The Mysterious 1555 S. Wabash Building

YoChicago is perplexed by this mysterious building and they're looking for answers:

With the possible exception of Lexington Park Condominiums, is there a new-construction condo building in the South Loop with a more mysterious present and uncertain future than 1555 Wabash?

Based on the best information available online — current listings, Redfin’s records of past and pending sales, and the Tribune’s database of Cook County sales records, all of which have their limitations – there have been no closings at the 14-story, 176-unit building at 1555 S Wabash Ave since October 2009, and only five homes have gone under contract between July 2008 and last week.
