Property Description
Think the Florida Keys can't accommodate a true yacht? Think again. Opportunities like this are exceptionally rare--this Port Largo waterfront home is one of the few properties in the Keys where a serious yacht owner can dock with confidence. Set on an over 200-foot-wide canal with protected, deep-water dockage, the property offers a brand-new 106' concrete dock with the depth and turning radius that most Keys homes simply cannot provide. Add in open ocean views and immediate access to world-class fishing and diving, and you have a location that checks boxes most buyers assume don't exist here. Designed for both lifestyle and entertaining, this 4-bedroom, 3-bath home delivers the ultimate Keys experience. The updated kitchen opens into comfortable living spaces, while the outdoor area is built for hosting--complete with a pool and expansive dockage that naturally becomes the focal point of every gathering. This is a true ''boat and entertain'' property. Tucked at the end of a quiet street, the home offers privacy while still capturing the energy of the waterway--perfect for enjoying the steady flow of boats passing through the channel. It's a setting that blends relaxation with just the right amount of activity. Located in the desirable Port Largo community, you're just minutes from some of the best fishing and diving in Key Largo, along with easy access to nearby restaurants and local favorites. The neighborhood also features a park with pickleball and tennis courts, an Olympic-sized pool, beach volleyball, and a convenient boat ramp. For buyers who thought the Keys couldn't support their boating lifestyle, this property changes that conversation. If you've been overlooking the Keys because of dockage limitations, this is the one that proves otherwise.
