Although any closing costs are potentially negotiable, and reflect along with the price, a basic rule of supply and demand, it is good to keep in mind the interests of the parties and some common traditional ways of handling them.
as a buyer you obviously want to pay for your inspections;
sellers pay to insure buyer's ownership interest in the estate as a good faith;
property taxes usually get prorated between the parties as of the date of closing, etc.
All of the above is common but not set in stone. Moreover, in most of the new developments where the seller is the builder, a buyer would be offered a customized developer's contract that might have all of the closing costs on the buyer's side. That is because the developer works in their accounting with the net proceeds of the sales, and the way to handle such situation for the buyer is to ask for credit on the purchase price itself (which might be helpful down the line with lower property assessment).
Don't hesitate to approach an experienced broker with a specific situation for a pro opinion.
