Usually, one of the biggest investments people make during their lifetime is buying a home, so taking care of it is a high priority because there are so many people who can afford to invest again if something happens to their capital. And they are few to build their own house.
Of course, if a person has a mortgage on their title deed, lenders usually force that person to buy home insurance, but if the mortgage has been settled, it is recommended that you continue to get home insurance.
