Now let's calculate rental income from a spare room or granny flat, up to 20 commercial units. Determine your vacancy factor, property management fees including advertising, accounting, and collection costs; as well as anticipated rental increases, depreciation, even your own personal benefit for using the property (you would have to pay rent and live elsewhere)!

Propvest takes all this into consideration when it calculates your total annual cashflow and Net Operating Income (positive or negative)!
