That’s not the best way to increase your credit score — and I wouldn’t trust this scheme! Instead, take out a “secured card” — where you deposit an amount ranging from $500 to $2000 in a bank, and they issue you a regular Visa or MC. Your credit limit is the amount of your deposit, so they are taking no risk issuing a card to someone with a low score. Every month charge just a little bit on this card — and then pay it off ON TIME and in FULL. That will do more to raise your credit score than anything else. Here’s a link to find secured cards.
