Go with a town that has a government. There are plenty of them that are still cheap and have the advantages you list. And it all depends what you intend to grow and what post-harvest value added processing you want to do. And the unorganized territories tend to be woods rather than much usable farmland. Clearing land isn't easy.
I'm in 04617. I have a house I don't care to heat, so I've gone with alternative housing. I have plastic carboys of water I fill from the house, and I may have to drain more plumbing if the winter gets cold. I have fair internet, which reaches to my new digs. I heat water on a stove and it drains out to a big leaf pile. There's a
compost pile in the woods where I dump my cat's box and my toilet, which use similar wood fiber technologies. Next summer I'll be renting out the house to the rusticators for as much as the market will bare.
I have this nice broom. I bought it from southern Oregon neo-hippies at a craft fair in 1998. They'd grown the broom corn, harvested an almost straight ash pole for the handle, and made the broom. That was their cash crop. It didn't matter that their home was 300-some miles south of where I bought it. Value added.
