In the battle for Chicago real estate dominance, @properties Christie’s International Real Estate has the dollar volume — but Jameson Sotheby’s International Realty has the price tag.
Jameson, led by CEO James Feurer, had the largest average deal size, of just over $913,000, among Cook County’s top residential brokerages this year, according to an analysis by The Real Deal that looked at on-market closed home sales in Cook County from October 2024 to October 2025.
Jameson’s average far exceeds the average of all the top 20 agencies in the region, which came in at about $573,000 this year.
However, while Jameson had the highest average deal size this year, the firm ranked fifth in terms of total sales dollar volume, bringing in just under $2 billion worth of sales across about 2,200 deals.
Meanwhile, @properties Christie’s International Real Estate took the top slot in terms of sales dollar volume. The firm, which about a year ago was acquired by Compass, closed just over 10,700 deals that totaled $7.9 billion.
But @properties’ average deal size worked out to roughly $733,000 — good for second place.
Compass, for its part, took the bronze-medal place in terms of its average transaction size, which was nearly $710,000. The firm’s overall deal dollar volume of $5.5 billion was second best in the county this year.

In 2025, the top 20 brokerages in Cook County handled about $28.6 billion in sales dollar volume across nearly 50,000 transactions, combined. Both figures were lower than last year, when the top 20 firms closed $29.3 billion over more than 57,100 deals.
Cook County’s residential market was marked by acquisitions in 2025. Compass not only took over @properties, but it also is in the midst of acquiring Anywhere Real Estate. Should the deal close, the combined firm would be the largest in the country.
Baird & Warner (fourth by sales dollar volume) also took over Dream Town Real Estate (eighth by sales dollar volume) this year, in a move that united two of Chicago’s top independent brokerages.
