You've seen the headline. Sydney house prices could fall. The question most people quietly ask is: does that mean I should wait, or does it mean I should move?
The honest answer is: it depends on your structure, your time horizon, and what type of property you're looking at. Here's what the data actually says and what it means for investors and SMSF buyers.
What the Forecasts Actually Say
Domain's FY27 forecast tips Sydney house prices to fall between 3% and 7% over 2026-27, while Perth, Adelaide, and Brisbane are expected to rise, in some cases to record highs.
Forecasts are not uniform. ANZ Research takes a more moderate view, forecasting Sydney house prices to fall 0.7% in calendar 2026, with a recovery to 2.6% growth pencilled in for 2027. At the optimistic end, CBA is calling a +2.0% gain for Sydney, while Westpac sits at -3.0%. In other words, the major institutions genuinely disagree, and the range is wide.
Two things are driving the softer outlook. Three rate hikes in the first half of 2026 changed conditions, and the federal budget's decision to remove negative gearing from established properties and adjust the CGT discount introduced a structural shift on top of the cyclical one. At the time Domain finalised its forecast, money markets priced approximately even odds of a further rate hike in the second half of 2026, which the report identified as the principal downside risk, with each additional 25 basis points removing a further approximately 2.5% of borrowing capacity.
Units are holding up better than houses. Sydney and Melbourne units are tipped to fall only 1% to 3%, well short of the falls expected for houses. Sydney's lower-quartile values have been rising while the upper quartile has fallen for five consecutive months, a genuine two-speed pattern within the city.
The Policy Shift That Changes the Maths for Established Properties
The 2026-27 Federal Budget introduced two significant changes that affect how investment property is taxed. Both are now law, per the ATO.
Negative gearing: The government announced it would reform negative gearing and CGT arrangements as part of the 2026-27 Federal Budget, and these measures are now law. Negative gearing for established residential properties is abolished from 1 July 2027 for purchases made after Budget night, with new builds exempt. After that date, rental losses on existing residential investment properties bought after 7:30 pm on 12 May 2026 will be quarantined so they can only be offset against other residential property income, including capital gains.
CGT discount: From 1 July 2027, the existing 50% CGT discount for individuals, trusts, and partnerships will be replaced with indexation and a 30% minimum tax rate. Properties held at the announcement date will be exempt from the negative gearing changes, and the CGT reforms will only apply to gains that accrue after 1 July 2027.
Importantly, at this stage it is not expected that the CGT discount for superannuation funds will be changed. This distinction matters for SMSF investors specifically.
What does this mean in practice? Eligible new builds will remain exempt, with investors still able to access both negative gearing and the 50% CGT discount. For investors who rely on negative gearing against personal income, the calculus for established properties purchased from here has shifted materially. A licensed tax adviser is the right person to work through the specifics with you.
The SMSF Angle: How the Numbers Sit Inside Super
For buyers using an SMSF with a Limited Recourse Borrowing Arrangement (LRBA), the policy environment looks different. Rental income inside super is taxed at 15% in accumulation phase, and 0% in pension phase up to the Transfer Balance Cap. The CGT discount change for individuals does not currently apply to super funds.
The LRBA structure itself requires attention before acting:
- Residential SMSF loans are typically capped at an LVR of 70% to 80%, meaning a deposit of 20% to 30% of the property price.
- Most lenders require a minimum SMSF balance of $250,000 to $300,000 before considering an LRBA application, with some requiring $350,000 or more.
- The property's legal title is held by a bare trustee during the loan period. If the fund defaults, the lender's recourse is limited to that one property and cannot extend to the rest of the fund's assets.
- A residential property held in your SMSF cannot be lived in or rented by you, your relatives, or any related party. It must be let at market rent to an unrelated tenant.
For related-party LRBAs, the ATO's Practical Compliance Guideline PCG 2016/5 sets safe harbour interest rates. For 2025-26, the safe harbour rate for LRBAs used to acquire real property is 8.95%, down from 9.35% in 2024-25. These rates are based on RBA indicator lending rates and are updated each financial year. Always check the current rate at ato.gov.au before structuring a related-party loan.
Note also: a proposed super tax (Division 296) has sparked political debate, with some calling for a ban on SMSF borrowing in return for supporting the legislation, placing future LRBA arrangements under ongoing scrutiny. The rules as they currently stand permit SMSF borrowing through LRBAs, but this is a space worth monitoring with an SMSF specialist accountant.
A Worked Example: Accumulation Phase SMSF, Sydney Unit
Consider an illustrative scenario. An SMSF in accumulation phase purchases a new Sydney unit at $850,000. The fund puts down a 25% deposit ($212,500) plus costs. The property is let to an unrelated tenant.
- Rental income of, say, $42,000 per year is taxed at 15% inside the fund (approximately $6,300 in tax), compared with a marginal rate of 37-47% if held personally.
- Because this is a new build, negative gearing treatment (where applicable) and the CGT concession available to super funds are not affected by the 2026-27 budget changes.
- If the fund transitions to pension phase before selling, gains accrued in pension phase up to the Transfer Balance Cap face 0% CGT.
These figures are illustrative only. Actual outcomes depend on the fund's specific cashflows, loan terms, fund balance, and member circumstances. This is general information, not a projection of returns.
What the example shows is that the tax environment inside super, for new builds specifically, looks structurally different to holding established investment property personally after 12 May 2026.
What to Do Next
A falling price environment in Sydney raises real questions worth working through properly:
Get clear on your structure first. The decision between buying personally, in a trust, or inside an SMSF has different tax and borrowing implications, especially given the budget changes. Speak with an SMSF specialist accountant and a licensed financial adviser before settling on a structure.
Understand what the new build distinction means for you. A new build is defined as a residential property that genuinely adds to housing stock. Not every off-the-plan property qualifies, and the definition matters for both negative gearing and CGT treatment. A tax adviser can confirm whether a specific property meets the criteria.
