Sotheby’s International Realty acquired its two largest franchises by sales volume this week, ONE Sotheby’s International Realty and TTR Sotheby’s International Realty.
Together, the two firms closed $12.56 billion in sales in 2025, and both are now company-owned instead of independently operated. The company announced the deal Wednesday, September 9. Financial terms weren’t disclosed.
Sotheby’s Brings Its Two Largest Franchises In-House
The deal gives Sotheby’s greater control in three influential East Coast luxury corridors: Florida’s east coast, the Washington, D.C., metro and parts of New Jersey.
ONE Sotheby’s recorded $6.85 billion in 2025 sales volume across 5,257 transaction sides, according to RealTrends Verified. The Miami-based firm has nearly 1,400 advisors and stretches along Florida’s east coast, with an additional presence in Princeton and Lambertville, New Jersey.
TTR Sotheby’s generated another $5.71 billion across 4,211 sides. The brokerage has close to 700 agents serving the greater Washington, D.C., area.
Together, the firms accounted for more than 9,400 transaction sides last year.
Philip White, president and CEO of Sotheby’s International Realty, stated:
“This is a strategic investment in the strength of Sotheby’s International Realty and in the visionaries who represent our brand. ONE Sotheby’s International Realty and TTR Sotheby’s International Realty have built high-performing businesses grounded in strong leadership, deep market expertise and an unwavering commitment to their clients.”
Local Leadership Stays in Place
Sotheby’s is changing the ownership structure without replacing the people running either company.
ONE Sotheby’s Executive Chair Mayi de la Vega and President and CEO Daniel de la Vega will remain in their roles. de la Vega described the decision this way:
“Our vision was to create a brokerage defined by exceptional people, a strong culture and a shared commitment to excellence. This milestone is a testament to our collective achievements and an exciting opportunity to build upon our success with an even greater platform for growth.”
TTR Executive Chair Mark Lowham, CEO David DeSantis and President Derrick Swaak will also continue leading the D.C.-area firm, while founders Jonathan Taylor and Michael Rankin will retain leadership positions. Lowham explained:
“By bringing together our respective strengths, we’re not only expanding our reach beyond the greater Washington, D.C., area, we’re elevating what’s possible in luxury real estate. Together, we are uniquely positioned to bring greater expertise, innovative technology, and an even higher level of service to our advisors and their clients, delivering exceptional results in an increasingly dynamic marketplace.”
The newly acquired firms join Sotheby’s existing company-owned operations in markets including New York City, Los Angeles, Houston, Denver and Park City, Utah. The brand closes $182 billion in annual sales with 1,100 offices spanning across 86 countries and territories.
What This Means for Agents
Sotheby’s International Realty, the brand and its company-owned brokerage arm, belongs to Anywhere Real Estate. Compass completed its acquisition of Anywhere in January 2026, so Anywhere’s brands, Sotheby’s included, now operate beneath Compass International Holdings, the world’s largest residential real estate brokerage.
The acquisition shows where brokerage competition is moving. Consolidation is no longer only about adding agent count. It is about owning the platform, controlling more listing and client data, and creating referral networks that keep business inside the same ecosystem.
Local brands and leadership still matter. Sotheby’s decision to keep both management teams intact makes that clear. The difference is that those teams will now compete with the resources, and the expectations, of a much larger company behind them.
