First off, a big hug is in order. Second, your parents will need to provide a signed “Gift Letter” (your loan officer can give you one of these). You will also need to show three important things: availability, transfer, and receipt: Availability: A signed letter from your parents’ bank stating the account noted on the gift letter had sufficient funds to cover the amount of the gift.Transfer: A cashier’s check, drawn from your parents’ account, with your parents as remitters, with their account number (must match account number on the gift letter) noted on the check. Make a copy of the check before you deposit it.Receipt: Provide a copy of the deposit ticket and a printout from your bank showing the money made it into your account.
