I need some additional information in order to accurately respond to your question. Was the “excessive credit use – meaning they owe more than the allowable threshold of 75%” one of the four key factors that affected the credit score? If so, it must be listed. ..in Part II of the form.
Additionally, if it is the sole reason for denial it must be listed in Part I (ECOA). None of the options on the model form match “excessive credit use”, so I believe you’d select “other” and write it in the blank.
If the excessive use of credit – 75% allow threshold is not information you received as a key factor from the CRA, as we have assumed, please let us know what the threshold is.
