About This Home
Lake Austin's most spectacular waterfront home under $9 Million.
* Recently completed $2 Million remodel
* Single stall 2 story refurbished boat dock
* 4 bedrooms / 4.5 bathrooms
* Huge rear glass balcony with beautiful lake views
Lake Austin is Austin's most exclusive waterfront corridor - 22 miles of constant-level shoreline in 78732, 15 minutes from downtown. Waterfront homes start around $4M and trophy lots with 200+ feet of flat shoreline trade at $15M-$35M+. The lake is controlled by Tom Miller Dam, which maintains consistent water levels year-round - the key advantage over seasonal Lake Travis.
This is one of Austin's thinnest markets. Roughly 22 miles of total shoreline, and at any given time only 3-5 homes are actively listed. Many of the best lots trade privately through agent relationships before they ever reach the MLS. The finite supply creates a structural price floor that insulates Lake Austin from broader market cycles.
Buyers here want water access as daily life, not a weekend plan. Morning paddleboard, afternoon ski run, burgers at Ski Shores by boat, sunset from your own dock watching Hill Country ridgelines. The practical side matters too: you are inside Austin city limits with full services, 15 minutes from downtown, 10 from the Domain.
Four Seasons Private Residences is under development on 145 acres with 188 planned homes - the first significant new inventory since the lake was established. Eanes ISD and Leander ISD serve different sections of the corridor, both with strong school ratings.
