Selling property and tenant wants to break lease

[Erin Anthony]

Hi,
I am currently in the process of selling my rental unit in CA. I have a buyer and we are expecting to close escrow at the end of October. Fortunately, my current tenants lease expires October 31st. We really lucked out with the timing. Yesterday, she contacted me to request to break her lease a month early (move out Sept 30th). In the past when we had a tenant break a lease it hasn't been a problem. They helped to find a new tenant and the property didn't go un-rented for even a day. Of course it doesn't make sense to do that this time. My initial response was to just tell her no. She can move out whenever she wants, but she owns me rent until Oct 30th. Is there something I'm not considering or is this the proper response?

Many thanks!!!

Erin
