Buying Off the Plan: A Practical Conveyancing Guide

Buying “off the plan” means purchasing a property that doesn’t exist yet, at least not in bricks and mortar. You’re buying off drawings, specs and a developer’s vision, rather than walking through a finished home. That distinction is exactly why off-the-plan conveyancing (often referred to as new build conveyancing) plays by different rules from a standard property purchase.

Off-the-plan property buying comes with quirks, like delays and clauses that can bite if you skim them. This guide walks you through what to watch for and how to stay in control from contract to keys.

Why do buyers choose off the plan properties?

The truth is, off the plan buying isn’t some fringe move anymore. The ABS reported 18,406 total dwellings approved in November 2025 (seasonally adjusted), and a good chunk of those get snapped up well before they’re finished. 

Here’s why buyers keep lining up, and what we see driving it day in, day out at Titlespace.

• A brand-new property — No previous owners, no mystery renovations, no inherited problems. Everything is untouched and built to current standards, which is a big psychological win for many.
  

• Modern designs and inclusions — Think open-plan layouts, energy-efficient features and finishes that don’t scream “early 2000s”. These new builds are designed for how people actually live now, not how they lived twenty years ago.

• Possible stamp duty concessions — Some states offer off-the-plan stamp duty concessions that reduce how much transfer duty you pay on a new build purchase. For example, Victoria lets eligible buyers calculate duty on the contract value less future construction costs, rather than the full expected finished price.

• More time to get your finances ready — Settlement can be months or even years away. That breathing room helps buyers build savings, plan lending and avoid the scramble that comes with fast turnarounds.

How off-the-plan purchasing works: step by step

Step 1: Reviewing of the contract

This is where off-the-plan conveyancing really starts to earn its keep, because you’re not reviewing a neat little contract for a finished home. You’re signing up for a future property, which means the paperwork covers every “what if” under the sun, plus a few the developer thought of at 2 am.

These contracts usually come stacked with plans, specs, proposed timelines, disclosure documents and clauses that let certain changes happen along the way. They’re longer because they need to explain what happens if things stall or take a scenic route.

Step 2: Exchange and deposit

Exchange usually happens well before construction is finished, sometimes before it’s even started. You’ll sign the contract and pay a deposit, commonly around 10%, though this can vary depending on the project and state. That deposit is typically held in a trust account until settlement, not handed straight to the developer.

Step 3: The off-the-plan cooling-off “like” period

Off-the-plan transactions usually have a short window between signing and the final exchange of contracts for your solicitor to review the contract and for you to step back if needed. How long it lasts and how it works depends on the state and the contract. In practice, it’s not a free pass to change your mind without consequence. There are limits, conditions and, in some cases, costs involved.

Step 4: The construction phase

This is the long middle. While the property is being built, you’ll get updates and the occasional variation that makes you squint at the plans again. Delays are common due to weather, material procurement, trades or approvals taking their sweet time. Developers may also make permitted tweaks to layouts or finishes, which is why the contract and off-the-plan conveyancing matter so much upfront.

This stage rewards patience and clear communication, because remember, quiet doesn’t mean nothing’s happening. It usually means things are moving, just not at a Hollywood pace.

Step 5: Settlement

Settlement for off-the-plan purchases happens once construction is complete and the property is legally ready to transfer. Final documents are issued, inspections are arranged where applicable and timelines suddenly matter again. If dates move, processes adjust. It’s different to established homes, but with the right handling, it doesn’t need to feel chaotic.

Key risks to understand before buying off the plan

Buying off the plan can be rewarding, but it’s not a plug-and-play purchase. The risks aren’t deal-breakers, but they are real, and they tend to show up slowly, not loudly.

• Construction delays are the most common. Build timelines often stretch beyond original estimates. That means settlement can drift, sometimes by months, sometimes longer. If you’re planning around fixed dates or life events, flexibility is non-negotiable.
  
• Changes to layout, size or finishes can come into play. Most off-the-plan contracts allow developers to make certain amendments as long as they’re within agreed parameters. That doesn’t usually mean a completely different apartment, but it can mean small shifts that matter if you weren’t expecting them.
• Market conditions can also change between contract and completion. If values dip, the finished property may be valued lower than the original contract price. That can affect lending and require buyers to contribute more at settlement. It’s not common, but it’s a risk that exists purely because of the longer timeframe.
• Finance approval is another moving target. A loan approved today doesn’t automatically roll forward to settlement years later. Lenders reassess income, expenses and market conditions, which can change the numbers. Planning for this early makes a difference.

Why do I need off-the-plan conveyancing?

As we discussed, off-the-plan purchases come with more chances for something to drift. The right conveyancer keeps the whole thing moving and stops surprises from turning into expensive hobbies. Here’s what that looks like in real life.

1. A conveyancer reviews contracts and disclosure documents

New build conveyancing starts with a proper contract review, including the developer’s disclosure documents, plans and specifications. The goal is to understand what you’re actually buying, what can change and what happens if timelines blow out.

2. They explain rights and obligations in plain English

No one wants a legal lecture. A conveyancer translates the contract into practical terms, so you know what the developer can do and where the boundaries are, without the jargon hangover.

3. They monitor milestones and deadlines

Off-the-plan transactions have dates that matter now, even when settlement is a distant concept. Your conveyancer tracks key timeframes and notices so nothing gets missed while you’re busy living your life.

4. They manage settlement and compliance

Off-the-plan conveyancing can involve extra steps leading into settlement, which is a polite way of saying there are more documents, moving deadlines and people needing something yesterday. Your conveyancer coordinates the paperwork and lines things up with your lender so settlement doesn’t turn into a last-minute scramble.

5. Acting as a buffer between buyer, developer and lender

You shouldn’t have to play middleman between a developer, a bank and a pile of contract documents. Your conveyancer handles that back-and-forth so you get clear answers and fewer headaches.

Is buying off the plan right for you?

Buying off the plan works best for people who are happy to play the long game. If you need fixed dates or keys in hand next week, it’s certainly not ideal. The difference is expectations. Go in clear, and the process feels manageable and less mysterious.
