Longstanding New York City brokerage Coldwell Banker Hunt Kennedy is closing its doors, according to multiple sources familiar with the company. The 21-year-old, 214-agent company — Manhattan’s sixth largest, according to a recent survey by The Real Deal — will cease operations within 60 days, the sources said. What’s left of the company is believed to be on the auction block and priced at around $5 million. But because Coldwell Banker Hunt Kennedy — including its luxury marketing division Coldwell Banker Previews International — allegedly owes some $12 million, the price would presumably go towards its debt. It’s not the first Manhattan company to close its doors in a rocky market. Last month, boutique residential real estate brokerage JC DeNiro & Associates announced it would close its doors. But Coldwell Banker Hunt Kennedy is by far the largest Manhattan company to close thus far, with offices at 555 Madison Avenue, 329 Columbus Avenue, 64 West 21st Street, and 155 Seventh Avenue in Park Slope.
