Located on a half acre on 19th Street off Route 66, Potomac Tower boasts more than just a prime location literally a stone's throw from the District. The IM Pei-designed office building, which ascends 19-stories, brings the new owner the added convenience of being 100% occupied by less than 10 tenants. Investment firm Friedman Billings Ramsey Group Inc. keeps its headquarters in the building, and along with Northrop Grumman and Strategic Investment Partners Inc., accounts for 70% of the total leasable space.

Other features include a 165,000-sf parking facility that spans eight levels, five of which are above-grade. And that wasn't all that appealed to the buyer. "Distinctive architecture and unmatched views have established Potomac Tower as one of the Washington, DC area's top-tier and most sought-after assets," notes Ric Clark, Brookfield Properties president & CEO.

Real estate industry watchers can expect to see more large deals involving Brookfield Properties in the near future. "We remain interested in the Washington, DC market," Melissa Coley, Brookfield Properties vice president for investor relations and communications, tells GlobeSt.com. "There's an enormous amount of competition, but looking at the fact that we've acquired three great buildings in the last nine months is a testament to our tenacity. We continue to look for trophy assets that will complement our portfolio of premiere properties."
