An investment firm based in San Diego, California, paid $208.1 million for three office buildings that define much of the downtown skyline in Orlando. San Diego-based Southwest Value Partners bought the 27-story Bank of America Center, 19-story One Orlando Centre and 18-story Citrus Center, which have a combined total of one million square feet. The seller was Atlanta-based Cousins Properties, which recently sold its 20 percent interest in Courvoisier Center, a 343,000-square-foot office building in Miami’s Brickell Key area, for $33.9 million.
