There are many owners now a days that will enter a rent to buy situation mostly because the seller is having a hard time trying to sell their home or the buyers credit is very low. In these situations, the seller will require a large amount of deposit (about $3000-$5000) down.
I have found in the rent to own situation about 90 percent of the buyers NEVER end up buying the home and they end up loosing their deposit.
