Construction Loans

Building a new home or investment property is one of the biggest projects most Australians ever take on, and the finance behind it works differently to a standard home loan. A construction loan is designed specifically to fund a build in stages, matching your loan drawdowns to the progress of the work rather than handing you the full amount on day one.

If you’re planning to build, knock down and rebuild, or complete a major renovation, we can help you understand your options, compare lenders, and structure a loan that suits your project and your budget.

What Is a Construction Loan?

A construction loan is a type of home loan that releases funds progressively as your build reaches agreed milestones, rather than in one lump sum at settlement. This protects both you and the lender, because you’re only borrowing (and paying interest on) the amount that has actually been spent at each stage of the build.

Most construction loans in Australia are structured around a fixed-price building contract with a licensed builder, and funds are released in line with a standard progress payment schedule. A typical schedule includes stages such as:

Slab or base stage

Site preparation and foundations

Frame stage

Wall and roof framing completed

Lock-up stage

External walls, windows, and doors installed

Fixing stage

Internal fittings such as cabinetry, doors, and skirting

Practical completion

The home is finished and ready to move into

Before each drawdown, most lenders arrange a progress inspection or valuation to confirm the work has been completed to the value being claimed. This helps prevent overpayment and keeps the build on track financially.

How Construction Loans Work

During the construction phase, most lenders only charge interest on the funds that have actually been drawn down, rather than the full approved loan amount. This is known as an interest-only construction period, and it can help keep your repayments lower while you’re building, particularly if you’re also covering rent or a mortgage on your current home.

Once construction is complete, the loan typically converts to a standard principal and interest home loan, and repayments are recalculated based on the full loan balance.

Because construction loans are assessed against a building contract rather than an existing property, lenders will generally want to see:

A fixed-price building contract with a licensed builder
Council-approved plans and permits
Specifications and a schedule of finishes
Builder’s insurance and relevant licensing details
A progress payment schedule

If you already own the land, this can typically be used as equity towards the build, which may reduce the amount you need to borrow.

Construction vs Standard Home Loans

The core difference comes down to how funds are released. A standard home loan pays out the full amount at settlement because you’re buying an established property. A construction loan releases funds in stages as the build progresses, which means less risk for the lender and a repayment structure that better matches your cash flow during the build.

Interest rates, fees, and lending criteria for construction loans can vary between lenders, and not every lender offers them on the same terms. This is one of the areas where getting advice early can make a real difference to how smoothly your build is financed.

Owner-Builder Construction Loans

If you’re planning to manage the build yourself rather than using a licensed builder, be aware that owner-builder loans are treated differently by most lenders. They’re generally considered higher risk, often come with stricter eligibility requirements, and are only offered by a smaller number of lenders. It’s worth discussing your specific plans with us early so we can point you toward lenders who are a realistic fit.

Why talk to a broker about your construction loan?

Construction loans involve more moving parts than a standard mortgage: progress payments, valuations at each stage, contract review, and coordination with your builder’s payment schedule.

A broker can help you compare lenders that offer construction finance, understand the documentation each one requires, and structure the loan around your build timeline and budget, so you can focus on the project rather than the paperwork.

Frequently Asked Questions about Construction Loans

What is the difference between a land loan and a construction loan?

A land loan finances the purchase of a vacant block, while a construction loan finances the build itself. Many people take out a land loan first and then move to a construction loan once they’re ready to build, or combine the two into a single facility, depending on the lender.

How are construction loan funds released?

Funds are typically released in stages that align with your building contract, such as slab, frame, lock-up, fixing, and completion. Most lenders require a valuation or inspection before each drawdown to confirm the work has been completed to that stage.

Do I pay principal and interest during construction?

Most construction loans are interest-only during the build, with interest charged only on the funds drawn down so far. Once the build is complete, the loan generally reverts to standard principal and interest repayments.

Can I use land I already own for a construction loan?

Yes, in most cases. If you own the land outright or have equity in it, this can generally be used towards the cost of the build, which may reduce how much you need to borrow.

What documents will I need to apply?

Typically a fixed-price building contract, council-approved plans, a schedule of finishes, builder’s insurance details, and evidence of the builder’s licensing, along with the usual documents required for any home loan application.

What happens if the build costs more than expected?

If costs increase beyond the original contract price, known as a cost overrun, you may need to fund the difference yourself or discuss additional borrowing with your lender. It’s worth building some contingency into your budget from the outset.

What if my builder becomes insolvent during construction?

This is a risk in any build, which is why lenders generally require a fixed-price contract with a licensed, insured builder. Speak with us and your legal adviser about the protections in place, including any builder’s warranty insurance relevant to your state or territory.

Do I need to fix my interest rate for a construction loan?

This depends on the lender and your circumstances. Some lenders offer fixed or variable options for the construction period, though rate locks and fixed rates can work differently while a loan is progressively drawn down. We can talk you through what’s available.

How long does a construction loan last?

Construction periods commonly run somewhere between six and twelve months, though this depends on the size and complexity of the build. Most lenders set a maximum construction period as a condition of approval.

Can I renovate using a construction loan?

Yes, substantial renovations are often financed in a similar way to a new build, with funds released in stages against a fixed-price contract. Smaller renovations may instead be suited to a standard home loan top-up or a line of credit, depending on the scope of work.
