Construction Loan Approval Works Differently
Construction loan approval involves more than proving you can service a standard home loan. Lenders assess the viability of your building project, the credentials of your registered builder, and your ability to manage progress payments over months of construction. Teachers applying for construction finance often underestimate how much detail lenders require before releasing funds.
Consider a teacher applying for a land and construction package in regional Victoria. The application includes the purchase price for the block, a fixed price building contract, and evidence of council approval. The lender wants to see that the build can be completed within the contract timeline, that the registered builder holds current insurance, and that the borrower can cover both construction interest and their current rent during the build. If any element is unclear or incomplete, the application stalls.
Lenders Check Your Builder First
Your builder's credentials matter as much as your own financial position. Lenders verify that your registered builder holds a current licence, adequate insurance, and a track record of completing projects on time. They will not approve construction funding if the builder cannot demonstrate financial stability or has a history of incomplete work.
A lender reviewing a custom home finance application will check whether the builder is registered in the relevant state, holds Home Warranty Insurance, and has completed similar projects in the past 12 months. If your builder is newly registered or operating under a cost plus contract without a fixed price, expect additional scrutiny. Some lenders will decline owner builder finance altogether unless you can prove relevant trade qualifications and experience.
The Fixed Price Building Contract Is Non-Negotiable
Most lenders will only approve construction loans against a fixed price building contract. This contract locks in the total build cost, protects you from budget blowouts, and gives the lender certainty that the project will not exceed the approved loan amount. Without it, your application will not proceed.
In our experience, teachers who start the approval process before finalising their building contract face delays. The lender needs to see the full contract, including the scope of work, the progress payment schedule, and any allowances for fixtures or finishes. If the contract includes provisional sums or cost plus elements, the lender may reduce the loan amount or request additional equity to cover potential overruns.

Council Approval and Development Application Timing
You cannot draw down construction funds until council approval is in place. Lenders require evidence that your development application has been approved and that all conditions have been met before the first progress payment is released. If you apply for finance before securing council plans, the approval will be conditional and the loan cannot settle until the plans are finalised.
A teacher building in a growth corridor submitted a construction loan application with a building contract and land title, but without final council approval. The lender issued conditional approval, but the loan could not settle for another six weeks while the builder resolved drainage conditions with the local council. The delay pushed back the build start date and extended the period during which the borrower paid both rent and interest on the land.
Lenders Only Charge Interest on the Amount Drawn Down
During construction, you do not pay interest on the full loan amount. Lenders only charge interest on the funds that have been drawn down at each stage of the build. This is known as progressive drawdown, and it reduces your repayment burden while the property is incomplete.
When you submit a construction loan application, the lender sets out a progress payment schedule based on the building contract. At each stage, the builder requests a draw, the lender arranges a progress inspection, and funds are released once the work is verified. Your repayments increase gradually as more money is drawn. Most lenders offer interest-only repayment options during the construction phase, converting to principal and interest once the build is finished and you move in.
The Construction Draw Schedule Needs to Match Your Contract
Your lender's progress payment schedule must align with the stages outlined in your fixed price building contract. If there is a mismatch between when the builder expects payment and when the lender releases funds, the build can stall.
A typical progress payment schedule includes a deposit, base stage, frame stage, lock-up, fixing, and practical completion. Some builders structure payments differently. Before lodging your construction loan application, compare the builder's payment terms with the lender's progressive drawing process. If the builder requires a larger deposit than the lender will release upfront, you may need to cover the shortfall from your own savings.
Borrowing Capacity Includes Construction Interest and Living Costs
Lenders calculate your borrowing capacity by factoring in the interest you will pay during construction, plus your ongoing rent or mortgage. If you cannot service both, the loan will not be approved.
A teacher earning $95,000 per year applies for construction funding to build a new home while renting. The lender calculates repayments based on the full loan amount, even though interest during construction will be lower. The lender also adds the borrower's current rent to the serviceability assessment. If total commitments exceed the lender's serviceability threshold, the application is declined or the loan amount is reduced.
You Must Commence Building Within a Set Period
Construction loan approvals are time-sensitive. Most lenders require you to commence building within six months from the disclosure date. If the build does not start within this window, the approval lapses and you must reapply.
Delays to council approval, site preparation, or builder availability can push your start date past the lender's deadline. If you anticipate delays, inform your broker before the approval expires. Some lenders will extend the commencement period, but this is not automatic. If rates have moved or your financial circumstances have changed, the lender may reassess the application under current criteria.
Additional Costs That Catch Applicants Out
Construction finance involves fees that do not apply to standard home loans. Most lenders charge a Progressive Drawing Fee each time funds are released, and some require payment for progress inspections. These costs are separate from the loan amount and must be paid upfront or capitalised into the loan.
Beyond lender fees, budget for site costs, soil tests, engineering reports, and connection fees for water, sewer, and electricity. If you are building on suitable land in a new estate, some of these costs may be included in the land price. If you are building on a rural block or a site with difficult access, expect additional charges. Lenders do not include these costs in the standard construction loan application, so underestimating them can leave you short when the builder is ready to start.
Why Getting Pre-Approval Matters Before You Sign
Getting loan pre-approval before signing a building contract protects you from committing to a build you cannot finance. Pre-approval confirms the loan amount a lender will provide, the interest rate structure, and any conditions that must be met before funds are released.
Without pre-approval, you risk signing a contract and paying a deposit, only to find that the lender will not approve the full amount or requires a larger deposit than you have available. Pre-approval does not lock in the loan, but it gives you a clear picture of what you can borrow and what documentation the lender will require. If you are building a custom design or working with a builder the lender does not recognise, pre-approval is the only way to confirm the loan will proceed.
Construction loan approval takes longer than a standard home loan and requires more documentation. If you are ready to start the process or want to check what a lender will require for your build, call one of our team or book an appointment at a time that works for you.
Frequently Asked Questions
What do lenders check when approving a construction loan?
Lenders assess your financial position, the builder's credentials, the fixed price building contract, and council approval for the development. They also verify that you can service both construction interest and your current housing costs during the build.
Can I get construction loan approval without a fixed price contract?
Most lenders will not approve construction funding without a fixed price building contract. Cost plus contracts or provisional sums may result in reduced loan amounts or declined applications.
How long does construction loan approval take?
Construction loan approval typically takes longer than standard home loan approval because lenders need to verify builder credentials, review contracts, and confirm council approval. Expect two to four weeks for a complete assessment, longer if documentation is incomplete.
Do I pay interest on the full loan amount during construction?
No. Lenders only charge interest on the amount drawn down at each stage of the build. Your repayments increase gradually as funds are released through the progress payment schedule.
What happens if I do not start building within six months of approval?
Most construction loan approvals require you to commence building within six months from the disclosure date. If you do not start within this period, the approval lapses and you must reapply under current lending criteria.
