First, most investors and owners of real estate related businesses are in one or more of the following situations1- they’re unable to duplicate their expertise that drives the ROI and they are at their personal max capacity as to time2- they’re obtaining high ROI by use of excessive leverage 3 - they’re obtaining high ROI by taking excessive risk4- they hit correct timing in the correct market, and this is not necessarily repeatable with any probabilityIn order for an investment or business to scale, we need the ROI (on a risk adjusted basis) to be sufficient to cover a PREMIUM risk adjusted return to passive investors; all expenses of managing the assets and the business, and a significant return to the “sponsor” providing compensation to him making the work, risk and time worth while. 

Duplexes are a little easier than 3-4 units with FHA since they don't have to meet self-sufficiency requirements.
