A gift letter for a mortgage shows your lender that you don't need to repay gift money toward your down payment. The letter must explain who is gifting the money, where the donor's funds are coming from and the relationship between the donor and the recipient.Pin down the specifics of the property in question. Clearly state the property's address, ensuring there's no ambiguity about where the gift funds are intended. 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. If someone is giving you a monetary gift to help you meet mortgage lending requirements, follow these three steps. 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.). If you use your gift money for your down payment, you donor must write a gift letter to the lender explaining clearly that the money is a gift and not a loan. 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. The lender will need a "gift letter" from the donor to make sure your down payment help has no strings attached.
