After a quick look, all North County coastal zips (Cardiff to Carlsbad) show YOY price increases even though sales were lower and August/September were the big credit crunch months. While monthly median prices are not the end-all be-all gauge it seems odd that every single one saw increases in this environment.
Oceanside as well as that other coastal city near LaJolla, Santee, showed price declines and heavy sales declines. Seems like there is a big divergence in areas where subprime loans were the prevailing choice of purchases and re-fi’s.
