The fact that the two scores were pulled three weeks apart can make a difference, but most likely it is because two different versions of the Fico scoring model were used. The TU Fico score that customers purchase from MyFico is the 1998 version, and the TU Fico score that your broker pulled is probably the 2004 version (you could ask him what the exact name of the TU score was, to confirm that fact). Many other people have found themselves in the same situation as you, and in most of these cases, the 2004 score tends to be lower than the 1998 score, which is an unpleasant surprise.
Fico and TransUnion need to come to an agreement as soon as possible to allow the 2004 version to be made available at MyFico and at transunioncs.com. This situation has gotten more and more absurd during the past two years ...
