If your house was placed into an auction, then the foreclosure process has already happened and the bank owns your home. You need to give your lender a call to discuss the current status.
You will receive an official notice of the foreclosure and notice of eviction. You may also be offered relocation assistance to leave the property sooner and in good condition.
In any event, it will not be a surprise and you will have time to organize your relocation, but start the search now.
