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!

Actually you can go to NYC.gov and go to the financing section of the site and click on property taxes. The actual tax bill and exact amount is listed, just have the address or block or lot and it will come up and it will let you know if the bill is current and the billing schedule.
