Can I lock in my preapproval rate?

Yes, you can typically lock in your preapproval rate with a mortgage lender. When you get preapproved for a mortgage, the lender may offer you an interest rate that is valid for a certain period, typically ranging from 30 to 90 days. This rate lock period allows you to secure the interest rate offered to you at the time of preapproval, even if market interest rates fluctuate during the lock-in period.
