Your lender doesn't hand over the full loan amount on day one.
When you take out construction finance, the funds release in stages as your build progresses. This process, called construction loan monitoring, determines when money flows from your lender to your builder, and it directly affects your building schedule and what you pay in interest along the way.
How Progressive Drawdowns Actually Work
The lender releases funds based on a progress payment schedule that matches specific stages of your build. You only pay interest on the amount drawn down at any point, not the full loan amount. Consider someone building in Lakelands who's approved for $550,000 in construction funding. After the slab goes down, they might draw $120,000. Until the frame goes up and the next stage completes, they're only paying interest on that $120,000, not the full amount.
Most construction loans work on a four to six stage drawdown. Common stages include site preparation and slab, frame and roof, lockup (windows and doors fitted), fixing (internal fit-out), and practical completion. Your building contract should match these stages, and your lender will want to see that alignment before settlement.
The Progress Inspection That Delays or Releases Payment
Before each drawdown, the lender arranges a progress inspection. A qualified building inspector visits your site, confirms the work matches the claimed stage, checks for quality construction standards, and reports back to the lender. Only after the lender receives and reviews that report does the money release.
In our experience working with builds around Halls Head and Meadow Springs, this inspection step adds anywhere from three to seven days between your builder requesting payment and actually receiving it. Your builder knows this timing exists, but if you're coordinating with plumbers or electricians separately as an owner builder, you need to factor it into your payment schedules with sub-contractors.
Some lenders charge a Progressive Drawing Fee for each inspection and drawdown, typically between $300 and $500 per stage. That cost sits separate from your loan amount and comes out of your available funds or gets added to what you owe.
What Happens When the Inspector Finds Issues
If the inspector identifies incomplete work or quality concerns at a claimed stage, the lender holds the payment until those items get rectified. The builder fixes the issues, the inspector returns, and only then does the drawdown proceed. This creates delays that push out your building timeline and can strain relationships between you and your registered builder.
As an example, someone building a custom home in Falcon had their frame stage drawdown held for two weeks because temporary bracing wasn't properly secured and the inspector noted concerns about wind loading compliance. The builder rectified it within days, but the re-inspection took another week to schedule. That delay meant the electricians booked for rough-in had to reschedule, which pushed the whole job back three weeks. Your building contract might include provisions for these delays, but understanding the monitoring process helps you ask the right questions before you commence building.
Fixed Price Building Contracts and Cost Plus: Different Monitoring Approaches
With a fixed price building contract, your builder quotes a total price and the progress payment schedule divides that amount across stages. The monitoring process confirms each stage is complete, and the predetermined amount releases. With a cost plus contract, you're funding actual costs as they occur, plus the builder's margin. The inspector still confirms work completion, but the drawdown amount varies based on what was actually spent.
Cost plus arrangements require closer monitoring because there's no fixed ceiling on what each stage might cost. Most lenders prefer fixed price contracts for standard construction to permanent loan products because the risk is clearer. If you're pursuing cost plus, expect more documentation requirements and potentially a larger deposit.
The Timeline Between Council Approval and First Drawdown
You can't draw funds until council approval comes through and your builder is ready to start. Your loan approval might specify you need to commence building within a set period from the Disclosure Date, often six months. If council plans take longer than expected or your builder's schedule pushes out, you might need to extend your approval, which can mean re-assessment if interest rates or your financial situation has changed.
In Mandurah, where land and construction packages are common particularly around new estates like Lakelands, the development application and council approval process typically runs eight to twelve weeks. Factor that into your planning if you're trying to coordinate a settlement on your current home with the start of your new build.
What This Means for Your Interest Payments
Because you only pay interest on the amount drawn down, your repayments start small and increase as the build progresses. Most construction funding comes with interest-only repayment options during the building phase, which keeps your payments lower while you're potentially paying rent or a mortgage elsewhere. Once you reach practical completion and the loan converts to a standard home loan, you switch to principal and interest repayments on the full amount.
Understanding the progressive drawdown structure helps you budget for those increasing payments. If you're building while renting and your current rent is $450 per week, you need to plan for construction loan interest that might start at $200 per week and build to $800 per week by completion, all while still covering that rent.
If you're planning a build in Mandurah and want to understand how the monitoring process will affect your specific project timeline and costs, call one of our team or book an appointment at a time that works for you. We'll walk through your building contract, explain what each lender requires for inspections, and help you set up a drawdown structure that matches how your builder actually works.
Frequently Asked Questions
How long does each progress inspection take before funds release?
The inspection itself typically occurs within a few days of the builder's drawdown request, but the full process from request to funds releasing usually takes three to seven days. This includes the inspector visiting the site, preparing their report, the lender reviewing it, and processing the payment.
Do I pay interest on the full loan amount during construction?
No, you only pay interest on the amount drawn down at each stage. If you've drawn $150,000 from a $500,000 construction loan, you're only paying interest on the $150,000 until the next drawdown occurs.
What happens if the building inspector finds problems?
The lender holds the drawdown payment until the builder rectifies the identified issues. The inspector returns for a re-inspection, and only after receiving a satisfactory report does the lender release the funds, which can delay your building timeline by one to three weeks.
What are Progressive Drawing Fees and who pays them?
These are fees charged by the lender for each progress inspection and drawdown, typically $300 to $500 per stage. They come out of your available funds or get added to your loan balance, separate from the actual construction costs.
How does construction loan monitoring differ between fixed price and cost plus contracts?
With fixed price contracts, predetermined amounts release at each completed stage. With cost plus contracts, the drawdown amount varies based on actual costs incurred, requiring more detailed documentation and closer monitoring of expenses at each stage.
