My tenant tried to commit suicide in my house and could have burned it down. What should I do?

At the risk of sounding heartless, I would not lease to this woman due to her mental and physical issues. Why? Could this person attempt this again? Sure or possibly burn ALL the property down with you in it. It is a matter of safety and economics. She should be in a hospital receiving the mental health care she so desparately needs. Talk to her uncle, after all, he is responsible for bringing her into your life in the first place. In a way she is lucky, there are property owners out there that may have sued for damages. Good luck.
