Since you probably don’t have the means to get there unless you have access to an interstellar spaceship, teleportation device, or stargate, you might have to settle for earth.
Oregon is pretty good on the east side of the cascades as far as cheap land and low cost of living…much prettier on west side, but more expensive.
As mentioned Oklahoma, Arkansas, and with that Missouri, Tennessee and West Virginia are all pretty low cost of living…the more rural the better, but as far as jobs there would be less…there are still opportunities though.
I can think of some more really nice places but with higher cost of living like western Canada, Alaska, Washington state. Maine is actually a pretty good state in the north east.
Parts of Siberia, but you would need some connections and unfortunately due to present political nonsense it wouldn’t be a good idea…
