When making an offer for property, is the listed price negotiable

[Deion J Shields]

I'm currently looking at a property that won't allow us to go inside and inspect until we give an offer. I don't want to give an offer of the full listed price without first inspecting the inside so i suggested throwing a lowball offer just to see if the seller will take it or we can at least negotiate from there. However, my agent is deeply advising against it because the other houses in the area have closed at about the same price and the seller has another offer of the full price already. I guess i'm asking is property pricing negotiable from the get go or is it pretty much, you pay the listed price and negotiate the closing costs (termite inspections, etc.)?
