Marion,
i am not familiar with foreclosure process, so i do not what will happen to you as tenant after the house goes on auction. All i see is you have a contract, you did not paid (wrongly advised, which can happen) but you spend they money, and this is what I have issues understanding.
About 2 years ago i had to stay a couple of weeks in a hotel in NY, after 2 months the charges of about $1200 were not charged in the credit card. This was a lot of money for me as it was an emergency trip. Anyway, I called the hotel so they would charge (they said they have it as paid in their system), then I called my credit card company and they said that they have not received the charge request for the hotel so they will not charge me. Well, 13 months later, i got the charge in my credit card. it was a suprised but you know what? i did stayed in the hotel and it was my responsibility. I paid it. that simple.
as i have seen other people on this board, when they found out the house they rent were in foreclosure they put the money in an escrow account. They PAID.
but anyway, it is what it is, you already did not pay and you already spend the money, now what? that is what you should be looking.
I would recommend you to move but i would also recommend you to consider how to pay what you owe, the latter as matter of principle.
