Assalamo Alaikum!
After all that, I got the answers of all my questions concerning the Property Tax, how to evaluate residential / commercial property, different rates for different area according to the category of the area. For all my brothers on this website, if you want any information about property tax, please visit: http://www.punjab.gov.pk/ then click /government departments/ then click /Excise and Taxation / then you can find the information by clicking on /property tax/ on the left.
