U.S. Realty Advisors has purchased two Hopkinton properties from an affiliate of RREEF for $31.5 million.

Cushman & Wakefield brokered the sale of 68 Elm St. and 5 Parkwood Drive, and arranged acquisition and expansion financing for the buyer.

The buildings total 198,000 square feet of office space and R&D space that serves as the headquarters of Caliper Life Sciences, a subsidiary of technology firm PerkinElmer. 

Expansion plans for the property will add 61,000 square feet to the campus including 40,000 square feet of office and 21,000 square feet of warehouse space.

Cushman & Wakefield’s capital markets team of Robert Griffin, Edward Maher and Matthew Pullen, together with leasing specialist J.R. McDonald, exclusively represented the seller, an affiliate of the RREEF Funds.

The acquisition and expansion financing was arranged by Jay Wagner of Cushman & Wakefield’s equity, debt and structured finance practice.
