The best way to find a rent to own situation is to have your Realtor look for you in the Multiple Listing Service (MLS). We can do a search for a "possible lease/purchase" property. A good Realtor will also make phone calls for you to see if a property owner might consider a lease purchase, even if it's not listed that way. Finally, Realtors will network with other agents and their sphere to find possibilities that may not even be listed.
If you're not currently working with an agent and have questions, I'd be happy to talk with you.
All the best!
