Rustico,
Just to be clear, my intent was not to rib you. You pushed me to challenge myself and my assumptions. I like that. I chose CV because many of the participants here follow that market and homes in the same class. I have a bad habit of using blanket statements and you have exposed that. Imagine the horro my wife goes through when I tell here everything is 5 minutes away when she asks.
I looked at San Carlos and have a few issues with using it. First the sample size is much smaller with only 61 actives and 28 pendings which btw is not stronger than the CV ratio. It is also a very homogenous range of homes with prices running from 400K to 700K (with prices higher being very rare). It could be a good measure for the entry level market.
When i look at CV I see an area with great schools close to the employement centers for the white collar professional workers that are so predominant around this blog. If I was addressing a different audience I would have chosen a different area.
