HRA exemption

Hi, I have recently joined a company in Hyderabad. I was residing until now and have taken a rented accommodation in Mumbai. Although my spouse and child have shifted along with me, my mother and sister are still residing in Mumbai where I am paying rent. Is it possible for me to claim HRA exemption on the rent that I am paying in Mumbai and thus get a qualification of 50% of basic (as Mumbai is a Metro). I am currently staying with my relative in Hyderabad. It can be considered as a self-occupied property as my mother and sister are still residing there.
