What Really Happens When You Lock a Mortgage Rate?

When you lock a mortgage rate, something happens behind the scenes that most homebuyers never see.

The lender makes a financial commitment in the mortgage market based on the expectation that your loan will close at that rate. That’s what allows the lender to protect you if rates rise before closing.

But then borrowers sometimes ask, “Rates went down. Why can’t I just change to the lower rate?”

The simple answer is that the lender already made that market commitment. A rate lock isn’t a reservation you can keep if rates rise and exchange if rates fall. It’s protection from market movement, and that protection works both ways.

Some lenders do offer an option to move to a lower rate after you’ve locked. But rates usually have to improve significantly before that option becomes available, and there’s often an additional fee. In other words, it’s not usually as simple as seeing a lower rate advertised online and asking the lender to substitute it.

So, rather than trying to predict where rates will go next, figure out what rate gives you a payment that works for your budget. When that rate is available, lock it and protect the payment you planned for.

And remember — it’s always okay to ask. We’re here to help you get home.
