Buying, investing or refinancing in Brisbane's South? We can help, just get in touch here.

Thinking about building your dream home from the ground up? A construction loan could be the key to turning your building plans into reality. In this type of loan, instead of receiving the full amount upfront, funds are released in stages as the build progresses.

Knowing how a construction loan works is essential, especially with the extra planning, lender requirements, and progress payments involved.

That’s where a mortgage broker can help. An experienced Brisbane South broker, such as AE Finance Solutions, can help explain lender policies, compare suitable options, and help structure your loan correctly from the start, thus reducing delays and costly missteps.

Ready to see how it all works? Let’s break it down step by step.

What Is a Construction Loan?

A construction loan is a specialised home loan designed for people building a new property, where funds are released progressively as construction milestones are met. Instead of receiving the full loan amount upfront, the lender pays the builder in stages as the build progresses. Interest is typically charged only on the funds that have been drawn down during construction.

How Does a Construction Loan Work in Brisbane South?

Construction loans are structured differently from standard home loans. If you're building in Brisbane South, it's important to understand how these loans operate so you're financially prepared at every stage of the build.

1. How the Loan Works

Progressive drawdowns: Instead of receiving the full loan upfront, your lender releases funds in stages—known as progressive drawdowns—aligned with construction milestones.
Interest-only repayments: During the build, you typically only pay interest on the amount drawn, which helps manage cash flow while construction is underway.
Loan conversion: Once the home is finished and receives final certification, your loan usually switches to a standard principal and interest loan.

2. Construction Stages and Drawdowns

Funds are released progressively across five typical build stages. Each stage must be completed and verified before the lender releases the next payment to the builder:

Deposit / Initial Payment: Covers early works like site preparation and slab prep.
Slab/Foundation: First formal progress payment once the concrete base is poured.
Frame / Lock-up: Funding for the frame, walls, windows, and roof—securing the structure.
Fixing: Covers internal works such as plastering, cabinetry, and plumbing.
Completion: Final payment for finishing touches and final inspections.

3. Key Requirements

To access a construction loan, lenders typically require:

A fixed-price building contract with a licensed builder
Council-approved plans and specifications
The builder’s insurance certificates
A detailed budget breakdown outlining each construction stage
Satisfactory on-completion valuation to ensure the final property value supports the loan amount

4. Inspections and Valuations

After each stage, your lender may order a valuation or inspection to confirm the work is complete before releasing the next payment.
A final inspection ensures the home is fully built and compliant before your loan transitions.

What Are the Benefits of a Construction Loan?

Construction loans offer some clear advantages:

Interest savings: Pay interest only on drawn funds
Cash flow control: Manage payments in line with build stages
Tailored finance: Designed specifically for building timelines
Loan conversion: Switch to a standard mortgage post-construction

Plus, by working with a broker who understands lender policies, you can get a loan structured to suit your specific goals, especially if you're self-employed, using equity, or relying on grants.

How to Apply for a Construction Loan in Brisbane South

Here’s what you need to know about how to successfully apply for a construction loan in Brisbane South this year:

1. Secure Your Land

You’ll need to have purchased land, or be in the process of doing so, with a signed contract. Lenders won’t approve a construction loan without this.

2. Choose Your Builder and Finalise Plans

Pick a licensed builder and sign a fixed-price building contract. Your house plans must be council-approved before the lender considers your application.

3. Apply for Pre-Approval

Your mortgage broker will help you apply for conditional approval based on your income, expenses, and credit profile, just like a regular home loan.

4. Submit Construction Documents

You’ll need to provide:

Fixed-price building contract
Council-approved plans
Builder’s insurance
Detailed costings and timeline

5. Get a Valuation

The bank will conduct an “on-completion” valuation to assess the expected value once the build is done.

6. Receive Formal Approval and Sign Loan Documents

Once all checks are done, your loan is approved. You'll sign formal loan docs, and the bank sets up a drawdown schedule for payments to the builder.

7. Progress Payments and Construction Begins

The lender releases payments to the builder after each completed stage, usually after a valuer inspects and signs off on the work.

FAQs About Construction Loans

Can I use a construction loan to build on land I already own?

Yes, if you already own the land, a construction loan can be used to fund the building portion only. The lender will still require documentation such as a fixed-price contract and approved plans.

Do I need a deposit for a construction loan?

Yes, most lenders require at least a 5–10% deposit, although some may need more depending on your financial situation. Your land value or equity may be used as part of this.

How are progress payments made to the builder?

Lenders make payments directly to your builder in stages, typically after each construction milestone is complete and inspected. You may need to approve each drawdown before it’s processed.

What happens if construction costs go over budget?

If costs increase, you’ll usually need to cover the difference out-of-pocket. It’s important to include a contingency buffer in your planning.

Can I make changes to the building contract after loan approval?

Yes, but any major changes may require re-approval from the lender. This can cause delays or even risk cancellation of the loan.

Do I pay interest during the construction period?

Yes, but only on the amount drawn down at each stage. This can help reduce your repayments during the build.

What happens after construction is complete?

Once the final stage is complete and certified, your construction loan usually converts into a standard variable or fixed-rate home loan.
