Financier Mark Marcello purchased a Palm Beach estate in the Mar-a-Lago Security Zone for $36 million, according to records dated March 11. The property, located at 160 Clarendon Avenue, was acquired through Marcello’s Florida-based entity, 150 Clarendon Avenue LLC, from sellers John and Marilyn Breyo. Lawrence Moens of Lawrence A. Moens Associates represented both parties in the transaction.
The sale highlights ongoing interest in high-value real estate within the Mar-a-Lago Security Zone, an area known for its heightened security measures when former President Donald Trump is present at his private club and residence nearby. Agents have pointed to increased security and proximity to influential figures as key attractions for buyers in this neighborhood since the 2024 election.
Marcello is described as a longtime West Palm Beach resident and partner at Windsor Capital Partners, an investment firm founded by his father. Records indicate he previously bought a waterfront home at 5009 South Flagler Drive for $1.8 million in 2007.
John Breyo was formerly an executive at Ayco Corporation, a personal financial counseling company that was acquired by American Express in 1983 and later by Goldman Sachs in 2003. Ayco continues to operate as part of Goldman Sachs’ wealth management division.
The Breyos originally purchased the Clarendon Avenue estate for $2.3 million in 2000. Built on a 1.5-acre lot in 1999, the mansion spans approximately 8,900 square feet and features five bedrooms, six bathrooms, two half-bathrooms, a gym, and a pool. The property was first listed for $55 million during the peak of Palm Beach’s pandemic-era market boom but saw significant price reductions before selling.
Recent sales activity on Clarendon Avenue includes real estate investor Robert Miller and his wife Linnette Miller acquiring another home on the street for $25 million last month. Price reductions have played a role in facilitating deals this season; earlier this month, an oceanfront historic home designed by architect Marion Sims Wyeth sold for $28 million after being discounted by $10.7 million from its previous listing price.
