Home insurance is essential in several situations. First, if you have a mortgage on your home, your lender will likely require you to have home insurance to protect their investment. Second, even if you own your home outright, it's crucial to have insurance to protect your property and belongings from unexpected events such as fire, theft, or natural disasters. Third, home insurance can provide liability protection in case someone is injured on your property. Additionally, if you live in an area prone to specific hazards like floods or earthquakes, you may need additional coverage beyond a standard policy. It's important to carefully consider the risks associated with your location and the value of your property and possessions when deciding on the right home insurance policy for your needs.
