May an unlicensed person call to set appointments for a broker?

An unlicensed person can indeed make calls to set appointments for a broker, specifically to schedule showings for listed properties. This is permitted as it falls under the category of clerical tasks or administrative support, which do not require a real estate license. The primary responsibility of the unlicensed person in this scenario is to facilitate the broker's activities by coordinating appointments with potential clients or showing properties that are already listed.

The role they play is purely supportive, meaning they are not engaging in any actions that would define real estate practice, such as discussing terms of sale or providing advice—activities that necessitate a real estate license. Instead, their actions help streamline the process for the licensed broker, who retains the authority and responsibility over all transactions.

The other choices suggest limitations that do not accurately reflect the regulatory framework allowing for this type of administrative duty by unlicensed individuals. Therefore, the allowance for making calls related specifically to setting up showings aligns with the operational structure that differentiates between licensed and unlicensed activities within real estate.
