125 Summer Street

Toronto-based Oxford Properties Group has secured a $150 million first mortgage on 125 Summer St. in Boston.

The Summer Street property is a 475,303-square-foot office tower acquired by Oxford Properties Group in September for $242.5 million from Blackstone’s Equity Office division.

HFF represented Oxford to secure the fixed-rate loan through Guggenheim Commercial Real Estate Finance LLC. HFF’s Riaz Cassum, John Fowler and Patrick McAneny led the HFF debt placement team.

Located on the Rose Fitzgerald Kennedy Greenway a block from South Station, the 22-story office tower is leased to tenants including Burns & Levinson, Sunstein Kann Murphy and Gartner. The property includes a 273-space underground garage, daycare center and Starbucks.

“125 Summer is an institutional quality asset that is poised to benefit from its location in the Financial District, an area of the city that has seen an influx of more than 3,000 residents and is currently undergoing a transformation into a 24/7 neighborhood,” Cassum said in a statement.
