Co-signing that loan could mean a dip in your credit score
My FICO score is 812. It was 828 in 2013, but I think it dropped when I co-signed a SallieMae student loan for my grandson. Payments for this loan are being made on a timely basis, always before the due date, never missed and never late. I have several credit cards, all with zero balances. When I do use any of these credit cards, I pay the entire balance due each month. Some of these cards have very high credit lines. My question: if I contact the credit companies and ask to have the credit limit lowered, would my FICO score go back up?
