I got off the phone with the servicer of my current student loans--ACS (American education services) I asked her where I could send a Goodwill letter to remove lates from my loans--she said that ACS has something called a "Courtesy Credit Clear" The creditor grants to the borrower one time on the life of the loan to remove late payment(s). The process takes up to 60 days. She says that ACS is not the only student loan lender who does this. (I don't know if Sallie Mae does it.) But there could be hope for getting something removed.
I used tuscani's GW letter as a base format and then tweaked it to best suit the nature
of my situation. So to some student loan companies GW letter = "Courtesy Credit Clear" letter.
Maybe there is hope in erasing the past after all!
