Just thinking out loud, I'd guess people living there would be an important factor since we produce quite a lot of water vapor, as do things like cooking etc. And when the house is cold, this has a tendency to condense on any surfaces. And humid porous surfaces (drywall) and even insulation will probably be a good substrate for mold.
