A good rule of thumb is 1.25% of your purchase price. But if you are in a Mello Roos area that can make total taxes much higer.

If you are in Riverside county you can go to http://www.riversidetaxinfo.com/riverside_onlineinfo.asp
click on the link stated "continue to online payment" a new window will open, click on "start search" then type in the property address... example 12345 Valley (do not put lane, street, etc) click "submit"
Then you will see some info click on "view tax info". This will show not only the taxes but also the assessment fees. Of course these might change. What you are looking at is the current taxes at the price the house was sold for....

get the total amount of the home so $156, 000 x 1.10 % = $1716
