In the Bay Area, Sotheby’s International Realty takes the cake in terms of average home sale size.
The average deal at Sotheby’s this year came in at $2.4 million, the highest among the top 20 residential brokerages in the region by deal volume, according to an analysis of The Real Deal’s annual top brokerage ranking. (For the list, TRD counted buy- and sell-side residential deals — excluding off-market transactions — from May 15, 2024 to May 15, 2025 in Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano and Sonoma counties.)
Sotheby’s ranked seventh on TRD’s list by its total deal volume, as the firm brought in more than $2.7 billion worth of business across 1,125 deals over the past year.
The brokerage with the second-highest average deal size was another Sotheby’s offshoot, Golden Gate Sotheby’s International. That branch, which placed sixth in this year’s transactions-volume ranking, had an average deal size of about $2.2 million.
The top-ranking firm by deal volume this year was Compass, which dominated the competition with $27.7 billion in sales across 14,751 transactions. That works out to an average of $1.9 million per deal — the sixth-highest average among the top Bay Area firms.

Over the past year, the Bay Area’s residential scene has held steady. Inventory has risen in the region, and buyers are snapping up homes in under a month. Prices are also elevated.
In July, the median sale price was $1.3 million, relatively stable compared to the year before and well above California’s statewide median of $884,050, according to data from Norada Real Estate Investments.
However, there are county-to-county differences within the region. For instance, the median price in Napa County plunged by 12.1 percent compared to the same time last year. Meanwhile, the median price in Marin county ticked up by nearly 2 percent, according to Norada.
