Here are some other tips to boost your credit score:
Lowering the amount of open accounts you have listed on your credit report will help to raise your credit score. If you are making payments on multiple student loans, a student loan consolidation can take all those open accounts and turn them into one which will boost your credit score.
The lower your payments are, the better it is for your credit score. If you have multiple loans, the minimum payments will be higher when combined than if you were showing just one student loan consolidation payment with a smaller monthly payment.
Having many lines of credit that are low amounts and maxed out will negatively affect your credit score. It is called the debt to credit ratio. They take the amount of credit you have used and compare it to the amount of credit your creditors have trusted you with. The bigger margin of difference, the higher your credit score will be. By lowering the amount of open accounts you have that are borrowed to the limit, You will be raising your credit score. This can be accomplished by getting a student loan consolidation to eliminate the need for so many open accounts.
