Keeping a household inventory can protect you in the face of an emergency. A big ticket item inventory can be essential for your insurance in the event of a claim. A small item inventory can save you from re-purchasing items that you already own. This kind of goes along with organizing your stuff. Keep your big ticket item inventory somewhere that you can get to in the event of a loss of your home (either in a fire box, on-line protected storage, or not in your house). This inventory can save you time, stress, and money during a difficult situation.
