An irreplaceable investment opportunity on the crystal-clear waters of Martha Lake. This sprawling, highly unique property boasts nearly 19 pristine acres and approximately 1,000 feet of coveted, western-facing lake frontage. The beautifully wooded acreage features a perfectly level topography with a gentle, moderate slope ideal for a walk-out basement design. Steeped in history as a former vintage resort, the expansive parcel offers unparalleled privacy close to town and immediate potential to either create a grand, private estate or subdivide for a lucrative return. The property includes a 3-bedroom main home with a full basement, an oversized 2-car garage with a private upper-level deck, and three historic 1920s log cabins—including one sitting directly at the water's edge—awaiting your vision. Properties on this pristine, "gin-clear" lake are exceptionally rare; the true value is in this massive, versatile footprint.
