Why can't the Chicago government sell the dollar hotel?

After being hit hard by the economic crisis, Chicago, which has been described as "Sin City" by many film and television dramas, has never got rid of this "notoriety". Gang violence and the proliferation of illegal guns have made murders in this city hit record highs in the past two years. Many empty buildings are either used as temporary residences by criminals or occupied as nests by wild cats. Because the "foreclosure" incident reached the highest level in American history, the vacancy rate of houses was unprecedented, and the serious housing crisis turned Chicago into an "empty city".
