New vs Established Investment Property in 2026: Why the Tax Rules Now Favour New Builds
From 1 July 2027, two investors paying the same price for the same rent can face very different tax bills, simply because one dwelling is new.
October 2025 shows a mixed picture. The national average build price per m² eased to $2,387.33 per m², down -7.51% from $2,581.17 per m² in July. At a property type level, Dual Occupancy recorded the strongest average at $3,120.87 per m² and rose +7.27% on July, while Co-Living and House and Land were broadly flat to slightly lower. Variations by state were material, with VIC Dual Occupancy rising sharply and WA Co-Living also lifting.

• Headline movement: October’s national average slipped relative to July. This reflects a mix shift and some softer categories.
• Product dispersion: Dual Occupancy, Dual Key and Duplex showed firm gains nationally, consistent with investor demand for multi-income formats.
• State signals: VIC saw the largest product shifts, with strong gains in Dual Occupancy and Duplex. WA delivered solid gains in Co-Living and Dual Key. QLD was mixed.
• Data completeness: New states have been added this quarter. Where July baselines were not present, comparisons are omitted. Metro and regional splits were not available in the data provided.
• Yield oriented designs: Dual Occupancy, Dual Key and Duplex offer attractive per m² profiles relative to achievable rents.
• Conservative budgeting: Lock in pricing where feasible, and allow for specification and compliance changes in regulated formats like SDA.
• State selection: Use state specific averages rather than national benchmarks when assessing feasibility.
• Next steps: Provide a Metro or Regional flag to incorporate location tiering and sharpen pricing guidance.
October 2025 confirms that headline averages have eased while several high utility formats have strengthened. Dual Occupancy, Dual Key and Duplex posted gains and remain attractive where design efficiency and builder capacity are sound. State outcomes diverged, so portfolio construction should prioritise state and product selection over a single national benchmark.
