Simple hacks to prepare your construction loan application

Construction finance works differently from standard home loans because funds are released progressively as your build reaches specific stages.

You're assessed on both your ability to service the full loan amount and your capacity to manage the build process itself. For someone coming out of a separation, this often means preparing a stronger application than you would for an established property purchase, particularly if your income has changed recently or you're building on land that forms part of a settlement.

Timing Your Application Around Settlement

Apply for construction finance after your financial separation is finalised, not before. Lenders assess your income and liabilities as they stand at application, and if you're still legally tied to a former partner's debts or awaiting a property settlement, your borrowing capacity will reflect that uncertainty.

Consider someone who owns suitable land after a property settlement and wants to build a new home. If they apply before their former partner's name is removed from a joint investment loan, the lender will count the full repayment as a liability, even if the separation agreement specifies the ex-partner is responsible for it. Waiting until refinancing or discharge is complete can increase borrowing capacity by several hundred thousand dollars. The same principle applies to child support arrangements. Once formalised through a binding agreement or court order, lenders assess the payment as either ongoing income or a fixed expense, which provides clarity and often improves serviceability compared to informal arrangements.

What Lenders Assess Before Approving a Build

Lenders require a fixed price building contract with a registered builder, detailed council plans showing development approval, and confirmation that your land title is unencumbered or that existing debts can be refinanced into the construction facility. They also check that you can commence building within a set period from the disclosure date, typically six to twelve months depending on the lender.

Your deposit must cover both the land value and a portion of the build cost. Most lenders require at least 10% of the total project value as genuine savings or equity, though some will accept a smaller deposit if you're an existing customer or meet specific criteria. If you're using equity from land you already own, the lender will order a valuation to confirm its current worth. That valuation needs to cover any existing debt on the land plus the portion of the build you're not borrowing.

For those building on land acquired during a separation, the deposit structure can look different. If you received the land as part of a property settlement and it's held in your name without a mortgage, that equity typically satisfies the deposit requirement. If there's still a loan against it, you'll need to show how much equity remains after accounting for that debt, and whether refinancing it into the construction facility makes sense. We regularly see clients who assume they need to sell the land and start again, when refinancing into a construction loan is often more direct.

The Progressive Drawing Fee and How It Affects Your Budget

Construction loans only charge interest on the amount drawn down at each stage, not the full approved amount. During the build, you'll make interest-only repayments on whatever has been released so far. Once construction is complete, the loan converts to a standard principal and interest or interest-only home loan, depending on what you've structured.

Most lenders charge a progressive drawing fee each time funds are released. This typically ranges from $300 to $500 per drawdown, with five or six drawdowns being standard across a build. That's an additional $1,500 to $3,000 in costs that sit outside your building contract and should be factored into your budget alongside council fees, insurance, and any variations.

If you're managing cashflow carefully after a separation, knowing these fees upfront prevents surprises. Some lenders waive the progressive drawing fee as part of a package or if you're borrowing above a certain threshold, so it's worth comparing.

Fixed Price Contracts and Cost Plus Structures

Most lenders will only approve construction finance against a fixed price building contract. This protects both you and the lender by capping the build cost and linking each progress payment to a defined stage of work. Owner builder finance is available, but fewer lenders offer it and those that do typically require a larger deposit and charge a higher interest rate.

A cost plus contract, where you pay the builder's costs plus a margin, creates uncertainty around the final loan amount. Unless you have significant cash reserves to cover potential overruns, a fixed price contract with a registered builder is the most reliable structure when your financial position is still stabilising after separation. The progress payment schedule is usually tied to stages like slab down, frame up, lockup, fixing, and practical completion. The lender arranges a progress inspection at each stage before releasing funds, which means your builder needs to meet the contractual milestones before they're paid.

Structuring Repayments During and After Construction

During the build, you'll make interest-only repayments on the drawn amount. If $150,000 has been released and the rate is 6.5%, you're paying around $810 per month in interest. Once the full loan amount is drawn and the build is complete, the loan converts and you can choose to continue with interest-only repayments or switch to principal and interest.

For someone rebuilding financial independence after a separation, interest-only repayment options during construction reduce the monthly commitment while you're potentially still covering rent or other housing costs. After completion, continuing with interest-only for a period can help with cashflow if you're managing other debts or saving for furniture and relocation costs. Alternatively, switching to principal and interest immediately starts reducing the loan balance, which may suit you if your income is stable and you want to build equity quickly.

The choice depends on your broader financial position. If you're consolidating other debts or managing a lower income than before, keeping repayments lower initially gives you breathing room. If you're looking to build wealth after separation and your income supports it, paying down the principal from the start reduces the total interest paid over time.

Land and Construction Packages Versus Buying Land Separately

A land and construction package involves purchasing land and contracting a builder as part of the same transaction, often through a developer's preferred builder. These packages can be convenient, but they're not always the most cost-effective option and they limit your choice of builder and design.

If you already own suitable land, building separately gives you more control. You can select your own builder, negotiate the contract directly, and tailor the design to your needs without being locked into a package deal. For someone starting fresh after a separation, that flexibility matters. You're not building a family home to someone else's specifications. You're building a home that reflects your next chapter, and being able to choose the layout, finishes, and budget without compromise is part of that process.

Preparing Your Application When Income Has Changed

If your income has dropped since separation, perhaps because you've reduced work hours or left a jointly run business, lenders will assess you on your current income and employment type. Stability matters more than volume. Someone earning $70,000 in a permanent role with three months of payslips will often have better serviceability than someone earning $90,000 through irregular contract work with no clear ongoing arrangement.

If you're self-employed, most lenders want two years of financials and a current Notice of Assessment from the ATO. If you've only been self-employed for twelve months, some lenders will consider one year of financials combined with evidence of ongoing contracts or clients, though the interest rate may be slightly higher. For those who have recently changed employment as part of a separation, such as leaving a business you ran with your ex-partner, waiting until you have at least three months in a new role before applying usually results in a smoother approval process. The same applies if you're receiving spousal maintenance or child support. Once formalised through a binding financial agreement or court order, most lenders will accept it as income, provided there's at least three months of consistent payments and the arrangement has several years remaining.

How Development Approval Timing Affects Your Finance

Your lender will require council approval before they'll issue a formal loan offer. If you've submitted a development application but haven't received approval yet, you can often get conditional approval from a lender based on the plans, but the finance won't be finalised until council signs off.

Council approval timeframes vary, but six to twelve weeks is common for a straightforward residential build. If your development application involves variations or is in an area with specific planning overlays, it can take longer. For someone working within a settlement deadline, such as needing to vacate a former shared property by a certain date, building in that approval time is important. Applying for finance before council approval is confirmed can leave you with a conditional offer that expires before you're ready to draw funds.

If you're renovating an existing property rather than building new, the approval process can be different depending on the scope of work. Minor renovations usually don't require a construction loan, and you might be able to access funds through a standard home loan refinance or a separate renovation facility. Major structural work involving plumbers, electricians, and multiple stages of progress payments will usually require a construction facility with progressive drawdowns.

Choosing Between Fixed and Variable Interest Rates

During the construction phase, most lenders charge a variable rate because the loan amount is changing each time funds are drawn. Once the build is complete and the loan converts, you can choose to fix part or all of the loan if rate certainty suits your circumstances.

For someone managing a tight budget after separation, fixing the rate locks in your repayment amount, which makes planning simpler. The trade-off is less flexibility. If you want to make additional payments to reduce the loan faster, most fixed rate products limit how much extra you can pay each year without incurring a fee. A variable rate allows unlimited additional payments and gives you access to any rate drops, but your repayments can increase if rates rise.

Splitting the loan between fixed and variable can give you some certainty while retaining flexibility. If your income is stable but you want the option to make extra repayments when possible, fixing 60% and keeping 40% variable is a common structure. The right mix depends on your risk tolerance and whether you're prioritising predictable repayments or the ability to pay down debt quickly.
