We have a number of condo complexes that started, built a few dozen units, set up pads to build dozens more, and then disappeared... Complex number one:
Complex number two... This is the one that showed me how bad things were. They were building this complex, sold one unit, build two dozen, and then went out of business.
This one comes with a story. The local fire department thought it would be a great idea to stage an exercise at this complex, thinking it was empty. One unit did sell, and is being rented out a family. Fire department came rushing in like it was a real fire, scared the piss out of the family there.
