The amount of coverage you get is completely up to you. We recommend that you purchase coverage equal to or greater than what you estimated it would cost to replace your personal property if you lost everything, say in a fire.
Your Landlord may require a minimum amount of Liability coverage. If you have valuable items, consider upgrading your coverage option.
