This Lake Travis waterfront homesite at 21909 Mockingbird Lane offers a rare chance to create a custom retreat in the heart of the Texas Hill Country. With a gentle slope toward the water, mature trees for privacy, and utilities available at the street, the property provides an ideal canvas for a home designed to capture lake views, natural light, and seamless indoor-outdoor living. From quiet mornings overlooking the water to evenings defined by expansive Hill Country sunsets, the setting supports a lifestyle centered on both relaxation and connection to nature. Located in the Lago Vista community, ownership includes access to private waterfront parks, boat launches, a fishing well, pool, fitness center, pickleball courts, and golf course through the Lago Vista POA. Lake Travis offers endless opportunities for boating and recreation, while downtown Austin remains within an easy drive. An added opportunity exists with the adjacent submerged 4-acre tract owned by the City of Lago Vista, which may potentially be available to expand water access or enhance privacy.
