West Virginia is definitely one of the few places in the US that you can still find property cheap. In remote areas if you are paying more than a $1000/ac, you are paying too much. I personally bought a 400 acre tract last year that went for around $225/ac (mineral rights included) and I currently know a tract in Wayne county (Kermit area) (430ac) for sale that the owners want about $500/ac.

To find land in the Greenbrier area, get a subscription to the local newpapers. This is an easy way to watch for land for sale. Also watcing the ad bulletin is a good idea. I would also check with several realtors in the area. You can tell them what you are looking for. If they don't currently have anything, you can always have them call you if anything becomes available. Good Luck!
