Florida is full of beautiful neighborhoods, but one of them easily rises to the top. According to an analysis by American Home Shield, Port Royal is the most expensive neighborhood in all of Florida by square foot. The home warranty company used a vast database to compare more than 20,000 neighborhoods across the nation, then rank them from least to most expensive in terms of buying property. Nationally, the average cost per square foot is $244, but it’s a whopping $3,375 per square foot in Port Royal. That puts Port Royal in fourth place nationally when comparing what the company calls “America’s Most Expensive Neighborhoods per Square Foot”, and in first place for just the State of Florida, alone. The Collier County neighborhood is easily one of the most sought-after places to call home in Naples.  The majority of homes in Port Royal offer direct water access, as they sit alongside canals or have a beachfront address. The single-family homes of Port Royal are often custom builds and are quite luxurious. It’s common for them to have at least 5,000 square feet of living space, but some are even larger. While some of the homes are priced above $10 million, other homes are priced substantially higher than that.  Several of the homes are privately gated, and the mature landscaping makes them extremely private. The exclusive Port Royal Club sits nearby, with its own beachside swimming pool, exercise facilities, spa services, and tennis. There’s also a residents-only beach. It’s probably not surprising that nearby Aqualane Shores come in right behind Port Royal in fifth place. Behind them, four other neighborhoods in Florida took spots in the top 15. On the flip side, a neighborhood in the Florida panhandle came in well below the national average and ranked among the least expensive per square foot.
