BellSouth sold its interest in two major metro Atlanta office properties, but will remain as a tenant in both locations. The Atlanta-based telecommunications company sold its interest in the 28-story 1100 Peachtree Street in Midtown Atlanta, and the six-building Chastain Center office park in Kennesaw, GA, to to USAA Worldwide Insurance. Carter & Associates ONCOR Int'l, which holds the remaining interest, will retain its stake in both properties. San Antonio, TX-based USAA owns and manages more than $66 billion in assets, and has locations throughout the United States and Europe.
