Commercial Real Estate Brokerage Jones Lang LaSalle has good news for Boston in its latest report.

First, Boston’s commercial real estate market is going to be one of the first to come back after the beat-down last year, according to its Boston Marketscape Newsletter. Office vacancies had been headed upwards by about 6 percent since February 2008, but the positive news is that they were merely were flat over the summer.

Also in the report: Boston gained its first new office tower in five years with the completion of Two Financial Center. Rents are stopping their downward plunge in downtown Boston, but they’re still about 25 percent lower than their peak.

In Cambridge, total vacancies rose, thanks to IBM’s lease expiration at 1 Rogers St. And tenants in suburbia are still in the driver’s seat as empty commercial space rose outside the city limits.
