Look at you CR TU and EX for something like *will remain on CR until month/year*
This is the date that it will drop off and will be at least 7 years from DOFD
Also If you disputed with the CRAs send them the OC letter CMRRR they must answer it after they verify with CRAs........you can look at the record & get the DOFD DOLA
What is your state SOL?
When past SOL you have more power.
