Recommendations for Vacant and Unoccupied Insurance

[Isaac Passmore]

My lender is requiring that I obtain Vacant insurance. Does anyone have any recommendations for where to find this for the greater Washington DC metro area? Specifically Prince George's County MD. 

I have never heard of this type of insurance before but is there anything unique about it other than no one can live in the property for coverage to be effective? Is there an area where I can read more about the various insurance products that may come up concerning real estate transactions?
