After rehabbing my 18 loans, the original tradelines got closed and the balances were transferred Sallie Mae. When I consolidated those new tradlines into a Direct Loan, the old ones showed up as "Paid, Closed/Never late" under account status. I'm looking at my official Experian CR that I downloaded a few weeks ago. Be careful looking at CreditKarma and such. They way they show notations doesn't always match official CR's.
The tradelines that I originally rehabbed have since fallen off my credit report, and I don't recall what the notation was for those.
Maybe the standing of the account determines the notation upon consolidation? I'm not sure.
