Which of the following is NOT a type of residence listed?

A commercial building is classified differently from residential properties. In the context of real estate, residential properties are specifically designed for people to live in. This includes single-family houses, condominiums, and duplexes, all of which provide living spaces for individuals or families. A commercial building, on the other hand, is intended for business purposes, such as retail stores, offices, or any other type of commercial enterprise. Understanding these distinctions is crucial for auctioneers, as it affects the type of properties that can be sold or auctioned under specific residential real estate regulations and practices.
