Buying Off-the-Plan in Australia: What to Know Before You Sign

Why buyers choose off-the-plan

There are good reasons people are drawn to it:

• Today's price, tomorrow's settlement. You agree the price now, which can help if you expect prices to rise, though they can also fall.
• More time to save. A smaller deposit now and a long runway to settlement can make the numbers feel more manageable.
• Possible stamp duty concessions. Some states and territories offer concessions on new builds. These depend on your circumstances and change often, so check the current rules with your conveyancer or solicitor.
• A brand-new home. Modern layouts, new fittings and, usually, a builder's warranty.

None of these are guaranteed outcomes, and the benefits depend on your situation. What I can tell you is that off-the-plan works best when the finance strategy is built around the construction timeline from day one.

‍

The part most buyers don't see coming: two timelines

Every off-the-plan purchase runs on two timelines at once. There's the build journey and there's the lending journey. They were never designed to move at the same pace, and the gap between them is where things tend to go wrong.

Here's the build journey in plain English:

1. Sign the contract and pay the deposit.
2. Construction. Often the longest stage.
3. Practical completion. The building is finished and ready to be occupied.
4. Valuation and formal loan approval. The lender values the completed property and assesses your finances again.
5. Settlement notice. You're told your settlement date.
6. Settlement. Funds are released and ownership transfers to you.

Your lender will usually want to see your contract at pre-approval stage, so it's worth getting this right early. But here's the key point: a pre-approval at the start is not a guarantee of approval at the end. Pre-approvals are time-limited, and the lender will assess you again close to settlement, against the policies, rates and your finances as they are then, not as they were when you signed.

Risk 1: the valuation shortfall

A valuation shortfall happens when the bank's valuation of your completed property comes in lower than the price you agreed to pay. Your contract price doesn't change. The bank's lending is based on its valuation, so the gap is yours to fund.

Here's a simple illustration. Say you contract to buy for $750,000, with a $150,000 deposit and a $600,000 loan in mind. At completion, the bank values the property at $700,000. If the lender's maximum loan is 80% of valuation, that's $560,000, so you'd need to find an extra $40,000 on top of your deposit and your purchase costs. If the lender will lend above 80%, Lenders Mortgage Insurance may apply, and that's an added cost.

This is an illustration only. Every lender has its own policy on valuations, maximum LVRs and how they handle shortfalls, and your own numbers will differ.

 But the principle holds: you pay the contract price regardless of the valuation.

That's why I stress-test off-the-plan clients before they sign, across a range of valuation outcomes, so the question isn't "what if?" on settlement day. It's "we planned for this".

Risk 2: your finances change, or the rules do

Over a build that can run for years, a lot can happen:

• Your income or employment changes.
• Your living costs or family situation change.
• You take on new debt, such as a car loan, buy-now-pay-later or a higher credit card limit, which can reduce what you can borrow.
• Lender policies, assessment rates or interest rates move.
• Your lender changes its appetite for the type of property or the project.

None of these are unusual. They're exactly why I recommend not treating pre-approval as the finish line, and why I keep a close eye on any major changes with your financial position as the build progresses.

Risk 3: your deposit

Off-the-plan deposits are commonly 5% to 10% of the purchase price, paid at exchange and usually held in trust until settlement. On a $600,000 purchase, a 10% deposit means $60,000 tied up for the entire build.

There are alternatives, such as deposit bonds or bank guarantees, which can free up cash during construction. They come with their own costs and conditions, so your conveyancer or solicitor should confirm they're suitable and accepted under your contract.

The other side of the deposit is simple but serious: if you can't settle, for example because finance falls through, you may forfeit the deposit, and the contract may expose you to further consequences. That's why checking your finance position early and often matters so much.

Risk 4: the developer and the contract

A brochure and a display suite tell you what the project will look like. They tell you very little about whether it will be delivered, on time, to the standard promised. A developer not completing a project is one of the most significant off-the-plan risks, so this homework matters. Six questions worth asking before you fall in love with the finishes:

1. Track record. What else have they built, and was it delivered on time and to standard?
2. Who's behind it? Projects are often sold through a company set up for that one development. A free ASIC company search can show how long it has existed.
3. How well has it sold? Developers usually need a portion sold before construction starts. Ask the sales agent.
4. Approval status. Has the development approval actually been granted? Council trackers and the contract's disclosure documents can help.
5. Warranty and defects. How are issues after move-in handled, and what insurance applies in your state?
6. Finishes in writing. Make sure the schedule of finishes is attached to the contract. Display suites and sales chat don't count.

Then there's the contract itself. Off-the-plan contracts are usually drafted by the developer's side, and they contain terms that don't appear in an established-home contract, such as sunset clauses, variation rights and deposit terms. Cooling-off periods, disclosure requirements and deposit rules also differ between states and territories, and in some places there's no statutory cooling-off period at all.

I want to be clear about my role here. I'm a mortgage broker, not a solicitor. Your conveyancer or solicitor must review the legal terms of your contract. What I do is look at the contract through a lending lens, and flag anything that could affect your finance, so your whole team is working from the same page.

How to protect yourself

The good news is that most off-the-plan risks are manageable when you plan for them early. These are the steps I'd encourage every buyer to consider:

• Get your finance strategy sorted before you sign, not after. Know your borrowing capacity, your deposit strategy and your position across a range of scenarios.
• Build a cash buffer beyond your deposit to help cover a possible valuation shortfall and purchase costs.
• Avoid new debt or credit applications between contract and settlement unless you've spoken to your broker first.
• Keep your savings accessible. Locking funds into a term deposit without break options can cause problems at settlement.
• Tell your broker about any change to your job, income or circumstances as soon as it happens.
• Re-confirm your finance well ahead of settlement. I generally recommend 3 to 6 months out, which allows time to act if something has shifted.
• Build your team early: a conveyancer or solicitor, a mortgage broker and, where relevant, a valuer and a building inspector for your pre-settlement inspection.

None of this removes risk entirely. But it replaces surprises with a plan.

How I help: Blueprint to Settlement

I built my Blueprint to Settlement service around one idea: manage the gap between the build and the lending, deliberately, rather than leaving it to chance.

• I front-load the work. Before any formal application, I do the deep review of your credit, servicing, contract and lender options while there's still time to act on what I find.
• I run the two timelines side by side. I map your build milestones against your lending milestones from day one, so we know when each action needs to happen.
• I look after your credit file. Rather than repeated applications over several years, we do the heavy assessment once and keep it current with light-touch check-ins, aiming to avoid unnecessary credit enquiries.
• I plan for change. Lender policy can shift over a multi-year build, so I look at your position across several lenders up front, to give you options if one lender's settings change. Of course, I can't guarantee any outcome or any lender's approval.
• I stay with you the whole way. One broker from your first conversation through to settlement and beyond, so you're never re-explaining your situation to someone new.

The engagement runs from financial assessment and a lending-focused contract risk report, through milestone monitoring while the building goes up, to settlement coordination alongside your conveyancer or solicitor. I also connect you with trusted professionals suited to your state and property type.

It's offered at a transparent, fixed fee of $2,000 plus GST, so you know what you're paying before you start. Any commission I may receive from a lender, and how I'm paid more generally, is set out in my Credit Guide and explained before you proceed. My job, and am required by law to do so, is to recommend the strategy and loan that suit your objectives, not the one that's easiest for me or pays more.

Thinking about buying off-the-plan?

The best conversation to have is the one before you sign. If you're considering an off-the-plan purchase, or you've already got a contract and want to understand your finance position, I'd love to chat. Ask me for a copy of my Buying Off-the-Plan in Australia guide, or book a time to talk through your situation.
