I recently completed a short sale of my previous home. I had XXXX mortgages on the property. The primary mortgage was completely paid off and the second mortgage received a portion of the remaining balance. I thought the sale went through appropriately and we coordinated with the lenders to make sure they would accept the terms. After the sale everything appeared to be processed correctly ; however, I was recently notified that the second mortgage lender ( Citibank ) is suing me for the remaining balance. This is extremely upsetting because prior to the sale Citibank provided a letter stating they were accepting of the terms and waives their right to pursue deficiency judgement against me. I am now in shock and nervous about what to do. I thought we did everything per the book and now I 'm in this mess. Any help would be appreciated!
