Capital gain. sold my house

Get cost of house from Government approved valuer as on 01.04.2001!!

For example:-

Government give the value as on 01.01.2001 is Rs. 4,00,000/- please calculate it.

It is unjustifiable. The valuer would estimate it to about 11 to 12 lakhs.

The cost index ratio of 2017-18 to 2001-02 would be approximately 2.5 to 2.8

Finally the indexed cost of the house would be almost same or higher than the sell price..............means no capital gains..........no tax.
