#19: The mold.
This place is full of it! We noticed it on the celing when we moved in so we bought a dehumidifier (which we took out of rent by the way). It runs all winter long and most of the fall; great for our electric bill! All of our clothes feel damp and cold, plus its just gross to think of mold everywhere. I think there is no insulation whatsoever in here; also great for the bill. Im sure the walls are full of moisture, who knows what we have been breathing into our lungs for the past year and a half!
