Merrill Lynch sold a real estate unit.

The nation’s largest brokerage firm sold its 14-office commercial real estate brokerage division for an undisclosed price to Australia’s biggest real estate company, Hooker Corp. The sale was part of Merrill Lynch’s previously reported plan to divest certain real estate operations in order to focus on its basic securities businesses. The sale, however, did not include Merrill Lynch’s 400-office residential real estate brokerage network, relocation business and mortgage operation, which also are for sale.
