10 Ways Construction Loans Work for House & Land Packages

Construction Loans Fund Your Purchase in Stages, Not Upfront

A construction loan pays your builder at set stages as work completes, not as a single lump sum at settlement. You'll typically receive funds across four to six progress payments, with each release triggered by an inspection confirming the stage is complete. Between drawdowns, you'll only pay interest on the amount released so far, which keeps early costs lower than a standard mortgage during the build phase.

Consider a family lawyer purchasing a house and land package in a growth corridor. The land component settles first, with the full land price funded at that point. Once the slab is poured, the first progress payment releases to the builder. Frame completion triggers the second drawdown. Lock-up, fixing, and practical completion each trigger subsequent payments. By practical completion, the full loan amount has been drawn, and the loan converts to principal and interest repayments unless you've structured it differently.

The structure matters because it directly affects your cash position during the build. If you're managing school fees, vehicle loans, or other commitments while building, the lower interest costs during construction provide breathing room that wouldn't exist with a traditional mortgage.

Fixed Price Building Contracts Anchor Your Loan Amount

Lenders require a fixed price building contract before approving construction finance. This contract locks in the total build cost, which allows the lender to assess the completed property value against the final loan amount. Without a fixed price, the lender has no certainty that the project will stay within the approved loan amount, and most won't proceed on a cost plus contract for owner-occupier house and land packages.

Your builder provides the fixed price contract after finalising plans and selections. The contract will specify the base price, any upgrades or variations you've chosen, and the payment schedule tied to construction stages. Once signed, that figure becomes the basis for your loan application alongside the land price. The lender will also require council approval for the build, confirming the design meets planning requirements and can legally proceed on that block.

In our experience, family lawyers often underestimate the time required between land settlement and the start of construction. If your contract requires you to commence building within a set period from the disclosure date, factor that timeline into your settlement planning. Delays in finalising plans or obtaining council approval can compress your buffer.

Progressive Drawing Fees Apply to Each Release of Funds

Most lenders charge a progressive drawing fee each time they release funds to your builder. This fee typically ranges from $200 to $400 per drawdown and covers the cost of arranging an inspection and processing the payment. Over five or six progress payments, these fees add up to $1,000 to $2,400, which you'll need to budget for separately from your deposit and settlement costs.

Some lenders bundle the fee into the loan amount, while others require you to pay it upfront before releasing each drawdown. If you're funding the build while also covering rent or an existing mortgage, confirm how your lender structures these fees so you're not caught short at drawdown.

The fee structure varies between lenders, and it's one of several cost differences that affect the true cost of construction finance. When comparing construction loan options, the headline rate alone won't tell you which structure works for your cash flow.

Land Settlement Happens Before Building Starts

You'll settle on the land component before construction begins, which means you'll start paying interest on the land portion immediately, even though the house won't be habitable for months. This creates a dual cost scenario where you're servicing the land loan while also covering your current accommodation, whether that's rent or an existing mortgage.

Some lenders offer interest capitalisation during the construction period, where the interest accrues and is added to the loan balance rather than paid monthly. This reduces your out-of-pocket costs during the build but increases the final loan balance and the interest you'll pay over the life of the loan. Other lenders require interest-only repayments from land settlement onward, which keeps the balance steady but requires monthly payments throughout construction.

As an example, if you're purchasing land for $350,000 and building a home for $550,000, you'll be servicing interest on $350,000 from land settlement, then progressively more as each building drawdown occurs. By the time the frame is up, you might be paying interest on $600,000 while still renting elsewhere. The total monthly cost during construction can exceed what your final mortgage repayments will be, which surprises many borrowers who assume costs will be lower while the build is underway.

Lenders Assess Serviceability on the Full Loan Amount

Even though you'll only draw funds progressively, lenders assess your application based on your ability to service the full loan amount from day one. They'll calculate repayments as if the entire loan is drawn, then apply their serviceability buffer to ensure you can manage repayments even if rates rise. This means your borrowing capacity for a construction loan is the same as it would be for an established property at the same price.

For family lawyers with variable income due to performance bonuses, profit share, or recent partnership transitions, this assessment can be more restrictive than expected. Lenders typically average your income over two financial years, and they'll exclude or heavily discount income sources they consider non-ongoing. If you've recently moved firms or stepped into a new role, the timing of your application relative to your income documentation can shape the outcome.

The assessment also accounts for your existing commitments, including any mortgage, car loans, or credit card limits. If you're holding onto an existing property and plan to sell after moving into the new build, some lenders will exclude your current mortgage from serviceability once contracts exchange, while others won't adjust their assessment until settlement. That difference can determine whether your application proceeds or stalls.

Progress Inspections Trigger Each Drawdown

Before releasing funds to your builder, the lender arranges an inspection to confirm the claimed stage is complete and the work meets acceptable standards. The inspector checks that the slab is poured and cured, the frame is complete and braced, or the roof is on and the building is locked up, depending on which payment is being claimed.

If the inspector identifies incomplete work or quality concerns, the lender may withhold part of the drawdown until the builder rectifies the issues. This protects you from paying for work that hasn't been completed, but it can also delay your builder's cash flow and create tension if the builder disputes the inspector's findings.

In a scenario where your builder claims the lock-up stage is complete but the inspector notes missing window installations or incomplete brickwork, the lender might release 80% of the scheduled drawdown and hold the remaining 20% until the defects are resolved. Your builder will push for full release, but the lender's obligation is to ensure funds match the actual progress, not the claimed progress.

The Loan Converts to Standard Principal and Interest Terms at Completion

Once the build reaches practical completion and you've received the occupancy certificate, the construction loan converts to a standard mortgage. At this point, you'll begin making principal and interest repayments based on the full loan amount unless you've arranged for an interest-only period to continue.

The conversion happens automatically in most cases, with the lender adjusting your repayment schedule to reflect the new loan structure. If you've been capitalising interest during construction, your loan balance at conversion will be higher than the original approval amount, and your repayments will reflect that increased balance.

Some borrowers arrange to refinance at completion rather than converting the construction loan, particularly if they can access a lower rate or more suitable loan features elsewhere. If you're considering this approach, factor in the timing required to arrange a new loan and settle before your construction loan converts. Refinancing during or immediately after construction is more complex than refinancing an established property, because valuations are less certain and some lenders won't accept a newly completed build until it has been occupied for three to six months.

Development Application Delays Affect Your Start Date and Holding Costs

If your house and land package requires a development application rather than a standard building permit, the approval timeline can extend by several months. This delay pushes out your construction start date, which extends the period you're paying interest on the land without the house being built.

Development applications typically apply when the design doesn't meet standard planning provisions, when the block has specific overlays or covenants, or when the estate has design guidelines that require council assessment. Your builder or the land developer should clarify upfront whether a development application is required, but it's worth confirming independently because the distinction shapes your timeline and holding costs.

If you've settled on the land expecting to start construction within 60 days but the development application takes four months to approve, you'll be paying an additional three months of interest on the land loan before the first building drawdown occurs. At current variable rates, that could add several thousand dollars to your total costs, and it extends the period you're funding both the land and your existing accommodation.

Not All Lenders Offer Construction Finance for House and Land Packages

Construction finance sits outside the standard lending policies of some banks, particularly for borrowers with lower deposits or complex income structures. Even if you qualify for a standard home loan with a particular lender, they may not extend that approval to construction finance due to the additional risk and administrative complexity involved in progressive drawdowns and inspections.

This limitation matters for family lawyers seeking to use LMI waivers, because not all lenders who offer professional waivers also provide construction loans. If you're planning to build with less than a 20% deposit and want to avoid lenders mortgage insurance, your options narrow to the handful of lenders who offer both construction finance and professional LMI waivers for legal practitioners.

The reduced lender panel also affects pricing, because fewer options means less competitive tension on rates and fees. You may find the rate offered on a construction loan sits 0.10% to 0.30% higher than the equivalent rate on an established property loan, even with the same lender. That margin reflects the lender's additional risk and administrative cost, but it also reflects the reduced competition in the construction lending space.

Your Builder's Registration and Financial Stability Affect Lender Approval

Lenders require your builder to hold current registration in the state where you're building, and they may also conduct a financial stability check to confirm the builder is solvent and able to complete the project. If your builder has recently entered administration, has outstanding legal claims, or shows signs of financial stress, the lender may decline your application even if you meet all other criteria.

This requirement protects the lender's security, because an incomplete build leaves them with a part-finished property that's worth less than the amount they've advanced. For you, it provides some assurance that the builder you've contracted with has been vetted by a third party, though it's not a guarantee they'll complete the work on time or to the quality you expect.

If you're purchasing a house and land package through a volume builder operating in a new estate, most lenders will have that builder on their approved list and the check will be routine. If you're using a smaller or less established builder, be prepared for the lender to request additional documentation, including financial statements, evidence of insurance, and details of other projects underway. In some cases, the lender may decline to proceed if they're not satisfied with the builder's financial position, which can derail your purchase if you've already exchanged contracts.

Once construction completes and the loan converts, your cash flow stabilises and you're no longer managing the dual cost of servicing the loan and covering separate accommodation. If you're planning to build while managing other financial commitments, the structure and timing of your construction loan will shape your cash position for the next 12 to 18 months.
