If you're looking at the East Bay you're too late. Castro Valley and San Leandro were marginally affordable about 4 years ago. Now, you are probably going to need a salary of over $200K to support buying there. Dublin and Pleasanton have good schools so you'll need more $$$ out there. Livermore is probably still affordable to a mere mortal but I'd start looking further out towards Tracy or Stockton at this point.
