"Twist" provides a story from Barron's about the tsunami of default and the shadow inventory of foreclosures:
Amherst estimates this massive overhang at seven million units. That’s the equivalent of 135% of a full year’s existing-home sales and chillingly greater than the 1.27 million units that made up the overhang in early 2005, when the housing bubble had just begun its dizzying and more than a little lunatic ascent.
Put another way, of the 56 million units that the Mortgage Bankers Association says make up the mortgage universe, Amherst gauges 6.94 million units are in what it dubs the "delinquency pipeline" eventually headed for liquidation. And it reckons that another 300,000 mortgages replenish that unwelcome flow every month.
Essentially, then, this shadow inventory represents a massive furtive supply of future foreclosure. Amherst fingers negative equity as keeping the delinquency pipeline heavily stocked. Quite a reasonable assumption, we think. A home owner, saddled with a house that’s valued at less than it cost him to buy or that he can reasonably expect to sell it for may lack the will and, more importantly, the wherewithal to keep making payments on his mortgage.
