What type of brokerage business specializes in selling or leasing income-producing properties?

The correct answer is commercial brokerage because this type of brokerage specifically focuses on selling or leasing properties that are used for business purposes and generate income. These properties can include office buildings, retail spaces, warehouses, and other commercial entities. Professionals in commercial brokerage are trained to navigate the unique market dynamics, financial aspects, and legal considerations that come with income-producing properties, making them experts in this niche.

Residential brokerage, on the other hand, is centered on properties intended for personal living, such as single-family houses or apartments. Industrial brokerage specializes in properties used for manufacturing and production, which may not primarily focus on income generation in the same way that commercial properties do. Investment brokerage is more aligned with helping clients make decisions about buying investment properties but may not specifically focus on commercial or income-producing real estate in the same manner as commercial brokerage does. Thus, the focus on generating income through business-related properties distinctly defines commercial brokerage.
