About 12 years ago I owned three rental houses in Columbus Ohio. One tenant asked if they could enter into a 5 year purchase contract with me. I believe in Ohio it was called a Land Contract. We agreed on the rent, additional payment options towards the equity, and an increasing vesting in the appreciation of the property based on his rent payments. We also agreed on a base purchase price with an option for me to increase the price depending on changes in real estate values (if they rose higher than anticipated).
He did this because his credit wasn't good enough to qualify for a loan and he didn't have money for a down payment. I benefitted because I still received rent and some equity appreciation while he was able to build equity in order to qualify for his loan. In the end I think he completed buying the home in 3 years rather than 5. There was a condition that if he couldn't purchase outright by the end of 5 years, he would receive his Payments towards equity back but would not receive any equity Vesting from appreciation.
I don't know if many people would do this but I liked the guy and wanted to help out and since the house was in a lower income area I feel I sold the house to him for a better price than if I sold to a traditional buyer.
