How does rental income work on a Cumming two-family or three-family?

A Cumming two-family or three-family property generates income from each unit separately, and the real return comes from adding up all the units' rents against the property's total mortgage, Forsyth County taxes, insurance and maintenance, not from looking at just one unit in isolation. Vacancy in even one unit can meaningfully change the math on a smaller multi-family property.
