About the Area
TBD Mountainside Dr is located in Lago Vista, Texas, in Travis County. Travis County is home to Austin, the capital of Texas and one of the fastest-growing major cities in the United States. Beyond the urban core, Travis County still contains significant ranch and acreage properties in its western reaches, where the Hill Country meets the city and land values reflect both agricultural heritage and proximity to one of America's most dynamic economies.
The Colorado River flows through Travis County, impounded into Lake Travis and Lake Austin, key recreation anchors for the region. The Balcones Escarpment marks the transition from the limestone Hill Country in the west to the Blackland Prairie in the east. Barton Creek and its tributaries carve spring-fed swimming holes and nature preserves within the urban fabric.
Lago Vista had an estimated population of 9,341 as of 2023. The 78645 zip code has a median household income of $108,393, a median home value of $387,200, and a median age of 51.6. The average household size is 2.3 people.
Austin's economy is anchored by the University of Texas, state government, and a massive technology sector that has attracted Apple, Tesla, Oracle, Dell, and hundreds of startups. Travis County acreage properties command premium prices reflecting proximity to the Austin job market, major airports, and world-class amenities.
