I have found it is usually the landlord who is responsible for most repairs and this is specified in the lease (barring tenant negligence or other stated reasons why a tenant would be responsible). However, in the case of a tenant being responsible for repairs and maintenance, does the tenant own the parts they used to repair an appliance or air conditioner or any other item that was attached to / included with the home? If they do, can they take those parts with them if the lease ends?
For hypothetical's sake, let's assume(Assume there is no clause in the lease that defines any item's expected condition before or after the lease term.)
