Pre-approved mortgage certificate (also called mortgage pre-approval certificate)
A pre-approved mortgage certificate confirms you're pre-approved by a lender to borrow a maximum amount at a guaranteed interest rate. The pre-approval certificate is subject to several conditions and expires after a limited time, usually up to 120 days. If the conditions are satisfied and your closing date is within that 120-day period, your guaranteed interest rate won't change. With a mortgage pre-approval certificate, you can shop for your new home with confidence.
