With whom may commercial dealers engage in multiple listing of units titled with the state?

The correct choice highlights that commercial dealers may engage in the multiple listing of units specifically with other dealers. This arrangement facilitates collaboration among dealers, enhancing visibility and marketability for the units being listed. By working together, dealers can share resources, access a broader client base, and potentially expedite sales processes.

It's important to note that while real estate brokers might play a role in assisting with property transactions, the option specifically focuses on the interaction between dealers. Moreover, licensed contractors primarily focus on construction and renovation work rather than sales or listings of commercial units, making their involvement in multiple listings less relevant. As for the notion that multiple listing is prohibited for commercial coaches, this does not align with the regulatory framework that allows dealers to list units for sale or promotion effectively.
