Its hard to get an accurate quote. They can give you a rough idea, but for the most part, they usually look at the property claim history, flood history, etc. But they can surely give you tough ideas.

I would strongly advise getting yourself a certified Buyers Agent who understands what and how any particular house's final price will effect you when it comes to insurance, etc...do not take any seller's / listing agents word for anything...they are trying to sell the house, not get you to understand what it will really take to aquire and hold a house long/short term.
This seems to be a serious problem Uptown for some reason as insurance implications get harder for the average person to understand and some agents continue to befuddle potential buyers...so very much...buyer beware!
