Property Insurance Estimation

[Tyler Jordison]

Hi There, 

I am having a hard time finding what a "good" or "conservative" number would be to use when calculating insurance on 2, 3, or 4-plex's to add to my expenses. I know I could go and get a quote each time, but that isn't really feasible when I'm in the general stage of focusing in on properties. Does anybody have any resources to help me find a good number to use at this macro view of property? 

Thanks so much!
