Multi-family Investment Property, Insurance Needs

Hello BP community, 

I am under contract on my first investment property, a tri-plex in the Fox Valley. 

The property will not be owner-occupied, and thus I understand "Homeowners" is not the appropriate insurance type. While reading BP forums, a post referenced ""Dwelling/Fire" (also called Landlord by some carriers) Policy". I am unsure of the amount or type of coverage is appropriate or safe, and I fear my greenness will lead me to either over-pay/over-insure or underinsure.

The topic of investment insurance is extremely foreign to me and so any information would be extremely helpful.  Is there anyone in the Fox Valley/Wisconsin area that has information or an agent referral?

Building Replacement/Rebuilding costs vs Depreciated Value, adequate coverage for loss of rents, optional coverages that may be important(Water Backup, Personal Injury Protection, Equipment Breakdown, Utility Line coverage,...)

Thanks so much!
