Sorry to hear about your situation, unfortunately, it is not unusual.
The first thing you need to do it call your Lender and find out about the moving date. Normally, the Sales Date is the day the bank takes ownership and you must move out by then... however, some banks are offering two options:
1/ Deed in Lieu of Foreclosure - meaning you sign over the deed "voluntarily" and negotiate a moving date
2/ Cash-for-keys - The bank will provide you with a Sum to cover moving expenses in exchange for your moving out and leaving the property in good shape.
Call them and find out if either of these options are available to you. Each bank is different and rules may be different in your area ... but call them and find out.
