Just came across some really interesting regional spreadsheets available here -
Subprime and Alt-A Mortgage Conditons
First with the Alt-A's
191 NJ zipcodes have over 10% of the Alt-A houses in forclosure.
I have not figured out how to import some tables yet - but the Alt-A foreclosures are definitely hitting all of the towns. Of course numerous zip codes in Newark and Paterson, but also Alpine, Rumson, and Avelon all have over 20% of Alt-A's in foreclosure.
