Maine:
When I set up housekeeping here 25+ years ago it has a low cost of living. My 2 BR apartment in a "remuddled" mansion was $400 a month including heat!
Within the last few years though it got "discovered" and rent is the same as Boston.

Good thing I own my home though! We have a lot of old people and getting a contractor or doctor is a hassle.
Yeah the cars rust out but once they turn 25 you don't need a title and can run antique plates without an inspection. Speed limits hit 70-75 and the effective one is higher still.
Heating oil costs money but firewood's cheap and cozy to burn. This summer has been humid which sucks but maybe I can blame el nino. There really are four seasons.
There's an ocean not far to my east but it's clogged with tourists. September-October are awesome.
Driving anywhere else in the country means a day getting out of the northeast and all its traffic on the same route. Then another getting through PA.
Lots of little taxes but no ball busting huge ones. My real estate is $2600 a year, subsidized by "lake people."
