I would call the person who sent you the notice. They usually have a firm representing the Lender. Also, an agent may come by and offer you Cash for Keys which means they want to get you out of there with minor damage to the residence. However, these have very short fuses. I would begin shopping in earnest for a new place to live. I'd sue your ex-lanlord for any security deposit. Good luck suing a large lender!! But you DO GET 60 days if you are a tenant in place. I'd make sure I get them a copy of your rental agreement. If you don't have one you are on shaky ground.
Your plight is the plight of thousands of renter who are NOT notified by a landlord who has NOT been making payments on their rentals for months while still charging you rent. They not only fail their obligation to the lender but to you the tenant.
