you’d rather have peace of mind than roll the dice. When in doubt, talk it through with your lender (hi, that’s me!), who can weigh the timing against your loan type and where the market sits.
