I have a question about the usefulness of "piggybacking", how easy it is to do, and what risks are involved. My husband has an 803 FICO score, and a card with $0 balance and a $4K limit that he uses (and pays off) monthly. His FICO would be higher, since he's Mr. Pay In Full And On Time, but he's only had a credit history since 2004. My FICO is 670 (and slowly climbing). I have the longer credit history (20 years), but some outstanding debt, and four late payments that I am waiting to see drop off of my history. At the beginning of this year, my FICO was 646. Is is worth it for him to add me as a co-owner of his credit card? How much can I expect that to help me? Is there any chance at all that it will hurt his FICO score? If it would reduce his by even a point, I don't want to do it, but if it can only help me, it would be worth our while, since we want to buy a house next year and want to get the best interest rate possible. Thanks!
