In exchange for their financial support, partnering with investors who have money to invest but do not have the time or experience to locate and manage properties might provide invaluable information.One can purchase homes with little to no down payment by utilizing creative financing alternatives such as seller carryback financing, lease options, and subject-to transactions.
