The Lock and Shop program will lock interest rates for up to 90 days on the purchase of a primary residence. The Lock and Shop program is only available with Homebuyer Advantage. Property address must be identified within 60 days after the lock date, or the loan's pricing will return to the current market rate with the option to lock again. A one-time rate float-down option is available after the property address is identified. The float-down option is valid for 30 days and may not exceed the original lock expiration date. If the residence type changes to a second home or investment property, the rate float-down option will no longer be available. Rate extensions are available after the property is identified and fees may apply.
