Bravo for the great information above!!
By definition, your credit rating is a record of how well you pay someone back the money that you owe them. The only way to establish credit is to borrow money and then pay it back as agreed.
You can do this several ways: 1) A revolving line of credit - most visible form of this is a credit card. You have a limit, and you can borrow, and pay it back, borrow again, and pay it back, and borrow again and pay it back . .. Many people start out with a secured credit card. You have to deposit an amount of money into the bank - which then issues you a card with that limit. If you do not pay as agreed, then the bank takes your money on deposit to cover your balance. A famous brand of secured credit card is the Orchard Bank Secure Master Card. Note: This is way different than a Pre-paid Visa or Mastercard. Pre-pay cards are simply stored value cards - like a gift card that can be used anywhere. With a pre-paid card, since you don't owe anyone any money - you are just using your own, there is no credit reporting. Second is a traditional credit card without any security. This card poses more risk to you if you are not fiscally responsible, because the debt can't be washed away with funds on deposit. In this case, it's my opinion that you see if your bank offers a low limit card that you can apply for. This gives you the convenience of paying your bill at the financial center (saves mailing time), and many times you can automatically have the minimum payment, or more directly taken from your checking account. Further, your bank may offer overdraft protection where if you overdraw your checking account, the funds will come off your credit card to coever and pay the item - thus saving you the overdraft fee. Please note: if a card is issued to you with a limit you don't think you can handle, you can call the number on the back of the card and ask to have it lowered.
2) A personal loan - sometimes called a signature loan. Perfectly honest, small banks and credit unions are better at issuing this type of loan than huge banks. You can go in, maybe need a co-signor, and get an loan for a certain amount, maybe $1000 - $2000. Then over the next year or two, you owe a payment back to the issuing bank each month. Here's a hint - Don't spend the money. Put it in a high yield savings account, and then make sure you make your payments on time each month. Chances are, the interest rate for this loan will be similar to a credit card interest .. upwards toward 16%. There are 5% savings accounts out there, so you are paying 11% on the money - with $1000 loan for 1 year as an example, you are paying less than $100 in interest.
If it sounds like I work in a bank . .well, actually I do. I specialize though in estate administration and intergenerational wealth transfer (when someone dies - get to give out all the money) Hope this helps to get started. After you take this step, start a thread asking people to explain how credit scoring works and I will come back and do my best there too.
