10 Steps to Prepare Your Construction Loan Application

Start With Council Approval in Hand

Your construction loan application needs a development application approved by your local council before most lenders will assess it. This approval confirms your build meets zoning requirements, setbacks, height restrictions, and any local planning overlays that apply to your block.

Consider a buyer who purchased land in Holland Park with plans for a two-storey custom design. The council required amendments to the roofline and side boundary setback before approval, which delayed their original timeline by six weeks. Because they worked through the development application before approaching lenders, they had certainty on what could actually be built and avoided submitting an application based on plans that would later change. Lenders assess construction loan applications against approved plans, so any variation after approval can mean resubmitting documents or reassessing loan amounts.

Council approval also triggers the clock on construction commencement clauses in some loan contracts. You may need to commence building within a set period from the Disclosure Date, typically six to twelve months depending on the lender. If you secure approval but then delay your loan application, you could be working within a tighter construction start window than expected.

Lock in a Fixed Price Building Contract

A fixed price building contract with a registered builder is non-negotiable for most construction to permanent loan products. The contract sets out the total build cost, inclusions, and progress payment schedule, which lenders use to structure your progressive drawdown and assess whether your loan amount covers the full project.

Fixed price contracts protect you from cost overruns during construction, but they also protect the lender. A cost plus contract, where you pay for materials and labour as they occur, introduces uncertainty that most mainstream lenders won't accept. If you're working with a custom design outside the project home loan structure, you'll still need a builder willing to commit to a fixed price rather than an estimate or provisional sum beyond minor variations.

The contract should break down progress payments into clear stages tied to construction milestones: base stage, frame stage, lock-up, fixing, and completion are the typical intervals. This schedule feeds directly into your construction draw schedule, which determines when funds release to your builder.

Confirm Your Land is Suitable for Finance

Not all land qualifies for a land and construction package, even if you already own it. Lenders assess land based on size, zoning, access to services, and whether it has title or is still under a land contract. If you're buying land and building simultaneously, the land component is usually financed first, with construction funding activated once settlement occurs and council plans are approved.

Blocks in bushfire-prone areas, flood zones, or with contamination issues can trigger additional requirements or limit which lenders will support your application. Some lenders also have minimum land size requirements, particularly for acreage or rural blocks where serviceability and resale become harder to assess. If your land has an easement, right of way, or other encumbrance, disclose it upfront. It may not prevent approval, but discovering it mid-application delays the process.

If you're buying a house and land package from a developer, confirm whether the land contract allows you to nominate your own lender or requires you to use the developer's preferred financier. Some contracts lock you into specific construction finance arrangements that may not suit your situation.

Understand the Progressive Drawing Fee

Most construction loan applications involve a Progressive Drawing Fee, which covers the lender's cost of inspecting the build at each payment stage and releasing funds to your builder. This fee typically ranges from $800 to $1,500 depending on the lender and the number of progress inspections required.

The fee is charged upfront or added to your loan amount at settlement. It's separate from your building contract and your settlement costs, so factor it into your total funding requirement. Some lenders cap the number of inspections included in the fee, so if your builder requests additional progress payments beyond the standard five or six stages, you may incur extra charges.

Progress inspections verify that the work claimed by your builder has actually been completed before the lender releases the next payment. The inspection is usually conducted by a third-party valuer or building inspector, not by the lender's staff. This protects both you and the lender from paying for incomplete work.

Prepare for Interest-Only Repayment Options During Construction

During the construction phase, you only charge interest on the amount drawn down, not the full loan amount. Because your builder receives funds progressively as each stage completes, your loan balance increases over time rather than starting at the total approved amount.

Most lenders offer interest-only repayment options during construction, which keeps your repayments lower while you're still paying rent or covering your existing housing costs. Once the build completes and you move into principal-and-interest repayments, your repayment amount will increase. If you're holding onto your current property during the build, you need to demonstrate you can service both loans simultaneously during construction and the full construction loan once it converts.

Some lenders calculate serviceability based on the full loan amount from day one, even though you won't draw it all immediately. Others assess it based on projected drawdowns, which can improve your borrowing capacity if you're building in stages or starting with land purchase before construction.

Get Your Documents in Order Early

Your construction loan application requires more documentation than a standard home loan. You'll need the usual income verification, asset and liability statements, and identification, but you'll also need your building contract, council-approved plans, engineer's report if required, and a breakdown of your progress payment schedule.

If you're using savings for your deposit, lenders want to see at least three months of account statements showing the funds sitting in your account, not transferred in recently from another source. If your deposit includes a gift or family contribution, you'll need a statutory declaration confirming it's not a loan that needs to be repaid.

Owner builder finance adds another layer. If you're acting as your own builder, you'll need to demonstrate relevant trade qualifications or construction experience, plus insurance and compliance with your state's owner-builder regulations. Queensland requires owner-builders to complete an approved course before starting work, and most lenders will ask for evidence of that completion before approving finance.

Budget for the Full Funding Requirement

Your loan amount needs to cover land purchase, construction costs, council and legal fees, the Progressive Drawing Fee, and any other costs incurred before your first drawdown. If you're buying land separately, you'll settle that first and then activate construction funding once your building contract and council approval are in place.

Consider a scenario where a buyer in Carina purchased land for one price and budgeted their build at another, but didn't account for a retaining wall required by the engineer's report. The wall added cost to the base stage, which pushed their total funding requirement beyond their original loan amount. Because they hadn't built that into their application, they either needed to increase their deposit or request a loan variation before construction could start. Planning for contingencies within your loan structure from the outset avoids that situation.

If you're including landscaping, fencing, or a driveway in your build, confirm whether those items are part of your fixed price building contract or additional costs you'll fund separately. Some lenders include them in the construction loan if they're part of the contract, others treat them as post-construction expenses.

Choose the Right Lender for Your Build Type

Not all lenders offer the same construction finance products, and some specialise in particular build types. A project home loan with a volume builder on a standard suburban block will have different lender options than a custom design on acreage or a house renovation loan on a character property.

If you're building a spec home or investment property, some lenders treat it differently to an owner-occupied build. Serviceability is assessed on projected rental income rather than your intention to live in it, and you may need a larger deposit. Off the plan finance for apartments or townhouses follows a different structure again, with settlement occurring at completion rather than progressively during construction.

Working with a mortgage broker who can access construction loan options from banks and lenders across Australia means you're not limited to one lender's appetite for your particular build. A broker can also structure your application to highlight the strengths of your position, whether that's strong serviceability, a low loan-to-value ratio, or a straightforward build with a reputable registered builder.

Understand How the Construction Draw Schedule Works

The construction draw schedule dictates when your builder gets paid and how your loan balance increases. Most schedules release funds at five or six intervals: base, frame, lock-up, fixing, and practical completion. The builder invoices you at each stage, you notify the lender, the lender arranges a progress inspection, and once the inspection confirms the stage is complete, the funds release.

Timing matters. If your builder completes the frame stage but the inspection is delayed, payment to your builder is delayed. If your builder has already paid sub-contractors for that stage, they're carrying the cost until the drawdown clears. Some builders build buffer time into their schedule to account for this, others expect payment within a set number of days and may slow progress if funds are held up.

You can't usually make additional payments or request funds outside the agreed schedule without lender approval. If you want to upgrade fixtures, add rooms, or make variations during the build, those changes need to be documented and approved by both your builder and your lender if they affect the loan amount or payment schedule.

Know What Happens After Practical Completion

Once your build reaches practical completion and you receive the keys, your construction loan converts to a standard home loan. Your interest rate may change if you were on a construction loan interest rate during the build, and your repayment structure shifts from interest-only to principal-and-interest unless you've arranged otherwise.

Some lenders require a final valuation at completion to confirm the property is worth at least the loan amount before converting the loan. If the valuation comes in lower than expected, you may need to adjust your loan structure or provide additional funds to meet the lender's loan-to-value ratio requirements.

If you used separate land and build loan facilities, they'll typically merge into one loan at completion. Your loan documentation at settlement will confirm how this works, but it's worth clarifying upfront so you know what your ongoing repayment and loan structure will look like once you move in.

Getting your construction loan application right from the start means fewer delays, fewer surprises, and a clearer path from council approval through to moving into your new home. Call one of our team or book an appointment at a time that works for you.
