When to Lock In Your Off-the-Plan Purchase

What first home buyers in Collingwood Park need to know about deposits, lender approvals, and stamp duty before signing an off-the-plan contract.

Off-the-plan properties let you secure a home before it's built, usually with a smaller initial deposit than an established property.

The settlement timeline can stretch anywhere from 12 to 36 months depending on the development, which gives you time to save and prepare. That same timeline creates specific challenges around lender approval, changing property values, and managing your budget through to completion. For buyers in Collingwood Park, where newer estates and townhouse developments are part of the landscape, knowing how the process differs from a standard purchase keeps you in control from contract to keys.

How Lender Pre-Approval Works With a Long Settlement

Pre-approval gives you a conditional commitment from a lender based on your current income, expenses, and deposit. Most pre-approvals remain valid for three to six months. If your off-the-plan property settles in 18 months, that approval will expire long before you need the funds.

You apply for formal approval closer to settlement, usually once the property reaches practical completion or is within a few months of settlement. The lender reassesses your financial position at that time. If your income has dropped, your living expenses have increased, or lending criteria have tightened, the loan amount you were originally pre-approved for may no longer be available. We regularly see this with buyers who change jobs, take parental leave, or accumulate additional debt during the construction period.

Consider a buyer who signed a contract in early 2025 with a 10% deposit and strong pre-approval. By mid-2026, they had moved from full-time to contract work and added a car loan. At formal assessment, the lender reduced the approved amount by $40,000. The buyer had to find extra funds at settlement or renegotiate the contract. Keeping your financial position stable between contract and settlement is not optional if you want the loan to settle smoothly.

What Happens If the Property Value Drops Before Settlement

The contract price is set when you sign. The lender's valuation is conducted closer to settlement, based on the market at that time. If the valuer assesses the completed property below the contract price, the lender will only provide a loan based on the lower valuation.

Under the Australian Government 5% Deposit Scheme, the purchase price and the lender's assessed value must both sit at or below the applicable price cap. For Collingwood Park, the cap is $1,000,000 under the capital city and regional centres category. If you sign a contract for $480,000 and the property is later valued at $450,000, the lender bases the loan on $450,000. You either need to make up the shortfall in cash or renegotiate the contract with the developer.

This scenario is less common in growth areas with strong demand, but it can occur if the development is delayed, market conditions shift, or the local area does not develop as anticipated. Buyers should factor in the possibility and avoid borrowing at the absolute edge of their capacity.

Deposit Structure and Timing for Off-the-Plan Contracts

Most off-the-plan contracts require an initial deposit of 5% to 10% on signing, with additional progress payments as construction advances. The structure varies by developer. Some require a second payment at slab-down or lock-up stage. Others hold all payments until settlement.

You need to confirm the payment schedule before you sign, as it affects how much you need saved and when. If you are relying on the First Home Owner Grant for part of your deposit, note that the grant is usually paid at or after settlement, not at contract. You cannot use grant funds for the initial deposit unless you have arranged a deposit bond or other interim finance.

A deposit bond is a guarantee from an insurer that the deposit will be paid if you default. It allows you to defer the cash outlay until settlement. Fees apply, and not all developers accept deposit bonds. If your contract allows it, a bond can free up cash for other costs during the construction period.

Stamp Duty Timing and Eligibility in Queensland

In Queensland, first home buyers purchasing a new home can access a full transfer duty concession with no price cap under the first home new home concession, provided the contract was signed on or after 1 May 2025. Duty is reduced to nil on the residential land component. For agreements entered into on or after 1 August 2026, at least one applicant must be an Australian citizen, permanent resident, or specified foreign retiree.

The concession applies at settlement, not at contract. You lodge the transfer duty return and claim the concession through the Queensland Revenue Office when the property is registered in your name. If you no longer meet the eligibility criteria at settlement, such as principal place of residence requirements, the concession may not apply. Buyers must move into the property within 12 months of settlement and occupy it as their principal place of residence for at least 12 continuous months.

The $15,000 First Home Owner Grant for contracts signed from 1 July 2026 is also paid at or after settlement for new homes. Both the duty concession and the grant can be used alongside the Australian Government 5% Deposit Scheme, giving Collingwood Park buyers access to multiple layers of support if they meet the eligibility requirements for each.

Interest Rate Changes Between Contract and Settlement

Your contract price is fixed. Your interest rate is not. If rates rise during construction, your borrowing capacity may reduce or your repayments may increase beyond what you budgeted for at contract.

We regularly see buyers lock in a contract based on a serviceability assessment at one rate, only to find that a rate increase six months later reduces what they can borrow or pushes their repayments higher than anticipated. If you are borrowing close to your maximum capacity, a rise of even 0.5% can be material.

You cannot fix your home loan interest rate until formal approval is granted and the loan is ready to draw down, which is usually at or just before settlement. Some lenders allow you to lock in a rate 90 days before settlement if the loan is formally approved. Until then, you are exposed to rate movements. Factor a buffer into your budget to absorb potential increases without derailing your capacity to settle.

What First Home Buyers Should Check Before Signing

Before you commit to an off-the-plan contract, confirm the deposit and progress payment schedule in writing. Check whether deposit bonds are accepted. Understand the estimated completion date and whether there is a sunset clause that allows either party to exit if the development is not finished by a certain date.

Review the inclusions and finishes specified in the contract. Off-the-plan marketing materials can be illustrative rather than binding. If something is important to you, such as appliances, flooring, or fixtures, confirm it appears in the contract or attached schedule.

Obtain independent legal advice. A conveyancer or solicitor experienced in off-the-plan contracts will identify clauses that shift risk to the buyer, such as variation clauses that allow the developer to change the design, materials, or layout without your consent.

Speak to a mortgage broker before you sign, not after. We can run a serviceability assessment based on your current position, walk through how the timeline affects your loan application, and flag any issues early. Collingwood Park sits within a growing corridor with a mix of established homes and newer developments. Lenders are generally familiar with the area, but property type, street location, and developer reputation all influence how they assess the security.

Off-the-plan buying gives you time to prepare, but that time also introduces variables you need to manage. Income stability, deposit planning, lender reassessment, and market movements all play a role between contract and settlement. Getting the structure right from the start keeps those variables manageable.

Frequently Asked Questions

Can I use my pre-approval for an off-the-plan property that settles in 18 months?

What happens if the property is valued below the contract price at settlement?

The lender will base the loan amount on the lower valuation, not the contract price. You will need to make up the difference in cash or renegotiate the contract with the developer.

Can I use the First Home Owner Grant for my initial deposit on an off-the-plan purchase?

The grant is usually paid at or after settlement, not at contract. You cannot use it for the initial deposit unless you arrange a deposit bond or other interim finance to cover the upfront amount.

First home buyers purchasing a new home can access a full transfer duty concession with no price cap, provided the contract was signed on or after 1 May 2025 and eligibility criteria are met. Duty is reduced to nil on the residential land component.

Can I lock in my interest rate when I sign an off-the-plan contract?
