Final answer:
A broker using an outside source for square footage information in marketing materials must disclose the source. It helps to maintain transparency with potential buyers and can protect the broker from liability.
Step-by-step explanation:
A broker using an outside source for square footage in a marketing brochure must disclose the source of the information. Although different jurisdictions may have different requirements, it is commonly accepted that real estate brokers should provide the source when they use third-party information in their marketing materials. This is a best practice to ensure transparency and maintain trust with clients, as square footage can be a critical factor in real estate transactions. It is not typically required that a broker have a professional appraiser measure the square footage unless it is mandated by state law or requested by the client.
Brokers are responsible for the accuracy of their marketing materials, but it is also important for buyers to conduct their due diligence. The inclusion of a disclaimer stating that the square footage may not be accurate is also a common practice that can protect the broker from potential liability.
