Buying land to build a home requires different finance to a standard purchase.
You'll need a land and construction package that releases funds in stages as the build progresses, rather than a single upfront settlement. This protects both you and the lender, but it also means your loan works differently from day one. The application process involves more documentation, the interest rate structure can vary during construction, and you'll need council approval and a registered builder before funds are released.
How a Land and Construction Package Actually Works
A land and construction package is two facilities under one approval. The first component covers the land purchase and settles in full when you buy the block. The second component releases construction funding progressively as your builder completes key stages, from slab to frame to lock-up. You'll only pay interest on the amount drawn down at each stage, not the full loan amount, which keeps your repayments lower during the build.
Most lenders require you to commence building within a set period from the disclosure date, typically six to twelve months. If your council approval or builder contract isn't locked in before that deadline, you may need to renegotiate terms or switch lenders.
What Lenders Need Before They'll Approve Construction Finance
Lenders assess both your borrowing capacity and the viability of your build. You'll need a fixed price building contract with a registered builder, along with council plans showing the development application has been approved. The contract should include a progress payment schedule that matches the lender's construction draw schedule, which typically covers five to six stages from site preparation through to final completion.
Consider a buyer purchasing suitable land in Mornington close to the foreshore, intending to build a custom design home. The buyer's borrowing capacity covers the combined land and build costs, but the lender also reviews the builder's credentials, checks that the fixed price contract matches local construction costs, and confirms the design meets council approval conditions. Once satisfied, the lender issues a formal approval covering both the land purchase and progressive drawdown for the build.
How Interest Works During Construction
During the build, you'll typically move onto interest-only repayment options. Lenders only charge interest on the amount drawn down, so if your loan amount is approved at $800,000 but only $400,000 has been released for land and initial stages, your repayments reflect that lower balance. Each time your builder requests a progress payment, the lender arranges a progress inspection, then releases the next instalment.
Some lenders charge a progressive drawing fee each time funds are released, usually between $300 and $500 per drawdown. Others bundle this into the loan or waive it entirely. The interest rate during construction is often variable, even if you plan to fix the rate once the build is complete and you convert to a standard home loan.
Fixed Price Contracts Versus Cost Plus Arrangements
Most lenders prefer a fixed price building contract because it caps your exposure and theirs. A cost plus contract, where you pay the builder's actual costs plus a margin, introduces uncertainty around the final loan amount. Some lenders won't accept cost plus arrangements at all, while others will only consider them if you hold sufficient equity or cash reserves to cover potential overruns.
If you're engaging sub-contractors directly as an owner builder, construction loan options become more limited. Lenders view owner builder finance as higher risk because there's no registered builder providing statutory warranties, and the progress payment schedule is harder to verify. A small number of lenders offer owner builder finance, but expect higher interest rates and a larger deposit requirement.
The Progress Payment Schedule and How Inspections Work
Your builder submits a progress claim when each stage is complete. The lender arranges a progress inspection, usually through a third-party valuer or quantity surveyor, to confirm the work has been done to the required standard. Once the inspection is signed off, the lender releases the funds directly to the builder. You don't handle the payments yourself.
Typical stages include base stage (slab or stumps), frame stage, lock-up (roof and external walls complete), fixing stage (plumbing, electrical, plastering), and practical completion. Each stage represents a percentage of the total build cost, and your contract should clearly define what's included at each stage to avoid disputes.
What Happens When You're Ready to Move In
Once your builder reaches practical completion and you receive your occupancy certificate, the construction loan converts to a standard home loan. At this point, you can choose to fix your interest rate, switch to principal and interest repayments, or make additional payments without the restrictions that applied during the build.
Some buyers in Mornington are also considering knockdown rebuilds on existing properties rather than starting with vacant land. The process is similar, but you'll need to demonstrate where you'll live during construction, and the lender will assess the land value before demolition as part of your equity position. If this applies to your situation, or if you're renovating rather than building from scratch, the funding structure will look different again.
How Local Factors in Mornington Affect Your Application
Mornington's planning overlays and coastal proximity mean council approval timelines can stretch longer than in other suburbs. Lenders are familiar with the area, but they'll want to see that your development application addresses any environmental or heritage considerations before they'll issue formal approval. Blocks close to the foreshore or within character preservation zones may face additional restrictions that affect both your design and your approval timeline.
The local market also supports quality construction at a range of price points, from project home builders working with house and land packages through to custom builders working on architect-designed homes. Lenders will assess your builder's experience and financial stability as part of the approval process, so choosing a registered builder with a solid track record in the Mornington Peninsula will strengthen your application.
If you're also considering investment property or planning to rent the home initially, talk to a broker before you apply. The loan structure and deposit requirements differ when the property won't be your primary residence, and some investment loan products offer more flexibility for future refinancing once the build is complete.

Frequently Asked Questions
How does interest work during a construction loan?
You only pay interest on the amount drawn down at each stage, not the full loan amount. During construction, most borrowers use interest-only repayment options, which keeps costs lower until the build is complete and the loan converts to a standard home loan.
What's the difference between a fixed price contract and a cost plus contract?
A fixed price building contract sets a total cost upfront, which most lenders prefer because it caps your exposure. A cost plus contract charges the builder's actual costs plus a margin, which introduces uncertainty and is harder to finance.
Do I need council approval before applying for construction finance?
Yes, lenders require council plans showing your development application has been approved before they'll release funds. You'll also need a fixed price building contract with a registered builder as part of the application.
Can I act as an owner builder and still get a construction loan?
Some lenders offer owner builder finance, but it's considered higher risk and typically requires a larger deposit and higher interest rate. Most lenders prefer to work with registered builders who provide statutory warranties.
How long do I have to start building after the land settles?
Most lenders require you to commence building within six to twelve months from the disclosure date. If council approval or builder contracts aren't finalised within that timeframe, you may need to renegotiate terms or switch lenders.
