Smart ways to approach construction loan structures

Building a home on the Gold Coast means thinking through how the money flows, not just what the house will look like.

Construction finance works differently to a standard home loan because the bank releases funds progressively as your build reaches milestones, rather than handing over the full amount upfront. You pay interest only on what's been drawn down, which means your repayments start small and increase as the project progresses. The way your loan is structured affects how much you pay during the build, when your builder gets paid, and how you transition into your finished home once the keys are handed over.

How progressive drawdown works in practice

The lender releases funds in stages tied to specific construction milestones. Typically, this includes a base stage payment once the slab is poured, a frame stage payment when the roof goes on, a lock-up stage payment when the home is secure, a fixing stage payment when the internal fit-out is complete, and a final payment at practical completion. Your builder submits a claim after reaching each stage, the lender arranges an inspection to confirm the work matches the claim, and then releases the funds directly to the builder. You only pay interest on the amount drawn down so far, not the full loan amount.

Consider someone building a custom home in Elanora with a total build cost of $650,000. After the slab is poured, the lender releases $130,000. Interest for the first few weeks is charged only on that $130,000, not the full loan. Once the frame and roof are complete, another $195,000 is released, and interest is then charged on the combined $325,000. This continues through each stage until the home is finished. The progressive structure means you're not paying interest on money that hasn't left the bank yet, which keeps costs lower during the build phase.

Construction to permanent loan or separate loans

Some lenders offer a single loan that converts from construction to a standard home loan once the build is complete. Others require you to take out a construction-specific facility and then refinance into a permanent loan after settlement. The single-loan structure is more common and usually more straightforward. You apply once, the loan is approved based on the completed property value, and once the build finishes, your loan automatically switches from interest-only on progressive drawdowns to principal and interest repayments on the full amount.

A two-loan structure might suit someone who wants to secure a particularly low rate on their permanent loan or who is building with a lender that doesn't offer a combined product. The downside is that you go through two application processes, pay two sets of fees, and need to requalify for the permanent loan at the end. For most Gold Coast builds, particularly house and land packages in suburbs like Ormeau or Helensvale, the construction to permanent loan is the more practical choice.

Fixed price building contracts and payment schedules

Most construction loans require a fixed price building contract with a registered builder. This contract sets out the total build cost, the payment schedule tied to each stage, and the timeframe for completion. Lenders prefer fixed price contracts because they limit cost variation and provide certainty around the final loan amount. The payment schedule needs to align with the lender's drawdown stages, which is why most volume builders structure their contracts to match standard lender milestones.

If you're working with a custom builder, the contract might include variations or a cost-plus arrangement for certain elements. Some lenders will accept this, but they'll want a detailed breakdown of estimated costs and may hold back a contingency amount until final costs are confirmed. For someone building a custom design in Currumbin Waters or Palm Beach, it's worth confirming with your mortgage broker which lenders are comfortable with your specific contract structure before lodging an application.

Interest-only repayments during construction

During the build phase, most borrowers make interest-only repayments on the amount drawn down. This keeps repayments manageable while you might still be paying rent or covering another mortgage. Once the build is finished and the loan converts to a standard home loan, you switch to principal and interest repayments based on the full loan amount.

In a scenario where someone is building in North Lakes with a $500,000 construction loan, they might pay around $1,000 per month in interest after the first drawdown, rising to $2,500 per month by the time the build is complete. Once the loan converts, their principal and interest repayment might be $3,200 per month. Planning for that jump in repayments is important, particularly if you're holding onto an existing property during the build or managing other commitments. Lenders assess your ability to service the full loan amount at completion, not just the interest during construction, so your borrowing capacity is based on the final repayment, not the interim one.

Land and construction packages vs buying land separately

Some buyers purchase a land and construction package from a developer, where the land and build are contracted together. Others buy land first and then arrange a building contract separately. Both approaches work with construction finance, but the structure differs slightly. With a package, the land is usually settled first, and the construction loan is drawn down progressively after that. If you buy land separately, you might take out a land loan first and then roll it into a construction loan once the building contract is signed.

Buying land separately gives you more flexibility in choosing your builder and design, but it also means you're carrying the land cost before construction starts. If you're looking at building in growth areas like Ormeau or Pimpama, a package deal often includes council approvals and developer contributions already factored in, which can speed up the process. Either way, the lender will want to see council approval, a fixed price building contract with a registered builder, and confirmation that you can commence building within a set period from the loan settlement.

Progressive drawing fees and other costs

Lenders charge a progressive drawing fee each time they release funds to the builder. This fee covers the cost of the inspection and administration, and typically ranges from $200 to $400 per drawdown. With five or six progress payments across a build, these fees add up to around $1,500 to $2,000 in total. Some lenders include this fee in the loan balance, while others require you to pay it directly. It's not a large cost relative to the overall build, but it's worth factoring into your budget alongside other settlement costs and builder deposit requirements.

You'll also need to account for any upfront deposit paid to the builder, which is usually 5% to 10% of the build cost and comes from your own savings rather than the loan. Council and developer charges, soil tests, and any site-specific preparation work also sit outside the construction loan in most cases. If you're building in an area like Hope Island or Sanctuary Cove where there are body corporate or estate levies, those ongoing costs start as soon as you settle on the land.

Owner builder finance and spec home structures

If you're acting as an owner builder, fewer lenders will support the project, and those that do typically require evidence of building experience, detailed costings, and a larger deposit. Owner builder finance involves more risk for the lender because there's no registered builder providing contract certainty or warranty insurance. Drawdowns are still progressive, but the approval criteria are stricter and the interest rate is often higher.

Spec home finance, where a builder constructs a home on spec to sell after completion, follows a similar progressive structure but is assessed as a commercial or investment lending proposition rather than owner-occupied. Most Gold Coast families building a home to live in will use a standard construction loan with a registered builder and fixed price contract, which gives access to the widest range of lenders and the most competitive pricing.

Building a home takes time, patience, and a finance structure that works with your builder's schedule and your cashflow.
