Keller Williams level with them, Compass far behind
Keller Williams has almost as many, 253 agents, 30.6% of the branded rows and 2.3 times its Illinois share; kw.com is on 247 rows.
The firms that are big in Chicago are not big here: Compass is 5.2% of Naperville's branded agents (11.3% statewide), Berkshire Hathaway HomeServices 3.4% (10.3%) and HomeSmart 3.9% (8.3%).
94% of the 833 rows give a phone, and 12% a free-mail address.
Two Coldwell Banker companies under one name
Coldwell Banker carries 256 Naperville agents, 31% of the branded file against 18.5% across Illinois, and the name covers two separate companies: Coldwell Banker Realty (189) and Coldwell Banker Real Estate Group (67).
The inboxes tell them apart: Coldwell Banker Realty's agents write from cbrealty.com (99 rows) and cbexchange.com (90), Coldwell Banker Real Estate Group's from coldwellhomes.com (52).
Coldwell Banker Real Estate Group, the coldwellhomes.com company, is family-owned: in 1984 its founder bought Robert J. Honig & Associates and grew it into what it calls the largest Coldwell Banker affiliate in the world, today with nearly 60 offices across Wisconsin, Illinois, Indiana and Michigan (Coldwell Banker Real Estate Group).
