Construction loans are designed to fund property projects progressively rather than as one lump sum. They are commonly used for duplex, townhouse, apartment, subdivision, mixed-use, industrial and commercial developments where staged funding, project timing and exit strategy all matter.
At Formation Finance, we help structure construction loans for self-employed individuals, property investors, owner-builders and developers, covering the gap that traditional banks leave for borrowers and projects that don’t fit standard bank criteria.
A construction loan typically sits in the middle of the property development finance lifecycle, following the land loan stage and preceding residual stock finance at project completion.

Construction loans in Australia broadly split into two categories. Understanding which fits your scenario determines which lender route is most cost-effective.
| Bank Construction Home Loan | Non-Bank / Specialist Construction Loan | |
|---|---|---|
| Best for | PAYG owner-occupiers building a single home with full documentation | Self-employed, low doc, owner-builders, imperfect credit, developers |
| Loan size | $300k – $1M | $300k – $50M+ |
| Documentation | Full doc (tax returns, payslips, financials) | Full doc / Low doc / No doc options |
| LVR | Up to 95% (with LMI) | Up to 80% individual / 70% GRV developer |
| Interest rate | From ~6% p.a. | From 7.5% p.a. (individual) / 9.99% p.a. (developer) |
| Approval time | 8–12+ weeks | 48 hours indicative / 2–6 weeks to settlement |
| Owner-builder | Rarely approved | Considered case-by-case |
| Pre-sales (developers) | 60–100% debt cover required | Often nil to low presales accepted |
| Term | 30 years (12-month build period) | 12–36 months (developer) / up to 30 years (individual) |
How to choose: If your application fits major bank policy — full income documentation, clean credit, licensed builder, single home — a bank construction home loan will almost always be cheaper. Specialist construction loans exist for borrowers and projects that fall outside that box: self-employed without recent tax returns, owner-builders managing their own project, borrowers with past credit issues, foreign income earners, and developers funding multi-unit or commercial schemes.
Our construction loan solutions are designed for borrowers whose scenarios fall outside major bank policy. Common profiles include:
Construction loans are development funding facilities where the loan is usually released in stages as the project progresses. Instead of advancing the full amount upfront, funds are drawn against completed milestones such as slab, frame, lock-up, fixing and completion.
This structure helps align funding with construction progress while allowing the lender to monitor cost, timing and delivery risk throughout the project.
Construction loans are usually drawn in stages as the build progresses. Instead of advancing the full facility upfront, funds are generally released when construction reaches agreed milestones and the required supporting documents have been provided.
This type of structure is commonly used because it keeps the funding process closer to the actual pace of the build. In many cases, interest is charged on the amount already drawn, rather than the full approved facility, which can help the funding arrangement better reflect construction progress.
Lenders usually assess more than just the security property. Construction loans are often reviewed in the context of the broader project, including the build scope, total cost, requested facility, supporting documents, timeline and contingency.
They will also usually want to understand how the project is expected to move from approval to completion, and what the intended exit will be once construction is finished. A clearer and more coherent application can make the overall funding process easier to assess.
A construction loan application is usually stronger when the supporting information clearly explains the build and the funding request.
Common documents may include:
The exact requirements can vary depending on the lender and the project, but incomplete or inconsistent documents are one of the most common reasons construction loan applications slow down.
Lenders usually assess construction loans by looking at the project feasibility, the GRV and LVR position, available contingency, time and cost risk, the quality of the security property and the strength of the proposed exit through sale, refinance or another pathway.
This matters because construction finance is not only about funding the build. It is also about whether the project can be completed and exited on a realistic timeline.
Where relevant, project planning and construction standards may also matter, particularly when a development needs to align with broader Australian building requirements such as the National Construction Code.
Construction loans are structured to fund construction projects progressively. Instead of receiving the full loan upfront, funds are distributed through progress payments monthly or per stage. This schedule outlines when and how much of the total loan amount will be released at each phase of construction. During the build, interest is only charged on the funds that have been drawn, not the entire loan amount—making construction loans a cost-effective way to manage cash flow. We also offer private construction loans for developers and builders seeking faster approvals and more flexible terms.
Yes, absolutely — duplex construction projects are commonly funded through both standard construction loans and low doc construction loans, depending on your needs and documentation.
If you’re a developer or investor building a duplex, non-bank lenders can offer more flexible terms and faster approvals than traditional banks. Whether it’s for subdivision, house-behind-house, or side-by-side dual occupancy, we can tailor construction loan solutions to match the scale and timeline of your project.
Approval times can range from a few days to a few weeks, depending on the complexity of your project and the documentation provided. Our streamlined process ensures faster decisions compared to traditional banks.
Not always. While some projects benefit from having pre-sales in place, especially for larger multi-unit developments, we assess each application individually. Our flexible approach means we may be able to offer funding without pre-sales, depending on the strength of the project and the developer’s experience.
Bank construction home loans suit borrowers with full income documentation, PAYG income or established business financials, and a single property being built. Pricing starts around 6% p.a. and the loan typically converts to a 30-year home loan after construction. Non-bank construction loans are designed for borrowers or projects that don’t fit standard bank policy — self-employed, low doc, owner-builder, multi-unit developers, or scenarios needing faster approval. Pricing is higher (7.5%–12%+ p.a.) and terms are shorter (12–36 months).
Yes. For self-employed borrowers without recent tax returns, low doc construction loans accept income declarations supported by BAS, bank statements or accountant letters. No doc construction loans are available for asset-backed scenarios where the project feasibility, security and exit strategy carry the assessment without income verification. Both options price higher than full doc to reflect the additional risk.
Owner-builder construction loans are available but more restrictive than standard builder-led construction loans. Most lenders cap LVRs at 50–70% (vs 80%+ with a licensed builder), require detailed cost estimates and HBCF/HBWI insurance, and prefer borrowers with relevant construction or trade experience. Banks rarely approve owner-builder scenarios above small renovations.
For owner-occupier and small investor construction loans, minimum deposit is generally 20% (LVR up to 80%); some lenders accept 10% with lenders mortgage insurance. For developer construction loans, minimum equity contribution is typically 20–25% of total development cost on senior debt, dropping to 10–15% with mezzanine finance.
