Losing business because your relationship soured is not the fault of your landlord. You can take your ex to small claims, but I don't see you have even the slightest chance of winning.As i am searching the internet i am seeing that my defenses are slim to none.
I did thought lose business:
She was under a 6 month contract with me at my gym, obligated to payments of $288 a month. On September 7th her payment was declined and so were all subsequent payments. I asked her to remove herself and all of her property from my apartment on the morning of July 28th before leaving for work, she did not. She then changed the locks to my apartment which resulted in further conversation with her which went bank and forth for 2 months. During this time i was feeling uneasy about her having access to my home whenever she wanted. Things turned up missing and found in her possession to include an old phone where i would reach out to past clients (a great source for return business) with her reasoning being that she thought she would discover who i left her for - the phone was off, it was literally a source for contacts. My stress lied in that she could enter into my apartment whenever she pleased and did so on numerous occasions. This caused a drop in my production as i made more frequent stops home to protect my property. I admit things were hot and cold and there was back and forth but i feel the changing of keys was a violation of privacy. I have been a perfect tenant my entire life and have lived at this property for 2 years and 5 months before first being late on rent directly following these events. It all really affected my peace of mind
