Claiming deduction of hra and int pricipal in housing loan when owned property is in same city

Yes. You can get benefit as above stated in your queries.

Ensure that you does not stay in the same property.

1.condition: U/s 10(13A) an employee who is in RECEIPT of HRA, can claim exemption, if he does not live in HIS OWN HOUSE, AND pays RENT in excess of 10 % of his salary.

2. For Interest on Housing Loan for Let out property, You should have offered and declared the Rental receipts and claim actual interest paid on LO property subject to certian condition as specifed in section 23 and 24 and  Repayment of Housing Loan U/s80C subject to conditions mentioned therein.

But is this logical & practical,

a person is not living in his own house, rather living in a rented house in same city?

Agreed with Ajit Bhati..Only for claiming self occupied property if u do not stay in ur own property due to the fact that ur place of work is far from ur owned property & u stay in a rented premises as well u didn't rented ur owned property. But if ur property is let out then u have to show it u/h "house property" whatever may be the reason for not staying in ur owned property as benefit of self occupation will be lost.
