If you already have a good-to-excellent credit score and a low debt-to-income ratio, you may want to consider refinancing your student loans. When you refinance your loans, you take out a new credit-based private student loan and use the money to pay off some or all of your current loans. (The lender will generally send the money directly to your loan servicers.)
The number of credit accounts you have open is also important to control. Credit cards are easy to get: Almost every store has a quick, convenient way to get you a new card. Attractive incentives, such as big discounts on purchases the day you sign up, add to the temptation. If you shop in that store often, it may be worth getting its card; otherwise, resist the urge.
Carefully review older debt that shows as charged-off. Before contacting the creditor or collection agency, check your state laws to see if the debt is statute-barred or time-barred, meaning that it is too old for creditors to attempt further collection. If it is not statute-barred, even contacting the creditor can re-instate the debt as currently collectible, which can drop your score.
Next, estimate your monthly spending habits for other expenses such as gas, groceries and entertainment. Create a limit, based on your income, of what you can spend in each of the different categories of expenses. For example, if you tend to spend $400 a month on groceries, try to stick to $300 a month on groceries by making changes like buying generic brands, using coupons, and resisting impulse purchases.
