Where to Look

First off, I wanted to thank whoever compiled the links in the moving to Roanoke section. Lots of great information there.

My wife and I want to move to the mountains to get away from the humidity of central NC. We were originally planning to move to the Asheville area but it's so expensive there. I came across Roanoke as being a great place to live so I'm coming up to visit for a couple of days in a little over a week. From what I've read, it still gets humid in Roanoke so I have been looking into the Roanoke area mountains. I work remotely so I would need cable internet but would prefer fiber optic internet. We would like to be no more than 20-30 minutes from Roanoke because my wife would probably look for a job there. We would also like at least an acre with lots of trees and are open to buying a house or land to build on. Ideally, we would not want to spend more than 400k.

Does anyone have any suggestions on where to look or where not to look during my visit? Thanks in advance for any information you could provide.
