There may be fees charged for the balance transfer.
Considerations like annual percentage rates, fees, rewards such as airline miles or cash back and balance transfer promotions--the process can leave your mind swimming in a sea of chaotic thoughts.
What may appear to be a perfect balance transfer offer may instead simply be an introductory offer that graduates into a higher interest than you were paying prior to the transfer.
This means that you should limit your use of balance transfers and not get into the habit of frantically searching for a low interest rate balance transfer every time an introductory rate is about to expire.
A balance transfer can be a great financial tool, but should not be considered a perpetual solution.
