Las Vegas 4 plex insurance question

[Rodney Campbell]

I am in the Las Vegas market and I would like some insight on 4-plex insurance.  The duplex and tri-plex are in line but my 4-plex units seems extremely high on the premiums.  I am basically insuring for for cost value amount (not current replacement) and the rates are still very costly.  Units in question are 2 story.

Thanks in advance for any information.
