What are Construction Loans for Land and Building

A construction loan for purchasing land and building a home is structured differently to a standard mortgage because the bank releases funds progressively as your build reaches set milestones.

You're essentially managing two separate stages: the land purchase happens first with a single settlement, then construction funding is released in instalments tied to your builder's progress payment schedule. The structure protects both you and the lender by ensuring money flows only when verifiable work is complete.

How a Land and Construction Package Actually Works

The loan splits into two components that operate on different timelines. The land portion settles in full when you take ownership of the block, and from that point you'll start making repayments on that amount. Construction funding sits approved but undrawn until your registered builder submits a claim after completing a stage like slab or frame.

Consider a buyer purchasing a block for $180,000 and building a home with a fixed price building contract of $420,000. Once the land settles, they'll pay interest only on $180,000 while waiting for council approval and the builder to start. As each stage completes, the lender conducts a progress inspection before releasing the next draw. By frame stage, the total drawn might reach $300,000, and interest adjusts with each release. This means you only pay for funds you've actually used, which keeps costs lower during construction than if the full loan amount was drawn upfront.

What Lenders Look for in a Construction Loan Application

Approval depends on the land being suitable for construction, the builder being properly licensed and insured, and you having a fixed price contract that locks in the total cost. Most lenders won't approve funding if you're building as an owner builder or using a cost plus contract where the final price can shift.

Your development application and council approval must be either granted or clearly progressing. Lenders typically require you to commence building within a set period from the disclosure date, often six to twelve months, so buying land without immediate plans to build can complicate approval. The loan amount is assessed against the combined value of land plus completed dwelling, not just the land alone, which usually means you'll need a deposit of at least 10% of the total project cost.

The Progressive Drawing Fee and How It's Structured

Each time the builder requests a progress payment, the lender arranges an inspection and processes the drawdown. Most lenders charge a progressive drawing fee for this service, typically between $300 and $600 per draw, though some waive it entirely depending on the loan structure.

A standard progress payment schedule has five or six stages: deposit, base or slab, frame, lockup, fixing, and practical completion. If your lender charges $400 per draw across six stages, that's $2,400 in fees built into your total project cost. Some lenders bundle this into a single upfront fee, others charge per inspection. Knowing the structure before you sign helps you budget accurately and avoid surprise costs mid-build.

Interest-Only Repayment Options During Construction

Most construction loans default to interest-only repayments during the build, which means your monthly commitment stays manageable while funds are being progressively drawn. Once construction reaches practical completion, the loan typically converts to principal and interest repayments based on the full amount.

In our experience, buyers underestimate how long the construction phase actually takes. A build quoted at six months often stretches to nine or ten once you factor in weather delays, material supply issues, and the time between progress inspections. Locking in interest-only repayments for at least twelve months gives you breathing room without needing to request an extension partway through. Some lenders allow you to make additional payments during construction without penalty, which can reduce your balance before the loan converts to principal and interest.

Fixed Versus Variable Rates on Construction Finance

You can fix the construction loan interest rate from the start, but the rate applies only to funds already drawn down. If you fix at 6.2% and only $150,000 has been released, that portion is locked while the remaining approved amount sits undrawn and won't be fixed until it's released in a later stage.

Some lenders offer a rate lock option where you can secure the rate before the first draw, which protects you if rates rise during the build. Others apply the current variable rate to each new drawdown, meaning your interest rate could shift between stages if the market moves. If rate stability matters to you, look for lenders offering upfront rate locks or consider splitting the loan so construction funding sits on a variable rate and converts to fixed once building completes. This approach gives you flexibility during the build and certainty once you're making full repayments.

Council Approval and Builder Requirements

Lenders won't release construction funds until you provide evidence of council plans approval and building insurance. Your registered builder must hold the required licenses for your state, and their contract needs to clearly outline the progress payment schedule with dollar amounts tied to each stage.

If council approval is delayed or conditional, your construction loan approval may lapse before you're ready to start. Most approvals are valid for six to twelve months, so if you're still waiting on a development application to be finalised, it's worth discussing timeframes with your broker before committing to the land purchase. Buying land subject to council approval is common, but your finance approval will be similarly conditional, which means both need to align before settlement proceeds.

Why a Fixed Price Contract Matters

A fixed price building contract specifies the total build cost and breaks it into stages with set dollar amounts for each progress payment. Lenders need this certainty because the loan is approved against a known project cost, and if that cost blows out mid-build, the additional funding won't automatically be available.

Cost plus contracts, where you pay for materials and labour as they're incurred plus a builder's margin, introduce too much uncertainty for most lenders. Without a fixed total, the lender can't assess your capacity to service the debt or confirm the completed property will be worth enough to secure the loan. If your builder only offers cost plus arrangements, your finance options will narrow significantly. Securing a fixed price contract before applying for finance removes that risk and keeps the approval process straightforward.
