Simple hacks to finance an off-the-plan property

Structuring your home loan before construction starts

Off-the-plan purchases require pre-approval 12 to 24 months before settlement, meaning your financial position, interest rates, and lender policy may all shift before you take possession. Successful buyers lock in a home loan structure that accounts for construction delays, valuation changes at completion, and evolving serviceability requirements over the build period.

Consider a buyer who secured pre-approval for a two-bedroom apartment in a new Canning Vale precinct at $550,000 with an 8% deposit. The lender provided approval based on the contract price, but by settlement 18 months later, the completed building valuation came in at $520,000. The buyer faced a valuation gap of $30,000 and needed to bring additional funds to settlement to meet the lender's LVR requirement. Structuring the loan with a 10% deposit at the outset and requesting a formal valuation review clause in the approval would have mitigated this risk.

Pre-approval for off-the-plan property is typically valid for 90 to 120 days, but the purchase contract binds you for the full construction period. Most lenders require a full re-assessment of your income, expenses, and credit profile at the time of formal loan application, typically three months before the anticipated settlement date. If your circumstances change during construction, such as a job change, new debt, or fluctuating self-employment income, the lender may reduce your borrowing capacity or decline the loan entirely. First home buyers entering the market through off-the-plan purchases should prepare for this extended timeline by maintaining stable employment and minimising new credit commitments during the build phase.

If you are accessing the Australian Government 5% Deposit Scheme, the guarantee applies only if the property value at settlement remains at or below the applicable price cap. For Canning Vale and surrounding areas classified within the Perth metropolitan region, the cap is $850,000 for capital cities and regional centres. If the completed property is valued above this threshold at settlement, the guarantee is withdrawn and the buyer must either pay LMI or increase their deposit to 20%.

Fixed rate, variable rate, or split loan structure for a delayed settlement

Locking in a fixed interest rate at the time of pre-approval does not mean that rate applies at settlement. Most lenders issue a rate lock only when the loan is formally drawn down, meaning the rate you receive will reflect the market at the time of settlement, not the time of contract.

A split loan structure is commonly used for off-the-plan purchases where settlement timing is uncertain. Buyers may fix 50% to 70% of the loan to protect against rate increases during construction, while keeping the remainder on a variable rate to retain access to an offset account and flexibility for additional repayments. This structure also mitigates the risk of break costs if the buyer needs to refinance or sell before the fixed term expires.

If your settlement is delayed beyond the original expected completion date, your lender may require an extension of the pre-approval, which triggers a fresh serviceability assessment. Interest rates may have moved, your income may have changed, or lender policy may have tightened. Buyers who were approved under previous serviceability buffers may no longer meet the 3.0 percentage point buffer applied by all ADIs from February 2026. If the lender cannot extend the approval, the buyer may need to refinance to a different lender before settlement or risk breaching the contract.

Western Australia removed stamp duty caps for first home buyers of new homes from May 2026, meaning eligible buyers pay no transfer duty on off-the-plan purchases regardless of the contract price, provided at least one applicant is an Australian citizen or permanent resident. This applies statewide under the First Home Owner Rate framework and removes a significant upfront cost barrier for buyers entering the market through off-the-plan developments in Canning Vale and similar growth corridors.

Valuation gap and how lenders calculate LVR at settlement

Lenders calculate the loan-to-valuation ratio at settlement based on the lower of the contract price or the completed property valuation. If the valuation comes in below the contract price, the buyer must either increase their deposit to meet the agreed LVR or pay LMI on the higher ratio.

In a scenario where a buyer contracts for a $600,000 townhouse in Canning Vale with a 10% deposit, the buyer expects to borrow $540,000 at an LVR of 90%. If the bank's valuer assesses the completed property at $570,000, the lender recalculates the LVR as 94.7% based on the lower valuation. The buyer must bring an additional $27,000 to settlement to return the LVR to 90%, or accept a higher LMI premium if the lender permits lending above 90% in that scenario.

Valuation gaps are more common in oversupplied apartment markets where multiple developments settle simultaneously, or where the developer's marketing price exceeds the market's assessment of comparable completed sales. Buyers purchasing in precincts with high volumes of off-the-plan stock should request a desktop valuation before exchanging contracts and factor a 5% to 10% valuation buffer into their deposit planning.

If the valuation gap cannot be closed with additional cash, some buyers negotiate with the developer to reduce the contract price or delay settlement until market conditions improve. This is rarely successful unless the development is under-sold or the builder is motivated to finalise settlements quickly. The more reliable approach is to structure the loan with a higher deposit from the outset and ensure your borrowing capacity can withstand a moderate valuation adjustment.

Sunset clauses and loan expiry during extended construction

Most off-the-plan contracts include a sunset clause that allows either party to terminate the contract if construction does not reach practical completion by a specified date, typically 24 to 36 months from the date of contract. If the developer invokes the sunset clause, the buyer's deposit is refunded, but the pre-approval expires and the buyer loses any price growth that occurred during the construction period.

From the lender's perspective, an expired pre-approval requires the buyer to restart the application process under current policy settings. If lending standards have tightened, interest rates have risen, or the buyer's financial position has weakened, the buyer may no longer qualify for the same loan amount. Buyers who entered contracts during periods of lower interest rates may find their serviceability has deteriorated under the higher assessment rate, leaving them unable to proceed even if the developer completes the building.

If you are purchasing with a partner or co-borrower, changes to their income or employment during the construction period may also affect the loan. Lenders assess all applicants at the time of formal lodgement, and a reduction in one borrower's income can reduce the combined borrowing capacity enough to create a shortfall. Investment property buyers should also be aware that acquiring additional property or debt during the construction period will reduce serviceability for the off-the-plan settlement.

Progress payments, construction loans, and interest-only periods

Off-the-plan apartment and townhouse purchases typically require no progress payments during construction, with the full loan drawn down at settlement. House and land packages, however, often require progress payments as each stage of construction is completed, meaning the buyer begins making loan repayments before moving in.

If your purchase involves progress payments, the lender structures the loan as a construction loan with an interest-only period during the build phase. You pay interest only on the funds drawn down at each stage, with principal and interest repayments commencing once construction is complete. This reduces the cash flow burden during the build but requires disciplined budgeting to ensure you can afford the higher repayments once the interest-only period expires.

Construction loans also require the buyer to engage a building inspector or quantity surveyor to verify that each stage is complete before the lender releases the next progress payment. If the builder delays a stage or fails an inspection, the lender may withhold funds, creating disputes between the buyer, builder, and lender. Buyers should factor inspection costs of $500 to $1,500 per stage into their settlement budget.

For buyers using the First Home Super Saver Scheme to fund their deposit, the ATO determination must be obtained before the contract is signed, not at settlement. If you have been contributing to super throughout the construction period with the intention of withdrawing under the scheme, you must apply for the determination well in advance of settlement to avoid delays. The $50,000 lifetime cap applies across all financial years, and contributions must be voluntary to be eligible for release.
