SAN FRANCISCO-Those who follow @GlobeStcom on Twitter and @GlobeStLIVE may have seen a post teasing the announcement, but GlobeSt.com has learned that Wells Real Estate Investment Trust II Inc. has acquired 333 Market St., a 33-story office tower in the heart of San Francisco’s Financial District. The seller of the class-A asset was the Korean Federation of Community Credit Cooperatives

Wells REIT II was represented internally by Keith Willby, senior vice president of capital markets. Currently, the Wells REIT II portfolio includes 82 office buildings in 20 states and Washington, DC, and one international property, collectively covering approximately 21 million square feet. 

Wells REIT II closed to new investments on June 30, 2010. The firm could not disclose any further information about the purchase at this time. The 657,000-square-foot building, constructed in 1979, has undergone over $80 million in capital investments and tenant improvements over the past eight years.

The building is fully leased to Wells Fargo Bank NA. “We are pleased to add this trophy-quality asset to the Wells REIT II portfolio,” says Nelson Mills, president of Wells REIT II, in a prepared statement. “This strategic acquisition in one of the nation’s premier office markets helps to further improve the institutional-quality of the portfolio overall.”

While parties involved could not add further details to the story, an unidentified source not involved in the deal put the price above $400 million.
