Must the money be returned to the tenants after the house was partially damaged and they left it, even though the contract was for 6 months?

The majority of jurists agree that a lease contract is binding on both parties and can only be terminated by the expiration of the term, the fulfillment of the purpose, or a reason that permits its termination. If a significant defect occurs in the leased property that prevents its use, the lessee has the right to terminate the contract, and the rent corresponding to the remaining period must be refunded. However, if the defect is insignificant and does not prevent the use of the property, the lessee does not have the right to terminate the contract; rather, he may demand repair. If the lessor refuses to make the repair, the lessee then has the option to terminate the contract.
