Which of the following does not qualify as a type of real estate agent?

A consolidated agent is not recognized as a type of real estate agent within the industry. The term "designated agent" refers to a specific individual within a brokerage who is authorized to represent a client, typically in a transaction involving multiple agents. A facilitator, also known as a transaction broker, aids both parties in a transaction without representing either side in a fiduciary capacity. A sub-agent acts on behalf of the listing agent to help sell a property but is still considered to be working under the guidance and authority of the main listing agent. In contrast, "consolidated agent" is not a standard term used in real estate, making it the correct choice as it does not qualify as a recognized type of real estate agent.
