1. If a lease is concluded for a lump-sum rent and the number of units of the leased property is stated without specifying the rent for each unit, and the units are found to be more or fewer, the rent shall be the amount specified in the contract, with no increase or reduction. In the event of a deficiency, the lessee shall have the option to rescind the contract. 2. If the contract specifies a rent for each unit, the lessee shall be bound by the specified rent for the additional units, and the lessor shall be bound to reduce the specified rent for the missing units. The lessee shall have the option to rescind in both cases. 3. If the amount of the deficiency or excess is minor and has no effect on the intended usufruct, the lessee shall have no option.
