Protecting your new home with insurance is a must. How well you do that depends on the details of your policy. And while you are not required by law to have homeowners' insurance, mortgage lenders require that you do.
A standard policy will suffice in most instances. It protects against several natural disasters and catastrophic events. However, it will not guard against earthquakes, floods, war and nuclear accidents. The policy can be expanded to include these disasters as well as coverage for such things as workers' compensation. In fact, the lender may require that you purchase flood or earthquake insurance if the house is in a flood zone or a region susceptible to earthquakes.
