I gave a month's notice on my month to month rental 6 days ago. I offered to vacate earlier than a month if that would be helpful, and my landlord said he has someone in mind to rent it, and would refund me any days he rented it sooner than a month. Can I change my mind and stay? This is the 2nd time I have given notice and then changed my mind, but last time my landlord did not have a new tenant in mind.
