This tenant rented from me for 7 years. She was not a hoarder when she moved in. The first five years everything was fine. She was a "cat lady" and the house smelled like a litter box, but she was still not a hoarder. Apparently sometime in the last 2 years of her tenancy she lost it.
Every time we arranged to make an inspection she would cancel at the last minute with a different excuse, "I’m sick", "I didn’t have time to clean up", "It’s not a good time can we reschedule?" etc. Since she paid rent on time every month and never submitted any maintenance requests, inspecting her house was not an urgent priority. Now we know why she was putting us off!
