Neighborhood Context

About Westlake Hills

Westlake Hills is Austin's most prestigious address. The small city of Westlake Hills sits in the hills west of Austin proper - with views of the city skyline, the Texas Hill Country, and Lake Austin visible from many properties. It is where Austin's most successful executives, entrepreneurs, and professionals choose to live.

The primary driver of Westlake's demand is Eanes ISD - consistently ranked among the top school districts in Texas and regularly appearing on national top-100 lists. Families move to Westlake specifically for Westlake High School, and the school's reputation sustains property values through every market cycle.

🎓
Eanes ISD

Westlake High School is among the top public high schools in Texas. AP course offerings, athletics, and college matriculation rates rival private schools. This is the #1 driver of Westlake real estate demand.

🏔️
Hill Country Views

Elevated terrain means many homes have panoramic views of downtown Austin's skyline, Lake Austin, and the surrounding hill country. Views add significant value and are irreplaceable.

🔒
Privacy & Security

Many Westlake properties are set back from the road on large lots, often in gated communities. The density is far lower than inside Austin proper.

⏱️
Downtown Access

Despite feeling removed, Westlake is 10 to 15 minutes from downtown Austin via MoPac. The hills buffer from city noise without sacrificing access.
