There's a lot to love about this spacious waterfront home on Big Coppitt Key! Set on a large canalfront lot with peekaboo views of the open bay, you'll enjoy deep-water boating access, paddleboarding or kayaking through the nearby mangroves while taking in the beautiful surroundings, & the beach is just down the road. Key West is just a short drive away, offering the perfect balance of easy access to dining, shopping, & entertainment while coming home to a quieter waterfront retreat.
The outdoor space is one of the property's standout features. A wraparound balcony leads to a spacious, shaded back porch overlooking the canal, creating the perfect setting for relaxing or entertaining. Down by the water, you'll find a wide, clear canal, an 80-foot concrete seawall, and ample parking and storage throughout the property.
Inside, the home offers generous living space along with numerous recent upgrades. Major improvements include a newer metal roof, A/C system, water heater, ductwork and insulation, & updated kitchen. The home has been well enjoyed over the years and offers plenty of opportunity for the next owner to update and make it their own.
