The purpose of this letter is to document that the money does not need to be repaid as well as the donor's name, contract information, and relationship to you.The person who gave you the money must write and sign the gift letter as well as provide their personal information. The letter also must indicate that the money is a gift and that there is no expectation of repayment. A gift letter for a mortgage is proof to the lender that money you've been given for your home purchase is a gift, not a loan to be repaid. What should you include in a gift letter? Gift funds may not be contributed from any source that has an interest in the sale of the property (seller, builder, real estate agent, etc.). Like the VA loan program, gift money can be used to pay closing costs. While it's possible that no one claims on it, it's best to prepare for any legal issues in the future. Mortgage Gift letter is what the donor of the gift writes to the lender stating that he has offered a gift of money to the home buyer.
