Sotheby’s Expands with New Jersey Acquisition

The real estate industry is seeing significant movement, with several brokerage firms making notable announcements. ONE Sotheby’s International Realty has acquired Callaway Henderson Sotheby’s International Realty, a New Jersey-based firm, expanding its reach into the Northeast. This move adds 135 agents and two offices to ONE Sotheby’s existing 30 Florida offices.

Callaway Henderson, founded in 2012 through the merger of two family-run firms, reported nearly $800 million in closed sales in 2025. The acquisition creates a “powerful corridor of luxury real estate expertise” between Florida and New Jersey, according to the company. They see this as a strategic expansion.

Daniel de la Vega, ONE Sotheby’s president and CEO, praised the Callaway and Henderson families for building an “exceptional business” with “decades of leadership, integrity, and trusted market expertise.” Jud Henderson, managing member at Callaway Henderson Sotheby’s, called the union “a defining evolution for our family business.” The company is optimistic about the future.

Aileen Konzelmann has been named president of ONE Sotheby’s International Realty’s New Jersey operations, bringing 23 years of experience with Marriott International to the role. She previously led Weichert Premier’s Moorestown and Haddonfield offices, and they expect her to leverage this experience in her new position.

In other news, The Agency has expanded its Nevada footprint with the launch of The Agency Incline Village, its fourth office in the state. The new office will be led by Managing Partners Zar Zanganeh and Jenna Rose Madrid, who bring experience in the Incline Village and Maui, Hawaii, luxury markets, and are expected to drive growth in real estate technology.

Mauricio Umansky, The Agency Founder and CEO, said Incline Village is a market that “earns its reputation every single day,” with Nevada’s tax advantages, Lake Tahoe’s natural beauty, and a four-season lifestyle attracting sophisticated buyers. The area has become one of the most sought-after second home and luxury retreat markets in the country, and it is likely to continue growing.

Decode Real Estate has launched Decode Hamptons, expanding the New York City brokerage’s presence into the East End luxury market. The new division will be led by Nastassja Balick Coppers, who joins Decode after several years at Compass, and they expect her to bring valuable expertise to the role.

Decode Hamptons will focus on sales, acquisitions, and estate advisory services for buyers seeking primary residences, second homes, and long-term investments. Founder Danielle Nazinitsky said the expansion reflects growing overlap between clients investing across both New York City and the Hamptons, and they are adapting to meet the changing needs of their clients.

Nazinitsky praised Balick Coppers as the “ideal leader” to bring Decode’s client-first approach to the East End, with a specialization in advising high-net-worth and international clients on luxury properties, and the company is confident in her ability to drive success.

Christie’s International Real Estate has also made a move, landing in Los Cabos through a new affiliate, Oceanside Real Estate. The 35-agent firm, now operating as Christie’s International Real Estate | Oceanside Los Cabos, boasts annual sales of $110 million and specializes in luxury, pre-construction sales, resort golf communities, and residential developments, and they are expected to be a major player in the market.

CIRE President Gavin Swartzman said the Oceanside Los Cabos team “embodies the best qualities of a local independent operator,” with a deep commitment to the community and clients. Meanwhile, Michael Saunders & Company has welcomed luxury waterfront specialist Lysette Ketterer to its St. Petersburg, Florida, office, bringing the location’s agent count to 20, and they expect her to strengthen the company’s presence in the region with her leadership skills.

Ketterer, formerly with Century 21, has been serving the Southwest Florida market for over a decade and is expected to drive growth with her “personalized service and results-driven mindset” and ability to combine data-driven insights with intuitive market knowledge, and the company is optimistic about her future with them.

These moves reflect the ongoing evolution of the real estate industry, with firms expanding their reach and expertise to meet the demands of a changing market, and they are likely to continue adapting to remain competitive, with companies like Opendoor seeing strong performance under new leadership.
