If you are interested in finding a property that offers that option, you should hire a buyer's agent to help you with this.

From the MLS listing, this home appears to be a short sale, it is subject to bank approval but it is not a bank owned property. In this case I don't think the owner would be able to do a rent to own but it is possible. I am an agent in Westerly, if you contact me I could call the other agent for you. This is a great time to buy for first time homebuyers for many reasons. I would be happy to work with you.
