The best way to improve your score is to have good behavior reported every single month. For example, you can take out a secured credit card and use it monthly. Charge no more than 10% of the available credit limit, and pay the balance in full and on time every month. Your credit score will improve as your negative information ages and your credit report fills with positive information.
Consolidating the debt probably won’t hurt your credit scores over the long run, but there could be a short-term impact from the new loan with a balance. So I can’t guarantee that your scores won’t dip when you do this. If your scores are strong enough to get the lease now you may want to go ahead and do that. If not you may be taking something of a chance – it could go either way. Will Debt Consolidation Help or Hurt Your Credit?
Assuming you are consistently paying on time (the No. 1 thing you can do to help your credit), take a look at your debt-to-available credit ratio. You want to get that to under 30% (under 10% is even better). Your credit mix is also a factor. If you have the income to make more than minimum payments, though, that is the best way to make an impact. You can read more here:
The accounts section contains a detailed history of all accounts (open and closed), your balance, and your payment history associated with each account. You should be able to see month-by-month payment information for 7 years of history. Each month will have a symbol next to it that indicates whether the account was paid as expected or if it was late.
With poor credit, you may not be able to get approved for new credit products like credit cards. Although you may still be able to take out an auto loan or a mortgage, you’ll pay a much higher interest rate because of your low credit score. Compared to a borrower with good credit, someone with poor credit can pay $50,000 more in interest on a mortgage. Over an entire lifetime, you could end up paying over $200,000 more in unnecessary interest just because of bad credit.
