Which of the following tasks can an unlicensed real estate assistant perform?

An unlicensed real estate assistant can perform tasks that do not require a real estate license, such as preparing real estate flyers. This task involves creating marketing materials that promote properties and can be done without the need for specific real estate knowledge or the legal authority required for licensed activities.

In contrast, negotiating contracts is a licensed activity that requires a thorough understanding of legal language and the implications of terms agreed upon, which is beyond the scope of an unlicensed assistant. Hosting an open house typically involves engaging with potential buyers and discussing property details, which is also a licensed function. Similarly, showing homes to potential buyers involves presenting properties, answering questions, and potentially negotiating terms, which again must be done by someone with a real estate license. Thus, preparing flyers is an appropriate responsibility for an unlicensed assistant because it is purely administrative and does not involve any real estate transactions or legal obligations.
