This is a good map. I am still contending that desireable areas with good school districts and a substantial poipulation of homeowners with high equity stakes will not be hit as hard as other areas. I am not sure that I ever read that any posters said that any areas were immune to drops at all.
Also looking at the map, I see a high concentration of properties in UTC. I also see another small concentration at Sea Haus. I would be more then happy to analyze the locations and housing types of the other marks on the map if you like.
I am not saying homes are not going to foreclose in La Jolla, please do not get me wrong. There will be more, and it will go down. Also I heading to Mission Hills, one of the areas you mentioned in about an hour to explain to a frustrated homeowner why her little 2/1 cottage will not sell for 800 a sq ft.
I am just trying to provide a more introspective analysis of the data you provided.
