I am so sorry to hear the situation you are in. This year alone I have helped two people whose buildings were sold and the new owners were asked them to vacate. I am glad to say both are living in their own homes today. You will first need to work with a mortgage lender to see what you can qualify for. My favorite is Mary Kay Laurent with Guaranteed Rate at 773-518-6859.
I only wish you situation happened in January when bank owner properties were a real deal!
