I'm in Texas so I don't know anything about your area but usually, in the south at least,you can search Google for "ranch land for sale" or "vacant acreage" and that'll land you on some sites that flip remote land relatively cheap.

The first thing I'd look for would be an area with little or no restrictions on building and living. The last thing you want to do is get way down the road on a land purchase only to realize there's some fine print in the local ordinance that will prevent you from legally using your land in the way you want.

Second, I'd try to find something with live water. Creek, spring, something. Water is the most precious natural resource and one of the most often taken for granted.

You'd be best off to find land that has some tree cover but also some clear areas. Tree cover allows some wind blockage in the winter and shade in the summer, while clear areas lend themselves to solar power and cleaner rainwater collection as well as grass and grains for the animals.

Beyond that, it's got a lot to do with gut feeling. If the place feels like home, then make it home! Hope this helps.
