The Property Tax Person Cometh...
For information on your property tax bill: view and print your bill, pay online, appeal your assessed value, etc etc, visit San Francisco's Office of the Treasurer. You'll find all the information you need!
Want to estimate property tax on a listing you're interested in? 1.2% of the purchase price is a good, conservative rule of thumb. This is the annual amount, btw.
For example, on a $900,000 home, the annual property tax will be about $10,800.
