Christie’s International Real Estate Launches Charleston Affiliate

Two South Carolina-based Christie’s International Real Estate affiliates are teaming up to form a joint venture and launch the brand’s first Charleston, S.C.-based operation. The firm announced the launch of IndigoOak Christie’s International Real Estate on Thursday. 

The new affiliate is the result of a joint venture between The Litchfield Company, based in Pawleys Island, and the Greenville-based Blackstream International. 

IndigoOak will be led by co-presidents Michael Mumma and Will Davis, who will also serve as the broker-in-charge. Mumma is the CEO of Blackstream International, while Davis is the CEO and president of The Litchfield Company.

In 2024, Davis’s firm, The Litchfield Company closed 850 transaction sides for a total of $421.37 million in sales volume according to RealTrends Verified data. This earned the brokerage the No. 765 ranking nationwide for sales volume in the 2025 RealTrends Verified Brokerage Rankings. 

“Will, Michael and their team bring deep local knowledge, proven operational excellence, and a shared commitment to client service to our new Charleston affiliate,” Gavin Swartzman, the president of Christie’s International Real Estate, said in a statement. “Their collaboration reflects the entrepreneurial spirit that defines our affiliates and continues to fuel Christie’s International Real Estate’s growth worldwide.”

The company said this new affiliate builds Christie’s International Real Estate’s presence in South Carolina’s luxury space, adding to its existing operations on Hilton Head Island, Pawley’s Island, Myrtle Beach, Georgetown County, Orangeburg, Manning and Greenville.

“With so much movement in the Charleston luxury market, buyers and sellers are looking for a name they can trust, and Christie’s International Real Estate provides that,” Davis said in a statement. “Having been affiliated with the brand for several years, Michael and I can confidently say that IndigoOak will set a new bar for real estate in the region.”
