What a Construction Loan Covers When You Buy Land
A construction loan lets you purchase land and fund the build in one arrangement. The lender approves the total amount upfront, then releases funds in stages as your registered builder hits each milestone, which means you only pay interest on what's been drawn down at each point rather than the full amount from day one.
You'll need council approval and fixed price building contract before settlement. Most lenders also want the build to start within six to twelve months of buying the land, so your timeline matters from the moment you sign the contract.
How Progressive Drawdown Works in Practice
Consider a scenario where you're buying land and building with a project home builder under a fixed price contract. The lender holds the full loan amount but releases it in instalments tied to your builder's progress payment schedule. A typical schedule might include base stage, frame stage, lock-up, fixing stage, and practical completion. At each stage, the builder requests payment, the lender arranges a progress inspection, and once that clears, the funds go directly to the builder.
Between stages, you're only charged interest on what's been released so far. If the land cost $200,000 and the first two progress payments total $150,000, your interest calculation sits at $350,000 until the next drawdown. That structure keeps your repayments lower during construction compared to a standard home loan where the full balance is owing from settlement.
Lenders typically charge a Progressive Drawing Fee for each inspection and release, which can run anywhere from $200 to $500 per stage depending on the lender and the number of draws in your contract.
Fixed Price Contracts and Why Lenders Require Them
Most lenders will only approve construction finance if you're working with a registered builder under a fixed price building contract. That contract locks in the build cost and protects both you and the lender from cost blowouts or incomplete projects. A cost plus contract, where expenses are reimbursed as they occur, is harder to finance and generally only available to owner builders or through specialist lenders.
The fixed price arrangement also simplifies the drawdown process because the progress payment schedule is attached to the contract upfront. Your broker can send that schedule to the lender during the application, and the lender structures the loan around those agreed stages.

Interest-Only Repayments During Construction
During the build phase, most construction loans default to interest-only repayment options. You're not required to pay down principal until the build is finished and the loan converts to a standard home loan. That gives you breathing room if you're renting or still living elsewhere while the house goes up, since your monthly outgoings stay lower until you move in.
Once practical completion is signed off, the loan switches to principal and interest repayments unless you've negotiated an ongoing interest-only period. If you're planning to live in the property and your budget's tight during the build, factor in the jump in repayments once construction wraps up.
Owner Builder Finance and What Changes
If you're an owner builder, your options narrow. You'll need to show relevant building experience or qualifications, and the lender will likely cap the loan amount at a lower percentage of the property's end value compared to a registered builder arrangement. Progress inspections become more detailed, and you may need to provide invoices from sub-contractors like plumbers and electricians before each drawdown is approved.
Owner builder finance also tends to attract higher interest rates and stricter conditions around progress payment finance, since the lender carries more risk if the project stalls or runs over budget. For most people working full-time on shift, it's not a practical path unless you've got trade experience and the leave to manage the build.
Land and Build Loans for Police Officers
If you're eligible for an LMI waiver through your role, that applies to the full land and construction package, not just the land component. A waiver can let you borrow up to 90% of the combined land and build cost without paying lenders mortgage insurance, which on a $500,000 project could save you around $15,000 to $20,000 in upfront costs. You'll find more detail on how those waivers work and which lenders offer them in our guide to LMI Waivers for Police Officers.
The same shift work and overtime rules apply during the construction loan application as they would for a standard purchase. Your base salary is assessed at full value, and any regular allowances or overtime that's been consistent over the past 12 months can usually be included when the lender calculates your borrowing capacity. More on that in our section on Borrowing Capacity.
What Happens if the Build Runs Over Time
If your builder misses deadlines or the build drags out beyond the original schedule, your construction loan doesn't automatically convert until practical completion is certified. That means you'll stay on interest-only repayments for longer than planned, which might suit your cash flow but delays the point where you start building equity through principal repayments.
Some lenders set a maximum construction period, usually 12 to 18 months from the first drawdown. If the build runs beyond that, they may review the loan or adjust the terms. It's not common, but it's worth asking your broker upfront what the lender's policy is if delays happen outside your control.
Getting Pre-Approval Before You Buy the Land
Pre-approval for a construction loan works differently to a standard purchase because the lender needs to see both the land contract and the building contract before they'll give full approval. You can get conditional approval based on the land alone, but that approval is subject to the lender reviewing and accepting your builder's quote and contract once you've locked that in.
If you're looking at land in a new estate where house and land packages are common, some developers have preferred builder lists that streamline the process. Either way, don't exchange on the land until your broker has confirmed the lender is comfortable with your builder's credentials and the proposed build cost. More about the pre-approval process in our guide to Getting Loan Pre-Approval.
Moving from Construction Loan to Standard Home Loan
Once the build is finished and you've got your occupancy certificate, the lender conducts a final valuation to confirm the property's end value matches or exceeds the loan amount. Assuming that checks out, the construction loan converts to a standard home loan with principal and interest repayments, and you can start making additional payments or refinancing if a better rate is available elsewhere.
If you've built well and the market's been kind, the end value might come in higher than the total amount you borrowed for land and construction. That instant equity can give you options down the line if you're looking to buy an investment property or access funds for other purposes.

Frequently Asked Questions
Do I pay interest on the full loan amount during construction?
No, you only pay interest on the amount drawn down at each stage. As the builder reaches each milestone and funds are released, your interest calculation increases to match the new balance.
Can I use an owner builder arrangement with a construction loan?
Some lenders allow it, but you'll need to show relevant building experience and the loan amount will likely be capped at a lower percentage. Rates are also higher and the approval process is more involved.
What happens if my build takes longer than expected?
You stay on interest-only repayments until practical completion is certified. Most lenders allow 12 to 18 months for construction, and if it runs beyond that they may review the loan terms.
Do LMI waivers for police officers apply to land and construction loans?
Yes, if you're eligible for an LMI waiver it applies to the combined land and build cost, not just the land. You can borrow up to 90% without paying lenders mortgage insurance.
When does the loan convert to a standard home loan?
Once the build is finished and you receive your occupancy certificate, the lender conducts a final valuation and converts the loan to principal and interest repayments. This usually happens within a few weeks of practical completion.
