Income tax benefit on maintenance on the self occupied flat

Hi, I have one rented flat on which I am paying income tax as per the calculation. I have another flat in which I am residing with my family. Both of my flats are loan free. I am not availing any tax benefit on the occupied property, my question is, is it possible to claim the benefit on the maintenance of the self occupied property, anyways i am spending on the maintenance of the flat. I am also not availing any tax benefit on rent for me since I am residing in my own flat. Please advise.
