Boston-based real estate firm STAG Capital Partners recently launched an anticipated $400 million fund that will focus on acquiring high-yield, single-tenant real estate properties across the United States.

STAG seeks investments from institutional limited partners for the fund.

STAG Investments V LP (STAG V) is the firm’s fifth investment fund for the acquisition of single-tenant industrial properties, the company said. Since its establishment in 2003, STAG Capital has acquired approximately 200 properties at an acquisition cost in excess of $1 billion.
