San Marcos TX Waterfront Real Estate, Homes, Condos for Sale

7 Beds ⋅ 4 Baths ⋅ 9472973 MLS ⋅ 78666 Zip Code

Unlike commodity commercial or residential assets, this property is likely to appeal most strongly to a buyer with a specific vision for adaptive reuse or experiential-oriented development. The existing improvements, combined with the site’s natural setting and utility infrastructure, create potential for a wide range of uses subject to buyer due diligence and municipal approvals. The existing structure is older but has undergone recent updates. Historically, the property functioned in a group-house/fraternity-style capacity, and the current layout may lend itself to concepts such as lodging, boutique hospitality, retreats, event-oriented use, group living, wellness-oriented programming, or other adaptive-reuse opportunities. Prospective purchasers should independently verify any intended use with the appropriate governmental authorities, including zoning, floodplain regulations, parking requirements, building code compliance, fire/life-safety standards, and permitting considerations. Utility availability represents another major advantage of the property. For many river-oriented hospitality or experiential uses - including bed & breakfast concepts, event facilities, retreat accommodations, restaurant use, glamping, RV-oriented concepts, or group housing - existing utility infrastructure can significantly reduce development barriers, timelines, and upfront capital requirements.

Walking your own land to a hidden grotto, private waterfall & even unexplored caves—features most will never experience, let alone own. Tucked beneath a dense canopy of mature trees along the Blanco River, this is not just a home—it’s a one-of-one Hill Country compound where natural beauty & privacy converge in a way that cannot be recreated today. Just minutes from IH-35 & within 30 minutes of Downtown Austin, it offers the rare balance of convenience & complete escape.
