Aubry purchased a washing machine, a freezer, and a refrigerator from Gateway Appliances on credit, giving Gateway a security interest in the appliances. The appliances were for Aubry's household use. Gateway did not file a financing statement. Six months later, Aubry had a garage sale and sold the appliances to Tam. Tam bought the appliances for her student rental property. Aubry left town owing money on the appliances. If Gateway can trace the appliances to Tam, can Gateway repossess the appliances?
