Unlock the secrets to knockdown rebuild finance

A knockdown rebuild on Hope Island gives you a modern home tailored to your needs without leaving one of the Gold Coast's most connected waterfront communities.

The funding structure for a knockdown rebuild is different from buying an existing home. Lenders release the loan amount progressively as each stage of construction is completed, and you'll only be charged interest on the amount drawn down at any given time. Understanding how progressive drawdowns work, what council approval involves, and how to structure your deposit will determine whether your project moves forward or stalls before it starts.

How Construction Loans Differ From Standard Home Loans

A construction loan releases funds in stages as your registered builder completes specific milestones, not as a single upfront sum. Each drawdown requires a progress inspection before the lender releases payment, and you'll pay interest only on the portion that's been drawn down, not the full loan amount. Most lenders also charge a Progressive Drawing Fee, typically between $800 and $1,500, to cover the cost of site inspections and administration throughout the build.

Consider a buyer purchasing a property on Hope Island with an older home to demolish. The land component settles first, and the buyer pays interest on that portion while waiting for council approval and demolition. Once the registered builder begins, funds are released at stages such as slab down, frame up, lock-up, fixing, and practical completion. At the frame-up stage, if $150,000 has been drawn, interest is calculated on that amount, not the total approved loan.

What Council Approval Means for Your Timeline

You need development application approval from the Gold Coast City Council before demolition and construction can begin. The approval process typically takes between six and twelve weeks, depending on the complexity of your custom design and whether any variations are required. Most lenders require you to commence building within a set period from the Disclosure Date, usually six to twelve months, so delays in council approval can affect your loan conditions.

Hope Island sits within an established master-planned community, and certain design guidelines apply depending on the estate or precinct. Some lenders will approve your construction loan conditionally while council plans are being finalised, but they won't release the land funds until all approvals are in place. If your development application requires amendments or neighbour consultation, factor in additional time before your builder can mobilise.

Fixed Price Contracts and How They Protect You

A fixed price building contract locks in the total construction cost before you apply for finance, which gives the lender certainty and protects you from cost overruns during the build. The contract should include a detailed progress payment schedule that aligns with the lender's drawdown stages, and it must be signed by a registered builder who holds the appropriate licenses in Queensland.

Lenders assess your construction loan application based on the combined land value and the contracted build price. If you're purchasing a knockdown rebuild property on Hope Island for $650,000 and your build contract is $480,000, the lender evaluates a total project cost of $1,130,000. Your deposit, usually 10% to 20%, applies to this combined figure. Without a fixed price contract, most lenders won't proceed, and cost plus contracts are rarely accepted for standard residential knockdown rebuilds.

How the Progress Payment Schedule Works

The progress payment schedule outlines when funds are released during construction, and it should match the stages listed in your building contract. Typical stages include base stage, frame stage, lock-up stage, fixing stage, and practical completion. Your builder requests each drawdown, the lender arranges a progress inspection, and once the stage is verified, the funds are paid directly to the builder.

In a scenario where the frame stage represents 25% of the build cost, and your contracted build price is $480,000, the lender releases $120,000 at that point. If the inspection reveals the frame isn't complete or doesn't meet the building code, the drawdown is delayed until the work is rectified. This progressive drawdown structure means your builder is paid as they deliver, which reduces financial risk for both you and the lender.

What Happens to Your Existing Loan if You Own the Land

If you already own the property and are demolishing an existing home, your current home loan may need to be refinanced into a construction facility. Not all lenders offer construction loans, so you might need to move to a different lender to access construction loan options from banks and lenders across Australia. This process involves discharging your current mortgage, settling the new construction loan, and then commencing the build once council approval is in place.

Some lenders allow you to retain your existing loan for the land component and add a separate construction facility on top, but this depends on your borrowing capacity and the lender's policy. If your existing loan has a low interest rate or offset account with significant funds, refinancing into a construction loan might cost you more in the long term. Comparing the total interest cost across both the construction phase and the life of the loan will show you which structure makes sense.

Deposit Requirements and Genuine Savings

Most lenders require a deposit of at least 10% of the total project cost, including both land and construction. If your deposit is less than 20%, you'll pay Lenders Mortgage Insurance, which is calculated on the full loan amount and adds to your upfront costs. Lenders also assess whether your deposit comes from genuine savings, which means funds held in your account for at least three months, rather than a recent gift or loan from family.

For a knockdown rebuild project with a total cost of $1,130,000, a 10% deposit is $113,000. If you're relying on equity from another property, the lender will value that property and allow you to borrow against it, but you'll still need to demonstrate genuine savings or funds for settlement costs. First home buyers using the First Home Owner Grant or stamp duty concessions should confirm eligibility with the Queensland Revenue Office, as knockdown rebuilds are treated differently from purchasing vacant land.

Interest-Only Repayments During Construction

During the construction phase, most lenders offer interest-only repayment options, which means you only pay interest on the amount drawn down each month. Once construction reaches practical completion and you move in, the loan converts to a standard principal and interest home loan, or you can choose to remain on interest-only for a set period if your lender allows it.

Interest-only repayments reduce your monthly outgoings while the build is underway, which is useful if you're also paying rent or covering costs on another property. The interest rate during construction is typically variable, though some lenders offer fixed rate options once the loan converts to a standard mortgage. Choosing between variable and fixed depends on your plans after moving in and whether you want certainty over repayments or the flexibility to make additional payments without penalty.

Who Can Help You Compare Construction Lenders

Not all lenders offer construction loans, and those that do have different policies on progress inspections, drawdown timing, and owner builder finance. Working with a broker who understands construction funding means you can compare lenders based on the Progressive Drawing Fee, interest rate, and how quickly they process drawdown requests during the build.
