If sprawl is ending, why are there thousands of [[expensive) homes under construction on the periphery, while, simulatenously, thousands of homes are being abandoned in the core?

I don't mean back before the economic collapse. I mean, right this minute. $400,000 homes being snapped up in Oakland Township, Lyon Township, and other fringe areas.

It may be that light rail/BRT will reverse or [[at a minimum) slow down this trend. We'll see. It would be a hell of a turnaround if it ever happened, and would be a national story with huge implications.
