Location used to be the first call. Not any more. The 12 May 2026 federal budget, now law, quarantined negative gearing on established purchases while new builds keep their full deductions, and APRA's debt-to-income caps exempt new builds too — so the first decision when buying an investment property in Australia is no longer where, it's what: brand new, or established. This guide runs the full sequence in the order the decisions arrive: the tax fork, the deposit, the borrowing assessment, the market numbers, then the settlement checklist.
One thing before the steps: the cycle, because it sets your negotiating position. The RBA cash rate sits at 4.35% after hikes in February, March and May 2026 and a hold in June, with the next decision due on Tuesday 11 August 2026. Rising rates thin the crowd. Auction clearance rates are running in the low 40s and sellers are negotiable, yet investors haven't left the market, because the income side of the ledger is strong: rents rose 5.9% over the year to June 2026 and vacancy sits at 1.6% (Cotality). Fewer bidders, stronger rents. For a prepared buyer, that combination is an opening, not a warning.
Why is new-build vs established now the first decision?
Because the tax system and the credit system now treat them differently, and both push in the same direction.
The tax change first. Buy an established property after 7:30pm AEST on 12 May 2026 and, from 1 July 2027, its rental losses can no longer offset your salary. The losses don't disappear. They're quarantined: still deductible against your residential property income, including capital gains, and carried forward until that income arrives. Buy or build a new dwelling and negative gearing keeps working the way it did before the budget: the loss comes straight off your wage income at your marginal rate, in the same financial year you incur it. Anything you owned before budget night is grandfathered for negative gearing purposes.
Now the credit change. Since 1 February 2026, APRA has capped the share of new lending, owner-occupier and investor alike, that lenders can write at a debt-to-income ratio of six times or higher: no more than 20% of new loans per lender. It is the first time these caps have been switched on in Australia. Construction loans and new builds are exempt.
Think of the DTI cap as a capacity limit on a nightclub. Only so many high-DTI borrowers get through the door each quarter, and new builds skip the queue entirely.
Chain it through. Treasury pointed the tax incentive at new housing stock; APRA pointed the credit supply the same way. For a high-income professional already carrying a home loan, an established investment property is now harder to finance and less rewarding to hold, while a new build keeps the deductions and sidesteps the cap. The practical move: price both paths with your accountant before you inspect a single property, and factor in the capital gains change while you're there. From 1 July 2027 the 50% CGT discount is replaced by cost-base indexation plus a 30% minimum tax rate on gains; gains accrued before that date keep the discount.
New builds carry one more edge worth naming: the strongest depreciation schedules. Second-hand plant and equipment hasn't been deductible since 2017, so an established unit's paper deductions are thin, while a brand-new build can throw off five figures of deductions in year one.
| New build | Established (bought after 12 May 2026) | |
|---|---|---|
| Negative gearing against salary | Kept in full | Ends 1 July 2027; losses quarantined against property income and carried forward |
| APRA DTI cap (6x and above) | Exempt | Counts toward the 20% limit |
| Depreciation | Full capital works plus new fittings | Thin; second-hand fittings non-deductible since 2017 |
| Foreign buyer competition | Open to foreign buyers | Ban on existing homes extended to mid-2029 |
That last row cuts the other way. The foreign-buyer ban funnels overseas demand into new stock, so expect more competition for off-the-plan product and less for the weatherboard three-bedder in an established street. Neither column wins outright, and established property still suits some buyers: better land content, proven streets, no builder risk. The point is that you now choose deliberately, not by default.
How much deposit do you need? Less than you were told
You've probably budgeted for a 20% deposit plus costs, because that's the figure the industry quoted for decades. That rule got renegotiated. Under specialist lending policies available through Wity, any borrower, investors included, can borrow to 85% LVR with no LMI: a 15% deposit. On an $800,000 loan, that's $12,000–$16,000 you don't pay, and don't pay interest on for 30 years either. Allied health, nurses, midwives and senior professionals go to 90%. Doctors and dentists, 95%. LMI waivers on investment lending are rare in the mainstream market, which is exactly why most first-time investors over-save and under-buy.
Budget for the on-top costs while you're at it. Stamp duty gets no first-home concession on an investment purchase in most states, and legals, building and pest, and a cash buffer for the first vacant fortnight all sit outside the loan. On a $760,000 purchase, those extras typically run well into five figures, so price them before you set your ceiling, not after you've signed.
Already own your home? Your deposit may not need to be cash at all. Releasing equity from your existing property can cover the deposit and purchase costs while your savings stay in the offset. If you take that route, keep the two loans standalone rather than cross-collateralised, so one property's troubles can't spill onto the other and you keep control of any future sale proceeds. High earners with a mortgage and surplus cash flow can layer a debt recycling strategy over the top, steadily converting non-deductible home loan debt into deductible investment debt.
What will a lender actually let you borrow?
Three mechanisms decide it, and none of them appear on the front page of a bank calculator.
The buffer. APRA held its 3% serviceability buffer at the 28 May 2026 review, so whatever rate you're offered, the lender assesses your repayments at that rate plus three percentage points. In a rising cycle the buffer stings, which is precisely why the borrowers still standing at auction face so little competition.
The rent haircut. Lenders don't credit your projected rent in full. Most count 80 cents in each rental dollar to allow for vacancy and costs, some shade holiday lets harder again, and we've watched that shading alone swing a borrowing assessment by more than $60,000.
The DTI count. Add your existing home loan to the proposed investment loan and divide by gross income. A household on $220,000 carrying a $750,000 home loan reaches the six-times line with just $570,000 of new borrowing, and once a lender's high-DTI quota for the quarter is full, a decline can land on numbers that would have sailed through in January. A new build steps around the count entirely, which for leveraged professionals is often the difference between approved and parked.
One caution while you compare: read any advertised rate alongside its comparison rate and the date it was published. A rate table printed in early July 2026 can be stale by the 11 August RBA meeting, and the cheapest headline rate with the wrong structure costs more than a fair rate with the right one.
These three interact differently at each of 45+ lenders. That's why the Wity Borrowing Power Assessment models your capacity across the whole panel rather than one bank's calculator: two lenders can land six figures apart on identical payslips, because each shades rent, treats bonuses and applies the DTI rules its own way. You can see how that modelling feeds a full loan structure when you start the Wity questionnaire.
Which city do the mid-2026 numbers favour?
Cotality's June 2026 Home Value Index shows one national figure hiding five different markets:
| Market | Median value | Change |
|---|---|---|
| Perth | $1,047,000 | +23.9% year |
| Brisbane | $1,118,000 | +17.4% year |
| Adelaide | $946,000 | +11.6% year |
| Sydney | $1,266,000 | −3.2% quarter |
| Melbourne | $808,000 | −0.9% year |
| National | $937,722 | −0.4% month (June) |
Read it as a yield map, not a leaderboard. Perth and Brisbane have momentum, but a 20%-plus run compresses rental yields: the rent hasn't kept pace with the price. Melbourne going backwards means sharper entry yields and vendors who return calls, at the cost of near-term momentum. Sydney's quarterly dip plus a $1.266M median makes the DTI cap bind hardest there for established stock. And the national reading fell 0.4% in June alone, so the heat is coming out at the very moment rents are still climbing 5.9% with vacancy at 1.6%.
The upshot for a first purchase: chase rental depth, not postcode loyalty. A growth-corridor new build in Ripley or Logan on Brisbane's fringe, or a townhouse in Melbourne's north with a queue at the open home, can out-earn a prestige suburb you picked because you know it.
Same buyer, two paths: what the choice costs in dollars
Meera, 34, is a senior project engineer in Brisbane on $185,000. She has $130,000 saved and is weighing two options at around $760,000: an established unit in Annerley or a new townhouse in Ripley, out in the Ipswich growth corridor. Through Wity she puts down 15% ($114,000), borrows $646,000 at 85% LVR and pays no LMI, keeping roughly $9,000–$13,000 that most lenders would have added to her loan. On either property, her interest and holding costs exceed the rent by about $11,000 a year.
Path A: the Annerley unit. Until 30 June 2027, the $11,000 loss offsets her salary and returns about $4,290 a year at her 39% marginal rate (including the Medicare levy). From 1 July 2027, that stops. The losses bank up quietly and only pay off against future rental profits or the capital gain when she sells. Depreciation adds little, because the fittings are second-hand.
Path B: the Ripley townhouse. The same $11,000 cash loss keeps offsetting her salary with no end date, and a quantity surveyor's schedule adds roughly $12,000 of depreciation in year one. Total deductions near $23,000, worth about $8,970 back at tax time. Her loan also sits outside APRA's high-DTI count, which barely matters at her income today but keeps the runway clear for property number two.
The gap: roughly $9,000 a year in after-tax cash flow from 1 July 2027, before any difference in capital growth.
Based on typical scenarios. Individual outcomes vary.
Ready to move? The seven steps in order
- Choose the asset type first. New build or established, decided with your accountant on your marginal rate and horizon, before your first inspection.
- Set the deposit strategy. Cash at 15% with no LMI, or equity released from your home with the securities kept standalone.
- Model borrowing power across lenders, with the 3% buffer, rent shading and DTI count applied the way each lender actually applies them.
- Get pre-approval before you shortlist suburbs. In a low-clearance market, the approved buyer sets the terms.
- Pick the market on rental depth. Vacancy under 2% and a queue at the open home beat postcode sentiment.
- Negotiate like the cycle is on your side, because it is: clearance in the low 40s means the vendor's agent needs you more than you need them.
- Structure at settlement. Offset account, repayment type, ownership split, and order the depreciation schedule in week one, not at tax time.
