Not sure if I should start looking at other houses or not

The fraternity is just not into you.
For whatever reason, someone or a group people have decided to arbitrarily apply different standards to different people. Even if you stick around and make a 3.0, who's to say they aren't going to turn around and say that you need a 4.0 to be intitiated now? Move on.
As for checking out other fratentities, you won't know unless you try. Like others said, campus culture, how the fraternity you are associated with now is viewed, and your grades may be determining factors. If you have friends in other fraternities, talk to them and see what kind of feed back you can get from them.

At this point it sounds like you could never be completely comfortable in this fraternity without worrying about who was on your side, and who was not. It also sounds like this is another case of too-fast growing pains with some internal differences between members and maybe you being made a scapegoat for "old XYZ" vs. "new XYZ" which isn't fair and sucks, but that's life.

Have guys in your situation (associated with a group, to the point of living in-house, for over a year) successfully gone on to pledge a different fraternity at your campus? That is what you want to look at.
