What is a key requirement for real estate agents advertising properties in Pennsylvania?

In Pennsylvania, a significant requirement for real estate agents when advertising properties is that they must include the broker's name in the advertisement. This regulation is in place to ensure transparency and to provide prospective buyers with the appropriate context regarding who is representing the property. Including the broker's name not only enhances accountability but also helps maintain professionalism within the industry. It allows consumers to identify the authorized entity behind the marketing of a property, which is crucial for trust and reliability in real estate transactions.

The other options do not accurately reflect the key advertising requirement. For instance, providing clients' personal information poses privacy risks and is not a standard advertising practice. While a physical office may be necessary for a licensed business, it is not a direct requirement for advertising. Open houses are a marketing strategy, but conducting them is not mandated for all advertisements.
