Total seller closing costs run 4 to 6 percent, commission included alongside legal fees and adjustments, and that is the figure the seller is budgeting against, not a number the buyer sees on an invoice in a standard deal.
Where a buyer's representation agreement gets specific is in situations where no commission is being offered by the seller at all, such as a private sale, in which case the agreement's fee terms determine whether the buyer owes anything directly.
