Overview
Description
*Open House: Sat Aug 29 11am - 1pm, Sun Aug 30 1pm - 3pm* Major price improvement—now offered at $2,299,000. Motivated seller and ready to review offers. This modern ranch on 1.5 private acres in Appaloosa Run offers Hill Country privacy just minutes from SH 45 and MoPac—and only 20 minutes from downtown Austin. The main residence features 4 bedrooms, 3.5 bathrooms, a dedicated office, flex space, and a 3-car garage, plus an attached 1-bedroom, 1-bathroom casita with a kitchenette and private entrance—ideal for guests, multigenerational living, or income potential.
Soaring ceilings, a floor-to-ceiling fireplace with a 72-inch insert, and 10-foot sliding glass doors connect the main living area to the covered deck, tiled pool surround, outdoor shower, and entertaining spaces. The kitchen features Italian Calacatta Monet marble, a commercial gas range, double ovens, custom hood, butler’s pantry, and a sink overlooking a lush interior atrium.
The primary suite is a true retreat with a spa-inspired bathroom, oversized shower, boutique hotel-style finishes, and custom closet details. Additional upgrades include solid-core doors, foam insulation, irrigation, gutters, and a private well. Mature trees, native wildlife, and peaceful acreage complete this rare offering.
Zoned to Baldwin Elementary, Gorzycki Middle, and Bowie High. Schedule your private showing today.
