I would not apply for a refinance the loan unless I was sure I could get it. I think your best bet would be to join a credit union and then speak with a loan officer and show them your credit report and see if they will approve you. In this way you save a INQ on your credit report.
At 19 you are just starting out in the credit world so it may take some time to get were you want to be.
So you know where I am comming from I was so bad with my credit that I was in 70k of credit card debt and it cost me a relationship and almost my job. It took my almost 5 years to get out of debt which was in November..
Things are great now but here is the advice I would give to.
Never pay late. Never ever ever.
Except for a car loan and a home, dont buy anything with a Visa or Mastercrad unless you can pay it off in 1 to 12 months.
A store card to buy a big ticket item over a 24 or 36 month period is okay as long as it is a 0% and you have to pay before the end of the loan so you dont get all that back interest. If you dont pay even one dollar by the end of the interest free term, you owe interest on the whole amount for the entire term of the loan.
If you have medical biils you cant pay try to make arrangements to pay. That also goes for any loan.
Dont imitate people who go out and try to get lots of credit cards. A single VIsa/MC, store card and Gas card should be good enough. I have a Visa card, a Sams card, and a Gas card.
Finnaly be patient. I am almost 52 and didnt get my act together until 5 years ago when I entered a DMP program to pay my 70k of debt off. Most of the debt was buying things I didnt need or could of waited for. You dont want to learn the hard way like I did. I wish this forum was around when I was 24 and started my road down to credit hell.
Use me both as a bad example and a good one.
