Who must be a licensed Hawaii real estate broker or salesperson?

A licensed Hawaii real estate broker or salesperson is required for individuals who engage in activities that involve the brokerage of real estate. In this case, the correct choice highlights a caretaker who leases homes for multiple owners as someone who must be licensed. The key point is that the caretaker is actively involved in leasing, which is considered a brokerage activity. Leasing homes on behalf of multiple owners would necessitate the oversight and regulation that comes with being a licensed real estate professional, to ensure compliance with state laws and standards.

In contrast, other options, such as a resident manager of a condominium who does not handle rentals or a licensed attorney acting under a power of attorney strictly to convey real estate, do not require a real estate license because they are not engaging in real estate transactions in a brokerage capacity. The partnership selling a building owned by its partners doesn't require a license either since the transaction is between the partners directly rather than involving a brokerage service. Thus, it’s clear that activities like leasing on behalf of others, especially for multiple properties, cross the boundary into the realm that requires a real estate license.
