The Allure of Private Islands in Florida
May 2025 | Brittney J. Miller
Private islands have long been the stuff of dreams, often symbolizing status and luxury for America’s wealthy elite. In the United States, few places embody this concept more than Florida, a state teeming with exclusive private island properties. According to Jenna Stauffer, a real estate broker for Sotheby’s International Realty, the island market in Florida is not only active but increasingly vibrant, reflecting a surge in demand driven by an influx of affluent residents.
The Growing Demand
The number of private islands sold in Florida is difficult to quantify, largely due to the prevalence of off-market deals. Recent trends indicate a boom in the luxury real estate sector, spurred by a significant migration of wealthy individuals. A study by fintech firm SmartAsset ranked Florida as the top state for net migration among affluent young Americans in 2024, further intensifying demand for high-end properties.
Stauffer notes, “There’s always demand from high-net-worth and ultra-high-net-worth buyers looking for privacy, luxury, and their own slice of paradise.” The naturally limited supply of islands compounds this demand, with Florida boasting over 4,000 islands of 10 acres or more—the second highest in the country, trailing only Alaska.
Pricing and Features
When considering purchasing a private island in Florida, prices can vary significantly based on size and development. Smaller, undeveloped islands are often priced between $1 million and $5 million. In contrast, islands with existing infrastructure can start at $10 million and extend to $50 million and beyond. An example is Pumpkin Key, a luxurious 26-acre isle featuring a 20-slip marina and a helipad, currently listed at $75 million.
Another key trend in the island market is the rising interest in eco-conscious features. Contemporary buyers increasingly seek properties that incorporate sustainable construction, off-grid solar options, and designs resilient to hurricanes.
Spotlight on Florida’s Unique Islands
Florida is home to a plethora of unique private islands, each offering distinct experiences and purposes. Here are some noteworthy highlights:
Black’s Island
Location: Port St. Joe, Gulf County
Originally rumored to have been owned by the infamous pirate “Black Sam” Bellamy, today, Black’s Island has transformed into a luxury vacation hotspot. Following its acquisition by Atlanta developer Scott Seymour, the island now hosts 26 bungalows, all elevated to withstand hurricanes. Visitors can rent these bungalows starting at $850 per night.
Ever After Estate
Location: Unincorporated Lake County
Andrew Greenstein turned an ordinary property into a whimsical 62-acre vacation retreat. Featuring 13 bedrooms and various playful amenities—such as a waterslide leading into a waterfall-fed pool—Ever After Estate attracts family reunions and business retreats alike, with rentals priced around $3,000 a night.
Beer Can Island
Location: Tampa Bay, Hillsborough County
Once a docking station during World War II, Beer Can Island is now a colorful hub for boaters and partygoers. Russell Loomis, its co-owner, transformed it into a recreational destination with a tiki bar, food truck, and concert stage. Amid challenges, including hurricanes, Loomis is innovatively introducing a cryptocurrency membership model for visitors.
Legacy Island
Location: Fort Myers, Lee County
This nearly acre-sized island was created from dredging activities and has transitioned into Legacy Island Park following public demand for green spaces. Plans for temporary structures, such as kayak launches and gazebos, are underway, with the park aiming to enhance recreational opportunities for local boating communities.
Historic Monkey Island
Location: Homosassa, Citrus County
Originally an unintended island for hazardous waste, Monkey Island now houses three spider monkeys. Recent renovations have improved facilities while keeping the charm of this quirky attraction alive, allowing viewers to engage with the animals via live streams.
Tarpon Island
Location: Palm Beach, Palm Beach County
As Palm Beach’s only private island, Tarpon Island features an expansive 30,000 square-foot home that recently sold for a staggering $150 million—Florida’s highest residential sale of 2024. This sale reflects the strong demand at the ultra-high end of the luxury market.
Bird Key
Location: Biscayne Bay, Miami-Dade County
Spanning four acres and serving as a critical sanctuary for birds, Bird Key has faced challenges from developers eager to transform it into residential properties. Environmental activists are actively monitoring its fate, underscoring the delicate balance between preserving natural habitats and real estate development.
Private islands in Florida offer a captivating blend of exclusivity, luxury, and potential for unique experiences, attracting both domestic and international buyers eager to claim their piece of paradise.
