Credit repair is critical to saving money on insurance, loans, and credit cards, but that's not the only reason to repair your credit. A better credit score opens up new employment opportunities, even promotions and raises with your current employer. If you dream of starting your own business or just want the security of knowing you can borrow money when you want to, you should repair your credit sooner rather than later.
That is for you to decide. You do have to weigh the certainty that your credit score would take a hit (and some time to rebuild) against the advantage of a program that will allow you to make progress and pay off your debts. A bank loan is another option. You could check on the interest rate . . . but you should do this knowing you will not run up credit card balances again. Otherwise, you end up in an even worse situation than you are in now.
Each time you apply for credit is listed on your credit report as a “hard inquiry” and if you have too many within two years, your credit score will suffer. In general, a consumer with good credit can apply for credit a few times each year before it begins to affect their credit score. If you’re already starting with below-average credit, however, these inquiries may have more of an impact on your score and delay your ultimate goal of watching your credit score climb.
