A builder’s first progress invoice can arrive when your block still looks like a patch of dirt. That can feel confronting, particularly when the full home is months away from being finished. Construction loan payment stages are designed to match the release of your loan funds to visible progress on site, rather than handing over the entire loan amount at settlement.
For Australian borrowers, understanding this process before signing a building contract is one of the clearest ways to avoid cash-flow surprises. Your builder’s payment schedule, your lender’s drawdown requirements and your own contribution all need to work together. If one part falls out of step, construction can slow down while the issue is resolved.
How construction loans work differently
A standard home loan is usually advanced in one lump sum at settlement. A construction loan is different: the lender approves a total facility, then releases funds progressively as each agreed stage is completed. These releases are often called progress payments, drawdowns or construction advances.
During the build, interest is generally charged only on the amount drawn, not on the full approved loan limit. If $150,000 has been released from a $700,000 construction loan, interest is normally calculated on the $150,000 balance. This can make the early months more manageable, although the repayments rise as further funds are drawn.
Many construction loans are interest-only while the build is underway, then revert to principal and interest after completion. This is common, not automatic. The exact repayment structure, construction period and conditions depend on the lender and your loan contract.
It also matters whether you are buying land and building, or already own the land. When land is being purchased, the land component may settle first. The construction portion is then accessed through progress payments once the builder starts work.
The typical construction loan payment stages
The names and percentages of stages vary by building contract, state and lender. For a conventional residential build, however, the following sequence is common.
Deposit and pre-construction costs
Before work starts, you may need to pay a builder’s deposit, as well as costs for plans, engineering, soil tests, council or certifier approvals, site preparation and insurance. Lenders often expect the builder’s deposit to be paid from your savings rather than funded through the construction loan.
This point deserves attention because the deposit rules in residential building contracts can vary between states and territories. Do not assume a deposit is refundable or that your lender will reimburse it later. Confirm the amount, timing and funding source before you sign.
Base or slab stage
The base stage usually covers site works, excavation, plumbing below the slab, footings and the concrete slab or subfloor. Once these works are complete, the builder issues an invoice and requests payment.
Your lender may arrange a valuation or inspection to confirm the stage has been reached before releasing funds. A valuation is not a detailed building-quality inspection. It is primarily intended to establish that progress supports the amount being requested, so borrowers should not treat it as a substitute for their own independent inspection if they want one.
Frame stage
At frame stage, the structural frame is erected. For a brick veneer home, this normally includes the timber or steel frame, roof trusses and related structural elements. The building now starts to look recognisably like a house, but there is still substantial work ahead.
Frame invoices can be significant. Check that your approved loan amount, available contingency and expected timing still align before authorising a drawdown. This is a sensible point to raise any concerns about delays, variations or costs that have emerged since the contract was signed.
Lock-up stage
Lock-up generally means external walls, roofing, windows and external doors are in place, allowing the home to be secured. In some contracts, garage doors and certain external finishes are also included.
The exact definition matters more than the label. Read your contract’s stage description rather than relying on what you assume “lock-up” means. A builder can only claim a progress payment when the contractual requirements for that stage have been met.
Fixing or fit-out stage
This is when internal work becomes visible: plasterboard, cabinetry, internal doors, tiling, skirting, architraves, plumbing fixtures and electrical fittings may be installed. Depending on the contract, painting and some appliance installation may also sit within this stage.
Fixing is often the stage where variations become most apparent. A higher-grade tapware selection, extra power points, upgraded flooring or an altered kitchen layout may be reasonable choices, but they can require money outside the original loan budget. Keep every variation in writing and ask how it will be funded before approving it.
Completion or practical completion
The final payment is normally requested at practical completion. This generally means the home is complete enough to be occupied, subject to minor defects or outstanding items. Before authorising the final drawdown, conduct a thorough final inspection and prepare a defects list where appropriate.
Do not confuse practical completion with every detail being perfect. Small items may remain, but major incomplete work or defects should be addressed in line with your contract. You should also ensure required certificates, approvals and occupancy documentation are available before taking possession.
What happens when a progress payment is requested?
A typical process begins with the builder issuing an invoice after completing a stage. You review the claim, confirm the work aligns with the contract, and provide the lender with any required authority or documentation. The lender then assesses the request and may organise an inspection or valuation before paying the builder.
The money usually goes directly to the builder rather than through your personal bank account. Allow time for this process. If you wait until the invoice due date to submit documents, you may create unnecessary pressure for both yourself and the builder.
A practical approach is to ask your lender or broker at the outset how drawdowns are requested, what documents are needed and the usual processing timeframe. Keep copies of invoices, variation documents, building contract schedules and correspondence in one place. This reduces the risk of a missing document delaying payment.
Your contribution, contingency and valuation risk
Most lenders require your contribution to be used first. In simple terms, if you have a deposit or equity contribution, the lender may apply it to early costs and early construction stages before loan funds are released. This can surprise borrowers who expected to retain all their savings until later in the build.
A contingency allowance is also valuable, particularly for custom homes, sloping sites, regional builds or projects with complex site works. It is not a licence to expand the scope casually. It is a financial buffer for genuine changes or costs that arise during construction.
There is another issue to consider: the lender assesses the completed property value, not simply the total of your land and building contract costs. If valuations come in lower than expected, you may need to contribute more funds, revise the project or consider a different lending structure. This is why a realistic contract price and clear inclusions are so important from the beginning.
Common issues that disrupt payment stages
The most frequent problems are not usually caused by the concept of progress payments itself. They arise when expectations were unclear before construction commenced. Delays in approvals, wet weather, supply shortages, disputed workmanship, incomplete lender documents and unpriced variations can all affect the timing of a drawdown.
Be especially careful with provisional sums and allowances. These are estimates for items that may not be fully priced when the contract is signed. If the actual cost is higher, the difference may become your responsibility. Ask what has been allowed for, what could change, and whether the proposed loan includes sufficient breathing room.
If a builder requests payment before you believe the stage is complete, do not ignore the invoice, but do not approve it automatically either. Raise the concern promptly, refer to the contract and seek independent building or legal advice where needed. A finance adviser can help explain the loan and cash-flow implications, but building quality and contract disputes may require specialist advice.
Planning your construction loan payment stages with confidence
Before committing to a build, compare the payment schedule in the building contract with the lender’s construction schedule. They do not always use identical language or percentages, and differences should be resolved early. Check your expected interest-only repayments at several points in the build, not just at the first drawdown.
It is also wise to retain accessible funds for costs outside the loan, such as moving expenses, landscaping, window furnishings, utility connections or upgrades not included in the building contract. These expenses can be overlooked because they sit outside the headline build price.
At MAK Finance Experts, construction lending is approached as a coordinated funding plan, not simply a loan approval. The right structure depends on your land position, contract, income, available contribution and tolerance for cost changes.
Before you sign, take the time to map each expected payment against your available funds and the lender’s requirements. A well-planned build gives you more than a path to the keys – it gives you room to make decisions calmly when the project is underway.
