Significant challenges
Possible, but winter will be hard. The growing season is about 131 frost-free days and winter sun is weak, so plan on a greenhouse and a bigger battery bank or a generator. Wells are shallow here, near 100 feet, which keeps drilling costs down. Septic will likely cost more, because the soil stays wet for long stretches.

Rain
Rain helps, but plan on a well for most of your water and on watering the garden in dry months.

The typical well here is about 100 feet deep; a well typically runs $7,000 to $15,000
Growing season
Short. Start seeds indoors and favor cold-hardy crops.
About 131 frost-free days, USDA zone 3b; last frost about May 15, first about September 25
