Landlords right to collect rent during a short sell
I am renting my condo in San Diego, California. My tenant does not want to pay rent because of the short sell of my condo. She is in a one year lease that is up November 1st. She is upset with me because I stated that I would have a washer and dryer replaced by December 1st, and I have not been able to provided her with one. Upon trying to have one delivered a month ago, it ended up being back ordered which I cancelled due to me deciding to sell the property. She believes that she is entitled to give me a 60 days noticed to vacate, have her deposit refunded, and not pay the rent for the 60 days. She believes this is fair to cover her laundry bills and having to possible move out early when the property sells. On top of this, she has only paid rent on time once. Her 60 days notice was in an email and I have asked her to provide it to me with her signature. I have not heard from her nor received the signed 60 day notice.
Please provide me what my legal rights are if any.
