OVERVIEW

About this lot

Flat, 0.6-acre waterfront lot on Lake Travis with year-round lake views and the potential to build a private boat dock right in your backyard. Situated on a deep, protected cove that opens directly to skiable Lake Travis, this lot gives you calm water in the cove and open water just beyond. Mature oak trees provide natural shade and character, and the flat terrain makes for a straightforward build. Full utilities are available at the street. As a Lago Vista POA member, you get access to a network of private waterfront parks, a marina, boat launch, fishing pier, community pool, and golf course. Short-term rentals are permitted, making this a strong investment opportunity as well. The adjoining lot is also available, offering the chance to combine parcels for a larger build site or added privacy. Located about 20 minutes from Cedar Park and 35 minutes from Austin, this is lakeside Hill Country living without the commute trade-off.
