Is the landlord obligated to pay the cost of painting the apartment for the tenant who did not reside in it and refused to complete the rental agreement after painting it without the landlord's request?

If there is no agreement to compensate the tenant for the cost of painting, then the landlord is not obligated to anything; because the use of the apartment does not depend on new paint, and the apartment was rented in its current condition. In this case, the tenant is a volunteer, and he may take his tools. Neither the landlord nor the tenant is obligated to adorn or plaster, or anything similar, which can be benefited from without it, unless a condition is stipulated.
