I am currently 90 days behind with BofA. Some history, in Oct-09 I tried to do a debt management plan through a CCCS and while USBank and Citicards were willing to reduce interest rate to 0% and 1.9% respectively, BofA would not even reduce the percentage at all. So considering my options, loss of income, medical bills, etc, I decided to stop paying with BofA in the hope of settlement.
My hope was to be in it for the long haul. Most threads reflect that the best settlement is right before charge-off, somewhere around 180 days. And at about 25%.
