Should I live in one unit and rent the other in Johns Creek?

Living in one unit of a Johns Creek two-family while renting the other can qualify a buyer for owner-occupant financing terms that are often more favorable than an investment property loan, which is a genuine financial advantage over buying it purely as a rental. It also means being your own property manager living on site, which suits some owners more than others. Whether the specific numbers work still comes down to comparable rents and costs for that particular Johns Creek property.
