Definitely don’t move to a rural area, even in NH (obviously).

I live in New Boston which is only 17 miles from Manchester, 21 miles from Nashua and 26 miles from Concord. It’s almost impossible to live here without a car. Even then, the nearest gas station is 20 mins away and the nearest grocery store is 25 mins away.

If something looks truly affordable in this area, research it first because not all towns have accessibility and transportation amenities (at all).
