100’ of stunning deep-water frontage on constant-level Lake LBJ, this one-of-a-kind waterfront retreat is the property buyers dream about and never forget. With its iconic rounded roofline, sandy beach shoreline, peaceful open-water views, and proven short-term rental success, From the moment you arrive, the architecture sets this home apart. The distinctive curved roofline creates a striking presence while the interior was designed for gathering, entertaining, and maximizing lake views. The sandy beach paired with a boat lift and deep water is one of the rarest and most valuable features on Lake LBJ. Adding to the serenity, the land directly across the lake remains undeveloped, creating a peaceful natural backdrop of Packsaddle mountain and wide-open water views that are becoming increasingly difficult to find on LBJ. Despite the quiet setting, you are only a 5-minute boat ride from Boat Town Burger Town, waterfront dining, marinas, and everything people love about Lake LBJ. This property is also an exceptional income-producing STR with strong revenue, outstanding reviews, and loyal repeat guests who return year after year because there is simply nothing else like it. The home already performs at a high level, but future upside remains through elevated marketing, branding, and higher nightly rates. This is a rare opportunity to own one of the most unique waterfront homes on Lake LBJ. Special properties like this rarely come to market — and even more rarely offer this combination of deep water, sandy beach, privacy, architecture, and proven income potential
