Construction loan settlement works differently to a standard home purchase because funds are released progressively as your build advances, not as a single payment at settlement.
If you're building in Castle Hill, you're likely dealing with sloping blocks or bushfire-prone land zones that can add stages to your build timeline. Understanding how settlement and drawdowns connect helps you plan cash flow and avoid delays when your builder requests payment.
How Construction Loan Settlement Differs from Standard Home Loan Settlement
With a construction loan, settlement happens at the start of your build, not at completion. The lender assesses your application, values the land and proposed dwelling, and approves a total loan amount. Once contracts are signed and conditions are met, the first drawdown is released, usually to purchase the land or pay a deposit to your builder. You don't receive the full loan amount upfront. Instead, funds are released in stages as construction progresses, with each payment tied to a completed milestone verified by an independent inspection.
Consider someone building a custom home on a 650-square-metre block near Excelsior Reserve. They've secured council approval and signed a fixed price building contract with a registered builder for $850,000, plus they're purchasing the land for $900,000. At settlement, the lender releases $900,000 to cover the land purchase. The construction component remains undrawn until the slab is poured. After the builder completes the base stage and submits an invoice, the lender arranges a progress inspection. Once the inspector confirms the work matches the stage description, the lender releases the next portion, perhaps $170,000, directly to the builder. This cycle repeats through frame, lockup, fixing, and practical completion.
Between drawdowns, you only pay interest on the amount already released. If $900,000 has been drawn for land and $170,000 for the slab, you're charged interest on $1,070,000, not the full $1,750,000 loan amount. Most lenders offer interest-only repayment options during construction, switching to principal and interest once the build is finished and you move in.

What Happens at Initial Settlement
Initial settlement is when your loan is formally established and the first funds are released. The lender prepares settlement documents, registers security over the land, and transfers the initial drawdown to complete the land purchase or pay the builder's deposit under your construction contract. You'll sign loan documents, provide evidence of insurance, and confirm that all pre-settlement conditions have been cleared, including council approval and a satisfactory valuation.
Castle Hill builds often involve a development application for sloping sites or heritage overlays near Old Castle Hill Road. If council approval is delayed, settlement is delayed. Lenders require a stamped DA and building approval before they release funds. Once those are in place and your builder confirms a start date, the lender books settlement. On settlement day, the conveyancer or solicitor handles the land transfer, the lender disburses the funds, and your construction loan becomes active.
From that point, you'll receive a loan account statement showing the drawn balance and interest accruing daily. Your first repayment, covering interest only, is typically due within the first month. As each stage is completed and funds are drawn, your balance increases and so does your interest cost.
The Progressive Drawdown Process and Progress Inspections
Drawdowns are tied to a progress payment schedule agreed between you, your builder, and your lender. Most fixed price contracts use a five or six-stage schedule: base, frame, lockup, fixing, practical completion, and sometimes final completion after defects are resolved. Each stage has a payment percentage. The builder invoices you when a stage is done, you forward the invoice to your lender, and the lender orders a progress inspection.
An independent inspector, often a quantity surveyor or registered builder, visits the site and confirms the stage is complete to the standard described in the contract. If the work matches the invoice, the inspector approves the draw. The lender then releases the funds, usually within a few business days, directly into the builder's account. Most lenders charge a Progressive Drawing Fee for each inspection, typically between $300 and $400 per drawdown, though some roll this into the loan or cap the total number of free inspections.
In areas like Castle Hill, where building activity is steady and inspectors are in demand, it's worth staying on top of timing. If your builder finishes the frame stage on a Friday and you submit the invoice that afternoon, the inspection might not happen until midweek, and funds might not land until the following week. Builders often build a buffer into their schedules, but if multiple stages are delayed, it can push out your completion date and extend the period you're paying interest without being able to move in.
Interest Costs During Construction and How They're Calculated
You only pay interest on the amount drawn down at any given time. If your total construction loan is approved for $1,750,000 but only $1,070,000 has been released, interest is calculated daily on that lower figure. The interest rate applied is usually variable unless you've locked in a fixed rate before the first drawdown, which some lenders allow on the construction component once building starts.
Because interest accrues daily and compounds monthly, even small delays in drawdowns or a stretched construction timeline can add up. A build scheduled for eight months that stretches to twelve means four extra months of interest-only payments. If you're paying interest on $1,400,000 at a variable rate for an additional four months, that's several thousand dollars in extra interest before you even make a principal repayment. Some borrowers choose to make additional payments during construction to reduce the balance and limit interest, though this depends on your loan terms and whether your lender allows it.
What Happens at Final Completion and Transition to Principal and Interest
Once your builder reaches practical completion and you've moved in or received the final occupation certificate, the loan transitions from construction to a standard home loan. The lender conducts a final valuation to confirm the property is complete and matches the approved plans. If everything is in order, the loan converts to principal and interest repayments, and your repayment amount increases to start paying down the loan amount over the remaining term.
Some lenders allow you to fix the interest rate at this point if you didn't do so earlier. Others offer a split, where part of the loan is fixed and part remains variable. The shift from interest-only to principal and interest can be significant, sometimes increasing your monthly repayment by 30 to 40 per cent depending on the loan size and interest rate, so it's worth building that into your budget from the beginning.

Frequently Asked Questions
How does construction loan settlement differ from a standard home loan settlement?
Construction loan settlement happens at the start of your build, not at completion. The lender releases funds progressively as each stage is finished and verified by an independent inspector, rather than providing the full loan amount upfront.
Do I pay interest on the full loan amount during construction?
No, you only pay interest on the amount that has been drawn down at any point in time. If only the land purchase and base stage have been funded, interest is charged on that portion, not the total approved loan amount.
What is a progress inspection and why is it required?
A progress inspection is an independent assessment of your build to confirm that a construction stage is complete before the lender releases the next payment. Most lenders charge a fee for each inspection, typically between $300 and $400.
When does my loan convert from interest-only to principal and interest?
Your loan converts to principal and interest repayments once your build reaches practical completion and you receive an occupation certificate. The lender conducts a final valuation and then adjusts your repayments to include both interest and principal.
What approvals do I need before construction loan settlement?
You need council approval, including a development application if required, and building approval before the lender will release funds. A satisfactory valuation and signed fixed price building contract with a registered builder are also required.
