Do you know how land purchase construction loans work?

Buying Land Before You Build

When you purchase vacant land with the intention of building townhouses, you need two types of funding rolled into one facility. The land component settles like a standard property purchase, while the construction phase releases funds progressively as each stage of the build is completed and verified.

Consider a buyer who secures a block in Auburn zoned for dual occupancy. They settle on the land using the first portion of their approved loan, then hold the title while finalising council approvals and engaging a registered builder. Once construction begins, the lender releases funds at predetermined milestones such as slab, frame, lockup, fixing, and practical completion. Between settlement and the first progress draw, the borrower pays interest only on the land portion. As each drawdown occurs, interest accrues on the total amount released so far.

How the Progressive Drawdown Structure Works

Funds are released according to a progress payment schedule that matches the building contract. Most lenders require a quantity surveyor or independent inspector to verify completion of each stage before releasing the next payment. You submit invoices from the builder, the lender arranges an inspection, and once approved, the funds transfer directly to the builder or into your nominated account if you're managing payments yourself.

The schedule typically includes five to seven drawdowns. A development application for townhouse construction in Parramatta might include earthworks, foundation, frame and roof, external cladding and windows, internal fit-out, and final completion. Each stage corresponds to a percentage of the total build cost agreed in the fixed price building contract. The lender holds back a final retention amount, usually around five per cent, until practical completion and any defect periods are satisfied.

Interest Charges During Construction

You only pay interest on the amount drawn down at each stage, not the full loan amount approved. If your land purchase was $600,000 and your construction budget is $1,200,000, you'll pay interest on $600,000 after settlement. Once the first progress payment of $200,000 is released, your interest calculation shifts to $800,000. This continues until the full $1,800,000 is drawn.

Most construction loans offer interest-only repayment options during the build phase. This keeps your monthly outgoings lower while you're funding a project that isn't yet generating rental income or ready for occupation. Once construction finishes and the loan converts to a standard home loan or investment loan, you switch to principal and interest repayments unless you negotiate an extended interest-only period.

What Lenders Need Before Approving the Loan

Approval depends on council plans, a fixed price building contract with a registered builder, and proof that the project is viable. Lenders want to see that the development application has been approved or is very close to approval, that the builder holds appropriate licenses and insurance, and that the contract price aligns with the loan amount you're requesting.

In Granville, where blocks suitable for townhouse development are tightly held, lenders also assess whether the land value supports the total project cost. If you're borrowing 80 per cent against the combined land and construction value, the lender needs confidence that the completed townhouses will be worth more than your total debt. They'll often require a pre-construction valuation that estimates the end value based on comparable sales of similar newly built townhouses in the area.

Your borrowing capacity plays a role too. Lenders assess whether you can service the interest during construction and the full repayment once the build is complete. If you're planning to sell one townhouse and live in the other, they'll factor in the expected sale price and your ongoing income. If you're keeping both as investments, they'll assess rental income at a discounted rate, usually 80 per cent of market rent.

Fixed Price Contracts and Cost Certainty

A fixed price building contract locks in the total construction cost, which protects both you and the lender from budget blowouts. Lenders will approve a loan amount based on this contract, and any cost overruns become your responsibility unless you can renegotiate or secure additional funding.

Cost plus contracts, where you pay the builder's actual costs plus a margin, are harder to finance because the final amount is uncertain. Most mainstream lenders won't approve construction funding without a fixed price agreement. If your builder proposes variations during the build, you'll need to cover those costs separately or seek approval from the lender to increase the loan, which isn't guaranteed.

Owner Builder Challenges

If you're planning to act as an owner builder rather than engaging a licensed contractor, your loan options narrow significantly. Lenders view owner builder projects as higher risk because there's no third-party accountability for quality or timelines. The few lenders who do offer owner builder finance typically require larger deposits, charge higher interest rates, and impose stricter progress inspection requirements.

You'll also need to manage payments to sub-contractors like plumbers and electricians yourself, which means maintaining detailed records and submitting invoices for each drawdown. In practice, most buyers pursuing townhouse construction in Sydney use a registered builder under a fixed price contract to keep the project financeable and reduce personal liability.

Timeline Requirements and Build Commencement

Most lenders require you to commence building within a set period from the loan approval date, typically six to twelve months. If you settle on land but delay construction beyond this window, the lender may reassess your loan or withdraw the construction funding component, leaving you with land and no approved facility to build.

This is particularly relevant in areas like Merrylands, where council approval processes can stretch longer than expected. If your development application is delayed or you encounter disputes with adjoining owners, the clock is still running on your lender's commencement deadline. Staying in close contact with both your builder and your broker during this phase keeps everyone aligned and allows for extensions to be requested before the deadline passes.

Converting to a Permanent Loan After Completion

Once construction reaches practical completion and you've received final sign-off from the certifier, the loan converts from a construction facility to a standard mortgage. The lender conducts a final valuation to confirm the completed townhouses meet the expected value, then adjusts your loan structure accordingly.

At this point, you'll typically move from interest-only payments to principal and interest, unless you've arranged an ongoing interest-only period. If you're holding the townhouses as investments, you might refinance into a longer interest-only term to maximise cash flow. If you're living in one and renting the other, you'll likely split the loan so the investment portion remains interest-only while the owner-occupied portion shifts to principal and interest.

If you're planning to sell one townhouse to reduce debt, the lender will require a partial discharge once that sale settles. The remaining loan stays in place against the property you're keeping. This is a common strategy in Parramatta, where buyers use the equity from one completed townhouse to fund the next development or reduce their overall exposure. You can explore refinancing options at this stage to secure a lower rate or access better loan features now that the construction risk has been removed.

Progressive Drawing Fees and Costs During the Build

Lenders charge a progressive drawing fee each time they release funds and arrange an inspection. This fee typically ranges from $300 to $500 per drawdown, which adds up over five to seven stages. Some lenders cap the total fees or bundle them into a single upfront charge, while others apply them per progress claim.

You'll also pay interest on the loan from the day the land settles, even though construction hasn't started. Holding costs during this period include interest, land tax if applicable, and ongoing council rates. If there's a six-month gap between settlement and the first slab pour, you're funding those months out of pocket or from rental income if the block has an existing dwelling you're retaining temporarily.

Call one of our team or book an appointment at a time that works for you to discuss how a land and construction package fits your project, what deposit you'll need, and how the drawdown schedule aligns with your builder's timeline. We work through your council approval status, your builder's contract, and your timeline to make sure the loan structure supports the build from land settlement through to final completion.
