Fisher Island Real Estate: Florida’s Most Expensive Neighborhood Surpasses Silicon Valley

Fisher Island real estate now ranks as the most expensive neighborhood in the United States, surpassing Silicon Valley’s Atherton after eight years at the top. The private Miami Beach enclave, reachable only by ferry or yacht, recorded a median home price of $9.5 million as of September 30. The data comes from PropertyShark.

Florida’s Ultra-Luxury Leader

Home to around 700 households, Fisher Island offers private marinas, a golf course, and resort-style amenities within minutes of Miami Beach. Its exclusivity and location make it a prime destination for global buyers.
Although Indian Creek Island, known as the “Billionaire’s Bunker,” hosts residents like Jeff Bezos and Tom Brady, its ZIP code includes nearby, lower-priced properties. This factor helps Fisher Island’s figures rise even higher.

California Still Dominates Luxury Living

Even with Fisher Island’s win, California remains dominant in luxury real estate. The state holds 73 of the nation’s 100 priciest ZIP codes, or 120 when including ties.
By contrast, Florida claimed only two entries—Fisher Island and Boca Grande, a Gulf Coast retreat.
In the Northeast, the trend shifted slightly. Tribeca in New York ranked 20th with a $3.7 million median, down from $4.1 million in 2017. Meanwhile, Connecticut’s Fairfield County added several top ZIPs as Manhattan’s presence declined.

Luxury Prices Reach New Heights

The entry bar for elite ZIP codes is now $5 million, up from $4.4 million last year. Even the 100th-ranked ZIP, Fremont, California, recorded a $2 million median.
Across the country, record highs continue to appear:

• Alpine, NJ: up 31% to $4.35M

• Deal, NJ: up 20% to $3.55M

• Paradise Valley, AZ: reached $3.5M, a new state record

• Lake Tahoe, NV: saw two communities achieve fresh peaks

Additionally, four new locations joined the national top 100: Snowmass (CO), Kilauea (HI), Sea Island (GA), and Sullivan’s Island (SC). Each reinforces the appeal of island and mountain lifestyles among ultra-wealthy buyers.

Florida’s Luxury Market on the Rise

The growth of Fisher Island real estate mirrors Florida’s surge in the high-end housing market. Rising demand, tax incentives, and limited supply continue to push values higher.
Florida now rivals California as a destination for global investors seeking privacy, sunshine, and strong property value appreciation.
