During down market, trade up

Brokers say the down commercial market is a good time for companies to trade up to better buildings and better built-out spaces. A large downtown block of space that’s available and fully built-out is Citigroup’s 1.2 million square feet at 125 Broad Street, at South Street. Citigroup notified landlord Mack-Cali Realty Trust that it won’t be renewing its space there at the end of 2009, and can make space available sooner as some of the floors are sitting empty.
