Are you permitted to modify the tiles or paint the wall? A majority of landlords stipulate that the apartment must be restored to its initial condition when the tenant moves out. Some owners refuse to allow any form of decoration or changes to be made without their permission. Others have a clause contained in the lease stating that the tenant can decorate or make changes to the property if and only if they will patch, repair and repaint the property back to its previous condition. Be careful here to prevent losing your security deposit.
