Housing's Next Leg Down

I realize everyone is glued to the stock ticker today, watching their personal net worth fall yet again; I know this because every time I wired up to do a live shot on CNBC today, my "hit" was "killed" at the last minute because the Dow dropped again. But it is precisely on days like this that we have to focus on how it all affects housing; stocks may fill our 401K's, but our homes are (or were) our single greatest investment.
