I live in the rust belt. No one is buying those 30k homes. Why? They're unmaintained, falling apart, need completely rewired, completely new plumbing. The housing stock in the rust belt is OLD. This is what makes prices "so cheap" to you lot looking in from the coasts.

But the reality is no one is buying the discount properties that need major work. They're in run down neighborhoods with vacancies everywhere and sit on the market for months. They're almost unsellable - many are held onto with the hope that a neighborhood will get gentrified. Cities like Detroit and Cleveland see Pittsburgh's resurgence and think that will happen there. But for every expensive Pittsburgh neighborhood there's a Clairton and McKeesport.
