Wallace Property Co. has purchased 12 residential units in Roxbury.

In two separate transactions, Wallace Property acquired 182-184 Walnut Ave., a six-family brick house, for $750,000, and 50-52 Townsend St., a six-family property, for $645,000.

"We plan to fully renovate all 12 units," Robert Wallace, president of Wallace Property, said in a statement. "This acquisition is consistent with our strategy of acquiring underperforming multifamily properties and turning them around through improved management and making capital improvements."

Wallace said that Wallace Property plans to continue acquiring multifamily assets in Boston and in the Roxbury sub-market.
