You can buy a video camera for about $130 these days. Those can be worth thousands of dollars if your house was to ever catch fire. Why? You can keep a video record of all the things that you have in your home. That videotape becomes an insurance policy for your insurance policy. Don't keep the videotape in your house. You’ll want to store it somewhere that is safe like at a relative’s house. You don't want your records to be burned up with your stuff. Also, jewelry and art are not covered under normal homeowner’s policies. So think about what you have and if you need extra coverage for those types of pieces in your home.
