<prompt> Human: Hello PF,My father is planning to purchase a mobile home for about 40k. What things can he do to ensure the sale and everything is legitimate? The seller is from out of state and my father has yet to meet him in person. It doesnt necessarily raise a red flag for me, but it is still a significant amount of money that Id like to do all due diligence to make sure this is not some sort of scam.  <response>: Just like purchasing a car, make sure the title is signed over to your dad
