Insurance on a 6 unit property in California

[Kurt Z.]

The property is 3 buildings each with 2 Townhomes. I received a quote from my primary insurance broker at State Farm. He carries my auto, home, umbrella, etc. He underwrote it as 3 residential buildings. Any reason not to go this direction? Can anyone suggest some good commercial carriers/Brokers in Northern California? Is there any good guidelines on cost per unit for small apartment buildings in California? I also want to include EQ insurance. Thanks!!
