This is one of those opportunities that rarely comes to market, and when it does, it’s recognized for what it is: a true legacy property. Set on approximately 2.19 acres along the main body of Lake LBJ, this property offers an extraordinary 311 feet of waterfront—an increasingly rare combination of scale, privacy, & presence on one of the most sought-after stretches of the lake. The setting is both peaceful & expansive, w/wide open water views framed by a canopy of mature trees that provide natural beauty, shade, & a sense of seclusion that is difficult to replicate. The existing home on the property is livable & could be enjoyed as-is or updated over time. However, the true value here lies in the land itself—its size, frontage, & the flexibility it offers for the future. Whether that vision is to create a private waterfront estate, design a multi-generational family compound, or explore the potential to subdivide into multiple homesites (buyer to verify), the possibilities here are compelling. The property was originally platted as three lots, adding an additional layer of flexibility for those considering long-term use or investment. One of the property’s most unique features is its own small island just off the shoreline-an uncommon detail that gives the setting a true sense of character & place, creating an experience that feels distinctly your own. Life on this stretch of LBJ centers around the water, from quiet mornings under the trees & glassy conditions for skiing or paddling, to afternoons spent boating & gathering with family/friends. Evenings bring sweeping Hill Country sunsets across the main body of the lake. With constant water levels & unobstructed views, the property offers both beauty & usability, all within easy reach of every day conveniences. Properties with this combination of acreage, main body location & 300+ feet of frontage are exceptionally limited! This is an opportunity to secure a piece of Lake LBJ that can be enjoyed for generations.
