First and foremost you should do more research on credit cards and what everything means. As expressed by others the balance transfer fee is not what you think it is.
Credit cards can be great, they can also quickly erode your credit score and your standing. So understanding the basics is VERY important.
The credit card that is right for you should have the following criteria.
- Have no annual fee.
- Be accepted where you plan to use it.
- Provide the best perks for your situation.
The first two points should be straight forward, you should not have to pay a CC company for the privilege to use their card. They should pay you through perks and rewards. It should also be a CC that can be used for what you need it for. If you travel internationally a lot and the CC you choose only works within the US then what good is it?
The third point is where you need to ask yourself what you do a lot and if a CC can offer rewards through travel miles, or cash back or other bonuses based on your lifestyle.
The transfer fee is not what you think it is, people who already are carrying debt on another credit card and would like to transfer that debt to another credit card would be interested in finding a fee or a low %. People do this to get a batter rate or to get away from a bad credit card. If one charges 28% and another charges 13%, well it makes sense to transfer existing debt over to the 13% provided they don't crush you on fees.
Since you have no credit card debt (assumption based on the fact you want to build your credit), you should ask yourself for what purpose and how often do you plan to use the credit card.
Would this card be just for emergencies, and wont be used on daily purchases then a credit card that offers 3% cash back on gasoline purchases is not for you.
If you however love to travel and plan to use your credit card for a lot of purchases OR have a few large purchases (insurance, tuition etc.) then get a credit card that provides rewards like miles.
It really comes down to you and your situation.
There are numerous websites dedicated to the best credit card for any situation.
The final thing I will say is what I mentioned at the beginning, its important, CC's can be a tool to establish and improve your credit worthiness, they can also be a tool to destroy your credit worthiness, so be careful and make smart choices on what you use your card for. A credit score is like a mountain, it requires a slow and steady discipline to reach the top, but one misstep and that credit score can tumble quickly.
