A pair of Malden mixed-use buildings in one of the city’s two opportunity zones have sold for nearly $12 million.

Boston-based affiliates of Quaker Lane Capital bought 15-23 Pleasant St., 11 Dartmouth St., and 17 Dartmouth St. from New York City real estate investor North River Co. for $11.85 million.

The three parcels host fully-leased, multi-tenanted office and retail buildings in the city’s downtown. With a busy restaurant scene, direct Orange Line access and a growing “gaming district,” office developers and tenants are beginning to eye the neighborhood for transit-oriented new construction.

Steve Nohrden of Burgess Properties Inc. was the sole broker in these transactions.
