FICO reads the CO and Date reported......every update will keep scores low.....all COs paid & unpaid in the eyes of FICO are scored the same.
By paying it will look better on a manual pull but will not raise your score!!!
If this is NOT being reported by a CA along with the OC.......paying should keep a CA from being assign or the account sold.
You can try a PFD to the OC BUT most CC COs are not accepted.
What is the DOFD/DOLA and your SOL on this debt?
