San Francisco-based Digital Realty Trust Inc. intends to purchase a three-property data center portfolio, which includes property in Bedford and Needham, for approximately $375 million.

The collection of property, known as the New England Portfolio, is comprised of a total of approximately 550,290 square feet. It consists of 55 Middlesex Turnpike in Bedford, 128 First Ave. in Needham and 60-80 Merritt Boulevard in Trumbull, Conn.

The facilities have been renovated to modern data center standards in the last four years, according to a statement.

The purchase price will initially be funded with borrowings under the company’s revolving credit facility, according to a statement.

"Upon closing, the addition of these high quality, mission critical datacenter facilities will significantly expand our footprint in the important New England market," said Scott Peterson, senior vice president of Acquisitions for Digital Realty Trust. "The portfolio is leased to a diverse roster of 36 tenants in various industries primarily under long-term leases."

As of Sept. 30, 2009, the weighted average remaining lease term for the buildings was 7.5 years.
