Sotheby’s Expands Its US Luxury Property Footprint With Two Major Brokerage Deals

United States | September 10, 2026: Sotheby’s International Realty is strengthening its presence in some of the US’s most important luxury property markets by bringing two major affiliates under its company-owned brokerage network. The company has acquired ONE Sotheby’s International Realty and TTR Sotheby’s International Realty, expanding its direct presence across Florida’s east coast and the Washington, D.C. region.


Two Major Luxury Property Businesses Join the Network

ONE Sotheby’s International Realty operates across Florida’s east coast, including major luxury markets such as Miami, Fort Lauderdale and Palm Beach. TTR Sotheby’s International Realty covers the Washington, D.C. metropolitan area as well as Princeton and Lambertville, New Jersey.

Financial terms of the transactions have not been disclosed. Existing leadership teams will continue operating the businesses following the acquisitions.


Billions in Property Sales Behind the Deals

The scale of the two brokerages makes the acquisitions significant for the US luxury housing market.

ONE Sotheby’s International Realty recorded $6.85 billion in sales volume across 5,257 transaction sides in 2025, while TTR Sotheby’s International Realty generated $5.71 billion from 4,211 transaction sides, according to RealTrends Verified data.

Together, the brokerages represented more than $12.5 billion in residential transaction volume last year.

 


What It Means for Luxury Property Buyers and Sellers

Sotheby’s says advisors from both companies will gain access to expanded technology, marketing resources and international referral networks. The move could make it easier for luxury buyers and sellers moving between major markets such as New York, South Florida and Washington, D.C. to access the same brokerage platform.

For high-value property owners, a larger referral network can also provide access to a wider pool of domestic and international buyers.


Sotheby’s Pushes Further Into Key US Markets

The acquisitions fit Sotheby’s strategy of directly operating brokerages in major luxury and high-influence markets while continuing to work with independently owned affiliates globally.

The company now has more than 1,100 offices across 86 countries and territories, with nearly 170 company-owned brokerage offices in key US metropolitan and resort markets.

The expansion comes as luxury housing remains closely connected to wealth migration, second-home demand and the movement of high-net-worth buyers across major US markets. For property investors and sellers, the deal signals continued consolidation among large real estate brokerages and growing competition to control premium housing markets.
