There must be a Seller's Residential Real Estate Disclosure for all of the properties except,

A Seller's Residential Real Estate Disclosure is typically required for residential properties to inform potential buyers about the condition of the property and any known issues. However, this requirement does not apply to all types of real estate.

The correct response highlights that a commercial building is excluded from this requirement; commercial properties are generally not considered residential real estate. The disclosure rules are specifically designed for residential properties, which typically include single-family homes, duplexes, and similar dwellings designed for living. A commercial building, on the other hand, is intended for business use, such as offices, retail spaces, or warehouses, and thus does not fall under the same legal obligation to provide a Seller's Residential Real Estate Disclosure.

In contrast, a multi-unit residential property such as a four-unit apartment building, a single-family home—even one that is ten years old—and a duplex are all considered residential properties and require the disclosure. This is significant because the disclosure helps protect buyers by providing vital information regarding the property they are considering purchasing, which is not applicable in commercial transactions.
