For a U.S. News article, I'm looking for mortgage experts who can talk about gift letters. I'll ask about who can give a gift, what information is needed in a gift letter and why it's required. I'll also ask about how much money counts as a gift that needs to be documented. The expert needs to have direct experience with this topic and be able to speak about it in-depth. Experts should be available for a 20-25 minute phone call by June 20. I don't accept background pitches, so please don't send them to me!
