My brother is fixing up a house in Oklahoma. He plans to rent it when it’s fixed up. He needs money to fix up the house. He wants me to loan him the money, but frankly I cannot rely on him to pay me back. Does it make sense for me to file a lien in this kind of situation? Can the lien specify that the tenant will pay rent to me until the loan is paid off? Thanks in advance for any advice or direction you can provide.
