After being issued a 3-day notice b/c one of my roommates did not pay rent for August, the landlord asked us to voluntarily move out so that he could just re-rent the apartment and not have to go through a proper eviction. We obliged and now because he was unable to rerent the unit in time, he is charging us rent for September and is refusing to issue a security deposit. He refused to give us anything in writing before we left and said he was just trying to make it easier. It has been well over the 21 day period that landlords have to issue a statement for why they are keeping a deposit and I have not received anything, even at the old address. I would like to go after him for a constructive "self-help" eviction for 3 times the deposit plus a portion of rent. Is this doable?
