What must be included on a broker's website according to licensing law?

The requirement for a broker's website to include the last date when the property information was updated is crucial for ensuring transparency and accuracy in real estate listings. Providing this information allows potential clients and visitors to understand how current or relevant the listings are. This date helps buyers and sellers gauge the reliability of the information presented, which can significantly impact their decision-making process. It reflects adherence to ethical standards in real estate practices, as accurate information is critical in building trust within the industry.

The other options, while important in various contexts, do not specifically align with licensing laws concerning the necessity of updating information on a website. Contact information is essential for facilitating communication, but it is not legally required in the same manner as displaying updated information. Similarly, while having a list of property addresses and mortgage lender information could enhance the user experience, they are not required by licensing law for the operation of a broker's website. Thus, the emphasis on the last update date serves as a safeguard for both the broker and the consumer, emphasizing the importance of current and reliable information.
