What makes you say they are not qualified to purchase? Check out 21st’s CASH Program where they will help you acquire new homes at wholesale prices and wrap the home cost and setup costs (site prep, delivery, etc.) into a loan for the end buyer. They offer credit score flexibility for them and attractive rates and terms. You can almost certainly offer them a new home to purchase for cheaper than you otherwise would be able to profitably rent it to them (assuming you are paying full retail for the home).
Full disclosure: I have not yet gone through the entire process of getting setup with them but I have begun the investigation into it, and it appears straight forward.
