The current housing foreclosure crisis is a pattern that has the potential to form a new geography. Current home foreclosures are not randomly scattered across a metropolitan area nor do they occur solely in neighborhoods that are already crime-prone and depressed.

Sometimes, squatters begin living in the houses and, in a few cases, homes have turned into drug farms. A real estate agent in Elk Grove, California, described the momentum of the crisis as “…descending into a feeling of chaos.”
