According to realestate.com.au, new modelling has found Labor's negative gearing reforms could cost Sydney tenants up to $24,700 extra per year in rent, with the magnitude of the increase varying significantly depending on which part of the city a renter calls home. That figure — nearly $476 per week in additional rent burden — has quickly sharpened the political debate around a policy that was originally framed as a measure to improve housing affordability for aspiring owners.
What the Modelling Actually Shows
The modelling, reported by realestate.com.au, finds that the rent cost impact is not uniform across Sydney. Some areas of the city face materially worse outcomes than others, driven by the existing concentration of negatively geared investment properties in those submarkets. The $24,700 figure represents the upper bound of annual additional cost, applying to tenants in the most affected parts of the city.
This matters because it inverts the core affordability argument behind the reforms. The policy rationale — that curbing negative gearing would free up more properties for owner-occupiers to purchase, easing prices — assumes sufficient new supply enters the market to absorb displaced renters. The modelling suggests that assumption is not holding. When investors exit or decline to purchase existing stock, rental vacancy tightens, and landlords who remain can command higher rents. The net effect, at least in the short-to-medium term, is that renters pay more before the intended price correction for buyers materialises, if it materialises at all.
The Investor Supply Mechanism Driving Rents Higher
Negative gearing allows property investors to deduct rental losses against other income, reducing their tax liability. When that deduction is curtailed or eliminated, the after-tax return on investment property deteriorates. For investors holding property in high-yield, low-growth submarkets — the type often rented by middle- and lower-income Sydneysiders — the financial case weakens most rapidly. The modelling's rent impact reflects what happens when those investors sell up or decline to buy in the first place: the rental pool shrinks, vacancy falls, and landlords who remain face less competition, giving them greater pricing power.
Sydney's rental market was already under structural strain before this policy debate intensified. The city's clearance rate has come under pressure — REAStats data from mid-August 2026 shows Sydney's auction clearance rate sitting at 54%, with an inner west property selling for $3.5 million post-auction — $300,000 below its February 2026 peak. A softening sales market might ordinarily attract more investors back to pick up discounted stock. But if negative gearing concessions are simultaneously being wound back, the incentive to re-enter evaporates. You get a market where prices are easing for buyers but rental supply is not recovering — the worst combination for tenants.
For investors assessing whether to hold, sell, or buy in Sydney right now, the policy direction adds a layer of uncertainty that is difficult to price. Those considering purchasing existing residential stock as a long-term rental investment need to model scenarios where negative gearing deductions are reduced or eliminated entirely. The tax implications interact directly with loan structure, holding period, and eventual capital gains treatment. The APF guide on Capital Gains Tax on Australian Property outlines how these tax levers interact and what investors need to account for before committing capital.
For broader context on how Australian property investment stacks up against global alternatives under changing tax settings, the Australian Property Prices vs the World guide provides useful comparative framing. Domestically, the direction of reform is clear — the question is how fast it moves and whether transitional arrangements soften the impact on existing investors and, critically, their tenants.
Auction Market Context and the Negative Gearing Feedback Loop
Sydney's auction market is already absorbing multiple headwinds simultaneously. The 54% clearance rate reported by REAStats indicates a market where buyers hold more negotiating power than they did six months ago. Properties selling below their prior peaks — as the inner west example illustrates — reinforces that dynamic. Yet this does not necessarily benefit renters, whose fortunes are tied to investor activity rather than buyer competition at the hammer. For a comprehensive overview of how to approach buying in this environment, see the APF guide on How to Buy at Property Auction in Australia.
The feedback loop between negative gearing reform and auction dynamics is worth mapping clearly. If investors sell existing rentals in response to reduced tax incentives, those properties typically transact at auction. More investor-owned properties hitting the market should, in theory, provide additional buying opportunities for owner-occupiers. That increased supply at auction may exert modest downward pressure on prices — which is part of the policy intent. But the gap between a property being sold by an investor and being re-occupied as a rental is a period of reduced rental supply. If the new owner-occupier moves in, that property exits the rental pool permanently. The net effect on rental vacancy is negative, and the modelled rent increase is the consequence.
