So, back in the early Aughties, banks were handing mortgages out to anybody who could hold a pen and fog a mirror. The "NINJA" (No Income, No Job or Assets) loan became a thing. Lenders were chasing winos down alleyways and forcing them into $350k McMansions telling them they could "flip" the house for half a mil next week. I actually overheard a couple of night stock clerks at a Kroger back in Knoxville talking about the houses they were flipping, back in early '07.
