Final answer:
The option that is NOT an example of an interest in real estate is a real estate agent's right to advertise a property for sale, as it is a temporary professional privilege and not a true property interest.
Step-by-step explanation:
The question asks which of the following is NOT an example of an interest in real estate. An interest in real estate generally refers to rights associated with the ownership or use of a property. Of the options provided:
