Nebraska is another one of those very reasonable states, where you can get an 'all in package' on staying alive for barely more than fifteen thousand dollars. You might have to get somebody to build you a house so you can move into it though; part of the reason it's so cheap is that there just isn't anybody living in most of it. That's why it goes by the nickname of 'The Great American Desert,' You can do wonderful things with all that space though - just ask the US Military, who base their Strategic Air Command here.
When it comes to farming, Nebraska doesn't just have the rest of America beaten; it puts almost all of the rest of the world to shame. The state is one of the largest exporters of agricultural products anywhere on the planet. Just be prepared to deal with some very extreme weather if you decide to make it your home; the whole state is a near-permanent theater of thunderstorms and tornadoes.
