One of the most commonly asked mortgage questions we hear at Broker Brothers Mortgage: what exactly is a rate lock and why does it matter?
Here is the simple answer.
A rate lock holds your interest rate in place while your loan closes. Once you lock in today's rate that rate is protected regardless of what the market does between now and your closing date.
Here is what you need to know.
It locks your rate: the rate you lock in today is the rate you close with. If rates move higher before closing you are protected from that increase.
Typical length: most rate locks run 30 to 60 days. That window is designed to cover the time from lock to closing on a standard transaction.
If rates rise: you are completely protected from the increase. Your locked rate holds.
If it expires: if your closing extends beyond the lock period an extension may be available but could come with a small fee. This is why staying on track with your closing timeline matters.
The best time to ask about locking your rate is once you are under contract. That is when the conversation should happen.
Lock terms and fees vary by lender and loan program so reach out and let's talk through what makes sense for your situation.
