Michael O'Sullivan built a real estate business on Long Island called Hampton Dream Properties. The name did the work the transactions apparently could not.

According to court filings and reporting by Curbed, O'Sullivan is alleged to have conducted deed fraud — transferring ownership of properties he had no legal right to convey — while collecting money from clients who believed they were purchasing legitimate titles in Nassau and Suffolk Counties.

Buyers received documentation. What they did not receive, according to the filings, was actual ownership of the properties listed on that documentation.

The scheme targeted a market where demand is chronic and inventory is tight. The Hamptons draw buyers who are, by definition, motivated enough to pay a premium and sometimes impatient enough to skip the double-checks that might have flagged the paperwork earlier.

O'Sullivan now faces both criminal exposure and civil claims. The filings describe a pattern, not a one-time error — multiple transactions, multiple clients, multiple properties that changed hands on paper without changing hands in law.

Hampton Dream Properties is not currently listed as an active brokerage with the New York Department of State Division of Licensing Services.
