A Swedish real estate company that plans to acquire $1 billion of U.S. assets closed on a pair of deals totaling $169 million Thursday to buy two recently developed South Boston apartment complexes.

Akelius Residential AB bought the 255-unit West Square apartment complex at 320 D St. from Lincoln Property Co. and the 24-unit Westside Crossing at 339 D St. from City Point Capital of Boston.

Akelius is concentrating on Boston, New York and Washington, D.C., for its U.S. acquisition pipeline, said Chad Perrone, regional vice president for Akelius’ Boston office, which opened in March.

“Our acquisition profile has always been to invest in really strong, stable markets that have a lot of growth potential,” Perrone said. “Those three markets are some of the strongest in the country.”

The price works out to approximately $606,000 per unit. Both complexes were completed in 2014 and are approximately 95 percent leased. West Square is advertising rents starting at $2,115 for studios.

Lincoln Properties acquired the West Square parcel in 2012 for $12.2 million following the bankruptcy of a previous developer, SB Housing Enhancement LLC, which had planned to build 245 condos.

Perrone said Akelius is looking to acquire more multifamily properties in Boston and inner-ring markets such as Somerville and Watertown.

“With a city like Boston, there’s a lot more opportunity right outside the urban core,” he said.

Akelius acquired 900 apartments in Manhattan and Brooklyn earlier this year. The company owns more than 50,000 multifamily units in six countries.

Boston-based Nixon Peabody served as legal counsel to Akelius on the South Boston acquisitions, with Christopher Froeb and Christina Ricotta leading the deal team.
