TransUnion and Equifax sell both FICO and consumer scores. Experian sells only consumer scores (they stopped selling FICO scores to the public a few years ago). Consumer scores I guess are not worth your trouble as no lenders use them. They are also usually higher than FICO scores. Most mortgage lenders use the classic FICO score, which is what you get at MyFico.com. But then again as I mentioned before, different lenders use different scores depending on what you are trying to purchase.
I’m a little confused about all this myself. I’m currently signed up for Experian’s monitoring service, but I’m going to cancel it this month after I apply for a car loan. I guess if you are going to sign up somewhere, it should be at myfico.com.
If you find out more about all this let us know.
