Two fully usable pastures make this an ideal setup for hobby farmers or homesteaders, including an upper pasture with woven wire fencing and a lower pasture previously used for horses, plus an additional dry lot for flexible animal management. The 40x30 outbuilding is thoughtfully equipped with four 10x10 stalls, a built-in 10x20 chicken coop with outdoor run access, feed storage area with interior water hydrant, and electricity already installed. The grounds have been lovingly curated into a pollinator's paradise with over 100 varieties of perennials and native plants, meandering garden paths, mature blackberry bushes, garden space, and cleared space for a future greenhouse near the barn. Rare opportunity for country living with everyday conveniences.
