In June 2005, I missed a payment on a credit card by 5 days. The bank raised the interest to 24%. I got a loan of 500K with low interest to pay for this credit card. However, I decided not to close the account. I have since then used been it for balance transfers because the bank was offering low APR on balance transfers. I have no other late fees on my credit report on this account but for the large balance.
Is it possible that the late payment made so many years ago and the high APR is still hurting my credit?
