Condo towers in Miami that were being put up and finished as the crash arrived, were often entirely empty and couldn't find any buyers. You could buy cheaper units for $30k to $50k. It was common to see 50%-70% haircuts, drops from $180k to $90k etc. Over six years (2003-2009), Miami added 23,000 condo units for a city of 400k. In Dec 2008, nearly half of those remained unsold.

Las Vegas saw some similar action. It suffered the worst overall top to bottom crash of any major city in the US.
