Finished rooms in the attic are a whole other topic. Most homes don't have finished attics.
If a home is constructed properly, the floor of the attic (ceiling of the room below) is insulated sufficiently, and the space in the attic should have adequate ventilation so that it isn't much different than ambient outdoor temperature. When the space heats up in winter, it indicates that there isn't adequate insulation on the floor, and that there isn't adequate ventilation. You don't want snow melting off the roof (an indication of the 2 problems mentioned). You also don't want it hot as hades in the summer because that reduces the longevity of an asphalt shingle roof.
At any rate, I requested the intake/ventilation be inspected and fixed by a licensed contractor, and the sellers accepted. One less project for me to tackle when I move in.
