Construction Loans Melbourne: What to Expect at Every Stage in 2026

Building your own home — or an investment property — is one of the most rewarding things you can do as a property owner. It's also one of the most financially complex. A construction loan works very differently to a standard home loan, and understanding how it works before you sign a building contract could save you a lot of stress and money.

This guide walks you through exactly how construction loans work in Melbourne in 2026, what you need to prepare, and what pitfalls to watch for along the way.

What Makes a Construction Loan Different?

With a standard home loan, the lender gives you all the money on settlement day and you begin repayments immediately on the full amount. A construction loan works differently — and for good reason.

When you're building, the builder doesn't receive the full contract price on day one. They're paid in stages, as each part of the build is completed. Your construction loan works the same way. The lender holds the full approved amount and releases it progressively — only when the builder has completed a stage and an independent inspection confirms the work is done.

During construction, you only pay interest on what's been drawn down — not the full loan limit. This means your repayments start small and increase as more of the loan is used.

The Five Progress Payment Stages

Most building contracts in Victoria are structured around five standard progress payment stages. Your lender will release funds at each stage after an independent inspection confirms the work is complete.

Stage	What's Completed	Typical % of Contract Price
1. Slab / Base	Site preparation, footings, and concrete slab poured	~10–15%
2. Frame	Wall frames and roof trusses erected	~20–25%
3. Lock-Up	External walls, windows, roof covering, and doors fitted — the home is now lockable	~20–25%
4. Fixing / Fit-Out	Internal fit-out: plaster, cabinetry, internal doors, tiles, plumbing and electrical rough-in	~20–25%
5. Practical Completion	Final inspections, certificate of occupancy issued, keys handed over	~10–15%

The percentages above are approximate — your building contract will specify the exact amounts for each stage. The first progress payment (deposit) is typically required before construction begins, and your lender will usually fund this from day one.

What You Need Before Applying

A construction loan requires more documentation than a standard home loan. Preparing these in advance will speed up your approval considerably:

• A signed, fixed-price building contract — lenders will not approve a construction loan without this
• Council-approved building plans and specifications
• Builder's HIA or MBA membership and evidence that the builder is registered with the Victorian Building Authority (VBA)
• Builder's public liability and domestic building insurance (required by lenders)
• Signed contract of sale if you're purchasing the land as part of the same transaction
• Standard income documents (payslips, tax returns, employment letter)
• Evidence of deposit / genuine savings

Fixed-Price vs Cost-Plus Building Contracts

The type of building contract you sign has significant implications for your budget risk — and your lender's appetite.

Fixed-price contracts mean the builder commits to completing the build for a set price. If costs increase (apart from agreed variations), the risk sits with the builder, not you. Most major residential builders in Melbourne use this contract type, and it's strongly preferred by lenders.

Cost-plus contracts mean you pay the builder's actual costs plus an agreed margin. This can work well for custom or complex builds where a fixed price is difficult to determine upfront, but it gives you less budget certainty. Some lenders are cautious about cost-plus contracts and will want a more detailed assessment of the estimated costs.

Whatever contract you sign, always read the variations clause carefully — this is where costs can blow out even on a "fixed" contract.

How the Drawdown Process Works

When your builder completes a stage and sends you a progress claim, here's the process:

1. Your builder issues a progress claim invoice for the completed stage
2. You review and approve the claim
3. You submit the claim to your lender with a drawdown request
4. The lender organises an independent progress inspection (at their cost)
5. Once the inspector confirms the work is complete, the lender releases the funds directly to the builder
6. You never actually touch the money — it goes straight from lender to builder

Processing a drawdown typically takes 3–7 business days once the inspection is complete. Build this timeline into your expectations when planning with your builder — they may need payment within a certain number of days of issuing their progress claim.

Common Mistakes to Avoid

After working with many Melbourne clients through construction finance, these are the errors we see most often:

• Signing the building contract before getting finance approved — if finance falls through, you may be locked into a contract you can't fund
• Underestimating the total cost — landscaping, fences, driveways, window coverings, and appliances are often not in the building contract and can add tens of thousands to your costs
• Not understanding what the builder's insurance covers — domestic building insurance protects you if the builder becomes insolvent; it does not cover all disputes
• Ignoring the interest during construction — even though you're only paying interest on drawn amounts, these payments still need to be funded alongside any existing rent or mortgage during the build period
• Choosing the cheapest builder over the most suitable one — a failed builder mid-construction is far more costly than any savings at the start

Frequently Asked Questions

Can I use a construction loan if I already own the land?

Yes. If you already own land outright or have an existing home loan on it, a construction loan can be structured to cover just the build costs. Your broker will work with the lender to use the land equity as part of your deposit or security.

What happens if the build goes over budget?

This is a critical question to ask your builder before signing anything. With a fixed-price contract, any budget overrun (outside of agreed variations) is the builder's responsibility. Cost-plus contracts pass variations to you. If costs genuinely exceed your loan limit, you'll need to either renegotiate the loan, use your own funds, or work through a solution with your broker and lender.

Do I pay interest during construction?

Yes — but only on the amount drawn down, not the full loan limit. During construction, most lenders put you on interest-only repayments on the drawn portion. Once the certificate of occupancy is issued and the final drawdown is made, repayments typically switch to principal and interest unless you've arranged otherwise.

What is a progress inspection and who organises it?

A progress inspection (or drawdown inspection) is an independent check that the work claimed in a progress claim has actually been completed to the required standard. The lender organises and pays for these. They protect both you and the lender by ensuring funds are only released for work that is genuinely complete.

Can I build an investment property using a construction loan?

Yes. Construction loans are available for both owner-occupied builds and investment properties. Lenders may apply slightly different criteria and LVR limits depending on the intended use, and some lenders are more active in this space than others — your broker will point you to the right options.
