9 bed, 6 bath, 5,086 sqft on 3.01 acres in Austin. Austin, TX 78750. $2,500,000. Round Rock ISD.
**Rare 3 acre estate in Northwest Austin—inside Austin city limits.** Offering a remarkable combination of land, privacy, multiple residences, and resort-style amenities, 9911 Anderson Mill Road is an opportunity that is increasingly difficult to replicate in Austin. The expansive, relatively level property feels worlds away from a typical city lot, yet its Northwest Austin location provides convenient access to U.S. 183, FM 620 and SH 45, connecting the property to major employment, shopping, dining and entertainment destinations throughout the Austin area.
Set beneath mature trees and surrounded by expansive lawns, the property includes three residential structures totaling approximately 5,086 square feet of conditioned space, with a combined 9 bedrooms and 6.5 baths. The multi-structure configuration creates exceptional flexibility for **multigenerational living, guest accommodations, private offices, studios, extended stays or income-producing use**.
The grounds are a defining feature. A private in-ground pool and spa with rock waterfall, extensive patio and entertaining areas, and a fenced tennis court transform the acreage into a private recreational retreat. Beyond these amenities, substantial open lawn and tree-covered areas reinforce the scale, privacy and versatility of the property.
For buyers thinking beyond today's use, 3.01 relatively level acres with multiple existing structures in Austin, Texas 78750 also present compelling long-term optionality. The property may appeal to an owner-user, investor or buyer considering a strategic land hold, live/work concept, repositioning or future redevelopment. Any alternative or future use is subject to independent verification of zoning, restrictions, utilities, entitlements and City of Austin requirements.
More than a residence, this is 3+ acres of possibility within Austin city limits —a private estate today with the land, location and flexibility to accommodate a wide range of visions for tomorrow.
