Housing Loan Repayment

In my opinion he can claim deduction if and only if the income from that house property is taxable in the hands of the assessee. or it should be self occupied property of the assessee. If it is not a self occupied property, the income from that HP should be assessed as his income.

If all these conditions are satisfied he can claim as deduction...

Dear K.K.

I am not sure but I think the question to be answered first in this situation will be who has inherited this property?

Is it assessee or his wife? 

I am not sure, but housing loan repayment can be claimed only by the individual in whose name the loan is taken..

in case of interest repayment the loan and house should be in the name of same individual.

In the given case if the will is towards the assessee from mother in law , then the he can claim or else its not possible.

mother in law does not come under definition of relative u/s 80C so No deduction .rest experts will tell
