True, some individual homes fell more than 50%, but in aggregate (per Case Shiller) they fell by less than that — about 42% or so overall.
But, my point was more that you can’t expect or plan on something like that… that decline was the result of a giant bubble with epic overvaluation, nothing like what we are seeing now. And even then, the typical house didn’t drop by 50% — why would you expect that to happen now, when the valuation level is substantially more tame?
