Here is my thread from 2020.
Some good perspectives in here.
@ORH_wxman can tell you if you are buying in a snow hole. He saved me from buying a dud.
NNE microclimates are such that a couple miles can make a huge difference in snow totals.
You will also need to think about what is more important: a lot of smaller, more reliable snows, bigger synoptic events that can dry up and miss for a long stretch, or to be a mega-retention queen where you hold on to every flake that does fall.
Each area has strengths and weaknesses in these aspects.
We like our area given we do OK in all of these aspects and we have civilization nearby in the form of several towns and Berlin which is a little redneck but still has schools, a decent hospital, etc.
In NH, I would not go any further north than Milan. Beyond that, it gets really desolate and frankly kinda depressing as a living situation, especially in winter. I'm sure there are great land deals up there, but it's bleak.
Stay out of Whitefield. Decent little town but has a snow hole that shows up in nearly every event.
A lot of SNE people seem to like the Conway zone but I find it to be way too crowded and touristy and they suck at snow (comparatively to here), IMO. It's always 5-7 degrees warmer there than here. I would stay away if you are looking for a quieter mountain retreat. Kinda reminds me of a tourist beach town transplanted into a somewhat mountainous area.
The VT and Maine crew will know more about their areas.
