BACK ON THE MARKET- Sale didn't move forward for reasons unrelated to the property. Looking for a project with big potential? Set on over 5 private acres in South Thomaston, this property offers water views, room to grow, and two structures ready for your vision—all just minutes from Rockland Harbor, the iconic Breakwater, downtown Thomaston, and the charming fishing village of Tenants Harbor. The main home is a partially renovated contemporary with views of the tidal Saint George River and a 50' deeded right of way to the water. Inside, the bones are solid and the updates have begun—but it's ready for someone to take it across the finish line. The upstairs bathrooms are prepped and waiting for tile, and the kitchen is a blank slate. Finish it out to build equity and make it your own. Closer to Route 131 sits a second structure—likely a tear-down—but it comes with a slab foundation, its own well and septic, and plenty of salvageable elements. Use it as a workshop space, guest cottage footprint, or as the foundation for a brand-new build. The expansive 5-acre lot provides privacy, room to roam, or the option to divide and develop if desired. Whether you're a builder, investor, or hands-on DIY enthusiast, this property is packed with opportunity and priced with its potential in mind. Bring your vision—and your toolbox—and unlock everything this Midcoast location has to offer.
