I live in Choctaw and it is a City that has a lot of For Sale By Owner properties. Can you provide more information on what you are looking for? I know of one in particular that has a very nice home on it. If you are just looking for acreage I know of a few that might be willing to subdivide. Would have to check.
Are you working exclusively with a Realtor? If not, contact me with your information and I would be happy to send you any properties that come up automatically from the MLS that match what you are looking for.
What is your price range? I did a search and there were none between 15 and 20 but I found one with just over 24 for $168,770 on SE 29th, unless you want something with a home built on it, in which case there are two starting at $595,000
