You have received home loan pre-approval and found a builder—but does that mean construction can start? Usually, not yet. Pre-approval confirms that a lender may be prepared to lend up to a certain amount based on the information assessed at that time. Before the builder can begin, you will generally still need suitable land and building contracts, final loan approval, valuations, building approvals, insurance and any lender conditions to be satisfied.
This guide explains what normally happens after pre-approval, how progress payments affect your budget and what can influence the construction timeline. It draws on our experience helping a young engineer and nurse prepare to build their first home in Brisbane. They had received a pre-approval within 24 hours, but were still asking the most important question: “What do we do next?”
To protect our clients’ privacy, identifying details have been limited. This article is general information only. Requirements, timeframes, lending criteria and outcomes vary.
Can you start building as soon as you receive pre-approval?
Pre-approval is an important milestone, but it is not normally authority to commence construction. It is often conditional and time-limited. The lender still needs to assess the actual property, building contract, valuation and updated financial position before granting final approval.
Construction can generally begin only after the finance and building requirements are ready. Depending on your situation, this may include:
- settlement of the land or confirmation of how the land purchase will be funded;
- a signed fixed-price building contract, plans and specifications;
- a lender valuation based on the proposed completed home;
- formal or unconditional loan approval;
- council, planning or building approvals where required;
- builder’s insurance and any documents required by the lender; and
- a confirmed site-start date from the builder.
The exact order can change depending on whether you already own the land, are buying a house-and-land package or are arranging separate land and construction contracts.
Step 1: Recheck your pre-approval and total budget
Start by checking the expiry date and conditions of your pre-approval. If your income, expenses, debts, deposit, interest rates or lender policy have changed, the borrowing position may also change. Avoid treating the maximum pre-approved amount as the amount you should automatically spend.
Your working budget should cover more than the land price and builder’s headline quote. Before signing contracts, confirm how much of your own funds may be needed and keep an appropriate contingency. First home buyers can also review the broader process of financing a new home purchase before committing to a property or build.
Step 2: Review the land and building contracts
The lender usually needs the signed land contract, building contract, plans, specifications and progress-payment schedule before completing its assessment. The building contract should clearly state the construction price, inclusions, exclusions, payment stages and expected construction period.
Look beyond the base price. Depending on the contract, extra costs may include:
- site works, soil tests and engineering requirements;
- design upgrades, variations and provisional allowances;
- driveways, fencing and landscaping;
- window coverings, selected appliances and finishing items;
- utility connections, approvals and council-related charges; and
- rent or temporary accommodation if completion is delayed.
Consider obtaining independent legal and building advice before committing. A lender’s approval does not replace your own review of the contract.
Step 3: Move from pre-approval to final loan approval
Once the contracts and plans are available, the lender can assess the actual proposal. It may order an “as if complete” valuation, which estimates the value of the property after the approved construction is finished. The lender will also confirm whether the contract, builder, loan amount and your current financial circumstances meet its policy.
If the valuation is lower than the total land and construction cost, or if the project includes items the lender will not fund, you may need to contribute more money. This is one reason to avoid using every dollar of savings for the initial deposit.
Step 4: Satisfy the conditions required before construction
Formal approval may still include conditions that must be completed before the first construction payment. These can vary, but commonly relate to signed loan documents, evidence of your contribution, council-approved plans, builder’s insurance, land settlement and confirmation that construction can lawfully commence.
Your builder will also have its own pre-site process. Colour selections, engineering, permits, site preparation and scheduling can affect the start date. Loan approval and builder readiness therefore need to come together before work begins.
Step 5: Understand how progress payments work
A standard home loan is commonly advanced at settlement in one main payment. A construction loan is usually released progressively as the builder completes agreed stages. Typical stages include deposit, base or slab, frame, lock-up, fixing and completion, although the names and percentages vary by contract and lender.
At each stage, the builder sends a progress claim. Before releasing funds, the lender may request the invoice and may arrange an inspection or valuation. Check early that the builder’s payment schedule aligns with the lender’s requirements. A mismatch may delay payment or require you to contribute funds.
Step 6: Plan for rent and increasing repayments during the build
During construction, interest is commonly calculated on the amount already drawn rather than the full approved construction limit. Repayments may start relatively low, then increase as more progress payments are released and the loan balance rises.
If you are renting, include both rent and estimated construction-loan interest in your cash-flow plan. Also allow for normal living expenses, contract variations and possible delays. A mortgage repayment calculator can help you test different loan amounts and rates, but a construction loan needs a staged estimate because the balance changes over time.
In our clients’ situation, mapping the expected drawdowns alongside their rent transformed a confusing loan concept into a household budget they could understand. The figures were indicative rather than guaranteed, but the exercise showed where additional buffer might be needed.
Step 7: Allow for a realistic construction timeline
The contract may include an estimated construction period, but the total journey is longer than the physical build. Finance assessment, valuations, land registration or settlement, permits, builder pre-site work and final scheduling can all occur before the first day on site.
Weather, material availability, labour, variations and inspections may then affect completion. Avoid planning your rental exit or moving date around the earliest possible handover date. A contingency for additional rent and interest can provide valuable flexibility. Use our savings calculator to turn a target buffer into a regular savings plan.
What should you compare when choosing a construction lender?
The interest rate matters, but it is only one part of the decision. Construction borrowers should also compare:
- progress-payment and inspection procedures;
- valuation requirements and drawdown fees;
- how and when the borrower’s own funds must be used;
- treatment of variations and cost overruns;
- offset, redraw and repayment features; and
- the support available while the build is underway.
The cheapest-looking loan may not be the most suitable if its process does not align with your contract, builder or cash flow.
Your next-step checklist after pre-approval
- Confirm the pre-approval expiry date, conditions and realistic spending limit.
- Prepare a total budget that includes costs outside the building quote.
- Review the land and fixed-price building contracts before signing.
- Provide the contracts, plans and specifications for lender assessment and valuation.
- Obtain final approval and complete all finance and building conditions.
- Confirm how progress claims, rent and repayments will affect cash flow.
- Keep a contingency for delays, variations and completion costs.
From uncertainty to a clear plan
The young couple in this story already had a fast bank pre-approval. They chose to proceed with us because they wanted more than an approval letter: they wanted to understand the road ahead.
After working through the contracts, progress payments, expected repayments, rent and potential additional costs, they had a much clearer view of what needed to happen before construction and how to prepare for each stage. The value was not simply finding a loan; it was giving them the information and ongoing support to make decisions with confidence.
