Beginner's Guide to Construction Loan Documentation

A construction loan application requires more documentation than a standard home loan because the lender is funding a project that doesn't exist yet.

You're essentially asking a bank to release funds in stages as your home gets built, which means they need proof that the build is properly planned, properly priced, and properly managed. The documentation you provide gives them confidence that the project will be completed on time, on budget, and to a standard they can lend against. Most of the paperwork falls into three categories: personal financials, property information, and building contracts.

What Lenders Ask for Before Pre-Approval

Lenders assess your income, expenses, and deposit the same way they would for any home loan. You'll need payslips, tax returns if you're self-employed, bank statements showing your savings history, and a clear picture of your existing debts. The difference with construction finance is that lenders also want to see the land contract if you've already purchased, or the house and land package agreement if you're buying both together. If the land isn't settled yet, they'll assess based on the contract price and any deposit already paid.

Your deposit needs to cover the land and construction costs combined. For a land and construction package, a 10% deposit of the total contract value is typically the minimum, though some lenders will go lower with lender's mortgage insurance. If you already own the land outright, that equity can often be used in place of cash, which opens up options for owner occupiers looking to build in Ocean Reef without needing to sell first.

The Building Contract and Why It Matters

The building contract is the most important document in your application. Lenders will only approve construction funding if the contract is with a registered builder and includes a fixed price. They need to see the total contract price broken down by stage, along with a start date and estimated completion timeline. The contract also needs to specify whether it's a turnkey build or if there are owner-supplied items, as this affects how the lender structures the drawdown schedule.

Consider a buyer who's signed a fixed price building contract for a new home in Ocean Reef with a local registered builder. The contract sets out five progress payments: base stage, frame stage, lockup stage, fixing stage, and practical completion. The lender reviews the contract and confirms that the builder holds the required insurance and that the payment schedule aligns with industry norms. Because the contract price is fixed and the builder is licensed, the lender is comfortable approving the loan and setting up a progressive drawdown that matches those five stages.

Plans, Permits, and Council Approval

You'll need to provide a full set of building plans with your application, along with proof that a development application has been lodged or approved by the local council. Most lenders won't settle the land component until council approval is confirmed, as they won't fund a project that can't legally proceed. The plans also help the lender's valuer assess whether the completed home will be worth what you're borrowing.

In Ocean Reef, council approval timelines can vary depending on whether the design is straightforward or requires variations to local planning schemes. If you're building close to the coast or on a sloping block, the approval process may take longer due to additional environmental or engineering assessments. It's worth starting the development application early so the approval is in place by the time your loan is ready to settle.

The Valuation Report and Why Lenders Order Two

Lenders typically order two valuations during a construction loan: one at the start and one at completion. The initial valuation assesses the land as-is and provides an estimate of what the completed home will be worth once the build is finished. This "as if complete" valuation determines how much the lender is willing to lend. If the valuer estimates the finished home will be worth less than the combined land and construction costs, the lender may reduce the approved loan amount or ask you to contribute more equity upfront.

The second valuation happens after practical completion, when the home is finished and the builder has been paid in full. This confirms that the property is worth what the lender expected and that the loan can now convert from construction funding to a standard home loan with principal and interest repayments.

How the Progressive Drawdown Works

Once the loan is approved and the land has settled, the lender holds the construction funds in a separate account. These funds are released to the builder in stages, based on the progress payment schedule in your building contract. Before each drawdown, the lender arranges a progress inspection to confirm the work has been completed to the standard claimed by the builder. If the inspector is satisfied, the lender releases the funds directly to the builder within a few days.

You only pay interest on the amount that's been drawn down so far, not the full loan amount. During construction, most borrowers are on interest-only repayments, which keeps costs lower while the build is underway. Some lenders also charge a progressive drawing fee each time funds are released, typically between $150 and $400 per drawdown.

What Owner Builders Need to Know

If you're planning to act as an owner builder, the documentation requirements are significantly higher. Lenders want to see detailed quotes from each subcontractor, proof that you hold an owner builder permit, and evidence that you have the skills or experience to manage the build. Some lenders won't offer owner builder finance at all, while others will lend but at a lower loan-to-value ratio, often capping it at 60% to 70% of the total project cost.

You'll also need to provide a cost-plus contract breakdown showing how much each stage will cost, along with statutory declarations confirming that subcontractors have been paid before each drawdown is released. The process is more hands-on and requires you to coordinate inspections, lodge claims, and manage the cashflow between each stage.

Getting Your Documents in Order

Before you apply, gather your building contract, council-approved plans, land contract or title, proof of deposit, and all the usual income and asset documents your broker will request. If you're working with a project builder on a house and land package, they'll often provide a full document pack that includes the contracts, plans, and specifications in a format lenders recognise. If you're doing a custom build, make sure your builder can provide a detailed tender or fixed price contract that breaks down the scope of work and payment stages.

Most of the delays in construction loan applications happen because a document is missing or doesn't meet the lender's format. Having everything ready upfront means your broker can submit a complete application and get you to approval faster.
