In a released statement, Arthur Sonnenblick, manging director at Sonnenblick-Goldman said, "Ten Post Office Square is an outstanding investment for Walton Street Capital as the Boston metropolitan area office market is experiencing the strongest rental market and the highest occupancy rates for office space in the past several decades."

The property includes two 13-story office buildings with approximately 437,200 sf of office space. The buildings are currently 96% leased to a variety of companies including Boston Private Bank, Dow Jones & Company, Capital One Financing Corporation, Interactive Data Corp. and Land Vest."We like the Boston market," Jeff Quicksilver, principal at Walton Street capital tells GlobeSt.com. "From a real estate fundamental perspective it's a terrific asset and it fits our strategy as a value-added investor."

This is not Walton's first foray into the Boston market. Recently it bought one Boston Place. Over the past five years, the company has invested over a billion dollars in equity with a gross acquisition cost of two and a half billion dollars buying property in major cities across the US such as NY, PA, Seattle, SF, Chicago and Miami.
