CENTURY 21 Award's story could easily begin and end with the simple fact that pound for pound this Southern California based real estate brokerage lists and sells more real estate than any other Century 21® franchise in the world. In consideration of the fact that its parent company, Century 21 Real Estate LLC, is the largest, most globally recognized real estate brand*, it's no wonder homebuyers and sellers rely on this brokerage and their agents for their real estate needs.
