Wow, 10 days is unheard of in the Short Sale business in getting an approval from the Lien Holder.
Better yet, the Lender included in the approval letter:
“Our Customer(s) Seller(s) agrees that upon the posting of the agreed upon Short Sale amount, the remaining balance of the loan, if any, will be charged off and no additional payment will be required. Please note a $0.00 balance will appear on the Customer’s file with the credit bureau as “Account legally paid in full for less than the full balance.”
This is as good as it gets, but please note that sometimes the Credit File will also report, “Account paid in full.” Of course, sometimes it goes the other way as well, which is why you should work with an expert who knows how to delete those wrongfully reporting accounts.
