I have a house of which, the ground floor was constructed in the year 1986 and then the first floor was constructed in the year 2000. However, I don't have the papers which state the Cost Price of the construction. Now I wish to sell the house and I am not sure how to calculate the cost price of the house for taxation purpose. Considering the fact that: Selling Price - Cost Price = Profit (on which I need to pay tax to the govt)
Where and how can I get the Cost price of my house, which the IT Dept. will consider authentic for tax calculation?
