I know that each late drops at the 7 year anniversary. ThenI believe, if the acct wasn't a co, it looks like a good TL.
I have had many drop before. I have had entire bad accts drop early! Those were co's & I don't think they EVER would end up as good TL's. A couple others were CA's.
Each individual late with the OC drops from credit reproting, under FCRA (a)(5), at 7 years from its individual date of delinquency.
The account does not drop, only the ability of the CRA to include prior delinquencies under the OC account after 7 years.
If a derog has passed its 7 years, the CRA is prohibited from making any reprot to or reference of it.
It cannot be included in any derogatory manner in any CR after 7 years from the date of each individual delinquency.
