A construction loan is designed for borrowers building a home, rather than buying an existing property and helps to keep costs down during the building process.
Unlike a regular home loan, a construction or building loan covers expenses incurred as the building process takes shape. They're typically drawn down in stages and incur interest only repayments. This helps keep repayments low while a home is being built.
At the end of a build process, construction loans generally transform into a normal mortgage product.
Construction loans operate through a process known as 'progressive drawdown.' The loan amount is progressively disbursed as different stages of the building works are completed.
As the process continues, you'll only pay interest on the funds used during the build and you won't need to repay the principal until the construction is complete.
So, if your total building cost are expected to be $400,000 but you've only needed to hand over $100,000 of borrowed funds so far, you'll only be charged interest on that $100,000 and not on the $400,000 total.
That helps to keep repayments low in the period you can't live in the property and will likely still have the outlay of rent.
Your lender will make payments to your builder at every stage of construction. As each phase is completed, your lender will require you to present an invoice from your builder to issue payment.
Your lender will likely be very involved in the process. Typically, they will send someone to inspect the progress of construction before releasing the next payment to your builder.
Comparing construction loans is simple. Browse some of the market's most competitive deals in the table above, and filter the options to find a mortgage that suits your situation. Here are some of the key aspects to look out for:
Interest rates are typically higher on construction loans than on traditional home loans. Interest also works slightly differently on construction loans, as lenders only charge interest on the funds paid to a builder at a given time (not the entire build cost) and borrowers generally only need to pay interest until the works are complete.
Like with any home loan product, borrowers should also pay attention to the comparison rate. This figure factors in interest costs, as well as additional fees and built-in rate changes. It's calculated considering a $150,000 home loan over 25-years.
Building contracts come in fixed cost or cost plus options. As the name suggests, a fixed cost contract sets a 'fixed' price for the works being done. Under a cost plus contract, costs can easily increase if the scope of work changes. Many lenders only offer construction loans to owners with fixed cost contracts.
Home loans often come with fees and borrowers should always keep an eye out for them. When it comes to construction loans, they might want to consider additional like progressive drawing fees, valuation, and inspection fees too.
Construction loans are a popular way to finance a home build as they allow the flexibility and financial leeway many homebuilders need during the construction stage.
While there use appears to have waned in recent years, that’s likely a reflection on the broader housing and economic environment. As the table below shows, the number of owner-occupiers taking out construction loans dropped amid Reserve Bank of Australia (RBA) rate hikes and broadly rising house prices in early 2023.
The rise in the number of owner-occupiers taking out loans to fund construction in 2020 and 2021 may relate to the introduction of the $25,000 HomeBuilder grant in June 2020, it’s reduction to $15,000 in January 2021, and its repeal in March 2021.
When applying for a construction loan, lenders usually require more than what you'd need to hand over during a typical home loan application, as they need to assess both your financial position and the building project itself. Some key documents include:
Contract of sale
Before you break ground on your building project, you'll need to own that ground. Your lender will want the contract of sale related to your land purchase or proof of ownership.
Council approved plans
Your lender will want evidence that your proposed project has received the necessary council approvals to avoid financing something that could later be rejected.
Building contract
This must be signed and dated. It should detail the building plans, total cost, and a progress payment schedule that aligns with how the lender will release funds in stages.
Builder’s credentials and insurance details
Typically you'll need to provide proof of Builders' Risk Insurance and your builder's Public Liability Insurance. Some lenders also ask for your builder's license details.
Construction loans tend to have higher interest rates than traditional principal & interest (P&I) home loans. This is largely due to three factors:
Home loans with interest only repayments typically represent higher risk for a lender
A person making interest only repayments isn't paying off their debt, after all.
Homes under construction also present more risk
Much of the asset used as security on the loan (the property) doesn't exist yet, and complications could arise as it's built.
It can hard to determine your final loan-to-value ratio (LVR)
Complications or cost blowouts could reduce the equilibrium between your deposit and the value of the home, which can increase a lenders' risk.
Various fees associated with construction loans may also be higher than those of traditional mortgages. The valuation fee, for example, might be higher as the valuer must assess the home's worth at each stage of construction.
There are a few things to weigh up when it comes to building a home versus buying an existing one, not least of which are the considerations that come with taking out a construction loan.
Smaller repayments
Lenders dish out money for each step of construction, meaning you only pay interest on the amount used at a given point in time. Additionally, construction home loan repayments are generally interest only during the construction process.
Protection at each stage
Construction loans are usually dished out in stages, with the lender and valuer assessing work at each stage. More eyes watching can provide some protection from dodgy work.
Less stamp duty and more grants
Stamp duty payable depends on a property's purchase price, and since vacant land is typically cheaper than an existing house, a home builder will likely pay less stamp duty. On top of that, many state governments offer stamp duty concessions and grants to those building new homes.
Challenges of building
There're lots of unknowns associated with building a home. Poor weather, dodgy tradies, and material shortages can draw out the process and add to costs and the final product might not be what you envisioned when you started.
Higher rates
Interest rates are typically higher on construction loans. If costs blow out, that can also result in a higher LVR than expected.
More overall interest paid
If you make interest only repayments during the construction phase and your home loan repayments later roll into principal and interest, you'll ultimately pay more interest than if you made principal & interest repayments from the get-go.
Construction loans usually only demand interest only repayments while the build process is underway, meaning repayments are lower during this phase.
Once construction ends, the home loan might be transformed into a regular mortgage with principal and interest payments. This means you will start to pay down the principal of the loan, which could see your regular repayments jump significantly.

When entering a construction contract, you and the builder need to decide between a fixed price or a cost plus arrangement. Each has its benefits, depending on your priorities and financial situation.
Pros of a fixed price contract:
Predictable costs
A fixed price contract sets a predetermined cost for the entire project. This is ideal for those with a tight budget, as it provides certainty and helps avoid unexpected expenses.
Risk management
The builder bears the risk of cost overruns, which can provide peace of mind to homeowners. Any additional costs due to delays or material price increases are typically the builder's responsibility.
Pros of a cost plus contract:
Flexibility
A cost plus contract covers the actual costs of materials and labor plus an agreed-upon fee or percentage for the builder. This can be advantageous if you want the flexibility to choose higher quality or custom materials throughout the project.
Potential for higher quality
If budget flexibility allows, you can opt for better materials and workmanship, potentially leading to a higher quality finished product.
Fixed price contracts are generally better for those who need strict budget control, while cost plus contracts can be more suitable for those who prioritise customisation and are willing to invest in higher quality materials and finishes.
Remember, however, that lenders often prefer fixed price contracts and some won't fund a build entered into under a cost plus contract.
Structural renovations involve substantial modifications to the core framework of your home. These changes can significantly impact the layout, functionality, and stability of the structure. They usually require detailed architectural plans, building permits, and professional oversight to ensure compliance with building codes and regulations.
Non-structural renovations are primarily cosmetic and focus on enhancing the appearance and comfort of your home without altering its fundamental structure.
Many lenders will allow you to tap into the equity you’ve built in your current home to fund the construction of your next home.
Equity is the portion of a property's value that isn't funded by a home loan. For example, if you own a home worth $700,000 and have a $500,000 mortgage, you'll have $200,000 of equity.
Equity can often be used as a deposit on a construction loan.
One of the main things to consider when accessing equity is that you'll be eating into your financial buffer if things go wrong. For instance, if the property market were to experience a downturn, you could find yourself in negative equity – which means you owe your lender more than your home is worth.
Another consideration is the fact that you could end up needing to meet repayments on two mortgages, which could take up a significant chunk of your household budget.
Yes, a construction loan can be used to fund a renovation.
However, the renovations in question may need to be substantial to meet lenders' criteria. A substantial renovation could include projects like a complete backyard remodel with the addition of a pool, deck, and other features, adding another storey to a home, or undergoing an extension.
Some lenders instate a minimum loan size for a construction mortgage. If your renovations are expected to cost less than the minimum loan loan size, your project might not qualify for a construction home loan.
Construction loans can be harder to qualify for than standard home loans due to the added risks and complexity. Lenders typically require detailed building plans, a signed contract with a licensed builder, and sometimes a higher deposit. A strong credit score and stable income can improve your chances.
In most cases, a standard home loan isn’t suitable for construction because it doesn't accommodate progress payments. Construction loans are specifically structured to fund each building phase, allowing you to pay only interest on the drawn funds until the build is complete.
Most major Australian lenders, including banks like Commonwealth Bank, ANZ, Westpac, and NAB, as well as some smaller banks, credit unions, and non-bank lenders offer construction loans. Each lender has unique criteria and interest rates, so it’s a good idea to compare options.
A progress payment is a payment made to the builder at a set stage of construction, drawn from the construction loan. Lenders release these payments directly to the builder after inspecting the work completed at each stage, such as the slab, frame, lockup, and final stages.
