Dual Key Investment PropertiesOne Title, Two Incomes
For property investors looking to maximise rental yield while keeping costs efficient, dual key homes are becoming one of the most attractive strategies in the Perth property market.
What is a Dual Key Property?
A dual key property is a single home built on one title that contains two separate, self-contained living spaces.
Typically this includes:
- A main residence (usually 3x2 or 4x2)
- A smaller secondary dwelling (often a 1x1 or studio)
- Separate entrances
- Separate kitchens and bathrooms
- Shared land title
While both dwellings are on the same title, they can be rented separately, providing two income streams from one property.

3. Lower Entry Price Than Duplex
Many investors consider building a duplex, but that typically involves subdivision costs, multiple titles, higher construction costs, and more complex approvals. Dual key homes achieve similar income outcomes but with a simpler structure and lower upfront investment.
4. One Mortgage, One Title
