Winner: Brookfield's $2.2B acquisition of Rouse Properties.

Why: In Brookfield's push for Blackstone status, the Canadian asset manager just keeps trucking along. The best part? Brookfield's buyout came from an unsolicited offer for the mall REIT, which Rouse considered, put to their special shareholder committee, and then approved. For that, Brookfield picks up February's Bisnow Deal Of The Month.

Brookfield has been on a tear recently, with CEO Bruce Flatt winning our January Player of the Month for his wheeling and dealing. And last month his firm bought out a German landmark without batting an eye.

And the oil plunge that slashed 70% of Blackstone’s Q4 profit isn't slowing the company down, it's just an opportunity—Brookfield is ready to swoop in on any office space left vacant from crude’s collapse.

Honorable Mentions:

• Dream Office $870M selloff: Canada's largest office REIT announced this selloff, and investors clearly were all for it, pushing shares up 14%, for its highest gain in seven years.

• Blackstone's $1.34B LA Office Tower Sale: Blackstone unloaded these four office towers, totaling 1.72M SF, to Douglas Emmett—one of the West Coast's largest landlords.
