there is a trick here, you can say my house is far from my office and say I have given it for rent and I am residing in a rented House.
Now you can claim both HRA and Tax benefits by producing the House rent receipts of your rented house and loan interest certficate of your own House. But you have to show the rent you gets for your own house as a income from other Sources.
LAW allows somethings and you need to be smart ot use them. :)
