Whichever county the home is in, go to that website and look up the tax bills with the tax department. They are guaranteed to have accurate and updated information.
You can go to the web site http://www.PropertyShark.com and input the address to find out the taxes. You have to register with the site but it is free and worth it because you get lots of good public information on properties in Brooklyn there. If you need further assistance, contact me direct. Good luck!
