Stay in contact with your Landlord and the Lender. Contact the lender to let them know you have been renting the property and ask them what options you have. They may be willing to help you purchase if you so choose.
Ask for the "Auction Date" if scheduled. If you are in Michigan, there is a 6 month redemption period, during which time you can stay in the property. At the end of the redemption period, the Lender may allow you to rent from them until it is sold as Bank owned property.
If you want more help contact me anytime.
