I am turning 18 and I am a Student, I need strategies on building great credit soon. Where should I start?
The details of credit score calculation tend to change periodically, but the fundamentals are mostly consistent.  Pay your bills, keep your average account age high, overpay your credit card minimums, and keep your overall debt low.  And do soft pulls on your credit report to see what's happening. First, the simplest route: pay all your bills early or on time.  Automatic deduction may be useful in this regard, especially for bills with predictable amounts.  A corollary to this tip is to never leave an unpaid bill.  What often happens to young people is in the course of moving around they leave the final bill unpaid and it gets reported to collections.  Make sure you follow up online with all bills, even after canceling the service. Second, average account age and oldest account age matter.  Open an account like a credit card and never close it, so you'll have an older account (hopefully a zero-fee card).  Try to keep other accounts open rather than closing them (no need to cancel a zero-fee credit card) so your average account age stays higher.  A card that works on internal systems (like a gift card) is not going to show up on a credit report; a card that works like any VISA/MC is likely going to show up.  The rule of thumb is if they need your SSN to run a credit check for the application, then the card will appear on a credit report.  You can pull your credit report to find out if the card is listed (you may have to allow time for lag before the card appears, but I'm not sure how long that might be).   Third, a tip for extra credit score is to pay more than the minimum required on credit card bills.  You can achieve this by either using your credit card at least once a month or by leaving a small hanging balance each month so there's always something to overpay next month.  Credit card reporting will be either: unpaid, underpaid, minimum paid, or overpaid.  Minimum payment helps your score and overpayment helps more.  If you can use your credit card every month, that will give you something to overpay every month.  Otherwise, you can leave a small debt left on the card but still pay over the monthly minimum.  However, your total debt load, especially debt carried on your cards, counts against your score; aim for less than 10% of your limit. Finally, of course, is to pull your credit report periodically.  You need to know what others are seeing.  Since debt load utilization matters, make sure the reported card maximum is correct on your credit report.  Talk to your bank or account issuer if the limit is wrong.  If a collection appears, then you need to handle it.  Often you can negotiate with the collector, but be careful to negotiate how they will report the resolution.  You want them to agree to remove any negative information (either in exchange for payment or because of a mistake).  Failing that, you want them to mark it paid in full or satisfied in full; letting them notate your score that you only partially paid is what you want to avoid, since it most signals someone with cash flow problems and credit issues.  They control their reporting to credit bureaus, so if the person on the phone demurs, ask to speak to their supervisor or someone with negotiating authority.  Try to get any agreements in writing. Remember that your total debt load is a factor in your credit score.  Home loans and student loans do affect credit score.  If you take on a smaller home loan, then it will affect your credit less harshly (and leave you with smaller monthly payments).
