Self-Sufficient. Solid. Seriously Priced to Sell. This one-of-a-kind rural retreat on 6.31 acres offers everything you need for off-grid living, sustainable homesteading, or simply a wonderful home. Whether you're a prepper, a gardener, or just looking to get away from it all—this property delivers. Built with ultra-durable ICF (Insulated Concrete Forms) construction, the home offers superior insulation, exceptional indoor air quality, and resistance to fire, moisture, and pests—far outperforming traditional builds. It’s built to last. Enjoy multiple heat sources, including radiant heater, a newly installed pellet stove, and a propane backup generator. The well has good flow, and includes hand-pump capability. An underground root cellar made of corrugated steel (8' diameter x 14' long) offers essential food storage, and the land has been chemical-free for years—perfect for organic gardening or permaculture practices. Inside, the main level features two bedrooms, including a primary with walkout to the deck. The basement includes one heated bonus room (no window, think office/gym), a hidden exit, a bath, and tons of potential to build a family room or more bedrooms.
