I almost bought a 30 acre lot up in Montgomery, VT. That's near Jay Peak. Received many good reports from @powderfreak and others about the snow potential there. May be some good land deals there to be had still. There were several options back when I looked.
If you plan to build new, be prepared to be very patient. Everything is slower up here and the locals don't move faster if you get all uptight and yell at them.
Given the current situation with shortages and labor issues, it might be even worse. I would strongly consider buying an existing place if you can find something that works for you. Or build but be prepared to wait and deal with delays. It all depends on your personal desires and timeline.
Exciting stuff, please keep us posted as you make your decisions down the road.
