SPECIAL NOTE: Many people are attracted to credit lines because of their low interest rates. Rates on an unsecured credit line can be as low as 3 or 4 points over the prime rate. However, credit line interest rates can be substantially increased by the branch. If, for example, you were slow repaying your monthly credit obligation for 2 or 3 months (because of unforeseen difficult circumstances), your credit line interest rate could be more than DOUBLED!
