Should you lock in a mortgage rate — and if so, when?
Mortgage rates change daily, meaning the mortgage interest rate you see when you first apply for your mortgage preapproval or approval may not be the same rate you end up with at closing. That’s why mortgage rate locks exist. Simply put, a mortgage rate lock freezes your interest rate until the loan closes and protects you from rising rates.
Although the Federal Reserve has been cutting the federal funds rate, mortgage rates have remained relatively high. Rates will probably go down in 2025, but the shifts will be gradual. Here’s everything borrowers should know about mortgage rate locks, if now is a good time to lock in your rate, and whether a lock makes financial sense for you.

What is a mortgage rate lock?
A mortgage rate lock is a commitment from a lender guaranteeing that the interest rate on your home loan will remain the same until the day you close on the house — provided the mortgage closes within the specified time frame and there are no changes to your loan application. With a mortgage rate lock, the home buyer gets to keep the lower rate even if market rates go up.
However, if rates go down when you close on the mortgage loan, you could be stuck with a higher rate. A float-down option takes away that risk. Some mortgage lenders offer rate locks with float-down options, so you can still get a new rate if mortgage rates dip below your rate lock. It typically isn't free, though, and most lenders will charge you 0.5% to 1% of the loan amount. It will only make financial sense to exercise a float-down option if rates drop low enough to justify the cost.

When to lock in a mortgage rate
The answer to when you can lock in your rate depends on the mortgage lender. Typically, you can lock in a mortgage rate at any time after you’ve been approved for the home loan and up to five days before closing. A lender might include a rate lock in the Loan Estimate, which it provides within three days before closing. Some lenders allow you to lock in a rate at other times, such as when you are preapproved.
But with all of these options, when exactly should you lock in a rate? The short answer is: Pay attention to market dynamics.
If interest rates have been stable, locking in your rate early may not be necessary. If rates are falling and are likely to continue in that direction, you may want to wait a bit before locking the rate since you could get a better rate in a few weeks. However, if interest rates are rising, and you’re worried you won’t be able to afford your mortgage with a higher interest rate, it’s worth doing a mortgage rate lock as soon as possible.
Many thought mortgage rates would start falling as the Fed started cutting rates, but that hasn't been the case. In fact, many interest rates have been increasing, and since the presidential election results, it's unclear how the markets will respond in the long term. If you're unsure about whether to lock in a mortgage rate now or wait, talk to a loan officer about your options.

How long can you lock in a mortgage rate?
Depending on the lender, you can typically lock in a mortgage rate for 30, 45, or 60 days — sometimes even longer. As long as you close within the specified time frame, your mortgage rate won’t change. But if your rate lock expires before you close on the loan, you’ll have to pay a fee to extend the period of time. The interest rate lock extension fee is typically a percentage of your loan amount. The longer the extension, the higher the cost.

How to lock in a mortgage rate
A mortgage rate lock can be helpful if market rates are trending up before your closing date. Take the following steps to lock in your mortgage rate:
-
Shop around. Before locking in your mortgage rate, submit mortgage preapproval applications with at least three different mortgage lenders so you can compare potential offers. Besides interest rates, you’ll also want to compare things like down payment requirements, origination fees, rate lock periods, and float-down options.
-
Find a home and make an offer. While many lenders allow you to lock in the mortgage rate any time after you’ve been approved for the home loan and up to five days before closing, you may have to pay extra to extend the lock if the rate lock expires before your loan closes. So, it might be best to start house-hunting and make an offer on the home you want before locking in a rate.
-
Contact your lender. When you’re ready for a mortgage rate lock, reach out to your lender to select the mortgage rate lock period you want and fully understand your options.

Should I lock in my mortgage rate today?
We don’t have a crystal ball to tell you when mortgage rates will go down or whether it’s a good idea to lock in your mortgage rate today. Plus, rate predictions largely depend on who you ask. Experts at Fannie Mae and the Mortgage Bankers Association predict that the 30-year fixed mortgage rates will hover around 6% to 6.3% to end 2024.
Mortgage rates have been increasing over the last two months, and the current economic and political climate make it unclear how low rates will go in 2025. If you’re risk-averse and want to avoid any chance of your mortgage rate increasing, locking in your mortgage rate today may be the best option. Especially since it's unlikely rates will drop significantly by the end of 2024.
Note: The Mortgage Bankers Association and Fannie Mae may change their predictions to be even lower in their upcoming November forecasts.

Mortgage rate lock FAQs
What happens if you lock in a mortgage rate and it goes down?
If you’re locked in and mortgage rates fall, you’ll be stuck paying the higher rate unless your rate lock includes a float-down option. A float-down option lets you honor your locked-in rate or the current rate, whichever is lower. This option isn’t free, though. You can expect to pay between 0.5% to 1% of the loan amount when you use a float-down. For a $350,000 loan, that's $1,750 to $3,500.
Is it worth locking in mortgage rates?
Locking in your mortgage rate is typically worth it when rates are rising, and you want to protect yourself from paying a higher rate at closing. If mortgage rates increase after you’ve locked in the rate, you still get to keep your lower rate. If you want to buy before the end of 2024, locking in a rate could be a good idea. But rates should gradually decline in 2025, so if you're in no hurry, you may prefer to wait.
How much does it cost to lock a mortgage rate?
Lenders typically charge anywhere from 0.25% to 0.5% of your loan amount to lock in a mortgage rate. So, if you take out a $300,000 loan, you can expect to pay $750 to $1,500 for a mortgage rate lock.
