We had a previous tenant move at the end of his lease. He was an ok tenant. However, there were damages, to include that he tried to install a Nest thermostat and blew a fuse because of it. He tried reinstalled the original thermostat and wired the emergency heat to the cool terminal. Long story short, we sent him a disposition of deposit with an invoice because his deposit didn't cover all repairs. He emailed us back stating we have no authority to utilize or charge his name to anything. He had some attached legal copy right documents of his name with penalties of the use of his name. He ended the email with we should be receiving an invoice shortly and hear from his attorneys. I've heard it all, y'all..
