Top tips to prepare for a construction loan

Getting Your Construction Loan Application Right Before You Submit

A construction loan application is approved or held up based on the quality of what you submit upfront. Lenders assess the builder, the contract, the costings, and council approval before releasing a single dollar, and missing documentation or unclear costings will delay settlement by weeks.

Killarney Vale sits close to both established suburbs and release areas heading toward Warnervale, which means we regularly see applications for knockdown rebuilds, dual occupancies on subdivided blocks, and house and land packages in nearby stages. Each project type requires slightly different preparation, but the same principle applies: lenders want to see a fixed price building contract, clear council approval, and a builder who meets their panel or accreditation requirements.

What Lenders Look for in a Construction Loan Application

Lenders assess three things before approving construction finance: your ability to service the loan, the suitability of the land, and the contract structure. Serviceability is calculated using the full loan amount, not just what you draw down during the build. That means if you are borrowing for both land and construction, the lender will assess you on the total combined debt from day one, even though you only pay interest on what has been drawn.

Consider a borrower purchasing suitable land for $450,000 with a build cost of $550,000. The lender assesses serviceability on the full $1,000,000, even though the land settles first and construction payments are released progressively. If income or existing debt limits borrowing capacity, the deal stalls before the contract is even assessed. Running the numbers early, before signing anything, is the only way to know whether the project is financeable.

Land suitability is checked through title, zoning, and DA approval. Lenders will not settle on land without clear council approval for the proposed build, and they will not fund a project where the land has easements, contamination, or title issues that affect construction. The contract must be a fixed price building contract with a registered builder. Cost plus contracts, where the final price is uncertain, are rarely accepted by mainstream lenders.

Choosing Between Land and Construction Packages or Buying Land Separately

If you are buying land and building separately, you will need to fund the land purchase first, then apply for construction funding once the build contract is ready. That creates a timing challenge because the land needs to settle before the build can start, but the construction loan will not be approved until council plans and a signed contract are in place.

In one scenario we see often, a buyer finds a block in a nearby estate, signs a land contract, then spends three months choosing a builder and finalising plans. By the time the DA is submitted, the land has already settled, which means the buyer has been paying interest on the land loan without progressing the build. Structuring the land purchase with a construction-ready approval in mind avoids that gap.

House and land packages streamline this process because the developer or builder has already secured DA approval for a set of home designs that suit the estate. You select the land and the design together, and the lender can assess both components in a single application. The trade-off is less flexibility in design, but the approval timeline is shorter and the contract is ready to go.

Fixed Price Contracts and Why Lenders Require Them

A fixed price building contract sets out the full cost of the build, the payment schedule, and the builder's obligations. Lenders use this contract to determine the loan amount and to structure the progressive drawdown. Without a fixed price, there is no cap on what the build might cost, and the lender has no certainty that the loan amount will cover completion.

The contract should include a clear progress payment schedule tied to construction stages: base, frame, lock-up, fixing, and completion. Each stage triggers a drawdown from the lender once a progress inspection confirms the work has been completed. If the contract lists vague milestones or bundles multiple stages together, the lender may reject it or request amendments before approval.

Most volume builders working in the Killarney Vale and Warnervale area use standard contracts that meet lender requirements. If you are working with a custom builder or a smaller operation, have the contract reviewed by your broker before signing. A contract that does not meet lender criteria will need to be renegotiated, which delays the application and can create tension with the builder.

Council Approval and Development Application Timing

Your construction loan will not settle until council approval is in place. For a standard single dwelling on a residential block, that usually means a Construction Certificate (CC) issued after DA approval. For a dual occupancy, subdivision, or modification to an existing structure, the DA process takes longer and may require additional reporting or neighbour consultation.

In Killarney Vale, where blocks vary in size and some properties sit on sloping or bushfire-prone land, the DA may include conditions around drainage, bushfire protection, or building height. Those conditions affect the build cost and the contract, so the DA should be lodged early and the contract adjusted once approval is confirmed. Signing a fixed price contract before DA approval can leave you locked into a price that does not account for required changes.

Lenders will accept a DA approval with conditions, provided the conditions do not prevent construction from commencing. If the DA requires further council sign-off or additional works before the CC is issued, the lender may delay the loan or request evidence that those conditions have been met.

How the Progressive Drawdown Works During Construction

Construction loans are drawn down in stages, and you only pay interest on the amount that has been released. After each stage is completed, the builder invoices the lender, a progress inspection is arranged, and the funds are released directly to the builder. Between drawdowns, you pay interest on the amount already drawn, which is lower than the full loan amount.

The progress payment schedule is set out in the building contract and should match the drawdown structure the lender will accept. Most lenders use a five-stage schedule, but some builders use six or seven stages, particularly for larger or custom builds. If the builder's schedule does not align with the lender's structure, the lender may hold payments or require the builder to consolidate stages.

You will also need to budget for a Progressive Drawing Fee, which is charged by the lender each time a drawdown is processed. This fee is separate from the loan establishment cost and typically applies to every stage after the first. It is worth confirming the fee amount before settlement, as it is not always disclosed upfront in loan summaries.

Preparing Your Documentation Before You Apply

Lenders require the building contract, council approval, soil test, insurance certificates, and builder accreditation before they will issue formal approval. Missing any of these documents will delay the assessment, and some cannot be obtained until certain steps are completed. For example, you cannot get a Construction Certificate until the DA is approved, and you cannot finalise a fixed price contract until the design is locked in.

Start by confirming the builder is either on the lender's approved panel or holds the necessary licences and insurance to meet lender criteria. Volume builders are usually pre-approved across most lenders, but if you are using a custom builder, check early. Some lenders will not fund builds with owner builder arrangements, and others require additional insurance or higher deposits.

Once the DA is approved and the contract is signed, gather the soil test, the engineer's report (if required), proof of builder insurance, and any specialist reports related to bushfire, flood, or contamination. These documents form part of the lender's valuation and risk assessment. If the valuer or credit team flags an issue with any of them, the loan may be declined or approved at a lower amount.

Timing Your Build Commencement to Meet Lender Conditions

Most construction loans include a condition requiring you to commence building within a set period from the loan settlement, typically six to twelve months. If the build does not start within that window, the lender may withdraw the facility or require you to reapply. That deadline is based on the assumption that council approval is current and the builder is ready to start.

Delays in appointing plumbers, electricians, or other sub-contractors can push out the start date, particularly in areas where trades are stretched across multiple developments. If you know the builder has a backlog or the site requires additional preparation, factor that into your timeline and confirm the lender's commencement condition will still be met.

If the build is delayed beyond the lender's deadline and the facility is withdrawn, you may need to reapply, which means updated income verification, a new valuation, and potentially a different interest rate if market conditions have changed. Keeping the builder and broker informed of any delays gives you time to request an extension before the condition lapses.
