It’s hard for me to comprehend how people think that certain areas will decline more than others.
Things are all relative and desirability of one neighborhood is relative and proportionate to the other ones’.
I think that all of San Diego neighborhoods will decline about the same percentage but at different times. We are just getting started so, sure, the wealthier owners are more solvent. But as the market declines in earnest, buyers will look at relative value for the money when choosing among neighborhoods.
