John Carbone

John began his real estate career a decade ago, just before earning his degree with honors from New York University’s College of Arts and Science. Since then, he has directed and participated in more than $2 billion in complex transactions spanning luxury resales, high-end rentals, and new development sales, earning the confidence of discerning sellers and buyers throughout Manhattan's most coveted addresses.

A recognized specialist in Upper East Side cooperative buildings, particularly along Fifth and Park Avenues, John has built deep expertise navigating the nuanced requirements of the city's most prestigious co-op boards and properties. He has represented properties across all asset classes and price points, including three full-floor apartments at 860 Park Avenue, an 18.5'-wide Lenox Hill townhouse, a Charles Gwathmey-designed pied-à-terre at The Sherry-Netherland, a full-floor SoHo loft, a duplex penthouse in Chelsea, and a Rosario Candela masterpiece in a distinguished Sutton Place South cooperative, to name a few. He is also known for maintaining an extensive network of off-market opportunities that rarely, if ever, trade publicly.

As an Associate Broker and Global Real Estate Advisor with Sotheby's International Realty, John brings a rare combination of deal-making expertise and strategic leadership. Over the last five years, he has identified and developed elite brokers, building and managing teams responsible for more than $300 million in transaction volume annually, establishing a standard for both performance and client service.

His approach to negotiation is direct yet collaborative, while his marketing seamlessly integrates rigorous market analysis with elegant, narrative-driven storytelling. Known for identifying emerging trends before they reach the headlines, John delivers clarity and actionable intelligence to clients navigating New York's complex luxury landscape.

He is a member of the Real Estate Board of New York and speaks English and German.
