Which of the following is NOT a type of real estate investment?

The question asks which option is NOT classified as a type of real estate investment. The correct reasoning behind identifying retail as a non-category in this context lies in the fundamental classifications of real estate. Typically, real estate investments are categorized into residential, commercial, and industrial sectors.

Residential real estate includes properties meant for dwelling, such as single-family homes, apartments, and condominiums. Commercial real estate pertains to properties used for business purposes, which can include office buildings and shopping centers. Industrial real estate encompasses properties used for manufacturing, warehousing, and distribution.

While retail is often considered a subset of commercial real estate, it is not regarded as a standalone category within the broader classifications of real estate investment. Therefore, selecting retail illustrates an understanding of viable real estate sectors and their distinctions.
