There are several lease-to-own options in Norman. I have a builder and an investor who have this option available for their home(s). Please visit the website below & provide the following information in "contact me" link: Price range needed, available down payment, lease-to-own terms needed, maximum age of home, minimum square footage, & minimum beds & baths.
Also, DMG Real Estate, Rent King, and Sterling Properties are just a few of the other companies in Norman, with this potential option. You may contact them by googling their company name and location.
Some Realtors have this as an option in their "Selling Terms". A Realtor, like me, can provide a search basis with this option & the other options mentioned above.
