ASB Real Estate Investments has secured $63 million in financing for two office buildings in Boston’s Seaport District. Totaling 217,000 square feet, the buildings are owned by ASB’s Allegiance Fund in a joint venture with Lincoln Property Company. Located at 320 and 333 Summer Street, the 10-year, 3.65 percent, fixed-rate loan was sourced by Holliday Fenoglio Fowler with The Hartford Financial Services Group. The properties feature loft-style office space that is 97 percent leased to LogMeln, a PC data systems management firm, which is merging into a subsidiary of Citrix. The buildings are situated directly across from each other along Summer Street just across the Fort Point Channel from South Station and Boston’s Financial District.
