A good resource for finding a rental is American Management Property Solutions. They have properties all over the area, and I know they have one on Renwood in Kettering (3BR, 1BA w/fenced yard). That's technically Oakview Elem area, but you can probably open enroll to JFK if needed.
I have a four unit (each 2 bedroom) Apartment building for sale on Hadley in Kettering. You could buy it as owner occupied and build a lot of equity as the other 3 help pay the mortgage. Nice building. Each has central air and a garage with opener!
Rent to owns are few and far between and looking for one in a certain area is going to be like finding the needle in a hay stack when there is no needle in there. Rent to owns are a train wreck anyway and rarely do they work out and the renter buys the house so you end up wasting money. Just rent, fix your credit or what ever is preventing you from buying and buy when you can and forget the rent to fail deals.
