I have watched every Sydney cycle since the late 1980s. Each downturn has its own trap. In 1990 it was commercial paper. In 2018 it was interest-only lending. In 2026, it is private debt — and the off-the-plan contracts it is quietly propping up.

The market has turned. The cash rate sits at 4.35 per cent after three rises this year. Borrowing capacity has been cut with each move. The premium end of Sydney is flat to falling, and vendors are adjusting to the new numbers. That is the market as it stands today.

Yet across the city, buyers are still being asked to sign contracts at prices struck for a different market — the market of late 2024 and 2025, when developers ran their feasibilities, priced their stock and locked in their funding. Those are yesterday’s prices. And an off-the-plan contract asks you to pay them in two, three or four years’ time, whatever the market does in between.

Who is actually funding the pipeline

Understand who lends to developers now, and you understand the risk. The banks stepped back from residential development years ago. Private credit stepped in. Non-bank lenders now write roughly a quarter of all residential development lending in Australia — a sector tipped to nearly double in size by the end of the decade.

This money is not patient money. It targets double-digit returns. It charges accordingly. A developer paying private-credit rates on a construction facility is bleeding interest every month a project runs late — and every month unsold stock sits on the books. That pressure flows in one direction: sell early, sell hard, and hold the contract price at all costs, because the lender’s feasibility depends on it.

The regulator has noticed. ASIC has spent this year warning private credit funds that their valuations must reflect real conditions, not the assumptions made before rates rose. Surveillance is active. Enforcement investigations are underway. When the umpire starts asking lenders whether their development loans are worth what the books say, that tells you something about the projects those loans are secured against.

What you are really signing

An off-the-plan contract is not a purchase. It is a commitment. You agree today to settle at a fixed price years from now, on a property that does not exist, financed by a loan you do not yet have, in a market no one can predict.

You hand over a ten per cent deposit and you carry three risks the entire time. Market risk: values can fall between exchange and settlement, and your price does not move with them. Finance risk: your pre-approval expires long before the building is finished, and your lender reassesses you — and the property — on settlement-day conditions. Completion risk: the developer has to survive long enough, and remain funded well enough, to finish the building at all.

In a rising market, buyers wear these risks and are paid for them. In a falling market, you wear the same risks and the payment runs the other way.

Sunset clauses: locked in, not protected

Most buyers believe the sunset clause is their escape hatch. Read it again. The sunset date is the deadline for the developer to register the plan or complete the building — but nearly every developer contract carries extension rights. Delays for weather, approvals, labour, “matters beyond the vendor’s control”. Each extension pushes your settlement further out while your deposit stays locked in and your price stays fixed.

NSW law does protect buyers from one specific abuse. Since the 2015 amendments to the Conveyancing Act, a developer cannot rescind under a sunset clause without the purchaser’s written consent or a Supreme Court order — a reform built to stop developers deliberately running out the clock in a rising market so they could resell at higher prices.

Note what that law was designed for: a rising market, where the developer wants out and the buyer wants in. In 2026 the positions reverse. Values are softening. The developer does not want to release you — the developer needs you locked in at the contract price, because you are the feasibility. The buyer who wants out has no equivalent statutory escape. The sunset regime keeps the door shut in both directions, and today it is the buyer standing on the wrong side of it.

Will the developer still be standing?

Construction has led national insolvencies for four consecutive years. The latest financial year saw the first marginal easing — a fall of a few per cent from record levels. That is not recovery. That is the survivors of a cull. Many builders still carry legacy losses from fixed-price contracts signed before costs escalated, and the developers who engage them are carrying private-credit facilities priced for a market that no longer exists.

To be precise about what the law does and does not protect. Since the December 2019 reforms, deposits and instalments on NSW residential off-the-plan contracts must be held in a trust or controlled money account and cannot be released to the developer before settlement — a deliberate safeguard against developer insolvency. Your cash deposit should come back if the project collapses. What the law cannot return is time: two or three years with your capital sterilised, your borrowing position aged, and the market moved on without you.

And one gap remains that buyers rarely see coming. Developers in difficulty sometimes transfer the site to a new entity — a restructure, a rescue, a sale to another operator. The new entity may claim it is not bound by your contract, leaving your only remedy an action against the original developer, which by then may be an insolvent shell. The Law Society has flagged exactly this scenario in its submissions on off-the-plan reform. The deposit-in-trust rules also do not extend to vacant land or non-residential lots, where the older, harsher rules of the queue still apply.

When the valuation comes in under the price

Here is the mechanism that catches most buyers, and no marketing suite will explain it. Your bank does not lend against your contract price. It lends against a valuation ordered at settlement — on the finished product, in the market of that day.

In a soft market, shortfalls on new apartments of five to fifteen per cent against contract are not unusual, and the gap is widest in oversupplied precincts where the valuer can see hundreds of identical units settling at once. The shortfall must be covered in cash. Your ten per cent deposit was your equity; now it is swallowed just bridging the gap, and the bank still wants its normal deposit on top.

And remember the structural problem underneath: an off-the-plan price already carries the developer’s marketing costs, selling commissions and margin. You buy at retail. The resale market has never agreed to pay retail, and in a downturn it refuses outright.

The supply wave is already in the system

Now set all of this against what is coming. Approvals for apartments and townhouses have surged — at one point this year running at double the prior year’s rate — with close to 200,000 homes approved nationally over twelve months. In Sydney, the planning system has been rebuilt to accelerate density: the Transport Oriented Development program around dozens of stations, the Low and Mid-Rise Housing Policy across every well-located precinct, the Housing Delivery Authority and a reinstated State Facilitated Development pathway fast-tracking major residential schemes.

Behind the approvals sits a second, quieter pipeline: developers have spent two years securing options over amalgamated sites across these rezoned corridors. Options cost little to hold. When conditions allow, they convert to projects — and every one of them will be sold off the plan before a slab is poured, because that is what the private lender requires.

None of today’s approvals completes before 2028 at the earliest. So the wave lands into an unknowable future market — and the buyer signing today is the one underwriting it. If that market is soft, the settlement valuations will say so, street by street, tower by tower, all at once.

I make the usual distinction here, because it matters. Genuine scarcity — established homes on land in tightly held suburbs, boutique buildings that cannot be replicated under today’s costs — behaves differently through every cycle I have seen. Mass-produced stock in high-supply corridors does not. The risk in this article is concentrated where the cranes are concentrated.

What I tell buyers in this cycle

First: in a falling market, a fixed future price is a liability, not a bargain. Any incentive — stamp duty savings, rebates, upgrades — must be weighed against the full width of the risks above, not against the brochure.

Second: if you must buy off the plan, stress-test the deal the way a lender would. Assume a ten to fifteen per cent valuation shortfall and a cut to your borrowing capacity. If the purchase only works when nothing goes wrong, it does not work. Investigate the developer’s funding, their completions through the last downturn, and who holds your deposit. Have a specialist solicitor take the sunset and extension clauses apart line by line before you sign — not after.

Third: compare the alternative honestly. An established property is priced by today’s market, inspected with your own eyes, settled in weeks, and carries no developer between you and your title. In a cautious market, certainty is the asset class.
