Get Commercial Construction Finance From Our 60+ Strong Australian Lender Panel

💡

"Most major banks won't fund construction for specialist property types like childcare centres or veterinary clinics — they don't have the internal expertise to assess them. That's exactly where our non-bank and specialist lender panel fills the gap. We've arranged construction finance for property types that three other brokers had already told the client were 'unfundable.'"

What Affects Your Construction Loan Rate

Construction loan rates of [sbp_rates_construction_range] vary based on several factors. Here's what determines where you sit within that range:

Purpose of the build Owner-occupier builds typically attract lower rates than investment builds because lenders see lower risk when the borrower will occupy the property.
Builder experience First-time builders generally pay more than experienced operators with a proven construction track record.
Pre-lease or pre-commitment Investment builds with a signed lease in place before construction starts will attract better rates and higher LVR than speculative builds.
Project location Metro construction projects generally attract better rates than regional or rural builds. Some lenders won't fund outside capital cities.
Loan size Larger projects ($2M+) may attract volume discounts. Very small builds under $500K have fewer lender options.
Contract type Fixed-price building contracts are preferred by lenders. Cost-plus contracts typically attract higher rates due to budget uncertainty.
💡

"We consistently see clients save 0.5–1% on their construction loan rate simply by switching from a cost-plus to a fixed-price building contract before we submit the application. It's one of the first things we check."

Nadine Connell, Commercial Finance Broker, Smart Business Plans, authorised representative of Loan Market Group (CR 553930)

Start Early: Construction loan approvals take 4–6 weeks — begin the application process during your planning or DA stage.
Interest Savings: You only pay interest on funds drawn down, not the full loan amount. This saves significant cost during the build phase.

The 5 Stages of a Commercial Construction Loan Drawdown

Unlike a standard commercial property loan where you receive the full amount at settlement, construction finance is released in stages as your build progresses. Each drawdown is verified by an independent inspection before the lender releases funds.

How Progress Drawdowns Work

1 Builder completes a stage of work
2 They submit a progress claim
3 Lender sends an independent valuer
4 Once verified, funds are released
1 ~15% Base / Slab Stage Site preparation, excavation, footings, and concrete slab pour.
What's completed: Site cleared, footings poured, slab laid, plumbing rough-in beneath slab.
What the valuer checks: Slab dimensions match approved plans, concrete quality, drainage and plumbing positioning.
2 ~20% Frame Stage Structural skeleton goes up — steel or timber framing, roof trusses, and supports.
What's completed: Wall framing erected, roof trusses installed, structural bracing in place.
What the valuer checks: Framing matches engineering specifications, structural integrity, compliance with approved plans.
3 ~20% Lock-Up Stage Building is weatherproof and secure — external walls, roof, windows, and doors installed.
What's completed: Roof sheeting or tiles, external cladding, windows and external doors fitted, building is weathertight.
What the valuer checks: Building is fully enclosed, all external elements match specifications, no water ingress issues.
4 ~30% Fit-Out / Fixing Stage All internal work — electrical, plumbing, plastering, cabinetry, flooring, and specialist fitout.
What's completed: Internal walls, electrical and plumbing fit-off, plastering, painting, flooring, cabinetry, specialist fitout.
What the valuer checks: Internal works match plans, quality of finishes, specialist requirements completed to specification.
5 ~15% Completion / Practical Completion Occupancy certificate issued. Construction loan converts to a standard long-term loan.
What's completed: All works finished, landscaping, driveways, occupancy certificate issued by council.
What the valuer checks: Final "as completed" valuation confirms property value matches or exceeds the original "as if complete" estimate.
What happens next: Your construction loan converts to a standard term loan (typically 15–30 years). If arranged upfront, conversion happens automatically with no new application required.

Interest During Construction

You only pay interest on the funds that have actually been drawn down — not on the total approved loan amount. In the early stages of construction, your monthly interest cost is significantly lower than it will be at completion.

💡

"The drawdown stage most clients don't prepare for is the progress inspection. If your builder hasn't completed enough work to satisfy the lender's valuer, the draw gets delayed — and your builder stops work. We brief every client on exactly what each lender's valuer looks for at each stage so there are no surprises."

Progressive Drawdown Timeline

How This Type of Loan Works

Construction loans in Australia are typically interest-only during the build phase, with funds released progressively as each stage is completed. You only pay interest on the amount drawn down, not the full approved amount.

Most lenders require progress inspections at each stage before releasing funds. The standard stages are: slab, frame, lockup, fixing, and completion.

Current Market Rates (2026)

  • Construction phase: 6.60% - 15.00% p.a.
  • End loan (owner-occupier): 5.95% - 10.05% p.a.
  • End loan (investment): 6.10% - 10.20% p.a.
  • Maximum LVR: 50% - 70%
  • Interest-only available during construction

Cost Considerations

  • Allow 10-15% contingency in budget
  • Factor in council fees and permits
  • Include landscaping and external works
  • Budget for interest during construction
  • Consider professional fees (surveyor, certifier)

Client Story

From 12 Years of Rent to Building Their Own Warehouse

Business owner at commercial warehouse built with construction finance arranged by Smart Business Plans
$1,200/mo Less than rent
$2.4M Current valuation
14 months Slab to completion
70% LVR approved

Tariq ran a logistics business on the Gold Coast for 15 years. Good revenue. Loyal staff. Long-term contracts. But every year, the same conversation with his landlord ended the same way — another rent increase, another five-figure hit to his bottom line.

"I'd been paying $9,500 a month in rent for a warehouse that didn't even suit us properly," Tariq told us. "The roller doors were too low for our new trucks. We needed a cool room. Every time I asked about modifications, the landlord said no."

Tariq had spoken to his bank about building his own 2,000m² warehouse. Despite 15 years of profitable trading, they declined. The reason: no prior commercial construction experience. His accountant suggested a second bank. Same result.

Finding the Right Lender

When Tariq called us, he was frustrated and close to signing another five-year lease. We reviewed his financials and saw exactly what the banks had missed — a business with consistent revenue, strong contracts, and a genuine operational need for purpose-built premises.

We identified a second-tier lender with appetite for first-time owner-occupier builds in the logistics sector. We presented Tariq's long trading history and existing lease costs as serviceability evidence — essentially showing the lender that Tariq was already "making the repayments" through rent, but building nothing.

The Build

We secured approval at 70% LVR on a $1.8 million construction cost. Tariq's build ran 14 months across five drawdown stages. We coordinated every progress inspection and managed each drawdown release so his builder was never waiting on funds.

At completion, the construction loan converted automatically to a 25-year term loan — no new application, no new valuation, no disruption.

The Result

Tariq's monthly mortgage repayment is $1,200 less than the rent he was paying — for a warehouse he owns, designed exactly for his business. The cool room is built in. The roller doors fit his trucks. And every repayment builds equity in an asset now valued at $2.4 million.

"I wish I'd done it five years earlier. The amount of rent I paid that landlord — I try not to think about it. But at least now, every dollar goes into something that's mine."

Frequently asked questions

Most of the commercial construction loans from our extensive Australian lender panel require a 20-30% deposit of the total project cost, though this can vary based on your experience and the project specifics. If you’re an owner-occupier of the construction project, some lenders may accept a deposit as low as 15% if you have strong financials.

The deposit must cover both land (if not already owned) and construction costs. First-time commercial builders typically need higher deposits around 30-35%, while experienced builders with proven track records may negotiate lower requirements. Remember, your deposit also needs to cover stamp duty, legal fees, and initial construction costs before the first drawdown.

Your progress payments in commercial construction loans are set to be released at predetermined construction milestones, typically: slab down (15-20%), frame stage (20-25%), lockup stage (35-40%), fixing stage (20-25%), and practical completion (10-15%). Each drawdown requires an independent valuation confirming the required work has been completed.

Unlike residential construction, commercial projects can be more flexible around the drawdown schedule based on contractor payment terms. The key is making sure your cash flow aligns with these staged payments, as you’ll need to cover any gaps between contractor invoices and loan drawdowns.

Yes, commercial renovation loans or refurbishment finance is available from our lender panel for upgrading existing commercial properties.

These loans typically offer 70-80% of the total project value (combining the existing property plus renovation costs). Lenders will assess the current property value, renovation plans and scope, and projected value of the completed renovation. Major structural changes require detailed plans and council approvals, while cosmetic upgrades may have simpler approval processes. Commercial Interest Rates are usually 0.5-1% higher than standard commercial mortgages but lower than unsecured business loans.

Commercial construction loan interest rates are typically  0.75-2.00% higher than standard commercial property loans due to the increased risk. Current rates range from [sbp_rates_construction_range] depending on your experience, finances, LVR, and the complexity of the project.

One key feature to understand is that interest is only charged when you drawn down funds – it’s not charged on the full facility limit from day 1. This can significantly reduce costs during early construction stages. Most construction loans transition to standard commercial rates upon project completion which often means a saving of 1.00-2.00% annually, post-construction.

Of your project costs overrun, you’ll need to notify the lender immediately. This will usually mean a reassessment of the project. What happens next will be deetermined by the assessment but might include providing additional equity (most common), negotiating a construction loan top-up if the updated valuation supports it, securing mezzanine funding for the shortfall, or scaling back non-essential project elements.

As experienced commercial finance brokers, we always recommend a 10-15% contingency buffer in your original application. Lenders may approve increases up to 10% without full reapplication if you have strong financials and the project remains viable.

While fixed-price contracts significantly strengthen your application and are preferred by most lenders, cost-plus contracts are acceptable for experienced developers with strong track records.

Fixed-price contracts provide certainty for both you and the lender, which normally means you’ll get better loan terms and lower deposit requirements. If you choose to use a cost-plus arrangement, expect to provide detailed quantity surveyor reports, larger contingencies (15-20%), and potentially some personal guarantees. Some lenders specialise in cost-plus construction loans, but be prepared to pay a premium rate.

Commercial construction loan approvals typically take between 4 and 8 weeks from application to unconditional approval. This is significantly longer than standard property loans, and varies based on the complexity and value of your project.

The timeline often includes:

  • initial assessment (3-5 days),
  • valuation and quantity surveyor review (7-10 days),
  • credit assessment (5-7 days),
  • legal documentation review (7-10 days),
  • final approval (3-5 days). 

Fast-track options exist for experienced developers with complete documentation which can reduce the approval timeframe to 3 weeks or less. We advise clients to start the application process during the planning/DA stages to ensure funds are ready when construction begins.

Yes, investment construction loans are available for ‘build-to-lease’ commercial projects.

Our lenders typically require a signed lease agreement, or some form of strong evidence of tenant demand before approving funds. A pre-lease agreement can significantly strengthen your application and can actually reduce deposit requirements to 20-25% in some cases. Without pre-commitments, expect to need to be able to provide a 30-35% deposit. The loan structure usually includes interest-only payments during construction which helps with cash flow, converting to principal and interest once tenanted and generating income.

Commercial construction loans require extensive professional documentation:

  • quantity surveyor report outlining costs and progress payment schedule ($2,000-5,000),
  • independent valuation showing “as if complete” value ($1,500-3,000),
  • environmental site assessment for previously developed land ($2,000-8,000),
  • structural engineering reports for complex projects ($3,000-10,000), and
  • geotechnical reports for ground conditions ($2,000-5,000). 

You’ll also need a council-approved development application (DA), as well as you building contracts and architectural plans. 

We advise clients to budget about $15,000-30,000 for all professional reports on typical projects.

Owner-occupier construction finance often means getting away with lower deposit requirements (15-20%), attracting better interest rates (0.5-1% lower), and getting longer loan terms (up to 30 years). This is because lenders view owner-occupiers as lower risk (because you’re invested in the property’s long-term success).

To be eligible you’ll need to occupy at least 51% of the completed space. These loans can include fitout costs, allowing you to create purpose-built facilities. Some of our lenders offer integrated facilities combining construction, equipment finance, and working capital in one package.

Understanding GST treatment is crucial for your construction project. If you’re GST-registered and constructing commercial property for business use or sale, you can usually claim GST credits on construction costs (talk to your accountant to confirm). The margin scheme may apply if you’re selling completed properties, potentially reducing your GST obligations.

During construction, you’ll pay GST on progress payments, but you can claim quarterly BAS credits, improving your cash flow. Our lenders may offer you facilities to cover GST timing differences between payment and refund if that’s required. If you plan properly upfront you could effectively reduce your required deposit by up to 10% of construction costs.

Comprehensive construction insurance is mandatory (and just good practice). Your insurance policy needs to include:

  • contract works insurance covering the building during construction (typically 0.3-0.5% of construction cost),
  • public liability insurance minimum $20 million,
  • builder’s warranty insurance where applicable,
  • professional indemnity for design professionals,
  • latent defects insurance for major projects. 

If you’re an owner-builder you’ll need additional coverage as you are assume builder responsibilities. Your insurance must be maintained throughout project with your lender noted as interested party. We advise clients to budget approximately 1-2% of construction costs for comprehensive insurance coverage.
