Maybe I misinterpreted your original comment. Are you suggesting a that the taxes increase by 10% of the going rate (e.g. 5% -> 5.5%?), or the taxes increase by 10% of the property value (e.g. 5% -> 15%)?

If it’s the latter, then that makes more sense. That would be unsustainable for a landlord, because no way in hell can someone pull an extra 50k out of their ass each year on a 500k home.
