Gross Yield Calculation
Gross yield = Annual rental income ÷ Total asset value (or total development cost)
Yield on total development cost (land + construction + all costs): • Fairfield duplex: $55,120–$62,400 ÷ $1,600,000 = 3.4–3.9% • Liverpool duplex: $58,240–$66,560 ÷ $1,800,000 = 3.2–3.7%
Yield on construction cost only (when you already own the land): • Fairfield: $55,120–$62,400 ÷ $800,000 = 6.9–7.8% • Liverpool: $58,240–$66,560 ÷ $900,000 = 6.5–7.4%
The yield on construction cost (when you own the land) is the most relevant comparison for homeowners doing a duplex development on their existing block. At 6.5–7.8%, this significantly outperforms buying an investment property (typical gross yield for established houses in Western Sydney: 2.8–3.5%).
Improving Your Rental Yield
Strategies that increase duplex rental returns:
1. Quality finishes attract quality tenants. Stone benchtops, modern tapware, and good flooring reduce vacancy periods and justify higher rents. The additional construction cost of $20,000–$30,000 can increase rent by $40–$60/week — a return of 7–10% on the upgrade cost.
2. Separate utilities. Each dwelling should have its own electricity meter, gas meter, and preferably water meter. Tenants pay their own utilities — no disputes over split billing.
3. Air conditioning. Ducted or split system air conditioning is expected in Western Sydney. Homes without AC rent for $30–$50/week less.
4. Outdoor living. An alfresco area or covered patio is standard for family homes in Western Sydney. It extends the living space and adds rental appeal.
5. Storage. A garage with internal access and some storage space adds value. Western Sydney families have cars and belongings — garage space matters.
