A Turning Point for Modular Home Financing
The Commonwealth Bank of Australia (CBA) has launched a transformative policy set to reshape how Australians finance modular and prefabricated homes. Beginning 10 July 2025, CBA will uplift its prefabricated housing policy, offering significantly improved financing terms for customers working with CommBank Assessed Manufacturers.
These changes mark a bold move to support Australia’s growing interest in off-site construction, address housing supply shortages, and bring financing for modular homes into the mainstream. Whether you’re a first-time buyer or developer, this article explores the fine print, key benefits, risks, and long-tail FAQs around CBA’s modular home loan policy.

1. What Are Modular and Prefabricated Homes?
Prefabricated homes (also called prefab homes) are dwellings constructed in a factory and then transported to the final site for permanent installation. They come in two primary types:
- Modular homes: Fully built-in modules or sections offsite, then assembled on land.
- Kit homes: Pre-cut materials are prepared in a factory, then delivered and assembled onsite.
Why Are Prefab Homes Gaining Popularity?
- Speed: Off-site construction can take 10–12 weeks, compared to 18+ months for traditional builds.
- Cost efficiency: Reduced labour and weather-related delays.
- Sustainability: Factory environments reduce waste and allow better energy efficiency.
- Quality control: Consistent production standards.
2. Key Changes to CBA’s Modular Home Loan Policy (From 10 July 2025)
CBA is simplifying how prefab home buyers access funding during the construction process. The highlight of the change is enhanced progress payments during offsite build stages, particularly when using accredited builders.
New Funding Thresholds:
| Customer Type | Maximum Available Before Land Affixture |
|---|---|
| All customers | 120% of land value (less land debt) OR 60% of contract price |
| With CBA Assessed Manufacturer | 150% of land value (less land debt) OR 80% of contract price |
Whichever is lower applies.
If your land is valued at $300,000 and you owe $160,000 on it, 120% of land value less debt allows for up to $200,000 to be released in early-stage funding. With an assessed manufacturer, this can increase to $250,000, if it falls under the 150% land value or 80% contract price threshold.
3. Who Are CommBank Assessed Manufacturers?
These are prefab builders that meet CBA’s rigorous evaluation process. To qualify, a builder must demonstrate:
- Satisfactory financial performance
- Onshore manufacturing capabilities
- Factory inspection completed successfully
This vetting allows CBA to offer better financial terms by reducing lender risk. It also protects customers from unreliable builders.

4. Benefits for Home Buyers
Increased Early Funding
With up to 80% of contract value accessible before land affixture, you won’t have to self-fund the majority of your build. This helps bridge the financing gap that has traditionally hampered prefab adoption.
Faster Project Completion
Since offsite construction is quicker, and funding is smoother, buyers can move in faster—sometimes within months.
Support for Contracts up to $1.5M
The program supports prefab build contracts up to $1.5 million—covering a large portion of Australia’s mid-market housing.
Transparent Valuation and Inspection
CBA conducts a valuation and final inspection to ensure the prefab home is affixed and connected to services before releasing final funds.
5. Frequently Asked Questions (FAQs)
Q: Is a prefab loan different from a normal construction loan?
Yes and no. It’s structured as a standard construction loan, but with modified thresholds to release funds earlier—before the home is affixed to land.
Q: What if I go with a builder who isn’t accredited?
You’ll be limited to 120% of land value (less debt) or 60% of the contract price in early-stage funding. This could mean needing to front-load more capital yourself.
Q: What happens if the builder goes bankrupt before land affixture?
This is a key risk. The land is the sole security until the home is affixed. If the builder fails mid-way, you may face negative equity and still owe loan repayments.
Tip: Consult legal and financial advisors about insurance protections and risk mitigation.
Q: How do I know if my prefab builder is assessed by CBA?
Ask the builder directly, or contact CBA for their list of approved manufacturers. Only builders who pass the inspection and financial check process qualify.
Q: Can I get a loan if my build is over $1.5M?
You can—but progress payments won’t be released until the home is permanently affixed to the land and connected to services.
Q: What documents do I need?
You’ll need:
- Fixed-price contract (under $1.5M)
- Valuation confirming affixture plan
- Standard construction loan documentation
- Evidence of land ownership or purchase
6. CBA’s Partnership with prefabAUS
In a major show of commitment to the sector, CBA became the first bank to join prefabAUS—Australia’s peak body for off-site construction.
They are also sponsoring a standard-form contract specifically for prefab builds, similar to those used in traditional home construction. This aims to further de-risk prefab lending and standardise the process for banks and buyers.
“Overseas in countries like Sweden, 80% of homes are factory-built,” said Mike Vacy-Lyle, CBA Group Executive. “We expect prefab in Australia to follow a similar growth trajectory.”
7. Timeline of Support for Modular Builds
| Date | Development |
|---|---|
| 2017 | CBA begins funding prefab projects like Modscape |
| Nov 2024 | Pledges made at Treasurer’s Investor Roundtable to boost MMC financing |
| Jan 2025 | CBA joins prefabAUS and announces lending policy overhaul |
| 10 July 2025 | Enhanced prefab loan policy goes live |
8. Real-World Example: Tim’s Prefab Journey
Scenario from the CBA Info Sheet
- Land value: $300,000
- Land loan: $160,000
- Build cost: $350,000
- Upfront stages claimed: $200,000 (under 120% of land value rule)
With a CBA-assessed builder, Tim could access up to $250,000 earlier in the build, providing smoother cash flow and less personal capital injection.
9. What to Watch Out For (Risks and Considerations)
- Security during build: Land is used as the sole collateral before the home is affixed.
- Builder risk: If your builder collapses mid-build, you may not recover released funds.
- State-by-state legal protections vary: Some states have stronger consumer protections.
- Insurance: Not all builds are covered by default. Investigate builder warranty insurance options.
- Valuation bottlenecks: Final inspection is mandatory before final funds are released.
A New Era for Home Builders
CBA’s changes signal a serious commitment to off-site construction and a pragmatic step toward easing Australia’s housing crisis. By reducing the funding burden on homeowners and accrediting builders, the new policy enables more Australians to choose faster, more affordable housing options through modular builds.
This is a rare case where innovation in banking policy meets real-world housing need—offering both security and speed.
