Dual occupancy

A dual occupancy (or 'dual occ') is a single property title that contains two separate, self-contained dwellings - typically a main house at the front and a second smaller home at the back, or two attached homes. Investors target dual occs for the rental yield uplift: two rents from one mortgage, often pushing the property into positive cashflow territory in markets where a standard single dwelling would be negatively geared. Trade-offs include higher build cost, council planning friction (each council has different dual-occ rules), two tenants to manage, and the resale market is smaller because owner-occupiers typically want a single dwelling, not a divided one. Often confused with a duplex (which is two separate titles).
