of 100
Good with caveats
Yes, with one thing to plan around. Water is easy here, with about 50 inches of rain a year and wells near 60 feet. The ground is steep, with slopes averaging about 41%. That raises the cost of a driveway, septic, and foundation.
What the land says
Rain
Rain can supply much of a household's water with a large tank. A garden mostly waters itself in normal years.
About 50 inches a year (PRISM, 1991 to 2020 average)
Wells
Shallow wells, so drilling should be one of the cheaper costs.
The typical well here is about 60 feet deep; a well typically runs $3,000 to $8,000
Growing season
A full season for most vegetables.
About 182 frost-free days, USDA zone 6b; last frost about April 21, first about October 21
Sun
Good sun. Size the array and battery bank for winter.
About 4.6 hours of full sun a day, averaged over the year

Terrain
