When a manufactured home is sold or transferred on or after March 1, 1990, and when all ownership in the manufactured home is transferred through the sale or other transfer of the manufactured home to new owners, the manufactured home shall be real property when the new owners eliminate the title pursuant to this chapter. The manufactured home shall not be real property in any form, including fixture law, unless the title is eliminated under this chapter. Where any person who owned a used manufactured home on March 1, 1990, continues to own the manufactured home on or after March 1, 1990, the interests and rights of owners, secured parties, lienholders, and others in the manufactured home shall be based on the law prior to March 1, 1990, except where the owner voluntarily eliminates the title to the manufactured home by complying with this chapter. If the title to the manufactured home is eliminated under this chapter, the manufactured home shall be treated the same as a site-built structure and ownership shall be based on ownership of the real property through real property law. If the title to the manufactured home has not been eliminated under this chapter, ownership shall be based on chapter
46.12 RCW.
For purposes of perfecting and realizing upon security interests, manufactured homes shall always be treated as follows: (1) If the title has not been eliminated under this chapter, security interests in the manufactured home shall be perfected only under chapter 62A.9A RCW in the case of a manufactured home held as inventory by a manufacturer or dealer or chapter
46.12 RCW in all other cases, and the lien shall be treated as securing personal property for purposes of realizing upon the security interest; or (2) if the title has been eliminated under this chapter, a separate security interest in the manufactured home shall not exist, and the manufactured home shall only be secured as part of the real property through a mortgage, deed of trust, or real estate contract.
