Managing Progressive Drawdowns Without Overpaying Interest
You only pay interest on the funds drawn down at each stage of your build, not the full loan amount from day one. That means your interest costs start low when only the land or initial slab payment has been made, then increase as more progress payments are released. The key is making sure each drawdown matches what's actually been completed on site, so you're not paying interest on work that hasn't happened yet.
Consider a couple building in Rockingham who arranged their construction finance with five scheduled drawdowns: land settlement, base stage, frame stage, lock-up, and final completion. After the frame stage inspection, the builder requested the lock-up payment early due to materials being delivered ahead of schedule. Because the inspection hadn't confirmed lock-up stage completion, the broker held the drawdown until the certifier signed off. That two-week delay saved around three months of unnecessary interest on funds that would have sat unused.
Most lenders require an independent inspection before releasing each progress payment. The inspector confirms that the stage is complete and meets the contract specifications, then submits a report to the lender. Once approved, funds are transferred directly to the builder. This process typically takes three to five business days from inspection to payment, so builders usually request the inspection a week before they need the funds. If you're coordinating this yourself rather than through a broker, keep a calendar of expected completion dates and book inspections in advance to avoid delays that can frustrate your builder or hold up subcontractors waiting for payment.
What Happens When a Progress Payment Gets Held Up
A delayed progress payment can stop work on site almost immediately. Builders often schedule subcontractors around expected payment dates, and if funds don't arrive on time, those subcontractors may move to other jobs. Getting them back can push your timeline out by weeks, particularly in Rockingham where demand for plumbers and electricians has been consistent due to ongoing residential development near the foreshore and Safety Bay Road corridor.
Payment delays usually happen for one of three reasons: the inspection report identifies incomplete or defective work, the builder hasn't provided updated invoices or receipts to match the claimed stage, or there's a mismatch between the contract's progress payment schedule and what the lender agreed to fund at each stage. That last issue is surprisingly common when buyers arrange their own construction loans without checking that the builder's payment schedule aligns with the lender's drawdown structure. Some builders work on a percentage basis, others use fixed stage amounts, and if those don't match what the lender will release, you'll need to either renegotiate the contract or cover the gap yourself.
If a payment does get held up, contact your broker and your builder immediately. The broker can often clarify what the lender needs to release the funds, whether that's a revised inspection report, additional documentation, or confirmation from the certifier. The builder needs to know why the delay is happening so they can decide whether to continue work at risk or pause until funds are confirmed. Leaving either party in the dark turns a small administrative issue into a relationship problem that can sour the rest of your build.

Fixed Price Contracts and Cost Plus Contracts
A fixed price building contract sets a total build cost upfront, and the builder is responsible for completing the work within that amount. A cost plus contract charges you the actual cost of labour and materials, plus a builder's margin, which means the final price isn't locked in until the build is finished. Most lenders in Australia prefer fixed price contracts because the loan amount can be set with certainty, and there's less risk of cost blowouts that leave the borrower unable to complete the project.
If you're considering a cost plus contract, expect more scrutiny during the construction loan application. Lenders may require a detailed cost estimate with itemised allowances for materials, a cap on the builder's margin, and a larger contingency buffer, often 15% to 20% rather than the standard 5% to 10% used with fixed price contracts. You'll also need to provide updated invoices and receipts at each drawdown stage to justify the amount being claimed, which adds administrative work and can slow down payment approvals if documentation isn't organised.
Fixed price contracts offer more certainty, but only if the contract is written properly. Make sure the contract includes a clear progress payment schedule with defined stages, specifies what's included in the build and what's a variation, and lists a realistic timeframe for completion. If the contract says you must commence building within a set period from the disclosure date, make sure your council approval and development application are already in progress when you sign. Missing that deadline can void the price guarantee and force a renegotiation at current rates, which can be thousands of dollars higher if material costs have moved.
How Construction to Permanent Loans Work in Practice
A construction to permanent loan starts as a construction facility with progressive drawdowns during the build, then converts to a standard home loan once the build is complete and you've moved in. During construction, you make interest-only repayments on the amount drawn down. After final completion, the loan converts to principal and interest repayments based on the full loan amount, and you can choose a variable or fixed interest rate at that point.
This structure avoids the need to refinance after the build is finished, which saves on application fees, valuation costs, and settlement charges. It also means you're not trying to refinance in a market where your property may not yet have reached its completed value, particularly if you've built in a new estate where comparable sales are still establishing. In Rockingham, estates like Secret Harbour and Baldivis have seen strong price growth once infrastructure and amenities are in place, but in the first 12 months after completion, valuations can be conservative if there aren't enough recent sales to support your build cost.
Most construction to permanent loans allow you to lock in an interest rate for the ongoing loan before construction is complete, usually within 90 days of final drawdown. This can be useful if rates are rising, but it also means you're committing to a fixed rate or variable rate without knowing exactly when final completion will happen. If your build runs over schedule and you've locked in a fixed rate, you may be stuck with that rate even if variable rates have dropped by the time you move in. Discuss your rate lock options with your broker once you're past lock-up stage and have a confirmed completion date from your builder.
Progressive Drawing Fees and How They Add Up
Lenders charge a fee each time they process a progress payment, typically called a progressive drawing fee or progress inspection fee. This fee covers the cost of arranging the independent inspection, processing the drawdown, and transferring funds to the builder. Fees vary by lender but generally sit between $200 and $400 per drawdown.
With a standard five-stage build, you're looking at around $1,000 to $2,000 in progressive drawing fees across the entire construction period. Some lenders charge a flat fee per drawdown, others charge a percentage of the amount drawn, and a few include a set number of drawdowns in the loan package then charge for any additional inspections. If your build requires more than five or six drawdowns, either because of a complex custom design or because the builder's payment schedule is broken into smaller stages, those fees can climb quickly.
These fees are usually added to your loan balance rather than paid upfront, which means you'll pay interest on them over the life of the loan. That's not a major issue for a few hundred dollars per drawdown, but it's worth confirming the fee structure during your construction loan application so you're not surprised when the fees appear on your loan statements. Some brokers can negotiate fee waivers or reductions as part of the overall loan package, particularly if you're borrowing a larger loan amount or bringing other business to the lender.
Owner Builder Finance and Why It's Harder to Arrange
Owner builder finance is available, but most mainstream lenders won't touch it. Building your own home without a registered builder increases the lender's risk significantly, because there's no builder's warranty insurance to cover defects or incomplete work, and no licensed builder accountable for meeting Australian building standards. Lenders that do offer owner builder finance usually require a larger deposit, charge a higher interest rate, and cap the loan amount at 60% to 70% of the project's completed value.
If you're considering an owner builder project in Rockingham, expect to provide detailed council plans, a fixed price contract with subcontractors for each stage, proof of your building qualifications or relevant experience, and evidence that you've arranged builder's insurance independently. The lender will also want a detailed construction draw schedule with milestones that match how subcontractors will be paid, and they may require more frequent progress inspections to confirm work quality at each stage.
In most cases, working with a registered builder and arranging standard construction finance will cost you less overall once you factor in the higher interest rate, additional inspections, and the time required to manage subcontractors yourself. If your reason for going owner builder is to save on the builder's margin, run the numbers carefully to make sure the savings outweigh the additional holding costs and financing charges.
Land and Construction Packages Versus Buying Land First
A land and construction package bundles the land purchase and build contract together, often with a single settlement date once the home is complete. This approach can reduce upfront costs because you're not paying interest on the land while you're still finalising your build plans, and some developers offer incentives like reduced land prices or contributed upgrades when you buy a house and land package from their preferred builders.
The downside is less flexibility. You're typically limited to a few builders and a set range of home designs, and the land price may be inflated to cover the developer's incentives. In Rockingham, several estates near Lakelands and Baldivis offer house and land packages, but it's worth comparing the package price against buying suitable land separately and engaging your own builder. In some cases, buying land first gives you more time to save a larger deposit, shop around for construction finance, and lock in a builder during a quieter period when pricing is more competitive.
If you buy the land first, you'll need to start making repayments on the land loan immediately, even if you're not ready to start building. Some buyers use an interest-only repayment option on the land loan to keep costs down while they finalise plans and secure council approval. Once construction starts, the land loan and construction facility can often be consolidated into a single construction to permanent loan, which simplifies your repayments and keeps all your borrowing with one lender.

Frequently Asked Questions
How do progressive drawdowns work during a construction loan?
You only pay interest on the amount drawn down at each stage of the build, not the full loan amount from day one. Each drawdown is released after an independent inspection confirms the stage is complete, and funds are transferred directly to the builder within three to five business days.
What is the difference between a fixed price contract and a cost plus contract?
A fixed price contract sets a total build cost upfront and the builder completes the work within that amount. A cost plus contract charges the actual cost of labour and materials plus a builder's margin, meaning the final price isn't locked in until the build is finished.
What fees apply to construction loans?
Lenders charge a progressive drawing fee each time they process a progress payment, typically between $200 and $400 per drawdown. With a standard five-stage build, you're looking at around $1,000 to $2,000 in fees across the entire construction period.
Can I get construction finance as an owner builder?
Owner builder finance is available but most mainstream lenders won't offer it. Lenders that do usually require a larger deposit, charge a higher interest rate, and cap the loan amount at 60% to 70% of the project's completed value.
Should I buy land first or choose a house and land package?
A house and land package bundles the land purchase and build together, reducing upfront costs but limiting flexibility. Buying land first gives you more time to save a larger deposit and choose your own builder, but you'll start making land loan repayments immediately.
