Rent to own is very simple... In basic terms, a purchase price is agreed on upfront, along with rent and a durations (1yr, 3 yrs). Then usually there is option money paid by tenant or buyer... Option money usually is what allows you to lock in the price ahead of time, but also give you the option to "walk away" if the house ends up being worth less at the end of your lease duration. Option money usually goes towards purchase price if buyer follows through and buys home, and is forfeited if buyer walks away from deal. It is a great tool for both sides, as it allows a landlord the benefits of leasing with the knowledge the tenant intends to buy the home, and it allows the buyer to lock in a price early, and take a "wait and see" attitude about the housing market. You can complicate things by adding rental credits each month, but what I have mentioned is a basic lease option or rent to own situation. Goodluck!
