Beginner's Guide to Construction Loan Monitoring

Construction loan monitoring is the process lenders use to confirm building work is complete before releasing funds at each stage of your build.

When you're building a home in Western Australia, your lender doesn't hand over the full loan amount upfront. Funds are released in stages as construction progresses, and an independent inspector visits the site to verify each stage is finished before the next payment is approved. This protects both you and the lender, but it also means your builder's payment schedule needs to align with your lender's drawdown process. Understanding how monitoring works prevents payment delays that can stall your build or create tension with your builder.

Who Conducts the Progress Inspections

Most lenders engage a third-party valuation company to carry out progress inspections throughout your build. The inspector visits your site at each drawdown stage, checks the work against the building contract and council plans, and prepares a report confirming whether the stage is complete. Your lender reviews this report before releasing funds. Some lenders conduct inspections in-house, but the process remains the same. The inspector is not there to assess quality in detail, they verify that the stage described in your contract has been reached and that the property value supports the amount being drawn.

Consider a Navy member posted to HMAS Stirling who's building on a block in Mandurah. The construction contract lists five stages: base, frame, lockup, fixing, and practical completion. At frame stage, the builder requests a drawdown. The lender's inspector visits, confirms the frame and roof are up, and reports back. The lender releases the funds directly to the builder within a few days. If the inspector finds the frame incomplete or identifies a discrepancy between the contract and the work on site, the drawdown is delayed until the issue is resolved.

How the Progressive Drawing Fee Works

Lenders charge a fee each time they arrange an inspection and release funds during your build. This is called a progressive drawing fee or progress payment fee, and it typically ranges from $150 to $400 per drawdown depending on the lender and location. If your build has five stages, you'll pay this fee five times. Some lenders cap the total fees or offer a flat rate for all inspections, so it's worth comparing this cost when you're choosing a lender for your construction loan.

These fees cover the cost of the independent inspector, the valuation report, and the lender's administration. They're separate from your loan amount and are usually deducted from each drawdown or paid upfront. In regional WA, where travel costs are higher, some lenders add a surcharge for inspections outside the Perth metro area. If you're building in a location like Geraldton or Broome, confirm the inspection fees before you commit to a lender.

Fixed Price Contracts and the Progress Payment Schedule

A fixed price building contract sets out the total cost of your build and breaks it down into stages with a dollar amount assigned to each stage. Your lender uses this schedule to determine how much to release at each drawdown. The schedule in your contract must match the stages your lender will fund, otherwise you'll face delays or disputes.

In WA, most volume builders and project home builders use fixed price contracts with a standard five-stage payment schedule: deposit, base, frame, lockup, fixing, and final payment at practical completion. Custom builders sometimes use a cost-plus contract, where you pay for materials and labour as invoices are submitted. Lenders are more cautious with cost-plus contracts because the final cost isn't locked in, and monitoring becomes more involved. If you're considering a cost-plus arrangement, check that your lender will support it and understand how drawdowns will be managed. Most ADF members building for the first time will be working with a registered builder under a fixed price contract, which gives both you and your lender certainty around costs and timing.

Interest Charges During Construction

During the construction phase, you only pay interest on the amount drawn down, not the full loan amount. As each stage is completed and funds are released, your interest charges increase. This is one of the main differences between a construction loan and a standard home loan. Once the build is finished, the loan typically converts to a standard principal-and-interest or interest-only loan, depending on what you've arranged with your lender.

As an example, an Air Force member building in Bullsbrook arranges a construction loan for $550,000. At base stage, $110,000 is drawn down. Interest is charged only on that $110,000 until the next drawdown. By lockup stage, a total of $330,000 has been released, and interest is now calculated on that amount. This structure reduces your interest costs during the build, but you need to budget for increasing repayments as the loan balance grows. Most lenders offer interest-only repayment options during construction, which keeps your repayments lower while the build is underway.

What Happens If a Stage Fails Inspection

If the inspector determines that a stage is incomplete or that the work doesn't match the contract, the lender will not release the drawdown until the issue is rectified. This can delay payment to your builder and may stall progress on site. Common reasons for a failed inspection include incomplete work, variations that haven't been documented, or discrepancies between the council-approved plans and what's been built.

When this happens, your builder will need to finish the outstanding work or provide documentation to explain the variation. The lender will then arrange a re-inspection, which may incur an additional fee. To avoid this, make sure your builder understands the lender's requirements before construction starts and that any variations to the original plans are documented and approved by both the lender and your local council. If you're using a Defence-friendly lender with experience in construction finance, they'll usually flag potential issues early and work with you and your builder to keep things moving.

How Long Each Drawdown Takes

From the time your builder requests a drawdown to when funds are released typically takes between five and ten business days. Your builder notifies you that a stage is complete, you notify your lender, the lender arranges the inspection, the inspector visits and submits a report, the lender reviews the report, and then the funds are transferred. If you're posted interstate or deployed, this process can be managed remotely, but you need to set up clear communication with both your builder and your lender to avoid delays.

Some lenders allow you to request inspections online or through a mobile app, which speeds up the process. Others require a phone call or email. If your builder operates on tight cash flow and relies on prompt payment at each stage, delays in the drawdown process can create tension. Discuss the expected timeline with your builder before you commence building and make sure they understand that payment is dependent on the lender's inspection process, not just the completion of work on site.

Owner Builder Finance and Monitoring Requirements

If you're acting as an owner builder in WA, construction loan monitoring becomes more detailed. Lenders view owner builder projects as higher risk because you're managing the build yourself rather than using a licensed builder. Most lenders require additional inspections, more frequent reporting, and evidence that subcontractors and suppliers have been paid before releasing each drawdown. Some lenders won't offer owner builder finance at all.

If you're an ADF member considering an owner builder project, expect to provide invoices from plumbers, electricians, and other subcontractors at each stage, along with statutory declarations confirming payment. The lender's inspector will verify that work has been completed and that there are no outstanding debts that could result in liens on the property. This process takes longer and costs more than a standard construction loan, but it's the only way most lenders will support an owner builder project. Make sure you understand these requirements before you commit to building without a registered builder.

Choosing a Lender With Construction Loan Experience

Not all lenders handle construction loans the same way. Some have dedicated construction teams and streamlined monitoring processes, while others treat construction finance as a secondary product and outsource most of the work. Lenders who specialise in construction finance tend to process drawdowns faster, charge lower inspection fees, and offer more flexibility if issues arise on site. If you're building in a regional area or using a custom builder, working with a lender experienced in construction finance will save you time and frustration.

ADF members building in WA should also consider lenders who understand Defence employment. Frequent postings, deployments, and irregular income patterns can complicate a construction loan application, and lenders who work regularly with ADF clients are more likely to accommodate these factors. A mortgage broker who specialises in Defence finance can connect you with lenders who offer both construction loan expertise and ADF-friendly policies, including LMI waivers and flexible serviceability assessments.
