Good with caveats
Yes, with two things to plan around. Rain is plentiful, about 46 inches a year. The ground is steep, with slopes averaging about 19%. That raises the cost of a driveway, septic, and foundation. Solar is weaker here, about 4.3 hours of full sun a day, so plan a bigger battery bank or a generator.
