Construction Loans: What Not to Do When Buying Land

Buying land to build townhouses is not the same as buying a house and land package.

You are coordinating two separate transactions, managing council approvals, and arranging progressive drawdown funding that releases in stages as construction moves forward. Miss a step in the sequence and you could face delayed settlement, additional holding costs, or a lender pulling out before construction begins.

The insight that matters most is this: your land purchase and your construction loan are assessed separately, but they must align perfectly. The land needs to settle before construction funding can be released, your development application needs council approval before most lenders will commit, and the builder you select must meet lender requirements for registration and insurance. Get any of those out of order and you will be reworking your application or paying for delays.

What Not to Do: Purchase Land Without Pre-Approved Construction Finance

Do not buy land assuming you can arrange construction funding later. Construction finance is assessed on the land value, the proposed build cost, and your ability to service both during the construction phase. If the land does not meet lender criteria for suitable land, or if the build cost pushes your total loan amount beyond what you can service, you will own a block you cannot develop.

Consider a buyer who purchases a 600-square-metre block zoned for dual occupancy, intending to build two townhouses. They secure the land with a standard home loan, assuming they can refinance into a construction facility once they have council approval. Six months later, they approach lenders with approved plans. The lender values the land at less than the purchase price because comparable sales have softened, and the loan-to-value ratio no longer supports the total funding required. The buyer now needs to inject additional equity or scale back the project.

Pre-approval for a construction loan should cover both the land purchase and the build. Most lenders will issue conditional approval based on draft plans and a building estimate, then provide full approval once you have a fixed price building contract and council plans. That sequence keeps your funding intact from land settlement through to the final progress payment.

Council Approval Delays and Lender Expiry Dates

Construction finance approvals typically require you to commence building within a set period from the disclosure date. If your development application sits with council for nine months and your approval expires, you will need to reapply. Lenders reassess your income, the property valuation, and the interest rate environment at that point. If any of those have shifted unfavourably, your loan amount or rate may change.

Factor council timelines into your application. In some municipalities, a straightforward dual occupancy approval might take three to four months. A more complex development with planning overlays or heritage considerations could stretch beyond six months. Ask your broker to structure the approval period to match realistic council timeframes, or build in a buffer that allows for reapproval without penalty.

What Not to Do: Choose a Builder Who Does Not Meet Lender Requirements

Not every registered builder qualifies for lender-approved construction funding. Most lenders require the builder to hold current registration, adequate insurance, and in some cases, membership with a recognised industry body. Some lenders will not accept owner builder finance for projects above a certain value or complexity, and others exclude builders operating under cost plus contracts because the final build cost is not fixed.

If you engage a builder before confirming they meet your lender's criteria, you may need to switch builders mid-process or find a different lender willing to accept your chosen contractor. Either option delays the project and may change your loan terms. Verify builder eligibility with your broker before signing the building contract, particularly if you are working with a smaller or newer builder, or if you are acting as an owner builder on a townhouse development.

How the Progressive Drawdown Works and Why Timing Matters

Construction funding is released in stages as the build progresses, not as a lump sum at settlement. The lender holds the total approved loan amount and releases funds according to a progress payment schedule tied to specific milestones such as slab down, frame up, lock-up, fixing, and practical completion. A progress inspection is typically required before each drawdown to confirm the stage has been reached.

You only pay interest on the amount drawn down, which keeps repayments lower during construction. Most borrowers take interest-only repayment options during the build, then convert to principal and interest once the project is complete and rental income or sale proceeds are available.

Timing becomes critical when you are building two townhouses on a single block. If the builder requests payment for stage three but the inspection is delayed, or if the lender requires additional documentation before releasing the next drawdown, the builder may pause work. Delays at any stage push out the completion date, extend your interest-only period, and increase holding costs. Work with your broker to understand the progress payment schedule in advance and ensure the builder's payment milestones align with the lender's drawdown stages.

Fixed Price Building Contracts and Cost Blowouts

Lenders prefer fixed price building contracts because the total build cost is locked in before funding is approved. Under a fixed price contract, the builder agrees to complete the project for a specified amount, and any cost overruns are the builder's responsibility. That gives the lender certainty that the loan amount will cover the project, and it protects you from needing to find additional funds mid-build.

Cost plus contracts, where you pay the builder's costs plus a margin, create uncertainty. If material prices increase or the build takes longer than expected, the final cost could exceed the loan amount. Most lenders will not approve construction funding under a cost plus arrangement unless you can demonstrate substantial equity or cash reserves to cover potential overruns.

Before signing the building contract, confirm the structure is acceptable to your lender. If you are building custom townhouses with a smaller builder who prefers cost plus terms, discuss alternatives or find a lender who will accept that contract type with appropriate buffers built into the loan amount.

What Happens If You Cannot Settle the Land on Time

If your land purchase is conditional on finance and your construction loan approval does not come through before settlement, you risk defaulting on the land contract. The vendor may retain your deposit and pursue damages. Even if your construction funding is approved in principle, final approval usually depends on a satisfactory valuation, clear title, and no material changes to your financial position between application and settlement.

Extension clauses in the land contract can provide breathing room, but they are not automatic. Some vendors will agree to a 30 or 60-day extension if your finance is delayed. Others will not, particularly in a market where land values are rising and alternative buyers are available. Build contingency into your land contract that allows for realistic approval and settlement timelines, and keep your broker updated on any changes to your income, debts, or deposit source between application and settlement.

Renovation Finance as an Alternative to New Builds

If the townhouse project feels too complex or if council approval is uncertain, consider whether a large-scale renovation or subdivision of an existing property might achieve similar returns with fewer moving parts. Renovation finance follows a similar progressive drawdown structure but avoids the development application process for new builds. Some buyers find that purchasing a large block with an existing dwelling, subdividing, and renovating or extending both structures offers a faster path to dual income without the risks of ground-up construction.

That approach is not suitable for every site or every goal, but it is worth evaluating before committing to a full construction project. Your broker can help you model both scenarios and compare the funding requirements, timelines, and potential returns.
