TBD Lot 4 Brushy Branch Rd is located in Lockhart, Texas, in Caldwell County. Caldwell County lies at the southern edge of the Hill Country transition, centered on Lockhart, the Barbecue Capital of Texas, home to legendary pitmasters whose craft has drawn food pilgrims from around the world. The county blends working-class Texas tradition with proximity to the booming Austin corridor.

The San Marcos River forms part of the county's northern boundary, and the Plum Creek watershed drains much of the county's rolling blackland prairie and post oak savanna. The terrain is gentler than the Hill Country proper, with broad agricultural plains transitioning to wooded creek bottoms.

Lockhart had an estimated population of 14,708 as of 2023. The 78644 zip code has a median household income of $72,155, a median home value of $242,900, and a median age of 38.6. The average household size is 2.67 people.

Agriculture, barbecue tourism, manufacturing, and Austin metro spillover define Caldwell County's economy. Lockhart has seen significant investment as buyers priced out of Austin seek affordable acreage and small-town living within 40 miles of downtown.
