Market heats up for office towers
Sales in Boston point to emergence from downturn
Boston’s office towers are again hot commodities after several years of slow sales, a sign the city’s economic recovery is gathering speed as businesses expand and investors swarm opportunities to snap up trophy properties. Eleven buildings changed hands in the city last year, a nearly fourfold increase from 2010, according to the commercial real estate firm Jones Lang LaSalle. Among the towers sold were the 40-story Exchange Place building on State Street and 33 Arch Street - deals that totaled nearly $1 billion.
