What disqualifies a house from financing?

[Natalie Kolodij]

I know that a house needs to be livable for most FHA financing ect....

I'm looking for my first live-in flip and I'm basically looking for the crappiest house that will qualify...

Is there a list of specific things that will disqualify it? I don't want to waste time trying to jump on a house that's a good deal because it's a fixer, but find out it's too much of one because of reason x,y,or z to qualify for financing. 

Any resources would be greatly appreciated!
