Discover the perfect canvas for your custom dream home at 21100 Santa Carlo Avenue in Lago Vista! This gently sloping 0.36-acre lot is nestled just 1,260 feet from the sparkling waters of Lake Travis (when at full pool) and a quick 5-minute golf cart ride (2 miles) from the Lago Vista Golf Course clubhouse. Imagine enjoying panoramic lake views and breathtaking sunsets from a thoughtfully designed, modern build-especially if you include a rooftop deck. While most of the lot sits in the 500-year floodplain, and approximately 30% in the 100-year floodplain toward the back, this unique location offers a tranquil hillside setting and a rare blend of close water access and scenic vistas. Take advantage of the convenience and lifestyle that Lago Vista is famous for: boating, fishing, golf, and an ever-growing community. Seize this opportunity to build in a coveted area that combines natural beauty with modern amenities. Don't wait-contact us today and start envisioning your future home by the lake!
