ONE Sotheby's International Realty acquires Sotheby’s International Realty

ONE Sotheby's International Realty has expanded its reach into New Jersey by acquiring Callaway Henderson Sotheby's International Realty. The acquisition underscores ONE Sotheby's intent to broaden its geographic footprint beyond its established base in Florida. While the financial terms remain undisclosed, the move strategically enhances the brokerage's presence in the Northeast.

Callaway Henderson Sotheby's International Realty, created from the 2012 union of two longstanding family businesses, brings with it a workforce of 135 agents operating out of two offices. These offices serve five counties in central New Jersey. The New Jersey firm was notably active in the luxury real estate market, reporting nearly $800 million in closed sales in 2025. ONE Sotheby's already operates 30 offices in Florida, establishing a luxury real estate expertise corridor from the Southeast to the Northeast.

The acquisition is anticipated to augment ONE Sotheby's market position significantly, providing access to a robust client base and an established operational framework within New Jersey. According to Daniel de la Vega, the president and CEO of ONE Sotheby's, the family-based legacy and esteemed reputation of Callaway Henderson align well with ONE Sotheby's focus on high-end properties. Jud Henderson, a managing member at Callaway Henderson, considers the acquisition an evolution for his family's business and an opportunity to elevate their brand within the broader Sotheby's network.

The acquisition comes amid a broader trend of real estate brokerages increasing their market footprints through strategic acquisitions and office expansions. In a competitive market, firms like The Agency and Decode Real Estate are also expanding their offerings and locations, seeking to capture interest from luxury buyers in both established and emerging locales. The entrance of ONE Sotheby's into New Jersey could heighten competitive pressures in the local market, particularly for firms targeting high-net-worth individuals and the luxury real estate segment.

With Aileen Konzelmann appointed as the new president of ONE Sotheby's New Jersey operations, the company aims to integrate these new assets and leverage the established business knowledge. Konzelmann, who brings extensive experience from Weichert Premier and Marriott International, is expected to spearhead growth initiatives in the region. The success of this acquisition will depend on effectively merging operations and capitalizing on the synergies between the two Sotheby's affiliates. The focus will also be on maintaining client relationships and fostering brand loyalty in an increasingly competitive market landscape.
