There's no mystery about why so many homes in the East Bay are underwater. Prices there have fallen further than in the other regions.

Note: I don't have aggregate price indexes for the regions shown in the First American report, so I just showed the component counties.
The number of underwater homeowners continues to grow. (See this map for numbers from November, 2008.) As I mentioned in an earlier posting, the number of foreclosures is likely to continue growing as well.
