A Short Sale Affidavit of Seller is a document that a seller of a property must sign in order to confirm that the sale of the property is a short sale. The affidavit must be signed by the seller to attest to the fact that the sale price of the property is less than the outstanding debt on the property. It also confirms that the seller has no other assets or resources to pay the debt. There are three different types of Short Sale Affidavit of Seller: 1. Short Sale Affidavit of Seller for Bankruptcy: This affidavit is used when the seller has filed for bankruptcy and is selling the property to settle the debt. 2. Short Sale Affidavit of Seller for Financial Hardship: This affidavit is used when the seller is selling the property due to financial hardship. 3. Short Sale Affidavit of Seller for Tax Purposes: This affidavit is used when the seller is selling the property for tax purposes.
