Homeowners Insurance for a duplex in Indiana

Hello,

I just reviewed my homeowners insurance policy for my duplex, and noticed it will increase $130 per year, which starts next month if I choose to renew. I have been shopping around and was wondering what companies other investors trusted. Nearly every company I have called wants to insure both addresses separately. My current homeowners insurance policy is under one address, but covers both sides of the duplex. Any suggestions would be greatly appreciated. 

Thanks,

Chris
