About This Home

Offering 461.24 +/- acres in Bexar County bordering Calaveras Lake, this expansive property presents a rare opportunity to acquire substantial acreage near San Antonio's southeastern growth corridor. Comprising of four separate parcels, the offering provides flexibility for phased development, individual tract sales, land banking, agricultural operations, or a larger coordinated development concept. Depending on the parcel, the property offers road frontage on as many as three sides, creating multiple potential access points and giving developers greater flexibility when evaluating circulation, entrances, utility placement, and future tract configuration. The property is located less than two miles from the San Antonio city limits, US Highway 181, and Interstate 37, providing convenient connectivity to San Antonio, surrounding employment centers, and major transportation routes. Its proximity to established residential development, industrial activity, and regional infrastructure strengthens its long-term investment appeal. Power is available and already onsite on certain parcels, and the property lies within the designated coverage area of a water service provider. Buyers should independently verify utility capacity, availability, zoning, floodplain conditions, development requirements, and intended land use. The land itself offers a diverse mix of open pasture, scattered mature oak trees, dense native brush, open pockets, ponds, and lake-bordering acreage. Two residences are located on the larger parcel, including a historic home, along with a metal barn and existing agricultural improvements. The property is well suited for cattle and supports abundant native wildlife, allowing continued agricultural or recreational use while future plans are evaluated. With its scale, multiple parcels, extensive road frontage, proximity to San Antonio, utility availability, and boundary along Calaveras Lake, this property offers a compelling canvas for developers, builders, investors, ranch operators, or buyers seeking a strategic long-term landholding. Potential concepts could include residential, commercial, recreational, conservation-oriented, or mixed-use development, subject to all applicable governmental approvals and feasibility studies. The unusual combination of accessibility, acreage, water adjacency, and development flexibility makes this one of the more distinctive large-tract investment opportunities in the San Antonio area.
