But whether it constitutes a jump order depends on the specific agreement between you and the intermediary. If you have signed a written agreement with the intermediary that you can't bypass the intermediary and deal directly with the landlord within a certain period of time, then your behavior may have violated the agreement. If there is no such agreement, or the intermediary does not provide enough services (such as providing a contact information without substantive intermediary services), then your direct contact with the landlord may not constitute a jump order.
In practice, in order to avoid disputes, it is best to communicate clearly with the intermediary and understand the rights and obligations of both parties. If you decide to deal directly with the landlord, you should also consider the inconvenience that may be brought to the intermediary and properly handle the relationship with the intermediary. If in doubt, you can consult a legal professional to ensure that your actions are legal and compliant.
