Mortgage lenders pull all three of your FICO scores --Equifax, TransUnion, and Experian. (All FICO scores, but almost always different from one another, both because your reports are usually slightly different, and because each has a different FICO score formula.) So they will see your Beacon 5.0 (Equifax), your Classic Emperica (something like that) 98 or 04 (TransUnion), and your FairIsaacv2 (Experian.) Their Beacon will match the EQ you get here, if it's pulled at the same time, with no changes on the report. Their TU score will probably be a TU04, but we've only got the TU98 here. (Thanks, TU! 
) And the Experian won't match anything you've got, unless you join PSECU.
Of these three FICO scores, if you're the sole applicant, they will go with your middle score --not the highest, not the lowest. If you're applying with someone else, a spouse for instance, they will look at your middle score AND at his/her middle score, and go with the lower, whether it's your middle score or the other person's middle score.
