Lago Vista, TX 78645 (Travis County)
About this property
Set on 10.317 acres in the Texas Hill Country, this property offers a practical opportunity to build, invest, or hold land in an area where larger tracts are becoming harder to find. Located within Leander ISD and surrounded by a quiet stretch of countryside, the property directly borders a 580-acre section of the Balcones Canyonlands National Wildlife Refuge—part of more than 25,000 acres of protected land—providing long-term privacy and preserved natural surroundings. This tract has been surveyed from a larger 34.851-acre property, giving buyers the option to start with a manageable footprint while maintaining the ability to expand. An alternative purchase option is available for the full 34.851 acres, which includes a 2-bedroom, 3-bath home and existing improvements (MLS #8938820). The land features rolling terrain with a mix of open and wooded areas, offering multiple potential building sites and flexibility for a range of uses. Located within the ETJ of Lago Vista and outside of typical subdivision restrictions, the property supports a variety of residential, recreational, or long-term investment plans. Pedernales Electric service can be extended to the tract, and Jonestown Water Supply has indicated that a water line extension may be possible. Combined with minimal permitting requirements in the area, the path to development is relatively straightforward compared to more restricted locations. Positioned approximately 20 minutes from Cedar Park and under an hour from Austin, the property offers a balance of accessibility and separation. With usable acreage, adjacency to protected land, and long-term flexibility, this is a solid opportunity in western Travis County.
