The most coveted water in Naples runs behind this lot. In Aqualane Shores, value has always been measured in three things: land, water, and street. This site holds all three. Nearly a third of an acre, 14,810 square feet, on 21st Avenue South, the street Aqualane buyers name first and leave last. At the back of the lot, deep water: one of the canals that made this neighborhood the boating address of Naples, with Naples Bay, Gordon Pass, and the Gulf minutes beyond. The 1978 residence standing here has served its era. What you are buying is what comes next: the site for the home you have been planning in the back of your mind, at the address that justifies building it at full scale. Walk the lot lines. Pace the setbacks. Picture the second story and the water it frames. This is a purchase measured in decades, not finishes. Aqualane Shores was platted once and built out long ago. No one is making more of it, and no one is making more of 21st Avenue South. Opportunities here open when an owner lets go, and they close the same way: quietly, to the buyer who saw the future first.
