I think it's enough to stay on top of what's going on in the house and deal with problems as they appear or even before. Old drafty houses are a bit more resilient because they can dry out relatively quickly. New houses with stuff like OSB (chipboard) will just soak up moisture and "tell you" in a variety of ways that something is wrong. Like mold. If it appears, you got a moisture source that needs to be discovered and dealt with. Crawlspaces need to be encapsulated and have negative pressure. It's amazing how simple stuff like water leaking from a gutter can find it's way into a house with even the smallest gap at a window interface or if the drainage is bad where the house meets the ground.
