Avoid These 5 Construction Loan Documentation Mistakes

The contract arrives, council approval lands, and the builder's ready to start in six weeks.

Then your lender asks for a cost plus breakdown you don't have, a development application you thought wasn't needed, and a fixed price building contract that doesn't match the one you signed. Three weeks disappear while you scramble to resubmit, and your builder moves to the next job.

Construction loan applications fail more often on documentation than on serviceability. The approval process involves multiple parties, staged funding, and a level of detail most purchase loans never require. What you submit in the first round determines whether you settle on time or spend months chasing missing signatures and council stamps.

Submitting a Cost Plus Contract Without a Detailed Breakdown

Lenders funding construction prefer fixed price building contracts because the risk is capped. A cost plus contract shifts that risk to you, and most lenders either decline them outright or ask for enough supporting detail that the application stalls.

If you're building a custom design in Hawthorn East and your architect has recommended a cost plus arrangement, your lender will want a line-by-line estimate covering materials, labour, and margins. That estimate needs to be prepared by a registered builder and include allowances for every stage of the build. Without it, the valuer can't assess whether the land and construction package represents acceptable security, and the application sits incomplete.

In our experience, applicants who engage the builder early and request a formal estimate before lodging the loan application move through assessment in half the time. That upfront cost pays for itself in certainty.

Missing Council Approval or Development Application Documents

Your lender won't release the first drawdown until they've sighted council plans and confirmation that all planning permits are in place. If your project required a development application and you submit the construction loan application before council approval is finalised, you've created a timing problem that can't be solved by calling your broker twice a day.

Hawthorn East sits within Boroondara, where heritage overlays and neighbourhood character provisions mean even a relatively modest new build can require a full planning permit rather than a standard building permit. Assuming your project only needs a building permit when it actually required a development application is one of the more common documentation errors we see, and it typically adds eight to twelve weeks to your timeline.

Before lodging your construction loan application, confirm with your builder or architect exactly what council approvals apply to your site. If a planning permit is required, wait until it's been issued and all objection periods have closed. Your lender needs to see the stamped approval, not just evidence that it's been submitted.

Providing a Progress Payment Schedule That Doesn't Match Lender Draw Stages

Construction funding is released in instalments as the build progresses, and the lender's draw schedule rarely matches the payment schedule in your building contract. Your builder might expect five payments at specific milestones. Your lender might offer six draws tied to different stages. If those two schedules don't align, someone ends up waiting for money, and it's usually the builder.

Consider a scenario where your fixed price building contract includes a progress payment at frame stage, but your lender's progressive drawdown schedule splits that stage into base and frame as two separate inspections. The builder completes framing and invoices you. The lender conducts a progress inspection and confirms the base is complete but the frame isn't finished, so they release funds for the base only. You're now covering the gap between what the builder invoiced and what the lender released, often from your own savings.

The solution is to request your lender's draw schedule before signing the building contract, then ask your builder to align their progress payments with those stages. Most registered builders will adjust the payment structure if asked early enough. Trying to reconcile the two schedules after contracts are signed creates confusion, delays, and cashflow gaps that could have been avoided with a single conversation.

Forgetting to Include Costs Outside the Building Contract

The loan amount you apply for needs to cover more than the contract price. Lenders funding a land and build loan expect you to account for every cost between settlement on the land and completion of the build, including items your builder isn't responsible for.

That includes the Progressive Drawing Fee your lender charges each time they release funds, which can range from $300 to $500 per drawdown. It includes the cost of connecting services like water, gas, and electricity, which your builder may or may not include in the contract. It includes landscaping, driveways, and fencing if those items sit outside the scope of works. And it includes the progress inspection fees some lenders charge to assess whether each stage has been completed before releasing the next payment.

If you apply for a construction loan that only covers the land price and the building contract, you'll either need to find several thousand dollars during the build or apply for a loan variation midway through, which delays the next drawdown and frustrates everyone involved. Budget for the full project cost upfront, and include a contingency for variations, because most builds involve at least one.

Not Confirming the Builder's Licence and Insurance Before Lodging

Your lender will ask for proof that your builder holds current registration and adequate insurance before they'll assess the application. If your builder's licence has lapsed, or if their insurance doesn't meet the lender's minimum requirements, the application stops until those documents are updated.

In Victoria, that means sighting the builder's registration with the Victorian Building Authority and confirming they hold domestic building insurance that covers the full contract value. Some applicants assume the builder has this sorted and submit the loan application without checking. Then the lender requests the documents, the builder takes a week to respond, and the application timeline blows out.

Before you lodge, ask your builder for a copy of their current registration certificate and proof of insurance. Check the expiry dates, confirm the contract value is covered, and include those documents with your initial submission. It takes ten minutes and removes one of the more predictable approval delays.

Construction finance involves more documentation than most other loan types, but the requirements aren't arbitrary. Each document protects either you or the lender from a risk that's specific to staged funding. The faster you can provide what's needed, the sooner construction can commence.
