Proven Tips to Finance an Off-the-Plan Purchase in Perth

Off-the-plan purchases in Perth require a different financing approach to established property.

Most buyers sign contracts 12 to 24 months before settlement, and your financial position, the lender's credit policy, and even the property's valuation can shift substantially during that window. A home loan pre-approval locked in at contract stage does not guarantee the same terms will still be available when the property reaches practical completion. Lenders reassess your application closer to settlement, and if your income has dropped, your debts have increased, or the completed property values below the contract price, your funding can fall through.

The most useful step you can take is to structure your application so it survives a second round of credit assessment 18 months later.

What Lenders Reassess at Settlement

Lenders reconfirm your income, liabilities, and employment status within 90 days of settlement. They also commission a formal valuation of the completed property. If the valuation comes in below the contract price, the loan amount is recalculated based on the lower figure, and you will need to make up the shortfall in cash. Consider a buyer in Scarborough who signs a contract for a two-bedroom apartment priced at $650,000 with a 10 per cent deposit. At settlement, the property values at $620,000. The lender approves a loan based on the $620,000 valuation, not the $650,000 contract price. The buyer needs to find an additional $30,000 to settle, on top of the original deposit.

Valuation shortfalls are more common in precincts where multiple developments are completing at the same time, particularly if rental yields have softened or sales volumes have increased.

Sunset Clauses and Loan Product Expiry

Most off-the-plan contracts include a sunset clause that allows either party to walk away if the development is not completed by a specified date. Contracts in Western Australia routinely include sunset dates between 24 and 36 months from signing. If the developer invokes the clause, your deposit is returned, but your pre-approval will have expired. If you have relied on a state duty concession or an FHOG eligibility window that has since closed, you may not be able to replicate the same financial position on a replacement purchase.

Fixed rate offers expire too. If you locked in a fixed rate at application and the development is delayed, that rate may no longer be available when you settle. Most lenders hold fixed rates for a maximum of 90 days from the expected settlement date. If completion is pushed back by six months, you will need to reapply at current rates.

Using the Australian Government 5% Deposit Scheme for Off-the-Plan

The Australian Government 5% Deposit Scheme can be used for off-the-plan purchases, but both the contract price and the valuation at settlement must fall within the applicable price cap. In Western Australia, the price cap is $850,000 in capital cities and regional centres and $600,000 in other areas. Buyers in Perth purchasing an off-the-plan apartment at $840,000 meet the contract price requirement, but if the property values at $870,000 at completion, the scheme cannot be used. You would need to increase your deposit to 20 per cent or pay Lenders Mortgage Insurance.

The scheme also requires you to live in the property as your principal place of residence. If your circumstances change during construction and you can no longer occupy the property, you will not meet the scheme's eligibility criteria at settlement. Notify your lender immediately if your occupancy intention changes, as it affects both your loan structure and the availability of the guarantee.

Off-the-Plan Stamp Duty Concessions in Western Australia

Western Australia offers an off-the-plan duty concession for strata, survey-strata, or community title dwellings purchased before construction is complete or while construction is underway. For pre-construction contracts, a 100 per cent concession capped at $50,000 applies on dwellings valued up to $800,000, reducing proportionally to 50 per cent for dwellings valued between $800,001 and $899,999, and a 50 per cent concession applies on dwellings valued at $900,000 or more. The concession runs until 30 June 2028 and applies regardless of whether you are a first home buyer.

In a scenario where you purchase a two-bedroom apartment in Applecross under a pre-construction contract for $780,000, the full 100 per cent concession applies, reducing your duty liability to nil on the capped amount. If the same apartment were purchased for $850,000, the 50 per cent concession applies, and you pay duty on half the dutiable value. The concession is calculated on the dwelling's dutiable value at the contract date, not the completed value.

Split Loan Structures for Long Settlement Periods

A split loan allows you to fix part of your loan and keep part variable. For off-the-plan purchases, this structure gives you interest rate protection on the fixed portion while retaining flexibility on the variable portion if you need to adjust repayments or make lump sum contributions during the construction period. Many buyers split 50 per cent fixed and 50 per cent variable, but the ratio should reflect your risk tolerance and cash flow position over the expected holding period.

If you fix 70 per cent of a $585,000 loan at settlement and variable rates drop by 0.5 per cent within 12 months, the variable portion benefits immediately. The fixed portion remains unchanged, but you have avoided locking your entire loan at a rate that turned out to be higher than necessary. Lenders allow splits across two, three, or even four separate loan accounts, each with different terms and features.

Linking an Offset Account Before Settlement

Some lenders allow you to open an offset account and link it to your loan before settlement, so any funds you deposit during the construction period offset interest once the loan activates. This is useful if you receive a bonus, tax refund, or additional savings during the 12 to 18 months between contract and completion. The offset does not reduce the loan balance, but it reduces the interest charged on the outstanding amount from day one.

You cannot offset interest that has not yet accrued, so the account only provides value after your loan settles. Check whether your lender charges a monthly account fee for the offset, as some will apply the fee even during the pre-settlement period when the loan has not yet drawn down.

Why Pre-Approval Alone Does Not Secure Your Loan

Pre-approval confirms a lender is willing to lend to you based on the information you have provided at a point in time. It does not lock in the loan amount, the interest rate, or the product features beyond the validity period stated in your approval letter. For off-the-plan purchases, pre-approval is a starting point, not a finish line. Lenders will reassess your application closer to settlement, and if your financial position has deteriorated or the property no longer meets their security requirements, they can withdraw the offer.

Maintain stable employment, avoid taking on new debt, and do not change your income structure between contract and settlement. If you move from full-time employment to contract work, or if you increase your credit card limit, the lender may recalculate your borrowing capacity and reduce the approved loan amount. Keep your broker informed of any changes to your circumstances as soon as they occur, so your loan structure can be adjusted before it becomes a problem at settlement.

Construction Loans Versus Standard Home Loans for Off-the-Plan

Some off-the-plan purchases require a construction loan if you are contracting directly with a builder on a strata lot, while others settle as a standard home loan if you are purchasing a completed or near-completed unit from a developer. The distinction depends on how the contract is structured and when progress payments are required. If the contract includes stage-based progress payments during construction, you will need a construction loan with multiple drawdowns. If you pay a deposit at contract and the balance at settlement, a standard home loan applies.

Construction loans are more complex to administer and often come with higher interest rates during the construction phase. Some lenders charge interest on drawn funds only, while others require interest-only repayments on the full approved amount from the first drawdown. Clarify the repayment structure before you sign the loan contract, as it affects your cash flow throughout the build.
