Construction Loans for Multi-unit Sites: What Not to Do

Buying land in Helensvale to build multiple dwellings requires a different type of finance to a standard home loan.

You'll need what's called a construction loan with development capacity, and the way these work is quite different to the lending most people are familiar with. The loan is drawn down in stages as the build progresses, and lenders assess the project viability as well as your own financial position.

How Construction Finance Works for Multi-unit Projects

A construction loan for a multi-unit site is structured around progressive drawdown. You don't receive the full loan amount upfront. Instead, the lender releases funds at agreed stages as the build reaches key milestones, such as slab pour, frame complete, lock-up, and practical completion. Interest is charged only on the amount drawn down at each stage, not the total approved amount.

This structure protects the lender and keeps your initial holding costs lower than if you were servicing the full loan from day one. However, it also means you need to work with a registered builder who can provide a fixed price building contract and a clear progress payment schedule that aligns with the lender's drawdown process.

What Lenders Assess Before Approving Development Finance

Lenders look at the project itself, not just your income and deposit. They want to see council approval or at least a strong likelihood that your development application will be approved. They'll assess the land value, the proposed build cost, and the end value of the completed units. If the numbers don't stack up or the project carries too much risk, the loan won't proceed regardless of your personal financial strength.

In our experience, buyers who secure council plans before applying for finance have a much smoother approval process. Lenders are more confident when they can see exactly what's being built and that it meets local zoning and planning requirements.

The Cost Plus Contract Trap

One issue that can derail a multi-unit construction loan application is choosing a cost plus contract instead of a fixed price building contract. With a cost plus arrangement, the final build cost isn't locked in, which means the lender can't accurately assess the total project value or your equity position. Most lenders require a fixed price contract before they'll release construction funding.

Consider a buyer purchasing a 1,000 square metre block in Helensvale near the Westfield shopping precinct, intending to build three townhouses. The land costs $650,000, and the builder quotes $900,000 for the build under a cost plus contract. The lender declines the application because the contract doesn't provide certainty around the final cost. The buyer goes back to the builder, negotiates a fixed price contract at $920,000, and the loan is approved within two weeks. The slightly higher build cost was worth the certainty it provided.

Progressive Drawing Fees and Holding Costs

Each time the lender releases funds during the build, they charge a progressive drawing fee. This fee covers the cost of sending a valuer or building inspector to verify that the stage of work has been completed to the required standard. The fee is usually between $300 and $500 per drawdown, and there are typically five to six drawdowns over the course of a multi-unit build.

You'll also need to budget for interest-only repayment options during construction. Most lenders allow you to pay interest only on the drawn amount until the project is complete, which keeps your monthly costs manageable while you're not yet generating rental income or sale proceeds. Once the build is finished, the loan typically converts to principal and interest repayments, or you may choose to sell the units and repay the loan in full.

Owner Builder Finance and Why It's Harder to Access

If you're planning to act as an owner builder rather than hiring a registered builder, your finance options become much more limited. Most mainstream lenders won't provide construction funding for owner builder projects involving multiple dwellings because the risk is too high. Without a licensed builder overseeing the project, there's no professional accountability for defects, delays, or cost overruns.

There are specialist lenders who offer owner builder finance, but the interest rates are higher, the deposit requirements are steeper, and the loan terms are stricter. Unless you have substantial construction experience and can demonstrate that you've managed similar projects before, securing funding as an owner builder for a multi-unit site is difficult.

What Happens If You Don't Commence Building on Time

Most construction loans include a condition that you must commence building within a set period from the disclosure date, usually six to twelve months. If you don't start construction within that window, the lender can withdraw the approved funding or charge a higher interest rate on the land component of the loan.

This is particularly relevant in Helensvale, where development applications can take longer than expected if your site is near sensitive areas like the Coombabah Lake Conservation Park or if council requests design changes to fit with the area's growing residential character. If you're still waiting on final council approval when your commencement deadline arrives, you may need to renegotiate your loan terms or risk losing your construction funding.

How the Progressive Payment Schedule Is Structured

The progress payment schedule in your building contract needs to match the lender's drawdown stages. If the builder expects payment at six stages but the lender only releases funds at five, you'll need to cover the gap yourself or renegotiate one of the schedules.

Typical drawdown stages for a multi-unit project include deposit, base or slab, frame and roof, lock-up, fixing, and practical completion. The builder invoices you at each stage, you submit the invoice to the lender along with any required progress inspection reports, and the lender releases the funds directly to the builder. You won't handle the money yourself in most cases.

Choosing Suitable Land for a Multi-unit Build

Not all land in Helensvale is zoned for multi-unit development. You need to confirm that the block you're buying allows for the number of dwellings you plan to build, and that it meets minimum lot size, frontage, and setback requirements under the local planning scheme.

Blocks near the Helensvale train station or along the main commercial corridors are more likely to support higher density development, while residential pockets further west may be limited to single dwellings or duplexes. Before you sign a contract to purchase land, it's worth engaging a town planner to confirm what you can realistically build on the site.

When to Consider a Land and Construction Package

Some developers and builders offer land and construction packages where the land and build are sold together as a single transaction. These can be appealing because the builder has already worked through the design and approval process, and the lender sees less risk in a packaged deal.

However, you'll usually pay a premium for the convenience, and you'll have limited control over the build specifications and finishes. If you're buying land separately and managing your own development application, you have more flexibility to design the project to suit the local market and maximise the end value of the units. For someone looking at construction loans with a clear vision for what they want to build, a separate land purchase often makes more sense.

How Lenders Assess Your Capacity for Development Finance

Your borrowing capacity for a multi-unit construction loan is calculated differently to a standard home loan. Lenders consider your ability to service the loan during construction, when you're paying interest only on the drawn amount, as well as your ability to service the full loan once construction is complete and the loan converts to principal and interest.

They'll also assess whether you have enough cash flow to cover holding costs like council rates, insurance, and any shortfall between the drawn amount and the stage payments due to the builder. If you're relying on pre-sales or rental income from the completed units to service the loan, the lender will want to see evidence that the end values or rental yields are realistic for the Helensvale area.

If your financial position is more complex, such as being self-employed or holding multiple investment properties, working with a mortgage broker in Helensvale who understands development finance can make a significant difference to your approval outcome.

Final Approval and Settlement Process

Once your construction loan is approved, you'll settle on the land purchase first. The lender advances the land portion of the loan, and you take ownership of the site. From that point, you have a set period to submit your building contract, finalised council plans, and any other documentation the lender requires before they'll release the first construction drawdown.

If there are delays in securing council approval or finalising the building contract, you'll be paying interest on the land component without being able to progress the build. This is why timing matters, and why it's important to have all your approvals and contracts as close to ready as possible before you settle on the land.
