Insurance Policies for Multiple Properties

[Kaylan Field]

So, I've been trying to keep all of my properties, vehicles, etc with the same insurance company for bigger discounts, obviously. However, I've been told by more than one company that I can only have 4 landlord policies and anymore than that I either have to switch to a commercial policy or insure additional properties with another company. I have a few of them in LLC's, and I have an umbrella policy as well. How do people that have many properties insure them all with the greatest benefits for discounts? TIA.
