ghardy, this is a common FICO misconception, so dont be confused. FICO does not consider total debt, current income, debt-to-income, etc in its scoring. It is simply a debt risk repayment analysis, and not a financial stability analysis, period.
Simply file a dispute with the CRA on their reporting of this account as a revolving. They must investigate. If you want to speed up the process, contact BOA and tell them that they are apparently reporting it incorrectly, but make sure you file a dispute with the CRAs, for that is the dispute procedure prescribed under the FCRA.
