2026 Budget changes are proposed, not yet legislated
The negative gearing and CGT reforms announced on 12 May 2026 require parliamentary legislation to take effect. Properties held before Budget night are fully grandfathered. Consult a qualified adviser before making any decisions.
The 2026 Federal Budget delivered the most significant shake-up to property investment tax in a generation. For anyone weighing up a new build investment property against an established home right now, the decision looks very different from what it did 12 months ago, and the investment property loan structure you choose needs to reflect that.
This guide breaks down exactly what changed, what it means for new build versus established property investment, and how to choose the right investment property loan for your situation as a Melbourne investor navigating the new landscape.

What the 2026 Budget Actually Did
On Budget night, 12 May 2026, two major reforms to property investment tax were announced. Here’s what they mean without the jargon.
Restricted to new builds from 1 Jul 2027
Under the proposed rules, established property buyers after Budget night would no longer be able to offset rental losses against salary. Losses are quarantined to offset residential property income only. New builds remain fully exempt.
50% discount replaced by indexation + 30% min tax
Under the proposed rules, from 1 Jul 2027, the 50% CGT discount would be replaced by cost-base indexation. New build investors can choose either method at sale, established property investors buying after Budget night cannot.
Existing investors are fully protected.
Any property owned or under a signed contract before 7:30 pm on 12 May 2026 keeps all existing tax treatment forever. Nothing changes for existing portfolios.
New Build Investment Property: The Case For and Against
A new build investment property now carries a clear tax advantage under the new rules. But the numbers don’t always favour it; here’s the honest breakdown.
- ✓ Full negative gearing preserved, rental losses still offset salary income
- ✓ CGT choice at sale under proposed rules: 50% discount or cost-base indexation, whichever wins
- ✓ Maximum depreciation (Div 43 + Div 40) — $8,000–$15,000/yr in early years
- ✓ Government policy now actively incentivises new supply investment
- ✓ Lower maintenance costs in first 5–7 years
- ✗ Settlement 12–24 months away, financial position and rates can change
- ✗ Valuation shortfall risk at completion if prices soften during build
- ✗ Weaker capital growth history vs established, especially high-density apartments
- ✗ Construction delays and builder insolvency are real risks in 2026
- ✗ Land value component is smaller, land drives long-term growth
Established Property Investment, Still Worth It?
The headlines make it sound like established property investment is now off the table. It isn’t. The tax changes are significant, but they don’t eliminate the case, especially for investors who already own property or are targeting capital growth over income minimisation.
- ✓ Stronger capital growth in Melbourne's established suburbs historically
- ✓ Faster settlement (typically 60–90 days, negotiable), no construction risk
- ✓ Quarantined losses still have value if you hold multiple properties
- ✓ CBA forecasts ~3% price softening, potential entry point for long-term holders
- ✓ Grandfathered investors keep all existing tax treatment indefinitely
- ✗ No salary offset for rental losses on purchases after Budget night
- ✗ Less favourable CGT treatment from 1 Jul 2027 under proposed rules (30% minimum rate)
- ✗ After-tax cash flow models need updating, older projections are now incorrect
- ✗ Lock-in effect from existing investors reduces market turnover and listings
- ✗ Higher ongoing maintenance costs vs new builds

How the Budget Changes Your Investment Mortgage Strategy
The tax reforms don’t just change which property you buy; they change how your investment mortgage should be structured. Smart investors are rethinking two key decisions.
Interest-only vs Principal & Interest
For a new build investment property where full negative gearing is retained, an interest-only property investment loan still makes sense, as it maximises deductible interest. It keeps cash flow flexible during the build period. For an established property purchased after Budget night, where rental losses can no longer offset salary income, the advantage of interest-only is reduced. A P&I loan builds equity faster and reduces long-term exposure, often a stronger position when tax minimisation isn’t the primary driver.
LVR and valuation risk on new builds
Most investment home loans cap at 80% LVR without lender mortgage insurance. For off-the-plan new builds, lenders perform a fresh valuation at construction completion, not at your original contract price. If property values soften during a 12–18 month build, that end valuation can come in below the purchase price, reducing how much you can borrow or triggering LMI you didn’t plan for. Understanding your lender’s off-the-plan policy before signing is critical.
Portfolio structure and cross-collateralisation
Investors adding a new build to an existing portfolio should keep debt on each property as standalone security where possible. Linking properties through cross-collateralisation gives lenders oversight of your entire portfolio every time you want to sell, refinance, or restructure one asset. A broker can structure your property investment loans to avoid this from the start.

What Melbourne Investors Are Actually Doing Right Now
Post-Budget, CBA’s analysis projects established property prices roughly 3% lower than they would otherwise have been. But the grandfathering lock-in effect, where existing investors hold rather than sell to preserve their tax treatment, is cushioning prices by reducing listings. Here’s how the Melbourne investors Credit Hub works with are responding.
Holding existing portfolios and reviewing loan rates
Investors who bought before Budget night are protecting their grandfathered tax treatment and focusing on refinancing to a sharper investment property loan rate. With the cash rate currently at 4.35% [confirm at rba.gov.au at publish date], there's meaningful savings available through loan review alone.
Evaluating new build opportunities in Melbourne’s growth corridors
Tarneit, Point Cook, Werribee, and Melton are seeing renewed investor interest in house-and-land packages and townhouse developments. The preserved negative gearing benefit is the driver, but investors are stress-testing the capital growth assumptions, not just the tax benefit.
Running scenario modelling before committing
With CGT changes, quarantined losses, and loan structure all interacting, the investors making the best decisions are those who modelled both options under the new tax rules before signing anything. A broker and accountant working together can do this in one session.
Conclusion
The 2026 Budget didn’t end established property investment, but it fundamentally changed its tax economics for new buyers. Under the proposed rules, new build investment properties would carry a clear tax advantage for investors who need negative gearing to make the cash flow work. Established properties still offer stronger capital growth potential in the right Melbourne locations, and for anyone who held before Budget night, nothing has changed at all. The right answer depends on your income, your existing portfolio, your risk tolerance, and how your investment property loan is structured. One conversation with a Credit Hub specialist broker can make that decision significantly clearer.
Frequently Asked Questions
Can I still negatively gear an established investment property after the 2026 Budget?
If you purchased your established investment property before 7:30 pm on 12 May 2026, nothing changes; your negative gearing entitlements are fully grandfathered. For new purchases of established residential properties made after that date, negative gearing losses would no longer be able to be offset against salary or other personal income from 1 July 2027, under the proposed rules. Instead, those losses are quarantined and can only offset other residential rental income or capital gains when you sell. Under the proposed rules, new build investment properties would remain fully exempt and continue to allow rental losses to offset all income.
How does the 2026 Budget affect the investment property loan I’m about to apply for?
The tax changes don’t directly affect the structure of your investment mortgage in Australia; your loan terms, rates, and features remain the same regardless of whether you buy a new or established property. What changes is the after-tax cash flow model. For an established property bought after Budget night, the loss of full negative gearing means your net annual holding cost may be higher than a pre-Budget projection showed. A broker can remodel your cash flow position under the new rules before you commit to a purchase.
Is a new build investment property always better than an established one after the Budget?
Not automatically. While new builds retain negative gearing and CGT advantages, they come with construction risk, longer settlement timelines, and, in many Melbourne locations, a weaker capital growth track record, particularly for high-density apartments. The tax benefit needs to be weighed against the fundamentals of the specific property. An established home in an inner west suburb like Footscray, Sunshine, or Altona — where land value is strong and rental demand is consistent — may still outperform a new apartment in a growth corridor 40km from the CBD, even accounting for the quarantined gearing.
What is a quarantined rental loss, and how does it work in practice?
Under the proposed rules, a quarantined rental loss would be a rental shortfall on an established investment property (bought after Budget night) that can no longer reduce your taxable salary income. Instead, it’s carried forward and can be used to offset income from other rental properties or to reduce your capital gains tax liability when you sell the property. For investors with multiple properties, quarantined losses still have real value; they’re just used differently. An accountant or financial adviser can model exactly how this affects your overall tax position.
Should I buy before 1 July 2027 to lock in the old rules?
The key cut-off date is actually 12 May 2026, Budget night, not 1 July 2027. If you purchased an established investment property (or had a signed contract) before 7:30 pm on that date, you retain full negative gearing indefinitely. The 1 July 2027 date is when the new rules take effect, not when the cut-off for grandfathering occurred. For new builds, there is no cut-off date — negative gearing and CGT concessions remain available regardless of when you buy.
