Just four homes from open water, this elevated Keys retreat offers instant Gulf access and an exceptional waterfront setting. Enjoy 100 ft. of private water frontage with no neighbors across the canal (undevelopable, buyer to verify), a 70 ft. composite dock and a tiki hut at the water's edge—with a boat basin at the end of the canal allowing easy turn-around for boats up to 40 ft. (current owner has navigated it comfortably). The resort-style backyard features a heated/chilled concrete pool, elevated hot tub deck, firepit, lush landscaping and shaded patio spaces. Inside, soaring vaulted ceilings, an open layout and nearly wraparound porches create seamless indoor-outdoor living. Built to last with Hardie board siding, impact windows and a pull-through paver driveway with covered parking and garage—all tucked away on a quiet street, yet close to everything Marathon has to offer!
