my tenant used to be the owner of my apartment.. That means he was screened and all the criminal background checked was done and everything. Later i bought the apartment. the association said my tenant has to be re screened. I am not sure if the association recognized that the former owner is now the tenant, but i am more or less sure they know. My question is : assuming that they don't realize that the tenant is the former owner. when they realize that the tenant is the former owner, do they have a legal ground to ask for a criminal background check screening again? what is my argument in telling them that i don't have to pay for a background check for someone who is not a new tenant or occupant of the unit?
