Rental Property Insurance

[Fred Ramos]

Here's a question for all you insurance agents and landlords. I recently heard that I may be able to place all (4) of our rental properties under one insurance policy and that it would probably lower our overhead. I've searched all over but have not come up with anything. Are any of you using a homeowners insurance of this type? and if so, what is it called and who offers it?
your responses are greatly appreciated.
