Just south of Nashville in Franklin and south Williamson county it is still fairly common to find nice homes on 5 to 20 acres of land. I've noticed that during this supposedly slow real estate market that these homes are still very much in demand. I think most people realize that the land will become harder to come by in the future.
If you are interested in acquiring a home with land, south and west Williamson county is still probably the best place to invest your money. That is, if you don't mind having neighbors like the Judds, Tanya Tucker, Kix Brooks, Keith Urban, Kenny Chesney, George Jones, and all their friends.
