Does anyone know how long it takes to show improvement for payment history. I have managed to get my util. to 7% (great on FICO), length of credit history (Great), new accounts (great), payment history (not good). Scores have been increasing but now seem to be stuck at 680(TU) , 642(EQ), & 645(EX). I have made on time payments for the past 10 months. Will my score see a jump when the 12 month mark is past or will I need to wait 18-24 to see any more movement?
