It is always possible to set up a lease/buy option in any area. Find a local realtor first. Tell him/her your price range, area, number of bedrooms and baths, etc. The realtor can set you up on an "AutoHotSheet" from the local MLS (sets your parameters and searches, each day, for houses that have come onto the MLS). When you find something you like, ask your realtor to contact the listing agent and see if the owners are agreeable to do a lease/purchase contract. There will be a contract to purchase with an end date (1 or 2 yrs out) and a regular lease agreement that spells out monthly payments, deposit, owners & sellers responsibilities etc. You will need to give a regular earnest money check, (held by one of the real estate brokers in a non interest barring acount) to show your intent.
It is a bit complicated, so you should have a Real Estate attorney check out all paperwork so your rights are covered and the sellers concerns are covered, (costs @ $100. in Cincinnati OH area). I have written a couple of these and in the right circumstances with willing buyers and sellers, everyone is happy. Good luck!
