A home is as necessary as breathing and eating. No one can go through there life without having a place to call home. A place where they can return at the end of the day, leaving the worries of the world behind, and cherish the moments of tranquility with their family. Many people work their whole lives to save enough money to one day have a place of their own they might be blessed to call home.
Unfortunately, in the US, the maintenance of even an average house is not exactly cheap. There is always risk of damage. Accidental damage, such as fire started by short circuit can cause much harm. The houses or private properties built by the rivers in the mountains or by the sea are constantly at a risk of flooding, either by melting snowcaps, heavy rainfall or rising tides. Then there is a risk of theft or sabotage by some nerdowell rapscallion.
A good Home Insurance policy covers your losses in case of any of the mentioned situations and more. It can help you for reconstruction in case of property damage, pay for mortgage or cover the losses suffered from theft of utilities inside the house.
It is not exactly legally mandated for every citizen to have a home insurance. But that in no way should demoralize a capable individual to avail this service. For you never know when you may land in a situation where you need to rely on it.
