Calculation of property taxes are different across jurisdictions, you are talking like your rules apply to every system in the world.

I believe in the poster's jurisdiction, property taxes are based on a percentage of the property value and are independent of the city's actual budget.

That value is usually calculated from last sale plus no more than some small percentage each year. I.e. if home 'went up in value' but didn't sell tax doesn't change much.
