What do I need to know as a new Minnesota homeowner?

We are moving to the area in the next couple of months. I have never lived above the Mason Dixon so I haven’t lived anywhere with a real winter. What do I need to know about being a homeowner in the area?
What do I need to look for when selecting a house? What do I need to do to protect my home from the winter? What are my responsibilities as a homeowner, like snow shoveling and such? What would I never think about until I am in the dead of winter?
