Top tips to secure finance for land purchase & construction

Buying land and building lets you design the home you want instead of compromising on what's already built.

The process works differently to a standard home loan. You'll need a land and construction package that covers the land purchase first, then releases funds progressively as your registered builder completes each stage of the build. Lenders only charge interest on the amount drawn down at each stage, so you're not paying interest on the full loan amount while the slab is being poured.

Consider a buyer purchasing a block in a new estate who wants to engage a custom builder. They secure finance approval for the land first, then lock in a fixed price building contract. Once council plans are approved and the builder is ready to start, the lender releases funds at agreed milestones such as slab, frame, lock-up, fixing, and completion. Each release is triggered by a progress inspection to confirm the work matches the progress payment schedule.

How construction finance differs from a standard home loan

A construction to permanent loan is structured in two phases. During construction, you typically make interest-only repayment options on the amount drawn down so far. Once the build is complete and you've moved in, the loan converts to principal and interest repayments like a standard mortgage.

The land component usually settles first. If you're buying in a new estate, you'll need to settle on the block before construction can begin. Some lenders require you to commence building within a set period from the Disclosure Date, often six to twelve months, to keep the approval valid. If council approval or your building contract takes longer than expected, you may need to request an extension or reapply.

Funding is released according to a Progressive Payment Schedule that aligns with your fixed price building contract. Your builder will request payment after completing each stage, the lender arranges a progress inspection to verify the work, then releases the instalment. Most lenders charge a Progressive Drawing Fee each time funds are released, usually between two hundred and six hundred dollars per drawdown depending on the lender.

What lenders look for in a construction loan application

Lenders assess the land value, the builder's credentials, and your ability to service the final loan amount. The land needs to be suitable for construction, meaning it has council approval for residential development and access to essential services. If you're buying rural land or a block that requires a development application, some lenders will decline or require a larger deposit.

Your builder must be a registered builder with appropriate licensing and insurance. Most lenders won't finance owner builder projects unless you hold a builder's licence yourself, and even then, owner builder finance options are limited to a handful of specialist lenders. The building contract should be a fixed price contract, not a cost plus contract, because lenders want certainty over the final loan amount.

Your serviceability is calculated on the full loan amount even though you'll only be paying interest on progressively drawn funds during construction. That means you need to demonstrate you can afford the principal and interest repayments once the build is finished and the loan converts. Lenders will also review the contract price against the expected value of the completed home to ensure the loan to value ratio sits within their policy, usually capped at eighty or ninety percent depending on whether you're an first home buyer or investor.

The progressive drawdown process and timing

Once your builder is ready to start, they'll request the first drawdown to cover the slab and base stage. You notify your lender or broker, the lender sends an independent inspector to verify the stage is complete, then releases funds directly to the builder within a few days. This cycle repeats at each milestone: frame, lock-up, fixing, and practical completion.

Timing matters because builders expect payment within a set window after completing each stage. If the inspection is delayed or the lender's process is slow, your builder may pause work until they're paid. That's why it's worth confirming your lender's turnaround time for inspections and drawdowns before you sign the building contract. Some lenders process inspections within forty-eight hours, others take a week or more.

Between drawdowns, you're only paying interest on the amount already released. If two hundred thousand dollars has been drawn down and your construction loan interest rate is six percent, you're paying around one thousand dollars per month in interest during that period. As more funds are released, your interest cost increases, but you're still not servicing the full loan until construction is complete.

Council approval and contract requirements

Your lender will need a copy of the council plans and building permit before they'll release the first drawdown. If you're building a custom design, this can take several months from the time you engage an architect or draftsperson to the time council issues the permit. Most lenders are comfortable waiting as long as the land has settled and you're making progress, but some will only hold the approval open for a set period.

The fixed price building contract must include a detailed progress payment schedule that breaks down how much is due at each stage. Lenders won't accept vague payment terms or contracts that leave the final price open-ended. The contract should also specify who is responsible for site costs, authority fees, and any additional payments for upgrades or variations. If the contract price increases after approval, you may need to cover the difference from your own funds unless you reapply for a higher loan amount.

For house & land packages offered by volume builders, the process is usually more straightforward because the builder provides a standard contract and the estate developer has already obtained council approval for the subdivision. The builder submits the contract and plans to your lender, and as long as the numbers align, the approval moves ahead without delays.

Fixed versus variable rates during construction

Most lenders offer both fixed and variable construction loan interest rate options, but the structure during construction is almost always variable with interest-only repayments. Once the build is complete, you can choose to fix the rate, stay variable, or split between the two.

Some borrowers lock in a fixed rate at the start of construction to protect against rate rises while the build progresses. Others prefer to stay variable during construction because they plan to make additional payments or refinance once the home is complete. There's no universal answer, it depends on your risk tolerance and how long the build will take.

If you're building in a growth area and expect the completed home to be worth significantly more than the contract price, you may have access to better loan terms or a lower rate once the property is revalued at practical completion. That's worth discussing with your broker before you commit to a fixed rate during construction.

Who construction finance suits beyond custom builds

While most people think of construction finance as funding for a custom design built from scratch, the same loan structure applies to project home loans, house renovation loans, and even off the plan finance where the builder hasn't started yet. If you're buying a house & land package in a new estate, you're using a land and build loan even if the builder is using a standard floor plan.

Construction finance also covers substantial renovations where you're adding a second storey, extending the floor plan, or rebuilding after a demolition. Lenders treat this as construction funding and release funds progressively as the work is completed, just like a new build. You'll still need fixed price contracts, progress inspections, and a registered builder, but the loan amount might also include the purchase price of the existing property if you're buying a knockdown rebuild.

Investment loans for new builds follow the same structure, with the added complexity that lenders assess rental income on the completed property rather than current income. If you're building an investment property, your broker will need to provide a rental appraisal to support the serviceability calculation.

Working with plumbers, electricians, and sub-contractors

Your builder is responsible for paying sub-contractors like plumbers and electricians from the funds released at each stage. You don't pay them directly unless you're acting as an owner builder, which most lenders won't finance unless you're licensed.

If your builder runs into financial trouble or fails to pay sub-contractors, those tradespeople may lodge a caveat against your land to secure payment. That can delay completion and create legal complications even though you've already paid the builder. This is why lenders insist on registered builders with appropriate insurance and why it's worth checking your builder's financial position before signing the contract.

Most states require builders to hold contract works insurance and last resort insurance to protect you if the builder goes insolvent mid-project. Your lender will ask for evidence of this insurance before releasing funds. If the builder can't provide it, the loan approval may be withdrawn.

Choosing the right lender for your build

Not all lenders offer construction finance, and those that do have different policies on land types, builder requirements, and drawdown processes. Some lenders will only finance house & land packages from approved builders, while others will consider custom builds and renovations. A handful of lenders specialise in construction to permanent loans and offer faster turnaround times on inspections and drawdowns.

Your broker can access construction loan options from banks and lenders across Australia, which means you're not limited to your current bank or the lender your builder recommends. Different lenders have different appetites for rural land, split-level designs, or builds that exceed a certain contract price. If one lender declines, another may approve based on their specific policy settings.

The construction loan interest rate is only one factor. Drawdown fees, inspection turnaround times, and the lender's willingness to extend the approval period if your build is delayed all matter just as much. A lender with a slightly higher rate but faster processing can save you money if it means your builder stays on schedule and you're not paying holding costs on temporary accommodation while waiting for funds to be released.
