It’s been a busy run for metro region retail centers over the past six weeks or so. First, Gramor Development sold its Progress Ridge TownSquare for $101 million last month, then its Timberland Town Center last week for $43 million.

Now, Westlake Realty Group Inc. has sold the 296,000-square-foot Gresham Station Shopping Center to the Ohio-based real estate investment trust DDR Corp. The reported sale price was $87 million.
