If you are in foreclosure and the sale date is scheduled in 27 days then no one will know for certain who the new owner will be until the auction has concluded itself. The bank may be taking the property back if no one bids on it or a private party may bid on the home and become the new owner.
So for you to ask the lender now for cash for keys is premature. You want to wait until you are approached by the new owner regarding the outcome of the sale and what their expectations are in regards to your vacating the home. At that point you may strike a deal to agree to vacate on a certain date in exchange for cash for keys. But until then, no. Just wait.
Hope that helps!
