I am in california. I am on a month to month.
Sadly to say, in CA, that 60-day timeline is accurate. It's actually more generous then it has to be - if you're not on an active lease, they can require you to leave in 30 days.
I just went through a similar situation, and though my landlords avoided foreclosure, it was a close thing; and there's little you can do to stop it, especially if you're not currently on a lease. I would advise looking for a new house immediately.
