Introducing this charming and newly upgraded Keys Conch Cottage tucked away in the desirable Tropicana subdivision in the heart of Marathon. Set on an impressive 8,000+ sq ft lot, this property offers the rare benefit of flexible mixed-use zoning, allowing for short-term vacation rentals, home-based businesses, and even the potential to divide the side portion of the lot for an on-property business space, an exceptional opportunity for versatility and income potential. It is currently an active, licensed vacation rental with repeat guests already in place. Inside, you'll find a cozy 2-bedroom, 1-bath layout complemented by a large, oversized workshop ideal for storage. The home has been thoughtfully updated with 3 brand-new mini-split air conditioning systems, providing excellent cooling and energy efficiency. All appliances have been upgraded within the last year to matching white KitchenAid, giving the kitchen a clean, cohesive, modern look. Additionally, both the exterior and the entire interior of the home were freshly painted within the past year, offering a crisp, move-in-ready feel throughout. Brand-new impact windows and doors add further value with improved energy efficiency, security, and storm protection, while mature tropical landscaping enhances the authentic Old Florida Keys charm. Step into your private backyard retreat, where lush greenery creates a serene, secluded atmosphere. Enjoy a relaxing soak in the hot tub under the stars, entertain friends, or simply unwind in your own island oasis. The expansive lot provides ample parking for multiple vehicles, trailers, and boats—perfect for an active Keys lifestyle. With three public boat ramps just minutes away and close proximity to the world-famous Sombrero Beach, enjoying days on the water or in the sand is effortless. Whether you're seeking a personal island getaway, a strong income-producing investment, or a unique property with zoning flexibility this is the place for you!
