It’s worth reading rcpt’s links in a sibling comment, but this analysis ignores a) geographic distributions within California of Prop 13 effects, b) the differences in demographics and population growth between those states, c) in California, properties other than single-family homes, and d) differing rates of renting and homeownership.

I don’t want to imply that you are being intentionally withholding of data, as I don’t believe that — what I’m saying is that this type of analysis is quite hard to do correctly, accounting for all the factors in play!
