Vanke, one of China’s largest homebuilders, and local partner Align Real Estate have purchased two South of Market office buildings in San Francisco.

The buildings at 657 Mission St. and 667 Mission St., which total about 130,000 square feet, traded last month, according to property records. Nanrob Properties sold 667 Mission St., and 657 Mission St Building Partners sold 657 Mission. The buildings are adjacent to the SFMOMA and near the St. Regis hotel and condo tower.

According to a source with access to the deeds, 657 Mission sold for $42.6 million and 667 Mission sold for $21.9 million.

Square Mile Capital Management LLC provided a $70 million mortgage for the deal. The company funds acquisitions and renovations of creative Class A office space. The buildings combined are currently 65 percent occupied with short-term leases, providing a value-add opportunity, according to Square Mile Capital.

Another source with knowledge of the deal said the project could be renovated to become co-working space.

The acquisition is the third San Francisco deal for Vanke, which previously partnered with Tishman Speyer on San Francisco’s largest condo project, the 656-unit Lumina. Align Real Estate’s executives previously worked at Tishman Speyer. Vanke also recently partnered with Prado Group on 2240 Market St.

Vanke’s U.S. division is based in New York, where it owns multiple towers, and it also has some staff in San Francisco. Kai-Yan Lee, Vanke’s U.S. head, told the Business Times in 2015 that the firm would always have local development partners as it seeks more projects in the U.S. “We fully understand and appreciate that real estate is a local experience,” he said.

Brokers Brad Zampa, Michael Walker and Megan Woodring of CBRE arranged the financing from Square Mile Capital Management LLC.

CBRE’s Mark Geisreiter, Russell Ingrum, Tyler Meyerdirk and Matt Kroger sold the buildings. Geisreiter and Alexis Walsh of CBRE have also been hired by Vanke and Align to lease the building.
