Another important thing about property taxes is to know when an updated assessed value is triggered and if there are any limits on how it changes. For example in SF, the assessed value is basically set to the sale price, immediately. But then the assessed value doesn't change until there's another property sale (or permitted improvements are made).
In some states assessed values are updated every year regardless of sales or improvements. [2]

Putting taxes on sales and property means that even those paid under the table can't escape taxation.
How this shapes the valuation of other things, like houses, is an interesting second order effect. Property tax rates shape how affordable housing is during the mortgage period and after.
