Building Finance Requirements and What Lenders Actually Ask

Construction loans work differently to standard home loans because lenders release funds in stages as your build progresses.

You'll need to meet specific criteria before approval, provide detailed documentation about your build, and understand how progressive drawdowns work. For Brisbane clients, council approval timeframes and builder availability also affect when you can commence building within a set period from the Disclosure Date, which shapes how lenders structure your facility.

Fixed Price Building Contracts Make Approval Straightforward

Lenders prefer fixed price building contracts because they know exactly what the project will cost. A fixed price contract with a registered builder gives the lender certainty that your loan amount covers the full build, which reduces their risk and makes your application more likely to succeed.

In our experience, applications with fixed price contracts settle faster than cost plus arrangements. Consider a buyer planning a custom design in Carindale with a $680,000 contract. Their lender requested the signed building contract, council approved plans, and an engineer's certificate for soil conditions. With those three documents in place, approval came through within ten days. The same buyer initially approached us with preliminary plans and a builder's estimate, which wouldn't have met lender requirements for formal approval.

Cost plus contracts require additional scrutiny because the final cost isn't locked in. Lenders typically add a buffer to the loan amount or require you to hold contingency funds separately, which affects how much you can borrow against the land value and your deposit.

How Progressive Drawdowns Actually Work

Lenders only charge interest on the amount drawn down at each stage, not the full approved loan amount. Your builder submits invoices at set stages, the lender arranges a progress inspection, and then releases funds directly to the builder once the work is verified.

A standard progress payment schedule divides the build into five or six stages: base stage after the slab is poured, frame stage when the roof is on, lockup once external walls and windows are complete, fixing stage when internal linings are finished, practical completion, and final completion after defects are rectified. Each stage typically represents 15-20% of the total contract value.

Most lenders charge a Progressive Drawing Fee of around $150-300 each time funds are released. This covers the cost of sending an assessor to verify the work is complete. Some lenders cap this fee at five inspections, while others charge for every drawdown including variations.

During construction, you'll make interest-only repayment options on the amount drawn to date. Once the build completes, the loan converts to principal and interest repayments unless you've arranged a construction to permanent loan structure that locks in terms at approval.

Documentation Requirements Before You Apply

You'll need council approved plans before most lenders will assess your application. Preliminary or draft plans aren't sufficient because the lender needs to see that the development application has been approved and all conditions met.

For a land and construction package, lenders require a contract of sale for the land, evidence you've paid the deposit, and confirmation of settlement date. If you already own the land, they'll need a current valuation showing the land is suitable for the proposed dwelling. Brisbane properties in flood-prone areas like parts of Rocklea or low-lying sections of Hamilton require additional engineering reports, which can add three to four weeks to your preparation timeline.

Your builder needs to hold appropriate licences and insurance. Lenders verify the builder's registration with the Queensland Building and Construction Commission and check their insurance covers contract works and public liability. Owner builder finance is available but requires you to demonstrate building experience and hold an owner builder permit, which most lenders assess more conservatively than projects with a registered builder.

If your build includes unusual features or materials not covered by standard construction insurance, you'll need to arrange additional cover before drawdown. We regularly see this with architecturally designed homes in suburbs like Paddington or Bardon where heritage overlays or character home requirements affect materials and methods.

Interest Rates During Construction

Construction loan interest rates sit slightly higher than standard variable rates because of the additional administration and risk involved in staged funding. The difference is typically 0.10% to 0.30% depending on the lender and your deposit size.

Some lenders offer the option to fix your construction loan interest rate during the build period, then convert to a variable or fixed rate once construction completes. This protects you from rate rises during the 6-12 month construction period, though the fixed rate during construction usually sits higher than the variable equivalent.

Your repayments during construction depend entirely on how much has been drawn down. In the first few months after the base stage, you might only be paying interest on 20% of your total loan. By lockup stage, you're typically paying interest on 60-70% of the approved amount.

Getting Your Application Right

Start your construction loan application at least eight weeks before you need funds. Brisbane council approval processes vary by suburb, and lenders won't formally approve your application until plans are stamped. If you're building in growth areas like Coorparoo or Tingalpa where council processing times are longer, factor that into your timeline.

Provide your broker with the building contract, council plans, soil test results if available, and proof of any additional funds you're contributing beyond the loan. Lenders assess your borrowing capacity based on the completed property value, not just the construction cost, so if you own land valued at $400,000 and you're building a $500,000 home, they're lending against a projected $900,000 asset.

Any variations to the building contract during construction need lender approval before the builder proceeds. If your variation increases the contract price, you'll either need to fund the difference from your own resources or apply to increase your loan, which requires a fresh assessment of your borrowing capacity.

If you're ready to discuss your build plans and what documentation you'll need, call one of our team or book an appointment at a time that works for you. We'll review your contract, identify which lenders suit your build type, and walk you through exactly what's required before you submit your application.
