There are so many variables, that an insurance agent needs to get a lot more detail on the property before you can expect an answer that is close.
The age of the home, location, construction type all play a part.
A hip roof is cheaper to insure than a gable roof.
Newer homes built to higher construction code cost less to insure.
Block construction as opposed to wood frame.
An older home may have had improvements made that would reduce the costs.
Even your credit score will affect the insurance prices.
You can call an insurance agent and give them the property ID number. They then pull the tax records and county data to determine original construction and improvements. Depending on the age of the home, a wind mitigation and/or a four point inspection will be needed.
