Mark Zuckerberg Just Set a Miami Real Estate Record With A $170 Million "Billionaire Bunker" Mansion Purchase

Mark Zuckerberg just set a new benchmark for luxury real estate in Miami.

The Meta CEO and his wife, Priscilla Chan, quietly closed on a $170 million mansion on the ultra-exclusive Indian Creek Island, a purchase that now ranks as the most expensive home ever sold in Miami-Dade County. The deal eclipses the previous record by tens of millions of dollars and further cements Indian Creek's reputation as one of the most expensive and private residential enclaves in the United States.

The home is still under construction, but plans call for a sprawling waterfront compound packed with extravagant amenities. And at $170 million, the purchase also places Zuckerberg's new residence among the priciest homes ever sold anywhere in America.

The $170 Million Mansion

The property sits on roughly two acres at 7 Indian Creek Island Road, one of only about 40 waterfront estates located on the tiny private island in Biscayne Bay.

When completed, the limestone mansion is expected to span approximately 30,000 square feet and include nine bedrooms along with a long list of luxury features. Early plans for the home include:

• A private dock overlooking Biscayne Bay
• A resort-style swimming pool
• A full gym and wellness area
• A hair salon and massage room
• A home theater
• A library with a hidden passageway
• A 1,500-gallon aquarium

The home was designed by luxury architect and designer Ferris Rafauli, whose firm handled the architecture, interiors, and landscaping.

Construction began several years ago after the sellers purchased the site in 2020 for just over $30 million. The property was listed for $200 million in late 2025 before ultimately selling to Zuckerberg and Chan for $170 million. Here is a video tour:

Who Sold the Property?

The sellers were Dr. Aaron Rollins, a cosmetic surgeon known for treating celebrity clients, and his wife Marine Rollins, a real estate agent.

The couple spent several years designing and building the home before putting it on the market. If the roughly $30 million land purchase and construction costs are taken into account, the sale likely still represents a massive profit.

The listing was handled by Danny and Jill Hertzberg of Coldwell Banker Realty. Zuckerberg and Chan were represented by Brett Harris of Bespoke Real Estate.

Inside Miami's "Billionaire Bunker"

Indian Creek Island is one of the most exclusive residential communities in the United States. Often nicknamed "Billionaire Bunker," the island has roughly 40 homes, all located directly on the water and arranged around a private 18-hole golf course.

The island operates its own police force and is accessible only through a single guarded bridge, offering residents an unusually high level of privacy and security.

Over the past decade, the enclave has attracted an increasingly high-profile roster of residents, including Tom Brady, Carl Icahn, and several hedge fund billionaires and tech executives.

The surge of ultra-wealthy buyers moving to South Florida accelerated dramatically during and after the COVID-19 pandemic, when many executives relocated from high-tax states like California and New York.

A Record-Breaking Miami Sale

At $170 million, Zuckerberg's purchase now stands as the most expensive residential sale ever recorded in Miami-Dade County.

The previous record holders were far lower. In recent years:

• Billionaire developer Vlad Doronin sold a Star Island estate for $120 million
• Hedge fund billionaire Ken Griffin paid $106.9 million for Adrienne Arsht's Coconut Grove property in 2022

Despite the record, the purchase is not the most expensive home ever sold in Florida. That distinction belongs to a $225 million waterfront estate that traded in Naples.

Nationally, the biggest residential deal on record remains Ken Griffin's roughly $238 million purchase of a New York City penthouse in 2019.

Part of a Larger Billionaire Migration

Zuckerberg already owns several large properties around the country, including estates in Palo Alto, Lake Tahoe, and Hawaii.

His purchase in Miami also reflects a broader trend that has reshaped South Florida's real estate market in recent years. Wealthy buyers from California, New York, and Chicago have increasingly relocated to Florida, drawn by the state's lower taxes and business-friendly policies.

Some real estate agents say the migration could accelerate even further if California moves forward with proposals for a one-time wealth tax on residents with net worths above $1 billion.

Whether or not tax policy ultimately plays a role, Zuckerberg's $170 million purchase highlights just how dramatically Miami's luxury real estate market has evolved.

A decade ago, a $50 million home sale in the city was considered extraordinary. Today, the record stands at $170 million. And it may not hold for long.
