So I would get calls occasionally from clients asking if they are getting all the discounts and the best price. Now the thing is, insurance rates are filed with the state so discounts varies from company to company. That being said, most if not all carriers offer a multi-policy discount. So said you have an auto policy and you added a renter's insurance. By having two different type of insurance policies with 1 company, you get discounts on each of them. Also, occasionally a policy actually pays for itself. I have seen cases where the total premium is lower for both a renter's and an auto rather than just an auto policy.
The multi policy discount can result in some real savings; in many cases, it can amount to hundreds of dollars per year. The discount itself often ranges from 10% to 20% off the total price. Just like the bundling you see with phone, cable and internet; the more you have with one company, the more you save.
