What are Construction Loan Structures and How They Work

Building a new home in Croydon North means understanding how construction finance is structured before you sign a building contract. Unlike a standard home loan where you receive the full amount upfront, construction funding is released in stages as your build progresses, and you only pay interest on what's been drawn down.

How Construction Finance Differs from Standard Home Loans

Construction finance is released progressively as specific milestones are completed, rather than as a lump sum at settlement. The lender inspects the work at each stage and releases funds directly to your registered builder based on the progress payment schedule outlined in your fixed price building contract. You're charged interest only on the amount drawn down at each stage, which keeps your repayments lower during the build period.

Most lenders offer construction loans as a construction to permanent loan structure, meaning the facility converts to a standard principal and interest loan once your home is complete and you move in. During construction, you typically make interest-only repayments on whatever portion of the loan has been released.

The Standard Five-Stage Drawdown Structure

Most lenders and builders in Victoria use a five-stage progressive drawdown structure tied to physical milestones. The first payment, usually around 5% to 10% of the contract price, is released on the base stage when the concrete slab is poured and cured. The second payment covers the frame stage once the roof frame is erected and secured. The third release happens at lockup when the external walls, windows, and doors are installed. The fourth payment is triggered at fixing stage when internal fittings, cabinetry, and fixtures are installed. The final payment, typically 10% to 15%, is released at practical completion after a final inspection confirms all work is finished to the contract standard.

Each stage triggers a progress inspection by the lender's valuer, which incurs a Progressive Drawing Fee, usually between $150 and $350 per inspection depending on the lender. These fees are typically charged to your loan account rather than paid upfront.

Construction to Permanent Loan Conversion

Once practical completion is confirmed and you've received your occupancy permit from Maroondah City Council, your construction facility converts to a standard home loan. At this point, your repayments shift from interest-only on the drawn amount to principal and interest on the full loan amount. The interest rate may also change if your construction loan interest rate was different to the ongoing variable or fixed rate you selected for the permanent phase.

Some lenders allow you to lock in a fixed rate for the permanent loan phase at the time you apply for construction finance, which can provide certainty if you're concerned about rate movements during your build. Others require you to select your ongoing rate structure closer to completion.

Land and Construction Package Funding

If you're purchasing vacant land and building in Croydon North, lenders can structure your finance as a land and construction package where the land purchase settles first, followed by the construction phase. You'll need to settle on the land before construction can begin, and most lenders require you to commence building within a set period from the land settlement date, usually six to twelve months.

During this gap between land settlement and construction commencement, you'll make repayments on the land component only. Once construction begins, the progressive drawdown structure applies to the building component while you continue servicing the land loan. Both components then combine into a single loan once construction is complete.

Consider a buyer purchasing a block in one of the newer subdivisions near Cheong Park. They settle on the land with a $100,000 deposit and begin paying interest on the land loan of $250,000. Six months later, their fixed price building contract for $450,000 is ready to start, and the construction drawdowns begin progressively over the following ten months. Once the home reaches practical completion, the total facility of $700,000 converts to a standard loan with principal and interest repayments.

Cost Plus Contracts and Builder Flexibility

While most project home loan structures use a fixed price building contract with a set progress payment schedule, some buyers working with custom builders may encounter a cost plus contract where the builder charges for actual costs incurred plus a margin. These contracts can be harder to finance because the final loan amount isn't fixed upfront, and lenders need to assess whether your borrowing capacity covers potential cost variations.

If you're considering a cost plus arrangement for a custom design in Croydon North, expect lenders to apply stricter conditions, require larger buffers in your approved loan amount, and potentially limit which construction loan options are available. Most mainstream lenders prefer fixed price contracts with registered builders because the risk of cost blowouts is contained.

Owner Builder Finance and Additional Requirements

Owner builder finance is available if you're managing the construction yourself, but lenders apply stricter criteria because you're taking on the project management risk that a registered builder would normally carry. You'll typically need a larger deposit, often 20% to 30%, and the lender will want evidence that you have relevant building experience, hold the required owner builder insurance, and have council approval in place before the loan is approved.

Progress payments under owner builder finance follow a similar staged structure, but instead of releasing funds to a builder, the lender releases them to you to pay sub-contractors like plumbers, electricians, and framers. You'll need to provide invoices and proof of payment at each stage before the next drawdown is released.

Renovation Finance and How It Differs

Renovation finance for an existing home in Croydon North follows a similar progressive structure to new construction, but the initial loan settles on the property purchase and any immediate costs, with additional funds held back for the renovation works. If you're looking at a house renovation loan for a property near Hawthorne Reserve that needs significant structural work, the lender will require detailed quotes, council plans if applicable, and sometimes a quantity surveyor's report to confirm the scope and cost.

The drawdown schedule for renovations is often more flexible than new builds because the milestones depend on the specific works being done. A knock-down rebuild is usually treated as construction finance rather than renovation finance because the original dwelling is demolished and the project is essentially a new build on existing land.

Interest Rate Options During Construction

Most lenders offer variable rates during the construction phase, with interest charged only on the amount drawn down at each stage. Some lenders also offer fixed rate options during construction, though these are less common and may come with higher rates or additional conditions. Once your build is complete and the loan converts to the permanent phase, you can choose between variable, fixed, or split rate structures depending on your preferences and what your lender offers.

Interest-only repayment options during construction help keep your costs lower while you're potentially managing rent or another mortgage, but you'll need to budget for the increase in repayments once the loan converts and principal repayments begin.

If your build in Croydon North is delayed due to weather, supply issues, or other factors outside your control, your interest costs will continue to accrue on the drawn portion for as long as construction takes. Most lenders allow construction periods of twelve months, with extensions available if needed, though prolonged delays can sometimes trigger a review of your loan terms.

Preparing Your Construction Loan Application

Your construction loan application will need a signed fixed price building contract with a registered builder, council approval or confirmation that a development application isn't required, detailed building plans and specifications, and evidence of your deposit and savings to cover the land and construction costs. Lenders also assess your income and existing commitments to ensure you can service the full loan amount once construction is complete and repayments increase.

If you're building in an established pocket of Croydon North close to Croydon North Primary School, the land component may be higher relative to the build cost compared to newer subdivisions further out, which can affect your loan to value ratio and whether lenders mortgage insurance applies.
