Key Facts
- Dual Occupancy Strategies refers to having two separate, self-contained homes on a single residential block — such as a duplex, granny flat, or dual-key dwelling.
- It’s a strategy designed to boost rental income, increase site value, and create flexible living arrangements for families.
- Feasibility depends on zoning rules, council approvals, block size, and local planning controls.
- Ideal for investors, downsizers, and owner-occupiers who want income from their land.
- Flint helps assess finance options, council pathways, and project viability before committing.
What Is Dual Occupancy?
Dual occupancy involves owning or building two separate dwellings on one title or block. These may be attached or detached, depending on planning rules and block layout.
Common dual occupancy types include:
- Duplexes – two attached homes, each with private entrances
- Granny flats – secondary dwellings typically positioned behind the main home
- Dual-key homes – one main doorway leading to two distinct living areas
Each option can be used for rental income, multi-generational living, or, in some cases, sold separately after subdivision where permitted.
Benefits of Dual Occupancy
Why Investors and Homeowners Love It:
- Generate two rental incomes from one land asset
- Live in one and rent out the other to reduce mortgage pressure
- Increase overall property value through development uplift
- Support multi-generational families with independent living areas
- Access strong depreciation benefits for new construction
What to Watch Out For
Potential Challenges:
- Zoning restrictions — many suburbs have strict rules on dual occupancy
- Council approvals — DA or CDC needed depending on state and lot size
- Development costs — subdivision, utility upgrades and build expenses can add up
- Title structure — single vs dual title affects finance and future sale options
- More management — two tenants means double the administration
Finance Considerations
- Construction loans may be required for duplex or dual-key developments
- Lenders may assess value based on build cost, comparable sales, or rental yield
- Different banks have varying policies for dual-key and non-standard properties
- Flint works with lenders experienced in dual occupancy, subdivision, and small-scale development
