Avoid These 7 Construction Loan Settlement Mistakes

Settlement on a construction loan isn't a single event where you collect keys and walk away.

You're settling on the land first, then managing a series of progress payments as your builder completes each stage. Miss a document, underestimate your holding costs, or misunderstand the payment schedule, and you'll either delay your build or scramble to cover shortfalls your lender won't fund.

This guide walks through the specific settlement structure for construction finance in Western Australia, the mistakes that cause delays, and what actually happens at each stage from land settlement through to your final drawdown.

Settling on Land Before Construction Begins

You settle on the land using the first portion of your approved loan, and construction funding remains undrawn until your builder is ready to start.

Consider a buyer purchasing vacant land in Padbury for a land and construction package. They've been approved for a total facility covering both the land purchase and the build. At land settlement, the lender releases funds to cover the land component plus stamp duty and legal costs. The construction portion stays in the loan account, untouched, until the builder has council approval and is ready to pour the slab.

Between land settlement and the first construction drawdown, you're paying interest only on the land amount. That gap can stretch from a few weeks to several months depending on how quickly your builder secures permits and schedules the first stage. If you're also paying rent elsewhere during this period, holding costs add up quickly. Buyers regularly underestimate this gap and find themselves covering dual costs longer than expected.

Your lender will require evidence that council approval is in place and that your building contract is signed before releasing the first construction payment. Without those documents, the construction loan stays frozen regardless of what your builder tells you about start dates.

How the Progressive Drawdown Actually Works

Your lender releases funds in stages as your builder completes predefined milestones, not as a lump sum upfront.

Most lenders in Western Australia tie drawdowns to a fixed price building contract and follow a schedule that looks like this: base stage and frame, lock-up, fixing, and practical completion. Each stage requires a progress inspection by the lender's valuer or an independent inspector before funds are released. Your builder submits a payment claim, the lender arranges the inspection, and once the work is verified, the next drawdown is released directly to the builder.

You don't control the timing of these payments. Your builder does, by completing the work and submitting the claim. If your builder falls behind schedule or fails an inspection due to incomplete work, the drawdown is delayed and so is the payment. That delay can create tension with your builder, but the lender won't release funds until the inspection confirms the stage is done.

Lenders charge a Progressive Drawing Fee each time they release funds, usually between $300 and $400 per drawdown. Across four or five stages, that's an additional $1,500 or more in fees that sit outside your loan amount and need to be paid upfront or added to the loan if the lender allows it.

Interest Charges Start Immediately After Each Drawdown

You begin paying interest on each portion of the construction loan as soon as the lender releases it, not when the build is finished.

In a scenario where the base stage drawdown is $80,000 and the frame stage is another $120,000, you're paying interest on $80,000 from the first drawdown, then on $200,000 after the second. By the time you reach lock-up and fixing stages, you're carrying interest on most of the loan amount while still months away from moving in.

Most construction loans offer interest-only repayment options during the build, which keeps your monthly outgoings lower than a principal and interest loan would. But interest-only still means you're paying interest on every dollar drawn down, and if your build drags out due to weather, supply delays, or builder scheduling, those extra months of interest add up.

Some buyers assume they won't pay anything until the house is finished. That assumption collapses the first time a drawdown hits their loan account and interest starts accruing. If you're budgeting only for rent or your current mortgage during the build, you're underestimating your actual costs.

What Happens If Your Build Goes Over Budget

If your builder claims the project needs more money than the approved loan amount, your lender won't automatically increase your facility.

Cost overruns happen when site conditions are worse than expected, when you make variations to the build, or when your builder underquoted the job. Your lender approved a loan amount based on the contract price and their valuation of the finished home. If that contract price climbs, you'll need to demonstrate that the additional cost is justified and that you can service the higher loan amount.

In our experience, buyers who sign cost plus contracts without a clear cap on expenses face the highest risk of budget blowouts. A cost plus arrangement means you're paying the builder's actual costs plus a margin, and if those costs escalate, you're liable for the difference. Fixed price contracts offer more protection, but even those can include clauses that allow price increases for specific reasons.

If you can't secure additional funding and your builder won't absorb the overrun, the build stalls until the gap is resolved. That might mean finding cash from savings, borrowing against another property, or renegotiating the scope of work with your builder. Lenders won't release the final drawdown until all invoices are settled, so an unresolved shortfall will hold up practical completion and delay your move-in date.

Council Approval and the Commencement Clause

Your building contract likely requires you to commence building within a set period from the disclosure date, and missing that deadline can void the contract or trigger penalty clauses.

Development applications in Western Australia can take anywhere from a few weeks to several months depending on the council, the complexity of the design, and whether you're building in an area with specific planning restrictions. If your approval is delayed and you hit the commencement deadline in your contract, you'll need to negotiate an extension with your builder or risk having the contract cancelled.

Some lenders also impose their own timeframes. If you don't start construction within six or twelve months of land settlement, they may reassess your loan or require updated financials before releasing the first drawdown. That reassessment could uncover changes in your employment, income, or credit profile that affect your ability to proceed.

Buyers in suburbs with heritage overlays or bushfire-prone areas, including parts of the northern coastal corridor, often face longer approval times. If you're building in one of those zones, factor in extra time before assuming your builder can start on schedule.

Settling the Final Drawdown and Converting to Principal and Interest

The final drawdown is released once your builder reaches practical completion and the lender's inspection confirms the home is finished to contract standard.

Practical completion doesn't mean every minor defect is fixed. It means the house is liveable and all major work is done. Your builder will provide a certificate of practical completion, and your lender will arrange a final inspection before releasing the last payment. Once that payment is made, your loan converts from interest-only construction funding to a standard home loan with principal and interest repayments unless you've arranged otherwise.

That conversion can catch buyers off guard if they haven't budgeted for the jump in repayments. Interest-only repayments on a $500,000 loan at current variable rates might sit around $2,000 per month, while principal and interest repayments on the same loan could be closer to $3,200. If you've been managing rent and interest-only payments during the build, suddenly adding an extra $1,200 per month to your budget requires adjustment.

Some lenders allow you to extend the interest-only period after construction is complete, but that's not automatic. If you want that option, discuss it with your broker before settlement rather than assuming it will be available later.

Why a Registered Builder Matters for Loan Approval

Lenders will only release construction funding if your builder is registered and insured, and using an owner builder or unregistered contractor will disqualify you from most construction loan products.

Registration ensures your builder meets minimum standards and carries the required insurance to cover defects and incomplete work. If your builder isn't registered, the lender has no recourse if the build fails, and they won't take that risk. Owner builder finance exists, but it's harder to secure, comes with higher interest rates, and requires you to demonstrate construction experience or project management capability.

If you're planning to act as an owner builder to save on builder's margins, talk to a mortgage broker who understands owner builder finance before you commit. The savings can be real, but the additional scrutiny from lenders and the hands-on management required often make it less viable than buyers expect.
