Chiron Real Estate (XRN) said late Monday it has completed the acquisition of The Landing and The Riviera, two senior living communities in the Washington metropolitan area, from affiliates of Silverstone Senior Living for $249 million.

The properties comprise 292 homes, featuring a mix of independent living, assisted living, and memory care units that will now operate as a unified campus, the company said.

Chiron said it has partnered with an affiliate of Greystone Communities to continue running the properties under a seniors housing operating structure, while Silverstone will retain an oversight role under a separate consulting agreement to ensure operational efficiency.
