Common Mistakes Buying Off-the-Plan as a First Home Buyer

I thought buying off-the-plan would give me more time to save.

That was the first mistake. When you sign an off-the-plan contract in Southern Sydney, you commit to a purchase price today for a property that might not settle for 18 to 24 months. That sounds like breathing room, but the clock starts ticking the moment you sign. Your pre-approval expires. Lender policies change. Interest rates shift. The property valuation at settlement might come in lower than the contract price, and suddenly the deposit you thought was enough no longer covers what the bank requires. I learned this when I realised my entire timeline was built on hope, not certainty.

Off-the-Plan Settlements Don't Wait for Your Finances to Catch Up

Your home loan application needs to be ready before settlement, not when the developer tells you the property is complete. Most off-the-plan contracts in Southern Sydney include a sunset clause between 18 and 36 months, but developers can bring settlement forward if construction finishes early. When that happens, your lender reassesses everything: your income, your employment, your credit file, and the property value. If any of those have changed since you signed, your loan might not be approved on the same terms, or at all.

Consider a buyer who purchased an apartment in Hurstville in late 2024 with a 10% deposit and a contract price of $750,000. At the time, they secured conditional pre-approval through the Australian Government 5% Deposit Scheme. Settlement was scheduled for mid-2026, but the developer notified them in early 2026 that the building would be ready three months ahead of schedule. By then, lender policy had tightened. The buyer's income hadn't changed, but the bank's servicing buffer had increased, and the valuation came back at $720,000. The shortfall meant they either had to find an additional $30,000 in cash or walk away from the contract and lose their deposit. They hadn't prepared for that gap because they thought time was on their side.

Stamp Duty Concessions Depend on the Property Value at Settlement, Not at Contract

Most first home buyers assume the stamp duty concession locks in when they sign the contract. It doesn't. In New South Wales, the First Home Buyers Assistance Scheme provides a full transfer duty exemption on properties valued up to $800,000 and a sliding concession between $800,000 and $1,000,000. That valuation happens at settlement, not at contract date. If the market has moved and your property is now worth $850,000 instead of $780,000, you lose part of the concession and owe thousands more in duty than you budgeted for.

Victoria offers an extended off-the-plan stamp duty concession that runs until 31 October 2026, where duty is calculated on the land value at contract date only, not the finished property value. That concession is available to a broader group of buyers, not just first home buyers, and expires after the eligible period. If your contract in Victoria was signed after that date, or if you're settling in New South Wales, Queensland, or another state, the valuation risk sits with you.

Lenders Value Off-the-Plan Properties Differently, and That Affects Your Deposit

A bank will not lend against a contract price. They lend against their valuation of the completed property at settlement. If the valuer determines the property is worth less than you agreed to pay, the shortfall comes out of your deposit. A 10% deposit on a $700,000 contract is $70,000. If the property values at $670,000, the bank calculates your loan-to-value ratio on $670,000, not $700,000. To borrow 90% of $670,000, you need a $67,000 deposit, which leaves you $3,000 short of the contract price. You still owe the developer $700,000, so you need to find that $30,000 in cash or the sale falls through.

Some lenders apply a further discount to off-the-plan valuations because the property hasn't settled yet. That discount can be 5% to 10% depending on the lender, the location, and the size of the development. It's not something most buyers know to ask about until it's too late. When we finally understood how valuations worked, the relief came from knowing we could structure the home loan around a realistic figure, not the number on the contract.

Your Income and Employment Need to Be Stable from Contract to Settlement

Pre-approval is not approval. It's conditional, and those conditions get reassessed at settlement. If you change jobs, take parental leave, move from full-time to part-time work, or have any gap in employment between signing the contract and settling, the lender will reconsider your application. That reconsideration can result in a lower borrowing capacity, a higher interest rate, or a declined application.

In our experience, buyers who sign off-the-plan contracts while on probation or in casual roles often find themselves unable to settle because their employment didn't stabilise in time. Lenders want to see at least three months of payslips in your current role, and some require six months for casual or contract workers. If settlement lands before that threshold, you might not meet the lender's servicing criteria even if your income hasn't changed. That's not a small risk when you've already paid a deposit and signed a binding contract.

You Can't Assume the Same Lender Will Approve You at Settlement

Lender policies change. A lender who offered you pre-approval 18 months ago might not be the right lender at settlement, or might not approve you at all under their updated criteria. Some lenders have tightened their appetite for off-the-plan properties in high-density areas or developments with a high proportion of investor buyers. Others have increased their interest rate buffers or reduced maximum loan-to-value ratios for apartments.

If your original lender pulls out or declines your application at settlement, you need time to find another lender, submit a new application, and get a new valuation. Most off-the-plan contracts give you 14 to 30 days to settle once the developer issues a notice of completion. That's not enough time to start a home loan application from scratch. The only way to protect yourself is to review your financial position and your lender's current policy at least three months before the expected settlement date, and have a backup lender ready if needed.

The First Home Owner Grant Doesn't Always Apply to Off-the-Plan Apartments

The New South Wales First Home Owner Grant is $10,000 and applies only to new builds or substantially renovated homes, with a purchase cap of $600,000 or a land and build cap of $750,000. Most off-the-plan apartments in Southern Sydney exceed that $600,000 cap, which means buyers in suburbs like Kogarah, Rockdale, or Hurstville often don't qualify for the grant even though they're purchasing a new property. The grant is more commonly accessible to buyers purchasing land and building a house, or purchasing a new townhouse or villa under the cap.

If you're relying on that $10,000 to cover part of your settlement costs, confirm your eligibility before you sign. The stamp duty concession is more valuable for most off-the-plan buyers in this price range, but it's not a substitute for the grant, and you can't assume both will apply. When I realised we didn't qualify, it felt like the goal posts had moved, but they hadn't. I just hadn't checked.

Low Deposit Schemes Have Annual Place Limits and Lender Panels That Change

The Australian Government 5% Deposit Scheme removed income caps and annual place limits from 1 October 2025, but applications are still made through a participating lender panel. As of 2026, that panel includes 31 lenders comprising three major banks and 28 non-major lenders. Not all lenders on the panel accept off-the-plan properties, and those that do often apply stricter criteria than they would for an established home. Some lenders cap the loan amount, restrict the size or type of development, or require a larger deposit than the 5% minimum.

Help to Buy launched on 5 December 2025 and allows the Australian Government to contribute up to 40% of the purchase price for a new home, but it cannot be combined with the 5% Deposit Scheme. Buyers using Help to Buy require a minimum 2% deposit, but income limits are $100,000 for individuals and $160,000 for joint applicants. Property price caps apply and vary by location. If your income exceeds those caps, or if the property you're purchasing exceeds the regional price cap, you won't qualify. That's a hard line, and it caught me off guard because I thought any new home would be eligible.

Call one of our team or book an appointment at a time that works for you. We'll walk through your contract, your deposit, your lender options, and the timeline between now and settlement. Off-the-plan purchases feel overwhelming because so much can change between signing and settling, but you don't have to carry that on your own. We've sat with buyers who thought they were too far in to ask for help, and every time, the relief came from knowing someone else understood the process and could see the gaps before they became problems. You're not behind. You're exactly where you need to be to get this right.
