Answer: -Sadly, the score is different between agencies and they have conflicting criteria to set a a score. Equifax and Experian have mine at 813 and 819 respectively, but TransUnion has me at 774 because I don't have enough premium credit cards (I have two Visas) and I have too many inquiries (I have two). I have higher scores with the others because I don't have too much revolving credit nor do I have a lot of inquiries. So no matter what I do, one of them will ding me for it.Scores range from 450 to 850, so 650 would be the average and is considered good, but depending on who you ask, your mileage may vary. -Sometimes the definition varies depending on what the score is being used for and the specific negative credit ratings. Overall, a score of 660-680 is fair, above 680 is good and above 720 is excellent, in my experience. The entity requesting the credit score often queries all three Experian, TranUnion and Equifax and they take the middle score as your score. -Yes, your scores will all be different with each agency.. mine has a huge span between one and the other ... it can be like 580 with one, 620 with another 650 with the other. Same info basically. Mine is around 624 and is considered "fair" 350 is the lowest. 850 is the highest. My guess is that good would be somewhere around 650-700+Lots of good info at myfico.com and I'd recommend the Suze Orman FICO Kit ... it's an excellent resource.
