Most insurance companies do not limit themselves to providing one type of coverage. Many will offer life insurance, auto, dental and health as well as affordable homeowner's insurance. Rather than spreading your coverage out over several companies, find out what you would have to pay if you consolidated your insurance.
You should be able to get a significant discount if you have multiple accounts with one company, like auto, life and home insurance. Take a look at QuoteScout.com to see the benefits of using one company for your insurance needs.
Some cases might prove worth it, some might not. But at least you'll know for sure rather than continuing to pay more than necessary when you could have avoided it. Whenever you update your insurance policy on your home, ask them what their rates are like for other things and if there is a financial benefit to switching them over to one company.
