If you have missed a certain number of mortgage payments, the bank will issue you a Notice of Default on your home. You then have approximately 90 days from the date of Notice of Default until the bank issues you an Auction Date for your property.
The notice of Auction Date comes from the bank 3 weeks before they are selling your property. Once your property is sold by the bank, you have 72 hours to leave the property.
When you receive a Notice of Default, you have options available to postpone your auction date and prevent foreclosure. You should talk to a reliable tax and bankruptcy professional who will explain t o you the various legal and credit ramifications that you face.
You may want to talk to a professional loan modification expert to identify your options and see if you qualify for a loan modification.
If it makes sense to list your house as a short sale, choose an ethical, knowledgeable, and experienced profession such as Marilyn Dashe and the Short Sale team at Century 21 Sea Coast in Encinitas to help you. They can explain the short sale option to you and let you know how they can postpone your auctions date with very little inconvenience to you.
