I say Maine, if you are not concerned with ever trying to find employment.
The positives:
The land is beautiful, the ocean is close, we are 85% wooded.
For under $400k you can live wherever you want, even right on the ocean!
I have 12 acres, am an hour from the coast, 15 minutes form the 2nd largest "city" and 30minutes from the biggest. We have 12 acres of field and woods, a 3 bedroom home, a 2 story 2 car garage and a another 3 car garage that has been modified into a barn. My back property is bordered by a river and it is beautiful! All for around 100k
Traveling is always by car, though we are getting Amtrak in limited areas and do have bus and taxi service in some of the larger cities. Crime is low! Fall is beautiful. Summers mild, we rarely reach 100 degrees F. Spring is unpredictable and Winter can be both harsh and wonderful.
The negatives:
Culture is non-existent. A lot of cookie cutter restaurants and big retailer's, unless you are on the coast near route 1, somehow they are managing to keep the Wal-marts out!.
Work is hard to find, but we are growing.
You pretty much have to drive everywhere unless you live right in downtown Portland or Lewiston.
Snow is inevitable, so if you don't like snow, well not the state for you.
