"Office market fundamentals in the Washington, DC metro area are strong with continued space demand from a diversified economy, including both the private sector and the federal government," says Dave Hardman, managing director and US head of real estate investing at Morgan Stanley. "The acquisition of this high-quality portfolio improves the office component of Prime through predictable cash flows supported by long-term credit leases and a balance of stabilized and development assets."
