You have entered into a contract to purchase a new house, and the closing is scheduled for next week. It is typical for some last-minute bargaining to occur at the closing table where sellers often try to tack on extra fees. You have three options for closing: attend yourself, send an attorney authorized to close only per the previously negotiated terms, or pre-sign all the closing documets per the current terms and not attend the closing. Which of these would be most advantageous from a bargaining position?
