Outdoor recreation is close at hand with Lake McQueeney, the Guadalupe River, and Starcke Park Golf Course all within a short drive. This combined 36 acre tract features a desirable mix of open pasture and wooded terrain, creating a versatile landscape ideal for homesteading, recreation, or light ranching. Mature oak trees provide shade and natural privacy, while open areas offer multiple build sites with flexibility for future improvements. Internal road construction will be completed prior to purchase, and paved road frontage ensures easy access. Electricity is available at the property line, and guidance on water well installation, fencing, and additional improvements is available, allowing for a smooth path from purchase to development. Native wildlife including whitetail deer, turkey, hogs, and dove are abundant, supported by the balance of open fields and wooded cover. A wet-weather creek traverses portions of the property, adding natural character and seasonal water flow. Surrounding wells tap the Carrizo Aquifer at depths of approximately 300–400 feet, often producing 30–80 GPM, providing strong potential for reliable water. The property benefits from an existing agricultural valuation, helping maintain low property taxes.
