With General Growth filing for bankruptcy last week, analysts and researchers are taking a fresh look at the firm. For example, Real Estate Economics took a snapshot of General Growth’s portfolio to show the top 10 markets where it owns malls. Atlanta tops the list followed closely by Dallas and Las Vegas. Perhaps the most surprising market here is Omaha, although the company’s roots in Iowa partially explain its strong presence there. Overall, the top 10 markets account for 23.4 percent of General Growth’s total square footage.
