About This Home

As of August 2025

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. Additional features include: New windows, new gorgeous steel log siding, new pellet stove, new exterior stonework, fresh interior paint & some updated radiant heaters, a 16x20 greenhouse (repairs rqd) and a 12x20 steel carport. This property is being sold as is and borders 400+ acres of USFS land!
