When you are ready, any local REALTOR( should be able to pull up that type of listing in the MLS to show to you.
I would suggest you get pre-qualified in some way with a local lender before you move into a home that you wish to "rent to own", unless that home is seller financed. That way, you can know ahead of time if you will even qualify to purchase the home. You definitely want to know all that's involved before signing a lease on a property like what you are seeking and any qualified REALTOR should be able to help get you those answers.
I hope this helps and good luck with your search :)
