Bidding dates are not good practice. Standard of Practice 1-6 states, “REALTORS® shall submit offers and counter-offers objectively and as quickly as possible.” This Standard of Practice supports Article 1 of the Code of Ethics which reads in part “...REALTORS® pledge themselves to protect and promote the interests of their client.” These are the two principals from the Code of Ethics are directly relevant to the question.
Additionally, an agent may wonder, is there a reason why the offer can not be submitted in the three days prior to Friday? A good example of a compelling reason why the offer could not be submitted until Friday is that a client is traveling abroad and is unreachable until they return on Friday. A poor reason would be an agent who only entered these remarks into MLS in order to try to generate "buzz" and never discussed with his client the issue of delaying the submission of offers until a specific time and day. Most reasons will probably fall between these two extremes
Please remember, that submitting an offer is not the same as doing a formal presentation of contracts. For the purpose of the Code of Ethics, submitting an offer is simply providing the client with information about the offer.
An agent could submit an offer to a client via a fax, voice mail, or email mail message notifying the client that an offer was received, providing a brief description of the relevant terms of the offer and informing the client that arrangements can be made to formally review the full contract at a later time and date prior to ratification. This would likely be sufficient to show that an offer was submitted. A dual agent who intentionally delays informing the seller about one offer that has been received so that he can meet with his own buyer clients in two days and write a competing offer may be failing to submit the offer quickly and objectively.
Others may argue that holding off on submitting an offer does not harm the clients interest and may actually help the clients interests if the buzz that is generated leads to more competing offers. However, the intention here is that agents must keep their clients informed about relevant information regarding the property or the transaction. Please keep in mind that it is very difficult to justify withholding information from the client. In most cases, it may be assumed that withholding information from a client violates an agent’s duty to protect and promote the interest of the client.
In summary, the offer has to be submitted "as soon as possible". Regardless of the remarks that are entered into the MLS listing, if it was possible to submit the offer before Friday, it must be done.
