I'm not saying you're wrong but I'm curious what you have to back that statement up. Detroit is rapidly losing population[0] with no end in sight. Typically for prices to rise, there has to be some kind of demand. I guess you could just gut the supply by wholesale tearing everything down and seeing if you can sell what's left.
