No amendment shall be required, however, if the seller takes whatever corrective action is necessary so that the accuracy of the disclosure is restored, or the adverse change is corrected, at least three business days prior to the closing date. Unless the corrective action is completed by the seller prior to the closing date, the buyer shall have the right to exercise one of the following two options: (a) Approving and accepting the amendment, or (b) rescinding the agreement of purchase and sale of the property within three business days after receiving the amended real property transfer disclosure statement. Acceptance or recision shall be subject to the same procedures described in RCW 64.06.030. If the closing date provided in the purchase and sale agreement is scheduled to occur within the three-business-day rescission period provided for in this section, the closing date shall be extended until the expiration of the three-business-day rescission period. The buyer shall have no right of rescission if the seller takes whatever action is necessary so that the accuracy of the disclosure is restored at least three business days prior to the closing date.
     (2) In the event any act, occurrence, or agreement arising or becoming known after the closing of a residential real property transfer causes a real property transfer disclosure statement to be inaccurate in any way, the seller of such property shall have no obligation to amend the disclosure statement, and the buyer shall not have the right to rescind the transaction under this chapter.

Closing is deemed to occur when the buyer has paid the purchase price, or down payment, and the conveyance document, including a deed or real estate contract, from the seller has been delivered and recorded. After closing, the seller's obligation to deliver the real property transfer disclosure statement and the buyer's rights and remedies under this chapter shall terminate."
