I see you are giving her a 30 day notice, which is the correct way to proceed. As some others have mentioned, next time obtain a rental agreement, and get copies of your renter's driver's license and his or her last two pay stubs. I would also run a credit report if you can. If you rent through Westside Rentals, they prescreen all of their renters for you. I feel for you. Wish you the best of luck.
