According to realestate.com.au, new analysis by Ray White — Australia's largest real estate network — has found that if property prices remain unchanged, rents would need to surge about 30 per cent to make investing attractive again. Alternatively, to reach the higher self-funding threshold, even if rents climbed 20 per cent, property prices would need to fall about 27 per cent. That is not a forecast of what will happen. It is a calculation of what must happen for investors to achieve the same after-tax position they held before the policy changed. Either outcome carries severe consequences for renters, buyers, or both.
What Ray White's Modelling Actually Shows
Ray White's analysis frames the negative gearing reform impact in stark arithmetic terms. Under the previous system, an investor could offset rental losses against other income — typically wages — reducing their taxable income and effectively receiving a tax subsidy on cash flow shortfalls. The new rules restrict or remove that offset for established residential properties, depending on the structure of the reform. Without the tax subsidy, the same property at the same price generates a materially worse after-tax return. Ray White's modelling — as reported by realestate.com.au — calculates that restoring equivalent after-tax returns requires either a 27 per cent fall in purchase prices or a 30 per cent rise in rents.

The significance of the 27 per cent figure lies in its scale. A correction of that magnitude would represent one of the deepest sustained price falls in modern Australian property history. The 30 per cent rent rise scenario would impose enormous cost-of-living pressure on Australian households who rent. Neither outcome is benign. Both are the direct arithmetic consequence of removing a tax concession that was, for decades, embedded into investor pricing models.
For investors already holding established residential properties, the modelling clarifies why many are reassessing their portfolios. The after-tax cash flow profile has shifted materially. An investor who purchased a property on the expectation of ongoing tax offsets must now recalculate holding costs, yield requirements, and capital growth assumptions. For those with high loan-to-value ratios and thin rental yields, the reform represents a structural change to investment viability — not a temporary headwind. For a detailed breakdown of how Australian property tax rules interact with investment returns, the APF tax guide is essential reading.
The Rental Yield Squeeze at the Heart of the Problem
The Ray White analysis exposes a fundamental tension in Australian residential property investment: yields have been structurally suppressed for two decades by capital growth expectations and the tax subsidy of negative gearing. When the subsidy is removed, the underlying yield — what a property actually earns as a percentage of its purchase price — must do more work to justify the investment. As our guide to Understanding Rental Yield in Australian Property explains, gross yields across most Australian capital cities have been suppressed for years, with net yields (after costs) often significantly lower. At those levels, negative gearing was not a fringe benefit — it was load-bearing for investment viability.
The mechanism is straightforward. A property generating a low gross yield in a city where purchase prices are high creates significant annual cash shortfalls after accounting for mortgage interest, rates, insurance, property management fees, and maintenance. Under the old rules, those shortfalls were partially recovered via reduced personal income tax. Remove that recovery mechanism and the investor must either accept a lower return — which many will not — or demand a higher yield. Higher yield comes from lower prices, higher rents, or both. Ray White's 27/30 formulation is simply that maths made explicit.
For landlords currently managing established investment properties, the practical implication is immediate. If rents cannot be raised quickly enough to offset the lost tax benefit — and in many jurisdictions, tenancy laws constrain the pace and frequency of rent increases — cash flow turns sharply negative without the tax offset. Some investors will sell. That selling pressure, if it materialises at scale, introduces a potential feedback loop: rising supply of investment properties for sale could exert downward pressure on prices — which is the mechanism behind the 27 per cent figure — but falling prices also damage equity positions and serviceability ratios for those who borrowed against expected valuations.
When negative gearing is removed from the investment equation, established residential property yields in most Australian capital cities are insufficient to sustain investor returns at current price levels — forcing the market to resolve the gap through either price adjustment, rent adjustment, or a sustained exit of capital from the asset class.
Negative gearing is not simply a tax break — it has functioned as a pricing input for Australian residential property for decades. Investors factored the after-tax cost of holding a loss-making property into their willingness to pay at auction, which in turn elevated prices across the market. Owner-occupiers, who cannot negatively gear, competed against investors who could. The result was that the concession was, in effect, capitalised into property values over time. Reforming it does not merely adjust investor returns going forward — it calls into question the pricing assumptions baked into every property purchased under the old regime. For a foundational explanation of how gearing strategies work, see the APF guide on Property Depreciation Schedules, which works in tandem with negative gearing to shape after-tax returns.
This is why Ray White's two-scenario model — 27 per cent price fall or 30 per cent rent rise — represents a genuine market stress test rather than an extreme outlier forecast. The concession removal does not leave the market where it was. It demands an adjustment. The only questions are who bears the cost, how quickly the adjustment occurs, and whether policy settings (such as supply-side incentives for
