Which of the following is typically included in a multifamily property?

Multifamily properties are defined as residential buildings that contain multiple separate housing units, allowing multiple families to reside in the same structure. Apartment units fall squarely into this category, as they are designed to accommodate individuals or families living in separate units within a single building or complex. The primary function of multifamily properties is to provide residential space for tenants, making apartment units a quintessential example.

Other types of properties, such as single-family homes, professional office spaces, and commercial storefronts, serve different purposes and are not classified as multifamily. Single-family homes are meant for one household, while professional office spaces and commercial storefronts cater to businesses and do not provide residential accommodations. Therefore, apartment units are the correct answer as they align directly with the definition of multifamily properties.
