A credit repair company initiates credit challenges to bureaus when they notice errors in your credit reports. Credit report disputes involve challenging credit bureaus, drafting goodwill letters to remove late payments and contacting data furnishers to verify old debts. Credit repair specialists review the results and, if necessary, escalate the dispute process.
The honest answer? Yes, and no. Credit repair is a great way to improve your credit score, if the problem is caused by a disputable error. If your credit score is poor because of a giant pile of debt — debt that you legitimately owe — then credit repair may not be the right solution. Determining which path to take will be based upon those considerations as well as any other factors that may be unique to your situation — and this is something only you can decide.
Scoring models consider how much you owe and across how many different accounts. If you have debt across a large number of accounts, it may be beneficial to pay off some of the accounts, if you can. Paying down your debt is the goal of many who've accrued debt in the past, but even after you pay the balance down to zero, consider keeping that account open. Keeping paid-off accounts open can be a plus in your overall credit mix since they're aged accounts in good (paid-off) standing. You may also consider debt consolidation.
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.
