Billionaire developer Vlad Doronin has sold his waterfront estate on Miami Beach’s exclusive Star Island for $120 million, setting a new record for the most expensive home sale in Miami-Dade County.

The 2.5-acre property at 26 Star Island Drive was purchased by Constellation Drive LLC, a Delaware entity led by businessman Michael Ferro. Doronin, through his company Garden Islands International LLC, originally acquired the estate in 2009 for $16 million from retired basketball star Shaquille O’Neal.

The 22,000-square-foot mansion features six bedrooms, seven bathrooms, a pool, a tennis court, and a private dock. This sale reinforces Star Island’s status as one of the most coveted addresses in South Florida’s ultra-luxury real estate market.
