While I don’t disagree about the sillyness of a change in address in value, it is the reality. Up here Atherton is right next to East Palo Alto. That, of course, is much more of an extreme than say Escondido/RSF. But if they pushed the EPA border a few blocks to the west, those Former Atherton neighborhoods would see at least a 50% drop in values. Yes, your address does have an impact on the value of your home. One one street in Los Altos, the homes accross the street are Mountain View addresses and 40%/sf cheaper than those on the Los Altos side, and both are in the LA school district.
I also agree that the school issue is much more important as that also can impact home values. Parts of Mountain View up here are in the Los Altos school district and that results in higher home values for sure.
And as a buyer, yes buying in Escondido is very different to me than buying in RSF, but yes the school issues is even more important.
