Big Lost River Valley living on 13.1 acres of pastoral ground framed by the Lost River Range. Home to Idaho's tallest peaks and bordered by working irrigated farmland. Sheltered inside a windbreak of mature spruce and shade trees, this solid brick ranch has been lovingly maintained by one family for decades: 1,498 sq ft on the main level plus a 1,312 sq ft basement, 4 bedrooms and 2 baths across both levels. The classic birch-cabinet kitchen with solid-surface counters opens to a bright living room with built-ins, and the glass sunroom off the living area is the showstopper - morning beverage, mountain light, and the hot-tub deck just outside the door. The grounds work as hard as they charm: attached 2-car garage, 16' 20' workshop, three storage sheds, and a grain bin. Private well, private septic and propane forced-air heat.10 minutes to Mackay, with world-class fishing, hunting, and backcountry access in every direction. Four decreed water rights convey with the sale, including senior Big Lost River priorities dating to 1894 and a groundwater right served by the on-site well; water rights documentation package available. Sold as-is; property held in trust. Buyer to verify all information.
