Which of the following is NOT required to disclose in a seller's disclosure notice?

The rationale behind the correct answer lies in the specific legal obligations regarding what must be disclosed in a seller's disclosure notice in Texas. The Texas Property Code outlines the requirement for sellers to disclose known issues with a property's condition, the general history of pest infestations, and other material facts that can affect the buyer's decision.

In this context, while sellers must disclose general property condition items and past pest problems, they are not obligated to disclose personal medical information regarding occupants, such as the health status or the cause of death related to the seller's son. This falls into a category of private information that is not considered relevant to the physical condition or safety of the property itself. Thus, disclosing a previous occupant’s death due to AIDS is not required, as it does not affect the property's value or condition in a way that is pertinent for a potential buyer.

This reinforces the principle that disclosure requirements focus on matters that can influence the property’s value or the buyer’s decision-making process, while personal details surrounding individuals' health or circumstances do not typically meet this threshold.
