In all of this, it is important to realize that you do not have one credit history; you have three. They are maintained by Experian, Equifax, and Transunion, and can contain very different information. Because of this, there is a separate FICO credit score for each one of them. Any effort on your part to build a good credit rating should involve a review of all three reports. You are entitled to a free copy of each once every 12 months, so you should check it yearly and make sure it is accurate. If you have any questions on this subject, please feel free to contact me.
