help for the five unit property insurance quote

[William Zhou]

Hi, Everyone

I will close a 5 unit property and am looking for the insurance quotes. Currently I already obtained three quotes: $3000, 2200, and $1900.  (all of them are $1 million personal injury, $1000 deductible).  All these prices are little shock to me since this is the first commercial insurance I have. The property is in North Carolina. To  your knowledge, are these quotes reasonable? If not what is your expected price? Or should I quote more? 

If anyone can recommend a good insurance agent in Charlotte area (NC) I will highly appreciate.

Thanks
