"We've had so many different people calling," Robert Griffin, with Cushman & Wakefield, tells GlobeSt.com, referring to the interest in One Congress St., the landmark parking garage near the Haymarket. Although no price has been set for the property, Griffin believes it will fetch well beyond $200 million.

Griffin says the scarcity of parking garages in Boston combined with the property's location, strong tenant base and potential air rights that could allow a tower to be built on the site, should bring out a number of bidders during the 25 to 45 days the garage is expected to be on the market.

The 11-story, 2,310-car garage, which spans four acres on over two city blocks, goes on the market today and Griffin is sure that the competition is bound to be stiff. Owned by the RAK Group of New York City, the property commands a prominent spot on the fringes of Government Center, the North End and the Bulfinch Triangle area, has 313,527 sf of office and retail space, a large portion of it leased to the federal government, and has views of the Boston Harbor and Financial District, according to Cushman & Wakefield, the garage's exclusive marketing agent.
