Good with caveats

Yes, with one thing to plan around. Wells are shallow here, near 110 feet, which keeps drilling costs down. The ground is mostly flat and drains well, which keeps building simple. The growing season is about 146 frost-free days and winter sun is weak, so plan on a greenhouse and a bigger battery bank or a generator.
