(iii) Require the seller of a mobile or manufactured home to deliver to the buyer prior to the sale: (A) A completed property transfer disclosure statement in accordance with chapter
64.06 RCW, unless the seller is exempt or the buyer waives his or her rights under chapter

(b) The department may adopt a rule that allows parties to enter into a conditional sale of an altered mobile or manufactured home.
