Multiple rentals - Insurance options?

[Thomas M.]

We own 2 single family rental homes and a 4 plex. We're about to purchase another single family home to rent. 

Seems like there should be more options when insuring multiple rental properties. Is there such a thing as a blanket policy vs having a separate policy for every property? I just don't know if other options exist or it just make sense to have a individual policy on each property. 

Seems I'm paying way too much for insurance, but it is what it is...someone enlighten me. Are their other options out there that are more cost effective?
