> The only way they could pass the extra tax onto you is if you are not market rate and there is a law that allows them to do this

Not sure what you mean by this: my landlord can raise my rent for whatever reason (or no reason), by any amount they desire.

I can choose whether or not I want to pay it, of course. But I imagine moderate increases to cover at least some (and maybe all?) of the cost of a property tax increase would be swallowed by most renters, given that moving is also a cost, and often a large one.

> If your landlord gets a property tax cut, would they pass on the savings to you? No.

In fact, we have empirical evidence for this. The campaign for Prop. 13 claimed that landlords would pass on the savings, but after it was passed, no corresponding drop in rents was observed.
