Taxes are a function of municipal costs and the value of all properties. If they all go up equally in value and costs remain constant then your taxes should not increase
For example, in my city, 70% of households rent and half of those are in the hood. Bad neighborhood valuations are essentially a factor of Section 8 prevailing rent, and many properties fall off (as they stop meeting HUD standards) and get abandoned as they decay, because slumlords.
The effect is that in a good neighborhood, your pro rata share of the levy always climbs, even without an increase in value.
