One of my tenants admits to doing drugs in the apartment, and states that he has no problem with it. He agrees to pay for a broken window and carpet replacement due to wax burn marks on the carpet. Should I evict him immediately, or should I wait for payment? His lease expires in June, and since I inherited him from the previous owner, there is no clause about drug usage I the apartments. What legal grounds do I have? Thank you so much for any advice!
