We had 4 student loans that we missed serveral payments in a row back in 2012/2013. The first time we were late was 9/2012 and the last was 3/2013. We have paid on time since then, the loans were sold and we have continued making on time payments to the new creditor. When can we expect these to fall off our credit report? I was thinking March 2020, but I am unsure because we started making payment again? Thanks!
