Beginner's Guide to Construction Loan Approval

What Lenders Assess for Construction Loan Approval

Lenders assess your income, deposit, the builder's credentials, and the construction contract when reviewing a construction loan application. Unlike a standard home loan where the security already exists, construction finance is advanced progressively as the build reaches certain stages, which introduces additional risk that lenders manage through stricter approval criteria.

Your borrowing capacity is calculated based on your ability to service the full loan amount, even though you will only draw down funds progressively during construction. Lenders apply the same serviceability tests used for established property purchases, which means your income needs to support the total loan value from day one. They also review the fixed price building contract to confirm the scope of works, the builder's licensing, and whether the contract includes a clear progress payment schedule tied to construction milestones.

The registered builder you select carries significant weight in the approval process. Lenders maintain lists of preferred builders and will conduct additional due diligence if your builder is not on that list. They want confirmation that the builder holds current insurance, has a history of completing projects on time, and operates under a fixed price contract rather than a cost plus arrangement. A cost plus contract, where the final price is not locked in, is rarely accepted by mainstream lenders because it introduces uncertainty around the final loan amount.

Deposit Requirements and Genuine Savings

You will generally need a deposit of at least 10% of the total land and construction cost, though 20% is preferred to avoid lenders mortgage insurance. The deposit must include genuine savings, which lenders define as funds held in your account for at least three months, demonstrating a pattern of disciplined saving rather than a one-off gift or loan from family.

For a land and construction package in Everton Park, where land prices vary depending on proximity to Mitchelton Station and local schools, the deposit is calculated on the combined value of the land and the completed home. If you already own the land, lenders will use a current valuation to determine equity, which can then contribute toward your deposit for the construction component.

Some lenders will accept equity in an existing property as your deposit, which can be useful if you plan to sell your current home once the new build is complete. This approach requires careful timing and a clear exit strategy, as you will be servicing both your existing mortgage and the construction loan interest during the build period.

The Fixed Price Building Contract Requirement

Lenders require a fixed price building contract signed with a registered builder before they will issue formal approval. This contract must detail the full scope of works, include a progress payment schedule aligned with construction stages, and specify a completion timeframe. Without this contract, a lender may provide conditional approval, but funds will not be available until the contract is finalised and reviewed.

The progress payment schedule typically includes five or six drawdowns tied to specific milestones such as base stage, frame stage, lockup, fixing, and completion. Each drawdown is released only after a progress inspection confirms the stage has been reached to a satisfactory standard. Lenders engage independent inspectors for this purpose, and you will pay a progressive drawing fee, usually between $300 and $500 per inspection, as part of the loan terms.

If you are building a custom design rather than selecting from a project home range, expect additional scrutiny during the approval process. Lenders want to see detailed architectural plans, a development application approved by Brisbane City Council, and confirmation that the design meets all relevant building codes. Custom builds often take longer to assess because the lender's valuer must determine the completed value based on plans rather than comparable sales data for a standard design.

Interest Charges During Construction

During the construction period, you will only be charged interest on the amount drawn down at each stage, not the full loan amount. Repayments during this period are typically interest-only, which keeps your monthly commitment lower while the build is progressing. Once construction is complete and the property is valued, the loan converts to a standard home loan with principal and interest repayments, unless you have negotiated a longer interest-only period.

Consider a scenario where you are building in Everton Park with a total construction cost of $400,000. At the base stage, the builder may draw down $50,000, so your interest charges are calculated only on that amount. As each subsequent stage is completed and additional funds are released, your interest charges increase incrementally. This structure reduces the cost of holding the loan during construction compared to borrowing the full amount upfront.

Some lenders offer a construction to permanent loan, which means you only go through one application and settlement process for both the construction phase and the ongoing mortgage. This can reduce legal costs and administrative steps, though not all lenders structure their products this way. It is worth comparing options to understand whether a single settlement or two separate loans will suit your circumstances.

Owner Builder Finance and Renovation Projects

If you plan to act as an owner builder, expect approval to be significantly more difficult. Most mainstream lenders will not provide finance for owner builder projects because the risk of cost overruns and delays is higher without a licensed builder managing the works. Specialist lenders do offer owner builder finance, but the loan-to-value ratio is typically capped at 60% to 70%, requiring a much larger deposit.

For renovation projects or knock-down rebuilds in established parts of Everton Park, such as near Stafford Road or around the heritage-listed areas, lenders assess the project as construction finance rather than a standard home improvement loan. You will need detailed plans, council approval, and quotes from licensed tradespeople covering the full scope of works. The lender will advance funds progressively based on a progress payment schedule, similar to a new build, and may require higher scrutiny if the existing structure is being retained and modified.

Timeline and Settlement Process

Once your construction loan is approved, you must commence building within a set period from the disclosure date, usually six to twelve months. If construction does not begin within this window, the approval may lapse and you will need to reapply. Lenders impose this condition because property values and your financial circumstances can change, affecting the risk profile of the loan.

Settlement occurs in two stages. The first settlement is on the land, where you take ownership and the lender advances funds to cover the land purchase. The second settlement, or final drawdown, occurs when construction is complete, the property is valued at its finished state, and the loan converts to a standard mortgage. During the period between these two settlements, you will be making interest-only payments on the progressive drawdowns.

For clients in Everton Park planning to build while living in their current home, timing is a common challenge. Construction timelines can extend due to weather, material delays, or changes to council plans, so building in a buffer before listing your existing property for sale can prevent financial pressure from holding two mortgages longer than anticipated.

Preparing Your Application

Strong preparation improves the likelihood of approval and shortens the assessment period. Gather your last two years of tax returns if you are self-employed, or recent payslips and employment contracts if you are a wage earner. Lenders will also request bank statements covering the last three to six months to verify your deposit, assess your spending patterns, and confirm you have sufficient funds to cover settlement costs in addition to your deposit.

If you are purchasing land and building as a package, ensure the land has suitable access to services such as water, sewerage, and electricity. Lenders will not approve construction finance on land that cannot be connected to essential infrastructure, and the cost of connecting services can add significantly to your project budget if not factored in from the start.

Your construction loan application should include a clear breakdown of costs, including the land price, construction contract value, professional fees for architects or engineers if applicable, and an allowance for landscaping or fencing if these are not included in the building contract. Lenders prefer to see a realistic budget with contingency built in, rather than a tight estimate that leaves no room for variation.

Call to Action

Construction finance involves more moving parts than a standard purchase, and having a broker who understands the process can make a material difference to the outcome. Call one of our team or book an appointment at a time that works for you.
