Called irwin union. They said it is kind of strange and they have seen this scenario harm other credit before.
The 2nd mortgage is indeed a 2nd mortgage but because of the variable rate it is reported as revolving credit. I'm gonna see if I can get it switched over. Bummer part is even after it is switched it might take a while to change on the score.
Appartently because I have little to no installment credit (gee, sue me for paying installment loans properly and on time) and the majority is revolving (with a large balance because the 2nd mortgage is almost all of it) that I'm getting slammed.
