(a) The seller of real property to which a new HUD-code manufactured home is permanently attached may give the initial purchaser a written warranty that combines the manufacturer's warranty and the retailer's warranty required by this subchapter if:
(1) the statement of ownership reflects that the owner has elected to treat the home as real property;
(2) the home is actually located where the statement of ownership reflects that it is located; and
(3) a copy of the statement of ownership has been filed in the real property records for the county in which the home is located.
(b) If a combination warranty is given under this section, the manufacturer and retailer are not required to give separate written warranties, but the manufacturer and retailer are jointly liable with the seller of the real property to the purchaser for the performance of their respective warranty obligations.
