Situated on two 5-acre parcels totaling 10 acres in Costilla County, this mostly fenced property offers an exceptional opportunity for self-sufficient living or agricultural enterprise, with all buildings and infrastructure fully permitted. The impressive 40’ x 50’ steel-and-wood shop sits on a concrete slab and is equipped with power, propane, water supply, and a plumbed drain, along with commercial ventilation featuring two 3’ x 3’ louvered exhaust fans, two commercial-grade dimmable reversible livestock ceiling fans, an 80,000 BTU vented forced-air propane heater, and 3” closed-cell spray foam insulation on most walls. A fully insulated 22’ x 10’ auxiliary building on a slab includes a 10’ x 10’ battery room and a 10’ x 12’ storage area. The advanced off-grid energy system features a 2,000-watt Track Rack with sixteen 125-watt Kyocera solar panels that automatically track north, south, east, and west, a 48-volt system with sixteen Surette L-16 batteries, a 100-amp MidNite Solar charge controller, a 2500-watt continuous OutBack inverter, and a 2,000-watt Freedom 5-blade wind turbine mounted on a 33-foot tower with its own wind charge controller and VRD protection. A substantial 32’ x 72’ reinforced footer with a 4-foot stem wall is already poured, with utilities including power, propane, water, and septic stubbed into the foundation and ready for connection, complemented by a private well with a 120-gallon pressure tank and Grundfos pump and an installed septic system, allowing for the addition of slabs and block or ICF to create a 2,000-square-foot basement beneath a future modular or stick-built home. Completing the property is a 30’ x 160’ FarmTek GrowSpan Premium High Tunnel greenhouse, engineered for durability with ground poles set 3 feet deep in 10-inch-wide 3,500 PSI reinforced concrete, a 72-foot block-filled reinforced footer, an overbuilt west end wall, under-rafter supports on every other hoop, dual rows of purlins the full length of the structure, and a steel frame with reinforced end walls, plus one 1,500-gallon LP tank and one 1,000-gallon in-ground LP tank already connected, creating a rare opportunity to own a fully developed, infrastructure-rich homestead ready for your vision.
