Typically, someone listing their house for sale is not in a position to rent-to-own or simply wants to sell outright to a qualified buyer.
Those who are more likely to consider rent-to-own are those sellers whose houses are not selling the traditional way (i.e., their MLS listing is not getting the offers they need and their house is just sitting on the market for a long time) or someone marketing their home for rent and doesn't want to hold it as a long-term rental may consider rent-to-own.
Lastly, some of the people marketing their homes for sale by owner, may be more open to rent-to-own than a seller who has their home listed with a Realtor.
Then, for those who will consider rent-to-own, you will need a non-refundable down payment (typically a minimum of 3.5% of the purchase price of the home or $5,000, whichever is greater), have credit that can be repaired in less than 24 months and be in a position to get a bank loan during that time frame, and good income and job history, etc.
