The Sotheby’s International Realty's network

It all began in London in 1744, when Sotheby’s, the world’s oldest and most prestigious auction house, was founded. It has been renowned for over 250 years. She federates around her a network of enthusiasts and collectors always on the lookout for exceptional goods.

So it was only natural that the real estate sector should be created in 1976: Sotheby’s International Realty® was born.

The network quickly became the world leader in prestige real estate. With 26,400 agents, we now have more than 1,100 branches in over 83 countries. 

The network’s presence in the main international markets ensures optimum visibility for your property not only in the agency network, but also on the Internet via the worldwide website and related partner sites.

These include James Edition, The Wall Street Journal and The New York Times. More than 52 million visitors to SIR.com in 2023.
