Your lender releases construction funds in stages, not upfront. Each release depends on you meeting specific compliance conditions tied to council approvals, builder documentation, and progress inspections. Miss one requirement and the next payment stalls, which can stop your build.
How Construction Draws Actually Get Released
Lenders release funds progressively as your build reaches defined stages. You submit evidence that each stage is complete, the lender arranges a progress inspection, and once satisfied, they release the next portion of the loan amount. Between draws, you only pay interest on what's been released so far, not the full approved sum.
Consider a couple building in Modbury who had council approval and a fixed price building contract with a registered builder. Their lender required copies of the stamped council plans, proof of building insurance, and a signed construction draw schedule before settlement. They provided everything except the final insurance certificate, which delayed their first drawdown by three weeks. Their builder had already ordered materials, expecting payment on the agreed date. The delay created tension and cost the builder holding fees, which nearly derailed the relationship before construction started.
Once that certificate arrived, the lender released the deposit portion to the builder and the project moved forward. The couple then had to submit invoices and stage completion certificates for each subsequent draw, including slab, frame, lockup, fixing, and final completion. Each stage required a fresh inspection and documentation before funds flowed.
What Happens If You Want to Use an Owner Builder Arrangement
Most lenders won't fund owner builder projects at all. Those that do impose stricter conditions, higher interest rates, and lower loan-to-value ratios than they would for a registered builder. You'll need to prove construction experience, provide detailed costings for every trade, and often accept a cost plus contract structure where the lender verifies each invoice before releasing funds to pay sub-contractors like plumbers and electricians.
In our experience, owner builder finance works only when the borrower has genuine trade qualifications and can demonstrate prior builds. Even then, expect to provide more documentation at every stage and accept that some lenders simply won't consider it regardless of your experience. If you're thinking about this route, it's worth understanding the full scope of what lenders require before you commit to the project. You can explore your construction loan options early to see which lenders might support your specific situation.

Fixed Price Contracts Versus Cost Plus Arrangements
A fixed price building contract sets a total build cost upfront. The builder agrees to complete the project for that amount, and the lender structures the progressive drawdown around agreed milestones. You know what you're borrowing, and the lender knows what they're funding.
A cost plus contract means the builder charges for materials and labour as the project progresses, often with a margin added. Lenders treat these differently because the final cost isn't fixed. They'll want to see itemised invoices for every progress payment and may cap the total they'll release based on initial estimates. If costs run over, you'll need to cover the difference or seek additional approval, which isn't certain.
Most lenders prefer fixed price contracts because the risk is clearer. If you're working with a project home builder or a custom design builder in Modbury, confirm which contract type they use and check with your lender before signing. Some lenders won't touch cost plus arrangements at all.
Meeting Council and Development Approval Conditions
Your lender will ask for proof of council approval before releasing any construction funds. That means a stamped development application showing the build is approved, plus any conditions the council has imposed. If the council requires specific drainage work, boundary setbacks, or heritage considerations, your lender will want evidence those conditions are either met or scheduled.
In Modbury, where some blocks sit in areas with specific stormwater or bushfire management overlays, council conditions can add steps to the approval process. Your builder should handle most of this, but the lender will still want copies of the final signed-off plans and any compliance certificates before the first draw. If you're buying a land and construction package or a land and build loan, the developer may have already secured some approvals, but you'll still need to confirm what's in place and what's outstanding.
The Role of Progress Inspections Between Payments
After you submit evidence that a stage is complete, the lender sends a valuer or building inspector to verify the work. They check that the slab is poured, the frame is up, or the roof is on, depending on which stage you're claiming. If the inspection confirms progress matches your claim, the lender releases the next payment. If not, the payment holds until the issue is resolved.
These inspections aren't negotiable. Even if your builder confirms the stage is done, the lender won't release funds without their own verification. The inspection usually costs between a few hundred dollars per visit, and that cost comes out of your loan or your pocket depending on how your lender structures fees. Some lenders charge a Progressive Drawing Fee each time they process a drawdown, which can add up across five or six stages.
We regularly see delays when builders and borrowers assume the inspection is a formality. If the valuer identifies incomplete work or variations from the approved plans, the draw won't proceed until it's fixed. That can leave you covering costs in the meantime or scrambling to get the builder back on site.
Why Timing Conditions in Your Loan Approval Matter
Most construction loan approvals require you to commence building within a set period from the approval date, often six months. If you don't start within that window, the approval lapses and you'll need to reapply. Rates, lending policies, and your financial situation may have changed by then, so there's no certainty you'll get the same terms again.
If you're still finalising council plans or waiting on a builder to lock in a start date, make sure your lender knows. Some will extend the commencement deadline if you can show genuine progress toward starting. Others won't. If you're arranging home loans or construction funding in Modbury and you know your build timeline is tight, raise it upfront so the approval conditions reflect reality.
How Interest Charges Work During Construction
During the build, you only pay interest on the amount the lender has drawn down so far. If they've released $150,000 of a $400,000 loan, you're charged interest on $150,000, not the full amount. That's one advantage of construction funding compared to borrowing the full sum upfront.
Most lenders offer interest-only repayment options during construction, meaning you're not paying down principal while the build is underway. Once construction finishes and you move into a standard home loan structure, repayments shift to principal and interest unless you arrange otherwise. Some lenders automatically convert the loan to a construction to permanent loan at completion, while others require a new application. Know which applies to your situation before you start.
If your build drags on longer than expected, you'll be paying interest-only for a longer period, which can add up. Budget for that possibility, especially if council approvals or builder delays push your completion date out.

Frequently Asked Questions
How do lenders release construction loan funds?
Lenders release funds progressively as your build reaches defined stages like slab, frame, and lockup. Each release requires evidence of stage completion, a progress inspection, and approval before the next payment flows.
What happens if I miss a compliance condition during my build?
If you don't meet a required condition, such as providing council approval or insurance certificates, the lender will hold the next drawdown until you fix it. That can delay payments to your builder and stall the project.
Can I use an owner builder arrangement with a construction loan?
Most lenders won't fund owner builder projects. Those that do require proof of construction experience, detailed costings for every trade, and often impose higher rates and stricter documentation at each stage.
Do I pay interest on the full loan amount during construction?
No, you only pay interest on the amount the lender has drawn down so far. Most lenders offer interest-only repayments during the build, with principal and interest repayments starting once construction completes.
What is a progress inspection and when does it happen?
A progress inspection occurs after you claim a construction stage is complete. The lender sends a valuer or inspector to verify the work matches your claim before releasing the next payment.
