I HIGHLY recommend North Georgia around Dawsonville. I have a dear friend who owns a farm there (600 acres or so) and the area is really nice. Cooler and wetter than Atlanta, and really nice roads.

Here's one acre properties:

I set this to start at $150,000 but there are more reasonably priced homes in the same area. Just change the pricing on the top bar. I set it for one acre properties plus, so you won't see any half acres.

Have fun browsing!
This one is near my friend's place on Cowart and Kelly Bridge Roads:
