Not that I'm complaining, since I may be in the market for a HELOC, but I'm puzzled by the differences. My FICO8 scores are as follows:
FICO 8 - EX 677, TU 659, EQ 648
Mortgage - EX 706, TU 664, EQ 678
My TU mortgage score is close to FICO8, but the EQ and EX mortgage scores are about 30 points higher. Any particular reason why?
The only thing that occurs to me is I have a fairly high number of inquiries; that may be weighed differently for the mortgage score. I also have a fairly thin file, particularly for TU. I have a 9 year old BK7 that resulted in my mortgage completely disappearing from all 3 CRAs, though it is still in force and my recent payment history on that is good.



30 points really isn't much across different scoring models to be honest. There are members on here (SJ I believe is one of them) that have spans of some 100 points between scores with the same input data.
There are others that will be able to provide more detail but each type of score looks at the same data a bit differently. Much of what we discuss here are data points on Fico 8. Not sure if the MTG forum has more data points on MTG scores.
What I do know is that MTG scores really like minimal # of accts reporting a balance. I believe this is for all accounts, not just revolvers. When there is sometimes no movement in my F8 scores I typically see movement in my MTG scores when I reduce the # of accounts reporting a balance. MTG scores seems to also frown a bit more on new accounts/inquiries (credit seeking). Both of these is the reason it is suggest to not open new accts within a year of seeking a MTG and to execute the AZEO method when the lender is ready to pull your MTG scores. The opposite of that is when a new account or inquiry hits a threshold the reward can be greater than F8.
Looking at your factors/comments/remarks (depending on where you get your scores) - which usually appear under your scores, may also shed some light as to what each score is looking for which may help you answer your question, based on the specifics of your profile.

Yes, even greater than 100 points. E.g., on my last pulled report the span is 132 points from highest to lowest.
BTW my mortgage scores are invariably much lower than my FICO 8's and 9's, the opposite of OP's experience.
