About This Property

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.

	No attention to detail was spared in this very spacious 3 bedroom 2 bath Fishing Cottage on historic Conch Key. Major upgrades include impact windows and doors, metal roof, Hardie board siding, Trex decking, quartz counters, bamboo hard wood floors, and cedar and Dade county pine walls and ceilings. Has an additional 896 square feet upstairs that is not currently counted in the square footage, so the home is much larger than it seems. Approximately 50' of dockage on a crystal clear canal with easy gulf and ocean access. Can accommodate large boats with deep draft. Plenty of parking on the left side of home for multiple vehicles. Located North of Marathon and Duck Key, so it is an easier drive back up to the mainland. Weekly rentals are allowed. Can be sold turn key and furnished as well.
