Should I open a credit card when I turn 18 just to start a credit score?
Yes, as long as you are responsible with the payments and treat it as a cash substitute, and not a loan. I waited until I was 21 to apply for my first credit card, which gave me a later start to my credit history. That led to an embarrassing credit rejection when I went to buy some furniture after I graduated college. You'd think $700 split into three interest-free payments wouldn't be too big of a risk, but I was rejected since my credit history was only 4 months long, even though I had zero late payments.  So I ended up paying cash for the furniture instead, but it was still a horrible feeling when the sales rep came back to me and quietly told me my credit application had been denied.
