Set on a nearly 15,000 square foot lot in Tavernier, this property provides room to spread out, entertain, and enjoy outdoor living -- a true advantage in the Florida Keys. Located near local schools, dining, and everyday conveniences, with a nearby boat ramp providing quick access to fishing, diving, and exploring the surrounding waters, this home offers the lifestyle people move to the Keys for.
