Neighborhood guide and local insights
Westlake Hills is an incorporated city in Austin's 78746 ZIP code, five minutes west of downtown via Bee Caves Road. Eanes ISD - ranked #1 in Texas by Niche 2026 - draws most buyers. Median home price $2.4M, with estates from $1.2M updates to $10M+ hilltop compounds. Roughly 1,000 total homes sit on wooded lots averaging half an acre to two acres, spread across the hills south of the Colorado River. Lost Creek, Davenport Ranch, The Oaks, and Bee Caves Woods each have a different character - from 1970s ranches on established lots to new-build Hill Country Contemporary estates with 20-foot ceilings and limestone facades. The housing stock is in a generational transition. Original 1970s-80s ranch homes sell as teardowns at $1-2M for land alone, replaced by $3-8M contemporary builds. At any given time, 25-30 homes are actively listed. Inventory is tight, and a meaningful share of deals happen off-market through agent networks. What defines daily life here: morning coffee at Swedish Hill, school drop-off at Eanes Elementary or Bridge Point, a trail run at Wild Basin Preserve, and dinner at Sway or Las Palomas without crossing MoPac. This is a quiet neighborhood built around schools and outdoor access, not nightlife or walkable retail. The people who live here chose it for exactly that trade-off.
