If you have been contacted by someone from the bank or a realtor let them know you are interested in "Financial Relocation Assistance" AKA "Cash for Keys" in order to be able to move. If it's not too late they may work with you for mutual benifit.
I wish you all the best,
Sorry to hear about your situation. Not sure about real estate law and tenant rights in Wisconsin. You need legal advice. I had an army family that got representation and advocacy. Check with your county of residence. If you are looking at Round lake, thats lake County dept of housing. If you have an enforceable and legal lease you have some rights. Best of luck!
