506 Horsethief Trl unit: D D Exceptional Development Opportunity - Nearly 6 Acres in Manchaca Located at the southern edge of the City of Austin limits, this just-under-six-acre tract in unincorporated Manchaca presents a rare opportunity for investors, developers, or owner-users seeking flexibility and long-term upside. The property is fully unrestricted, offering maximum freedom for a wide range of potential uses without the constraints of zoning or city ordinances. Positioned just north of the planned SH 45 extension, the site stands to benefit significantly from future infrastructure improvements, including the anticipated connection of MoPac to SH 45, which will provide enhanced regional access and improved connectivity to Central and North Austin. This evolving transportation corridor is expected to accelerate growth and accessibility in the surrounding area. The property sits immediately beyond current Austin city limits, in a path of projected southward expansion as the city continues to grow. As development momentum pushes outward, this location offers strong potential for future annexation and value appreciation while currently retaining the advantages of unincorporated land. Current comps on surrounding land support $250, 000 an acre. With its size, strategic location, and unrestricted status, this property is well-positioned for a variety of uses and represents a compelling opportunity in one of Austin's most dynamic growth corridors.
