FMV of immvoable property

you can get the value of the property through registered valuer

as per sec 49(1) if any property is t/f (sold) nd the person selling the property acquire it by way of will or inheretance the cost of acquisition will be of the previous owner
but here property is acquire in 1950 by previous owner hence fmv of property on the date 1.4.2001 shall be taken as cost of sich property subject to indexation.
fmv of the propety data on 1.4.2001 should be taken from registered valuer .

indexation will be done as per base year 2001 or 1980 as the property was sold in 2016
and 2001 is applicable from which year

the rule is coa*indexation of 2016/indexation of 2001
hence base me 2001 ka indexation liya jayega
however indeaxtion of 1980 is not relevent now...but aap base me 1980 ka le ya 2001 ka dono ka indexaion 100 hi h...so crux is 2001 ki fmv nd base me indexation 2001 ka ie 100 will be taken
