Michael O’Sullivan is a Hampton real estate investor who has focused his career on purchasing and selling foreclosed homes. He began with just $7,500, using that amount to buy the deed to his first property about 15 years ago. His company, Hampton Dream Properties LLC, is based in Remsenburg within the Town of Southampton and was founded during the challenging years following the 2008–2009 economic downturn and housing crisis. To gain the knowledge he needed to succeed, he attended three seminars with a Harvard attorney and eventually purchased 25 deeds to foreclosed homes in East Hampton and Southampton, New York.

Starting as an outsider in the Hampton community, he worked tirelessly to earn trust and establish his business. Over the years, he completed more than 200 transactions, including over 30 settled foreclosures in East Hampton alone. Several of his clients became millionaires through their work with him. By 2022–2023, his company had grown to generate $6 million in revenue. Among his many accomplishments was a foreclosure settlement that allowed a client to resell a property and earn a $500,000 net profit. That same client later secured a $700,000 line of credit against the property, enabling him to maintain ownership while creating income from three rental units. In another case, he personally paid the bank to stop a foreclosure, allowing a friend’s mentally challenged father to remain in his home for two years before the property was eventually resold.

He works with skilled attorneys to manage foreclosure settlements, including one lawyer who authored the Foreclosure Abuse Prevention Act (FAPA), which became law in December 2022. This legislation protects homeowners from unfair practices by mortgage lenders, such as restarting foreclosures or resetting limitation periods through procedural loopholes.

He is also developing the land he purchased several years ago in Mastic, New York, a community once known for its high crime rates but now undergoing government-backed revitalization. He owns a significant amount of property there, and national chains such as Taco Bell and Buffalo Wild Wings are in negotiations to open restaurants on his sites.

Outside of real estate, he has a strong passion for music. He produced an album called Liquid Jazz at Sonic Studio, secured a record deal with Mystic Music in New York, and was listed in a Washington, D.C. registry. The album has been played on every jazz college station across the United States.

A native New Yorker, he volunteered at ground zero after the September 11 attacks and supports the Tunnel to Towers Foundation, which assists 9/11 first responders, veterans, and their families. He was born in Brooklyn and raised on Long Island, where he served as an altar boy at Saint Rose Lima Church in Massapequa for five years. He is a member of the Ancient Order of Hibernians, where he earned the Major Degree, demonstrating his commitment to the organization’s principles of Friendship, Unity, and Christian Charity. He attended Nassau Community College and briefly studied at New York University.

Michael O’Sullivan of Hampton continues to expand his real estate ventures, give back to his community, and follow his passion for music and service.
