I did. But using your link, at Travis county (2.2267), once again, it'd need to 3.6% to be equivalent levels of absolute tax paid as SF. It's effectively 2.22

I did. But using your link, at Travis county (2.2267), once again, it'd need to 3.6% to be equivalent levels of absolute tax paid as SF. It's effectively 2.2267/3.6 (62%). It doesn't matter really how you slice this, because it's not subtle. People in Austin pay way less property tax than people in SF on equivalent housing, even before other taxes (only in SF) are taken into account.
