This Old House (multifamily) Improvements for cheaper Insurance

[David A.]

So I am about to be a proud new landlord and am wondering what others have done to lower their cost of insurance on older (1900 ish) multifamily rentals. This will not be a house hack just a good old fashioned investment property. Let me explain what I think is impacting the insurance rates. I would love to hear your thoughts on where the biggest bang for the buck on improvements would be to decrease the insurance rates. 

1. Old house - don't think I can really change this one.
2. Central Nebraska so wind and hail - I don't plan on moving the house though
3. Some out of date electrical - has breakers but some knob and tube
4. Some out of date plumbing - galvanized
5. Exterior does need a good paint job and some gutter and soffit repaired. 
6. Boiler/Steam Radiator heat - boiler is ~12 years old
7. Some floor joists have minor cracks - this should be easily fixable right?
8. Some windows are cracked and missing the glass

Can't wait to hear your thoughts...
