The unintended consequences of demolishing homes would be fun to watch though! (Of course, I mean in a purely ghoulish way!)
Can you imagine if rather than sell at a loss they tore them down and basically said up yours to everyone!? They would still owe money to someone for all the money they used to build them but now would only have land to sell for cash. But, of course, real estate only goes up, so no need to be so drastic. Ha.
