The deal could cement the Internet company's move to mid-Market
Shorenstein Properties LLC, a prominent commercial real estate firm with longstanding ties to the San Francisco business and political establishment, is nearing a deal to acquire San Francisco Mart, the Market Street building that city officials hope will be the next home of Twitter, according to several people familiar with the deal.
... Steve Barker, an executive vice president at Studley, said the building’s valuation could vary widely due to its uniqueness and depending on its condition. But the acquisition could be a major boon, he said, if Shorenstein could list Twitter as an anchor tenant in a major real estate holding.
