I am in the process of registering my flat in Kolkata Rajarhaat Area. I got a lawyer to access the present market value from the registrar's office with correct details. Parallely I made an assessment on my own using the same details from this website of Directorate of Registration & Stamp Revenue http://www.wbregistration.gov.in/%28S%283fxa4uvhutsjkgeognmsib4g%29%29/mv_aprt.aspx. The one assessed by lawyer is more than what is showing the above website. I am confused.Can some one please suggest which one is correct.
