Benefits for Investors:
Two sets of rental income producing a higher yield, which should ultimately make this a cash flow positive investment;
Lower risk associated with vacancy periods as there is a secondary rental income;
No strata fees, as the dwellings remain on the same lot/title.
One set of Council rates and water rates, as opposed to strata titled dwellings.
Market rents for each dwelling are more affordable to rent than a typical 4 bedroom investment property, which increases the demand for this type of property.
