We moved out two months earlier than our lease ends, but are still fully prepared to keep paying rent until May. We were responsible for getting the lawn mowed, so I had my dad go mow it. While he was there, he saw my landlord living there; is that legal?

Can my landlord still make us pay for the rent even though he’s living there before our lease ends? He also hasn’t said any more to us about whether or not we get our deposit back.
