A construction loan doesn't hand over the money. It releases it, as your home rises.
Building is different to buying, and so is the loan. Instead of one lump sum, funds are released in stages as each milestone is finished — and you pay interest only on what's been drawn, not the whole loan. It's a structure designed to protect you: the lender pays for work once it's actually done. Here's exactly how the money flows, stage by stage, plus the Gold Coast builder landscape, approval rules, and what to have ready before the call.

Six stages, released as the build hits each milestone.
Your builder invoices at each completed stage; the lender inspects, then releases that slice of the loan. The bar shows how much of your loan is drawn as the build progresses — you're only ever charged interest on what's actually been paid out.
Stage percentages are typical only and illustrative — the actual split is set by your builder's fixed-price contract and varies by lender and state. Before the final payment, the lender orders an "as if complete" valuation to confirm the build matches the approved plans. Not an offer of credit.
Three features you won't find on a normal home loan.
Interest-only while you build
During construction you pay interest only, and only on the funds drawn so far — so early on, when little is drawn, repayments are low. At completion it converts to standard principal & interest.
Fixed-price building contract
Lenders require a signed fixed-price contract from a licensed builder. It caps the cost, defines each stage, and protects you and the lender from blowouts before a dollar is released.
Valued "as if complete"
The lender values the property on what it'll be worth once built, per your plans and contract — so your borrowing is assessed against the finished home, not the empty block.
Construction finance suits three kinds of borrower.
Land & build
Block purchased or under contract, builder's quote locked in. We roll both into one facility — land settles, build draws down in stages.
Knock-down rebuild
You own the land. We finance demolition as stage one, then new construction, using your land equity.
Trade-up builders
Selling your existing home and building new. We can bridge timing so you don't hold two properties.
Owner-builders
Possible but tougher — only a few lenders, lower LVR (often ~50–60%), no builder's licence or warranty.
Gold Coast building is strong, costs are moderating, but insolvencies remain a risk.
The Gold Coast is one of Australia's hottest construction markets. That means choice of builders, competitive pricing, and growing lender appetite — but also tight budgets at builder level and the need to protect yourself with a rock-solid contract.
Sources: CoreLogic median house prices (2026); RLB construction cost forecasts (2026 outlook); builder industry cost guides. Gold Coast has absorbed 80,000+ relocations in the past 12 months, with vacancy rates at 1.8%, pushing demand for new stock.
Five things that swing approval on construction loans.
Fixed-price contract, QBCC builder
Non-negotiable. Lenders require a signed fixed-price contract from a QBCC-licensed builder matching your plans. This protects both of you from cost blowouts.
Valuation "as if complete"
Before drawdown, the lender values the finished home against your plans and contract. This sets the borrowing ceiling and confirms the property holds value.
Deposit & LVR
Most lenders want 20% deposit (some allow 5–10% with mortgage insurance), assessed on the finished value. Higher-value rebuilds can borrow more on the same deposit percentage.
Home warranty insurance
QBCC Home Warranty scheme required — covers cost overruns, defects, incomplete work. Your safety net if the builder fails mid-build.
Full-loan serviceability
IO repayments during build are low, but at completion you must service the full P&I amount at the bank's test rate. This is where most applications fail.
Staged payments aren't red tape. They're your safeguard.
Construction is the hardest sector in the economy right now — it accounted for around 27% of all company insolvencies in Australia (about 2,975 businesses) in a single recent year. A second wave of insolvencies is forming in 2026, with builders signing fixed-price contracts based on estimates that no longer match real costs. The way a construction loan is built is your defence against it.
Because funds are released only after each stage is finished and inspected, you never pay ahead for work that hasn't happened. A fixed-price contract with a licensed builder and QBCC insurance caps your exposure. On the Gold Coast, where builder competition is fierce and budgets tight, this protection is more important than ever.

Illustrative example, not a real client.
A couple buys a $600,000 block on the Gold Coast and contracts a licensed builder at a fixed price of $400,000. Here's how the loan works out:
Land & construction: $600k block, $400k build
Total: $1,000,000 | Deposit (20%): $200,000 | Loan: $800,000
Drawdown: 5% at contract signing, 15% slab, 20% frame, 25% lock-up, 20% fit-out, 15% completion.
Interest during build: 8 months typical. At slab (20% drawn), interest is ~$2,667/month. Increases as more draws. At completion, full $800,000 is charged.
At completion: Valuation confirms $1,000,000 finished value. Loan converts IO to P&I at 7% over 30 years = ~$5,330/month.
Round numbers, simplified. Your actual drawdown, rates and repayment depend on lender, contract, location and serviceability. Not an offer of credit.
Queensland offers $30,000 for eligible new builds.
If you're building new (not knock-down rebuild), you may qualify for the Queensland First Home Owner Grant, which continues through 2030.
Who qualifies
First home buyer, at least 18, Australian citizen or PR, land-plus-home under $750,000, home never occupied as residence.
The grant
$30,000 at settlement on eligible contracts from 1 July 2026. Must move in within 12 months, live there 6+ months.
How it helps
Reduces deposit needed — $30,000 off a $500,000 build means less cash or more borrowing power. We confirm eligibility at the start.
Knock-down rebuilds
Ineligible for the $30,000 FHOG (it's for new builds only), but other concessions may apply if you own the land — we'll advise.

Lenders want these documents before they can move forward.
Essential documents
Builder's contract, land title, council plans, QBCC insurance quote, deposit proof, last 2 years tax (or recent payslips), ID and proof of address. We'll tell you exactly what's needed — mostly copies, nothing complex. If you're self-employed, we'll want your accountant's letter of income verification too.
Construction loans, answered straight.
How do progress payments actually work?
Builder invoices at each stage (slab, frame, lock-up, fixing, completion). Invoice and photos go to the lender, who inspects the work, confirms it matches the contract and plans, then releases the stage payment. You pay the builder from that. The lender never pays for work not done — that's your protection.
What's an "as if complete" valuation?
Before your first drawdown, the lender orders a valuation of the finished home — assessed on the plans you'll build to and the contract price. This sets the ceiling on what you can borrow. It's crucial: if the valuation comes in below the land + build cost, you'll need a bigger deposit or smaller scope. On the Gold Coast, values are rising, so this rarely kills a deal — but always do it early.
Do I have to pay interest during construction?
Yes, but only on what's been drawn. Early stages are tiny — maybe $50,000 drawn means $3,500/year interest at 7%. At practical completion, you'll be paying on the full loan. Many borrowers budget for this with offset accounts or redraw.
What happens if the builder goes insolvent mid-build?
The QBCC Home Warranty Insurance scheme covers cost overruns, defects, and incomplete work — up to the contract price. If the builder walks away, the insurer either hires a new builder to finish or pays out the difference. You don't lose money. This is why QBCC insurance is mandatory for lenders.
Can I build on a block I already own?
Yes. We can structure a construction loan on land you own outright, or we can do a "top-up" loan if your existing home loan has equity we can use. This is common for people building a knock-down rebuild or a granny flat.
What if my builder is overseas or interstate?
They still need to be licensed in Queensland (QBCC) to build here and access lender funding. If you've chosen a builder from another state, confirm they're registered to work in Queensland — if not, they'll need to be.
How long does it take to get approved?
Once you've got the contract, plans and insurance quote, most lenders take 5–10 business days for the valuation, then another 5–7 days for formal approval. Total: 2–3 weeks if everything's in order. We'll manage the timeline so you don't hold up your builder.
Is interest-only forever?
No. At practical completion (when the build is finished and certified), the loan automatically converts to principal & interest repayments. You don't need to refinance — it just happens. Your repayment then matches a standard 30-year home loan.
The Gold Coast landscape: why it's a good time to build, and what to watch.
Why build on the Gold Coast now?
The market is hot: 80,000+ people have moved here in the past year, vacancy is 1.8%, and median prices are up 8% annually. Plenty of builders are active, competition is fierce, and lenders love construction loans here. But tight labour and 5.5% cost escalation mean builder margins are under pressure — some sign fixed-price contracts at estimates that don't hold up mid-build. This is why staged payments and QBCC insurance are critical. Choose a builder with a Coast track record, verify their QBCC history, and lock in a fixed-price contract that reflects current labour and material costs. We'll vet the numbers before you commit.
