"More opportunity, more new office building construction, more sublease opportunities and more attractive rents can be found in the 'burbs,'" Kaiser says. Sheer market size alone knocks out the CBD so far as office leasing volume is concerned, he says.

For example, the suburbs have 1.5 million sf of vacancy or 12% of availability, plus about 500,000 sf of sublease space. "This is compared to 625,000 sf of vacancy within the CBD, or 11% of availability, plus about 60,000 sf of sublease space," Kaiser points out.

Market size alone dictates most of the office deals for the rest of the year will be done outside the CBD, the broker maintains. For instance, the suburban market takes in Maitland, Winter Park, Lake Mary, University, Southwest Orlando and Southeast Orlando--"four times the size of Downtown," Kaiser says.
