I've had people wanting to "buy" some property you have. Once they get you to agree to sell, then they ask if you can self-finance the sale (i.e., you become the bank and "sell" for nothing and they give you a monthly mortgage payment.) Sounds OK in theory, but you'd need a lot of paperwork/legal to vet the whole deal and you have no idea if the person can even pay until you spend even more on credit checks, etc. And If at some point they stop paying, you have to spend yet more on foreclosure and all the other stuff real banks have to deal with.
