I have a tenant who is vacating in 2months time. The problem is all the blinds in the house are damaged, grass is knee high, there are people not listed as tenants living there, they refused entry to a real estate agent for a market appraisal and the dont answer any calls I give them or hang up when I call them. Should I issue them a breach of duty eventhough they are vacating anyway? I am worried if I do they will do further damage to the property. I really dont know the best course of action as I self manage. Advice needed pls.
