Perhaps one reason is that the person renting the home believes their possessions are covered under the homeowner’s policy, however, this may not be the case so they should contact the homeowner to find out. Another reason for not having renter’s insurance is that someone may think it costs too much. Many policies are very affordable, though, and some even cost less than 20 dollars a month. There is also the belief that their belongings are not worth anything and so there is no need for coverage but, think about how much replacing those items would cost and it's easy to see how quickly that would add up.
So, if you are renting your home or apartment and still do not have a rental insurance policy, why not start to look at the different policies available to you. It's very likely you will find one that you can afford and that will cover you for those unfortunate unexpected disasters.
