Off-the-plan apartment sales hit $44 billion across Australia in the past 12 months, and more than half of all new apartment buyers in 2025–26 chose to buy before construction finished. That figure alone tells you the market has moved beyond niche. But signing a contract on a building that doesn’t exist yet carries a different set of trade-offs than buying something you can walk through, and the research that exists on this topic is worth unpacking before you decide whether it’s the right path for your situation.

Those headline figures only tell part of the story. The same research shows that buyers using dedicated apartment platforms are 34% more likely to proceed to enquiry within 30 days, which hints at how much the off-the-plan market relies on digital discovery rather than physical inspection. At the same time, construction costs have risen roughly 35% since 2020, and the number of companies entering external administration in 2024–25 hit a record high, with construction the single worst-affected industry. That gap between the glossy marketing and the ground-level reality is where most of the risk sits. Here’s what you actually need to know.
Four Things That Matter Most Before You Sign
Buying an apartment before it’s built means you’re working from plans, a finishes schedule, and a display suite rather than a finished home. The contract is typically 80 to 150 pages, and it’s written to favour the developer. The first important term to understand is off-the-plan: purchasing a property that hasn’t been built yet, with settlement occurring after the building receives its occupation certificate, usually 12 to 36 months after you exchange contracts.
What tends to make sense here is treating the decision as two separate questions: does the financial structure work for you, and can you tolerate the uncertainty of the construction phase? The four cards above trace the main arguments on both sides. First home buyers in states with strong stamp duty concessions and high-income investors who can use depreciation deductions tend to come out ahead. Buyers who need certainty on timing, final cost, and property condition are usually better served by established stock. There’s no universal answer, and the research that exists on which Australian buyer profile you match can help you work out which side of the ledger you sit on.
What the Full Cost Picture Actually Looks Like
The purchase price is never the only number that matters. Off-the-plan transactions involve a different cost structure than established property purchases, and the differences can shift the total outlay by tens of thousands of dollars. The table below lays out the key cost items side by side.

| Cost Item | Off-the-Plan Apartment | Established Property |
|---|---|---|
| Deposit at exchange | 10% (held in trust until settlement) | 10% (released at settlement) |
| Stamp duty calculation | Dutiable value at exchange — land value only | Full market value at settlement |
| Legal / conveyancing fees | $800 – $1,500 (longer contract review) | $300 – $500 |
| Pre-settlement inspection | $120 – $350 (independent building inspector) | Normally included in cooling-off period |
| Capital cost of waiting | $15,000 – $45,000 over 12–24 months (opportunity cost) | None — immediate occupancy or rental income |
| Valuation risk at settlement | High — gap can require $48,000+ extra cash | Low — value is known at contract |
The biggest single cost trap in off-the-plan buying is the valuation gap. Here’s a real scenario from the research: you sign a contract at $900,000 and pay a 10% deposit ($90,000). You expect an 80% LVR loan of $720,000. At settlement, the lender values the property at $840,000. Your loan drops to $672,000 (80% of $840,000). The shortfall between what you owe and what the bank will lend is $48,000 — money you need to find from savings or by renegotiating with the developer.
What I’d add is that the opportunity cost of waiting through a 12-to-36-month construction period is rarely factored into the glossy comparisons. The research estimates that cost at $15,000 to $45,000 depending on financing arrangements and what else you could have done with the capital. That’s real money, and it should be weighed against the stamp duty savings and depreciation benefits on the other side. If you’re an investor, the cash flow picture matters too: on a $780,000 off-the-plan apartment with an 80% LVR loan at 6.35%, the pre-tax annual cash flow is negative $11,984, even with $770 per week in gross rent. The depreciation deductions help, but they don’t turn negative into positive in the early years.
Where Off-Plan Buyers Most Often Get Stuck
Developer insolvency during construction
In the 2024–25 financial year, more than 14,700 companies entered external administration across Australia, and construction was the single largest industry affected. If your developer goes under mid-build, your deposit sitting in a trust account should be protected, but you lose the property, the time you waited, and any market growth that happened during construction. The research recommends checking the developer’s completed projects, looking up their iCIRT rating in NSW (three gold stars or higher), and searching for tribunal decisions at NCAT, VCAT, or QCAT that mention defects or class actions. That homework takes a few hours and can save you from a multi-year loss.
Valuation falling short of the contract price
The example above — $48,000 shortfall on a $900,000 contract — isn’t unusual. Lenders use current market conditions at settlement, not the price you agreed to 18 months earlier. The research suggests modelling a 5–10% valuation drop before you sign, and keeping a cash buffer above your deposit. If you can’t cover the gap, you either renegotiate with the developer (who has no obligation to budge), arrange additional finance, or walk away and lose your deposit. This risk is highest in oversupplied markets where new apartment stock is concentrated in a single postcode.
Borrowing capacity changes during the wait
Pre-approval is a snapshot based on current policy and doesn’t guarantee funding at settlement 18 months later. The ABS March 2026 data shows unemployment at 4.3% and underemployment at 5.9%, and lenders reassess your borrowing capacity at settlement. A car loan, a credit card limit increase, or a change in childcare costs can reduce serviceability even if your income went up. The research recommends reviewing your borrowing capacity every 6 to 12 months during construction, keeping your tax returns and payslips current, and reducing unused credit card limits. It’s administrative work, but it’s the difference between settlement and scrambling.
Quality and defects that don’t match the plans
The common defect categories are consistent across state tribunals: water ingress, poor acoustic separation, defective tiling, and non-compliant fire elements. Appliances and inclusions sometimes differ from what was in the finishes schedule, and strata issues in common areas can surface after settlement. The research is clear that the pre-settlement inspection is your last real moment of leverage. Budget $120 to $350 for an independent building inspector, and use their report to force the developer to fix issues before you settle. The defect liability period in most states runs 90 days to 12 months after practical completion, but getting things fixed after settlement is harder than before you hand over the final payment.
How the Off-Plan Process Works From Start to Finish
The process has six clear stages, and each one asks something different from you. Knowing where the risk sits at each step is what keeps settlement from turning into a last-minute scramble.
- 1Research and shortlist — before any money changes handsLook at the developer’s finished projects and walk through a building they’ve already delivered. Check online reviews, tribunal decisions, and news coverage mentioning defects or class actions. In NSW, check the developer’s iCIRT rating — only builders with three gold stars or higher appear on the public registry. A clean track record is worth a small price premium.
- 2Expression of interest and holding depositRegister your interest with the developer or selling agent, often with a small holding deposit of $1,000 to $5,000. This is usually refundable and holds the property off-market while your solicitor reviews the contract.
- 3Contract review and exchange — the stage that matters mostYour solicitor or conveyancer needs to go through the sunset clause, variation clause, deposit arrangements, defect rectification period, disclosure statement, and draft owners corporation budget. Expect to pay $800 to $1,500 for an off-the-plan review — more than a standard purchase — because the document is longer and trickier. Once you exchange, you pay the balance of the deposit into a statutory trust account. If you need a second opinion on specific contract terms, services like JustAnswer Real Estate Law can connect you with a property lawyer for a targeted question without the full retainer.
- 4Construction period — wait and monitorYou’re not making mortgage repayments yet because you haven’t settled. What you need to do: keep your pre-approval current (most lapse every three months), hold your job and income steady, avoid new debts or large unexplained deposits into your accounts, and monitor developer updates and any changes to the sunset date. The impact of interest rate changes during this period can affect your borrowing capacity at settlement, so it’s worth running your numbers again every six months.
- 5Pre-settlement inspection — your last moment of leverageBefore settlement, inspect the property and note any defects or anything that doesn’t match the finishes schedule. Bring an independent building inspector and budget $120 to $350 depending on the size. Their report is what your solicitor uses to force the developer to fix things or to hold back funds before you settle. Don’t skip this step.
- 6Settlement and move-inWhen the building gets its occupation certificate, your lender orders a formal valuation, your finance is confirmed, and you settle — paying the balance and getting the keys. Off-the-plan settlement usually runs 14 to 21 days from notification, faster than a standard established-property settlement.
What the 2026 Federal Budget means for off-the-plan buyers
The 12 May 2026 Federal Budget changed the tax rules for property investment effective 1 July 2027, and it made off-the-plan purchases significantly more attractive for investors. Under the new rules, negative gearing will apply only to new residential properties — established property owners can still offset losses against other rental income but not against wages or personal income. The 50% CGT discount for investments held over 12 months will be replaced for established property by an inflation-based calculation and a minimum 30% tax on gains. New homes, including off-the-plan apartments and townhouses, are exempt from both changes. The ATO treats the acquisition date for off-the-plan purchases as the contract signing date, meaning the 12-month ownership period for the CGT discount is usually satisfied before settlement. That window is open now, but it won’t last forever.

Why the 2026 Budget Shift Changed the Rules for Investors
The May 2026 Budget didn’t just tweak the tax settings — it created a structural advantage for new builds that didn’t exist before. Investors who buy off-the-plan now lock in full negative gearing and the 50% CGT discount, while established property investors lose both benefits from July 2027. That changes the calculation for anyone comparing new versus existing stock. The research shows that off-the-plan apartments delivered 3.4% median annual capital growth from 2016 to 2025, compared to 5.8% for established houses, and established units outperformed new-build units by 1.2% per annum. The tax tail doesn’t wag the dog, but it can close that gap significantly for investors in the top tax brackets. For first home buyers, the stamp duty savings and grant eligibility remain the stronger pull. The right answer depends on your timeline, your tax situation, and your tolerance for the construction-phase risks this article has laid out.
