Getting approval for construction finance involves meeting requirements that differ substantially from a standard home loan. Lenders assess not just your borrowing capacity but also the viability of your building project, the builder's credentials, and how funds will be released throughout the construction phase.
Understanding what documentation and criteria lenders prioritise before you apply makes the difference between a smooth approval and months of back-and-forth requests for additional information. In Parramatta, where building activity spans everything from knockdown-rebuilds in older pockets near the CBD to new home construction in growth corridors like North Parramatta, knowing how to present your project properly matters.
Fixed Price Building Contracts and Why Lenders Require Them
Most lenders will only approve construction finance when you have a fixed price building contract with a registered builder. This contract locks in the total cost, provides a detailed scope of works, and establishes a progress payment schedule that protects both you and the lender throughout the build.
A cost plus contract, where the builder charges for materials and labour as the project progresses, creates uncertainty around the final loan amount. Lenders avoid this structure because there's no cap on what you might need to borrow. In contrast, a fixed price contract lets the lender assess the total project cost upfront and determine whether your deposit and borrowing capacity align with the build.
Consider a buyer planning a knockdown-rebuild in Parramatta's Oatlands precinct. They secured a fixed price contract for $650,000 with a local registered builder, provided council plans showing full development application approval, and demonstrated a 20% deposit that covered both the land value and construction cost. The lender approved the construction loan within two weeks because every requirement was addressed in the initial application. The builder's licence, insurance, and progress payment schedule were all verified upfront, leaving no gaps for the lender to question.
The Progressive Drawing Fee and How Interest Accrues
Construction loans only charge interest on the amount drawn down at each stage of the build, not the full loan amount. If your total loan is $650,000 but only $100,000 has been released for the slab, you're paying interest on $100,000 until the next progress payment is made.
Lenders charge a Progressive Drawing Fee to cover the cost of inspections and fund releases throughout the build. This fee typically ranges from $800 to $1,500 depending on the lender and the number of drawdowns. Some lenders cap it at five or six progress payments, while others allow more flexibility for custom builds with additional stages.
During construction, most borrowers make interest-only repayment options on the drawn amount. Once the build is complete and you move in, the loan converts to a standard principal and interest home loan. This structure keeps repayments manageable while the property isn't generating income or being lived in, but you need to factor in that your repayments will increase once construction finishes.

What Council Approval and Development Application Documents You'll Need
Lenders require evidence that your project has full council approval before they'll release any funds. A development application that's still pending or conditionally approved won't satisfy this requirement. You need stamped, approved plans that show the build complies with local zoning, setback, and height restrictions.
In Parramatta, council approval timelines vary depending on the complexity of the project and the specific precinct. A straightforward single dwelling in an established residential zone typically processes faster than a dual occupancy or a build in a heritage conservation area. Lenders won't wait indefinitely, so having your council plans finalised before you lodge the construction loan application keeps the process moving.
You'll also need to provide a copy of the building contract, a breakdown of the progress payment schedule, proof of the builder's insurance and licence, and evidence of your deposit. If you're using equity from an existing property, the lender will require a valuation of that property as well. Missing any of these documents at application stage delays approval and can result in rate lock periods expiring if the process drags out.
How the Progressive Payment Schedule Aligns with Build Stages
The progress payment schedule in your building contract determines when funds are released by the lender. Typical stages include deposit, base or slab, frame, lockup, fixing, and completion. Each stage must be inspected and signed off before the lender releases the next payment.
Lenders use independent inspectors or their own valuation teams to verify that the work has been completed to the standard outlined in the contract. If the inspector identifies defects or incomplete work, the payment is held until the builder rectifies the issues. This protects you from paying for work that hasn't been done, but it also means you need a builder who consistently meets quality standards and keeps the project on schedule.
Consider a scenario where a buyer in North Parramatta is building a custom design home on suitable land they already own. The builder provided a progress payment schedule with seven stages rather than the standard five. The lender agreed to the additional drawdowns but charged a slightly higher Progressive Drawing Fee to cover the extra inspections. Because the builder had a strong track record and the contract clearly detailed what work would be completed at each stage, the lender approved the structure without requiring the buyer to consolidate the stages.
Land and Construction Package Versus Building on Land You Already Own
If you're purchasing land and building in a single transaction, lenders treat it as a land and construction package. This structure typically requires a 10% to 20% deposit of the combined land and build cost. The land component settles first, and construction funds are released progressively as the build advances.
If you already own the land outright or have equity in it, lenders assess your borrowing capacity based on the land's current value plus the construction cost. This can increase how much you're able to borrow because the land acts as additional security. However, the lender will still require a valuation of the land and will factor in the combined loan-to-value ratio when determining approval.
In areas like Parramatta's Harris Park or Westmead, where land is more expensive relative to construction costs, buyers who already own the land often have an advantage. The equity they hold reduces the amount they need to borrow for the build, which improves serviceability and can open up access to more competitive construction loan interest rates.
Owner Builder Finance and Why It's Harder to Secure
If you're planning to manage the construction yourself as an owner builder, securing finance becomes significantly more difficult. Most mainstream lenders either decline owner builder applications outright or require a substantially larger deposit, often 30% or more.
Lenders view owner builder projects as higher risk because there's no licensed builder responsible for completing the work to Australian Standards. If the project stalls or the quality falls short, the lender has limited recourse. You'll also need to demonstrate experience in construction management, provide detailed costings for materials and subcontractors, and show that you have the financial capacity to cover cost overruns.
Some specialist lenders do offer owner builder finance, but the interest rates are typically higher and the approval criteria more stringent. If you're in Parramatta and considering this route, it's worth having a thorough conversation with a broker who can access lenders that specifically handle these projects rather than applying directly to a bank that doesn't offer the product.
Timing Requirements and When You Must Commence Building
Most construction loan approvals include a condition that you must commence building within a set period from the Disclosure Date, typically 12 months. If you don't start within that window, the approval lapses and you'll need to reapply. This protects the lender from approving a loan based on outdated property valuations or changed financial circumstances.
Delays in obtaining council approval, builder availability, or finalising the contract can all push you beyond this timeframe. If you're close to the deadline and the build hasn't started, contact your lender immediately. Some will extend the approval period if you can demonstrate that the delay is beyond your control and that your financial position hasn't changed.
In Parramatta, where demand for quality construction services is high, builder availability can stretch out several months. Securing your builder early and locking in start dates before you apply for finance reduces the risk of running into timing issues that jeopardise your approval.

Frequently Asked Questions
What type of building contract do lenders require for construction finance?
Lenders require a fixed price building contract with a registered builder that locks in the total cost and includes a detailed progress payment schedule. Cost plus contracts are generally not accepted because they create uncertainty around the final loan amount.
How does interest work during the construction phase?
You only pay interest on the amount drawn down at each stage of the build, not the full loan amount. Most borrowers make interest-only repayments during construction, then convert to principal and interest repayments once the build is complete.
Do I need council approval before applying for a construction loan?
Lenders require full council approval with stamped, approved plans before they'll release any funds. A development application that's still pending or conditionally approved won't satisfy lender requirements.
Is it harder to get finance as an owner builder?
Most mainstream lenders either decline owner builder applications or require a much larger deposit, often 30% or more. Specialist lenders do offer owner builder finance, but with higher rates and stricter approval criteria.
How long do I have to start building after loan approval?
Most construction loan approvals require you to commence building within 12 months from the Disclosure Date. If you don't start within that window, the approval lapses and you'll need to reapply.
