Something tells me you won't be working 4,060 hours to do so - 80 hours a week year round.If it is a more active rental model that it is not considered "rental" income, then you would need to put in at least 100 hours with that being more than anyone else (employees, contractors, management company, etc), or you would need to put in at least 500 hours.So your "quick" question is actually fairly complicated.

These markets provide budget-friendly housing options for single-family homes, small multifamily properties, and rental properties.

Is that an option?

I did not want to move or sell anytime soon but fear that this option has been taken away from me.

The 2nd part of the question is which option maximizes the true revenue potential of the property ?
