The address 1 Star Island Dr sold for $55 million in July 2026, in an off-market deal — $20 million above the 2021 price. The transaction was recorded in public records and reported by The Real Deal and Profile Miami.
This is the fourth stop in the series on the 10 micro-markets that concentrate sales above $30 million in Miami-Dade — the ultra-luxury map, address by address.
What Star Island is
Star Island is a guard-gated artificial island on Biscayne Bay, in Miami Beach, with about 30 homes — created in 1922, in the same dredging project that produced Palm Island and Hibiscus Island. It is Miami's most famous address: one guardhouse, few homes, total discretion.
The anchor sale
The July 2026 off-market closing shows the strength of the market's most discreet segment: with no public listing, 1 Star Island Dr changed hands for $55 million — $20 million above the 2021 price. Discretion sells too.
The island's ultra-luxury track record
The record includes the following sales of $30 million or more on the island:
- 8 Star Island Dr — $75 million
- 1 Star Island Dr — $55 million (off-market, 2026)
- 43 Star Island Dr — $36 million
- 1 Star Island Dr — $35 million
- 37 Star Island Dr — $35 million
- 4-5 Star Island Dr — $33 million
- 13 Star Island Dr — $32.5 million
- 34 Star Island Dr — $30 million
Seven sales above $30 million in MLS history — plus the $55 million off-market anchor, which does not appear in the MLS.
Why it matters for buyers
Star Island is proof that Miami ultra-luxury runs at two speeds: the public market, recorded in the MLS, and the silent market of off-market deals among names that need no announcement. For buyers at this level, being on the island means joining the circuit where the biggest transactions happen away from the spotlight.
