Security deposit on newly purchased home

[Troy B.]

I just brought a 2 unit property with one existing tenant. My concern is if he moves out and I have no prior knowledge of the apartment prior to him moving in a year ago how can I legally keep any of his deposit if he moves to cover wear and tear?

He is a smoker and I know the apartment walls are very dirty because of it and will need painted. Would I have any rights to use his deposit for repainting costs?
