This is basically a document telling you that the lender will foreclose on your property if you do not take action to stop it. Ignoring it will only lead to further legal trouble, and it could prevent you from being able to negotiate with the lender to find a solution that allows you to keep your home.
While the content of the letter will change depending on your situation, there are a few important aspects to include: Provide all details the best you can, including correct dates and dollar amounts. Explain how and when all situations were resolved. Detail why problems won't happen again.
The redemption period also runs for 3 months after a foreclosure judgment is entered, so, depending on when a judgment is entered, the redemption period can run longer than 7 months from service.
Once you are delinquent by 120 days or more, your lender can initiate foreclosure proceedings in court. Illinois is a state in which all foreclosures are judicial foreclosures, which means the court system has jurisdiction over the matter.
