Why must salespersons determine if a home is linked?

Salespersons must determine if a home is linked in order to alert potential buyers. By identifying whether a property is linked, salespersons can inform buyers about any shared walls, utilities, or other aspects that may affect their decision to purchase the property. It is crucial for salespersons to provide complete and transparent information to potential buyers so that they can make informed decisions about the property. This aligns with the ethical responsibility of real estate professionals to act in the best interest of their clients by providing full disclosure about the properties they are selling. Therefore, the correct answer is C: To alert potential buyers.
