Should I open a credit card when I turn 18 just to start a credit score?
Assuming I only use it to buy things I can afford (which I trust   myself to do), essentially treating it as a debit card, is this a good   idea? This is definitely a good idea. From my own experience, before I got my first credit card through my local bank (age 18), I tired to apply for a card that has cash back rewards and was rejected because I didn't have any credit history. After I had the card from my bank for 6 months, I applied for this Capital One card that I've had ever since.
