Keep in mind that property taxes are only soft linked to property value. If everyone's property doubles in value, and the city needs X revenue to run, it is still divided by the relative value of everyone's property. The only time increased property value causes taxes to go up is if there is a lot of other property that doesn't go up in value (or taxable value), which is what you have with Prop 13. Also, if one area becomes more affluent than another one (increasing its value), then they will pay more taxes.
