Jackie--
Think about this from the lender's perspective. Would lending to someone with a poor deposit account record at your bank give you warm fuzzy feelings about the potential for repayment?
Is the credit report full of good credit history, or is it just devoid of negatives?
If the applicant has no credit history and a poor deposit account record, that could be enough in the mind of a conservative lender to deny an application.
On the other hand, if there is something else lurking in the lender's gray matter that resulted in the turndown, perhaps the AA notice needs some work.
Happy holidays!
