21 THUNDER VALLEY RD This 19.58-acre Hill Country property offers a rare combination five minutes from downtown Boerne in Kendall County. With multiple wells and septics, water infrastructure throughout, new fencing, and a seasonal stretch of Menger Creek along the entire back boundary, the land is set up for immediate use. A newly built 1, 100-square-foot modern casita with a fully climate-controlled garage anchors the property, providing comfortable living quarters while you design and build your main estate. Multiple accessory buildings, a cattle pen, and a working shoot support livestock operations under the current ag exemption. The property balances working ranch utility with hunting recreation and custom home development, all within minutes of Boerne's historic downtown. The tract sits on the rolling limestone terrain typical of the Edwards Plateau, with live oaks, native grasses, and a spring-fed creek system that attracts whitetail deer, axis deer, turkey, and dove. Water infrastructure is already in place, new perimeter fencing secures the boundaries, and the accessory buildings give you flexible space for equipment, livestock, or storage. The climate-controlled garage protects vehicles and tools year-round, and the modern casita offers immediate occupancy or guest quarters while you plan your main residence.
