If you find information that is incorrect, you can file a dispute. Remember too, that items on your credit report that you don't recognize could also be potential signs of fraudulent activity — someone working to secure credit in your name for their own use. Make sure you're clear on items that could potentially be fraudulent, versus those that may simply be inaccurate.
Credit scoring models usually take into account how much you owe compared to how much credit you have available, called your credit utilization rate or your balance-to-limit ratio. Basically it's the sum of all of your revolving debt (such as your credit card balances) divided by the total credit that is available to you (or the total of all your credit limits).
If you have errors that can’t be verified: A little known fact about your credit report is that every detail in the report needs to be verifiable. For example, if you have a negative item on your credit report from a lender who was bought or went out of business, there is a chance that if the credit bureaus were to call to verify the information on your report, they would get no answer. In that case, they are required to remove it from your credit report. This is a loophole that credit repair services will use to raise your score.
Nearly 8 out of 10 credit reports have errors. That means, remove the errors and your score will most likely increase. Go through your credit reports very carefully. Especially look for; Late payments, charge-offs, collections or other negative items that aren't yours, Accounts listed as "settled," "paid derogatory," "paid charge-off" or anything other than "current" or "paid as agreed" if you paid on time and in full, Accounts that are still listed as unpaid that were included in a bankruptcy, Negative items older than seven years (10 in the case of bankruptcy) that should have automatically fallen off your report (you must be careful with this last one, because sometimes scores actually go down when bad items fall off your report. It's a quirk in the FICO credit-scoring software, and the potential effect of eliminating old negative items is difficult to predict in advance). Also make sure you don't have duplicate collection notices listed. For example; if you have an account that has gone to collections, the original creditor may list the debt, as well as the collection agency. Any duplicates must be removed!
Pay down current and past-due debts first. Don’t fall into the trap of paying off old debts by postponing payments of current debt. The late payment accounts are already reflected on your credit report and score. Keeping credit accounts current helps your score by having good credit sources that are older, rather than new. When paying off past debts, explain to your creditor that you are trying to become current and ask for help. Your creditor might:
If you have missed payments, get current and stay current: the longer you pay your bills on time after being late, the more your FICO Scores should increase. Older credit problems count for less, so poor credit performance won't haunt you forever. The impact of past credit problems on your FICO Scores fades as time passes and as recent good payment patterns show up on your credit report. And good FICO Scores weigh any credit problems against the positive information that says you're managing your credit well.
