Also I hear that "land is cheap elsewhere" argument all the time. You're right; if I was 82 and wanted to settle down I'd buy a ranch somewhere in the palm desert for 100k, but I'm not. I'm young and I want to work. I'll live in my shitty apartment in SF long before I whither away on some plot of land in the midwest any day.
Yes there are cheap houses in swamplands; probably a dollar an acre. But then what? Cool I have cheap house totally removed from all the action.
However, if that's your thing then do it.
