I actually want to do everything you're outlining as well, but here in the northeast they're trying to sell ~1 acre for > $100,000 in a lot of desirable "rural" towns. Definitely makes it harder to get into unless you want to commit to far far north.
I've been watching a lot of TV shows that have revealed a lot of pros/cons about different areas of the country. The further north means a much shorter growing season which makes a greenhouse even more important. It also means a lot more infrastructure is required to keep any livestock alive during the longer winters. Places like Texas goes the other direction where the heat during the long summers is brutal, but it means early spring and late fall crops. I really wouldn't want to be any further north than 40°.
Got to find that perfect plot of land that has water, some trees for wood, some land that can be farmed and hopefully a clear sky to the south for solar. Oh, and it's gonna need to be far enough from a city so my telescope can finally be used the way it was meant.
Maybe the Shenandoah would work.
