Unlike some of their competitors, MSI Credit Solutions doesn't expect you to handle any of your disputes or other documents needed to manage your credit repair process. They draft all of the necessary letters and make contact with the credit bureaus, collections agencies, and other creditors on your behalf. And, as part of their credit repair process, they also help you to establish appropriate lines of credit to build your score in a positive direction while removing negative items from your credit history.
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).
