If you opt for Lock and Shop and follow its terms and conditions, this rate should not change. Your rate could change, if, for example, you ultimately choose a property at a higher price than the loan amount you listed on your pre-qualification application. But if your loan closes within the 90-day period (meaning that you complete the negotiation, inspection, and other home buying steps well before the 90-day period expires, typically within 30 to 60 days of entering into the Lock and Shop agreement.) If your mortgage loan does not close through no fault of your own, we will pay you $1,500 as part of our Lock & Shop promise.
