An affiliate of Miami-based Azora Exan acquired 149 Newbury St. in Boston from the property’s developer, Chicago-based L3 Capital, for $101 million, reported the Boston Business Journal. The per-square-foot price of $2,321 for the five-story mixed-use property was higher than any other Boston commercial real estate transaction since 2000 other than the Mandarin Oriental in Back Bay and The Alyx at Echelon Seaport, the Business Journal reported, citing research from Hunneman.
