Final answer:
The type of income not generated from property ownership is earnings from services rendered, which is labor income, unlike dividends, interest, and gains from sales of property.
Step-by-step explanation:
Among the types of income listed, the one that is NOT generated from owning property is earnings from services rendered. This type of income is associated with the labor resource, not with property ownership. Conversely, dividends received from corporate stock reflect income generated from owning financial assets, interest income from a certificate of deposit is the result of owning financial products in a bank, and gain on the sale of land comes directly from the sale of real estate property. These latter three are typical examples of income derived from owning property or capital.
