I had one account with BOA for 28K, that they reported as a charge off. Then BOA OFFERED me a settlement for 6K. My credit report has since been cleared by all bureaus.
Chase wrote off the 3 accounts I had with them as part of a global settlement; I still had to pay taxes on the settled amount.
Target was the first account I settled. I made an offer to settle the account for 30%, but I'm sure I could have settled for 20-25% (maybe even less). I think credit card companies were told by the government to settle offers that were reasonable and made in good faith.
Not sure on that last statement, but make sure that if you receive an offer to settle an account for (x), that you get that offer in writing and that after you've made payment, make sure the credit card company will make sure that your credit report reflects "PAID AS AGREED" :"settlement reached" "account settled and vendor agrees that it is PAID IN FULL"
When you receive a confirmation of payment letter, make sure that it is signed (not just an electronic signature) but SIGNED by a real human person. It should also be signed by an official at the attorney's office (who has the power to make the offer) . Then you can get on to the part where you improve your credit. Send any information, certified mail. so you know that it was received and when. There is a time limit, I think 30 days, for adjusting your credit report.
