Passbook Loan I don't know much about this subject, but I believe a passbook loan is basically a loan where you pay to borrow your own money. You use your savings account as collateral. I have heard mixed reviews about it establishing your credit as well. As I have heard, you should ask your bank whether it has a mechanism to report incidentals or small loans.
Why don't you get an over the limit check loan it reports to the cra's and your not out any money inless your over the limit
