(2) For the purposes of this section, the term “durable equipment” includes only mechanical refrigerators, air-conditioning equipment, mechanical laundering machines, heating and cooking stoves and ranges, and, in addition, in the case of apartment houses and hotels, room furniture and furnishings.
(3) Prior to the acquisition of a chattel mortgage hereunder, items of property to be included therein shall be separately appraised by a qualified appraiser and the fair market value thereof determined. No such chattel mortgage loan shall exceed in amount the same ratio of loan to the value of the property as is applicable to the companion loan on the real property.
