I saw the show. Detroit was tearing down close to 4000 houses a year since shortly after Kwame took over as Mayor. It costs about $4,000 to tear down and correctly clean up a vacant house site, In Detroit there are so many housing units going vacant the city has no hope of keeping up.

Detroit lost almost 300,000 people in the last 10 years, If you figure 2.5 people per housing unit, That's around 12,000 units a year that need to be demolished. At $4000 per demo It's going to cost you $48Million a year to keep up.
