About This Home

As of April 2025

What an incredible retreat in this stunningly upgraded 3-beds, 2-bath fishing cottage on the iconic Conch Key, Florida. Every aspect of this home has been thoughtfully enhanced for both comfort and style. Impact windows and doors, a metal roof, while the interior shines with quartz countertops, bamboo hardwood floors, and exquisite cedar and Dade County pine accents throughout. The home’s layout offers more than meets the eye, with an additional 896 square feet upstairs, providing ample space to accommodate your needs. Enjoy 50 feet of dockage on a pristine canal, perfect for large, deep-draft boats with quick access to both the Gulf and the ocean. Ideally located just north of Marathon and Duck Key. With weekly rentals allowed, this is perfect as an income-producing investment as well.
