A knockdown rebuild in Kingscliff lets you stay in the area you love without compromising on the home you want.
Most buyers assume they need to sell their existing property first, or that they'll be stuck paying two mortgages during construction. A construction loan structured properly avoids both issues. You only pay interest on what's been drawn down, which means your repayments grow gradually as the build progresses. If you're living elsewhere during construction, you're not covering the full loan amount from day one.
Kingscliff's older beach houses sit on some of the most sought-after land between the Tweed and the coast. Knocking down and rebuilding means you keep the location, the established gardens, and the lifestyle, while creating a home that suits how you actually live. The funding side just needs to be set up in the right order.
How construction finance differs from a standard home loan
A construction loan releases funds in stages as the build progresses, not as a lump sum at settlement. The lender holds the full approved amount but only advances it when your builder reaches specific milestones. You pay interest on what's been drawn, not the total loan amount, which keeps repayments lower during the build.
Consider a scenario where you're knocking down a fibro cottage in Kingscliff and building a new home. Your land is already owned and the build cost is being released over five stages. After the slab is poured, you might have drawn down 20% of the construction amount. Your interest is calculated on that portion, plus any land component if you've refinanced to release equity. As framing is completed, the next draw happens. Your repayments increase incrementally, which makes budgeting more predictable than covering the full loan from the start.
Lenders assess construction loans differently to standard home loans. They want to see council approval, a fixed price building contract with a registered builder, and enough equity or deposit to cover both the land value and construction cost. If you own the land outright, that equity usually covers a significant portion of the total project. If you're refinancing an existing mortgage on the property, the lender will assess your borrowing capacity based on the completed value of the new home, not the current dwelling.
What lenders need to see before approving a knockdown rebuild
Council approval comes first. Lenders won't release construction funds without a development application that's been stamped and approved. In Kingscliff, this process usually involves Tweed Shire Council, and it can take several months depending on the complexity of the design and whether you're in a flood-prone area or near the coastal zone. Your builder or architect will typically handle this, but the lender will want a copy of the final approval before settlement.
A fixed price building contract with a registered builder is non-negotiable for most lenders. They need certainty around the build cost and a clear schedule of progress payments. The contract should outline exactly when each drawdown will occur, tied to physical stages like slab, frame, lockup, fixing, and practical completion. Cost plus contracts, where the final price can vary, are harder to fund because the lender can't lock in a maximum exposure.
Construction loans are structured around this progress payment schedule. Each time your builder reaches a milestone, they'll request a draw. The lender will send a valuer or building inspector to confirm the work is complete, then release the funds directly to the builder. This process is called progressive drawdown, and it protects both you and the lender by ensuring money is only paid for work that's actually been done.
The equity position that makes a knockdown rebuild work
You need enough equity in the existing property to cover the full project cost without exceeding the lender's maximum loan-to-value ratio. Most lenders will lend up to 80% of the completed value, which means you need at least 20% equity after accounting for both the land and the build.
In our experience, Kingscliff buyers knocking down an older home usually have significant equity already. If your property is unencumbered or has a small remaining mortgage, that equity becomes your deposit. The lender values the land based on its current market value, not the value of the house that's about to be demolished. That land value, combined with the projected value of the completed home, gives the lender their security position.
If your equity falls short, you'll either need to bring in additional savings or adjust the build scope. Some buyers choose a slightly smaller design or defer landscaping to a later stage. Others might consider using a family guarantor to cover the shortfall, though that introduces complexity and risk for the guarantor.

How the drawdown schedule affects your cash flow during construction
You start paying interest as soon as the first draw is released. That's usually at slab stage, which means you'll have a few months of no repayments while the site is cleared and footings are poured. Once the slab is down, the first progress payment is made and interest starts accruing on that portion.
Most lenders offer interest-only repayment options during construction, which keeps your payments lower while you're managing other costs like temporary accommodation or storage. Once the build is complete and you've moved in, the loan typically converts to a standard principal and interest home loan. Some lenders offer a construction to permanent loan, which rolls the construction phase and the ongoing mortgage into one approval, avoiding the need to reapply once the build is finished.
The progressive drawing fee is charged each time the lender releases funds. It's usually a few hundred dollars per draw, and it covers the cost of the valuation or inspection. Over a typical five-stage build, you're looking at a total of around $1,500 to $2,000 in these fees. That's separate from your ongoing interest, and it's worth budgeting for upfront so it doesn't catch you off guard.
When to lock in your rate and what happens if the build runs over
Most construction loans start on a variable rate during the building phase, then give you the option to fix once the home is complete. Locking in a rate before construction starts can be risky because build timelines can stretch, and fixed rate periods start ticking from the date of the first draw, not from completion.
If your build takes longer than expected, and you've fixed your rate, you might end up with only a year or two remaining on your fixed term by the time you move in. Depending on your construction timeline and the current rate environment, it might make sense to stay variable during the build and fix once you've reached practical completion. Your mortgage broker in Kingscliff can walk through the timing with you based on your builder's schedule.
Some lenders allow you to lock in a rate for up to 12 months before the first draw, which can be useful if rates are climbing and you want certainty. Just make sure your builder's timeline aligns with that window, or you'll end up paying a higher rate than necessary or facing break costs if the build delays.
What happens if you're living in the existing home during demolition
If you're planning to stay in the existing house right up until demolition, your lender will want to know where you'll live during the build. Some buyers move into a rental nearby, others stay with family, and some use a caravan on-site if council permits it. The lender doesn't usually require proof of accommodation, but they will want to know that you can afford both your construction loan repayments and your living costs during that period.
If you're renting elsewhere while the build happens, that's an additional cost to factor into your cash flow. A modest rental in Kingscliff or nearby Tweed Heads might run $600 to $800 per week depending on the size and proximity to the beach. That's on top of your construction loan interest, which is why the progressive drawdown structure is so important. You're not paying interest on the full build cost from day one, which leaves more room in your budget for rent.
Alternatively, some buyers choose to sell their existing home before demolition and rent back from the buyer for a short period, or negotiate a longer settlement to give them time to secure temporary accommodation. That approach works if the buyer is an investor or if the property is already quite run down and they're purchasing for the land value anyway.
How to prepare your application before you approach a lender
Start with a clear build cost. Get quotes from at least two registered builders and choose the one whose contract is most detailed. Lenders will scrutinise the contract, and anything vague or open-ended will slow down your approval. The contract should list every inclusion, every exclusion, and every stage of the progress payment schedule.
Have your council approval in hand, or at least well progressed. Lenders can provide conditional approval before the DA is finalised, but they won't release funds until it's stamped. If you're in a flood zone or building close to the foreshore in Kingscliff, expect the DA process to take longer and involve more conditions. Your builder will know the local requirements, but it's worth flagging this early with your broker so the lender's expectations are set.
If you're refinancing your existing mortgage to fund the knockdown rebuild, gather your current loan statements and any other debts you're carrying. The lender will assess your borrowing capacity based on your income, existing commitments, and the projected value of the new home. If you're self-employed or have income from multiple sources, having your financials organised upfront will speed up the process. Self-employed loans can take a bit longer to assess, so starting early gives you more time to address any questions the lender raises.

Frequently Asked Questions
How does a construction loan work for a knockdown rebuild?
A construction loan releases funds in stages as your builder completes specific milestones, not as a lump sum. You only pay interest on the amount drawn down at each stage, which keeps repayments lower during the build and increases gradually as the project progresses.
What do lenders need to approve a knockdown rebuild in Kingscliff?
Lenders require council approval from Tweed Shire Council, a fixed price building contract with a registered builder, and enough equity in your property to cover the land and construction costs. Most lenders will lend up to 80% of the completed home's value.
Can I lock in my interest rate before construction starts?
Most construction loans start on a variable rate during the building phase, with the option to fix once complete. Locking in a rate before construction can be risky if the build runs over, as your fixed term starts from the first drawdown, not from completion.
Do I need to move out before demolition starts?
Yes, you'll need alternative accommodation once demolition begins. Some buyers rent nearby, stay with family, or negotiate a rent-back arrangement if they sell before demolition. Lenders will want to confirm you can manage both construction loan repayments and living costs during this period.
What happens if my build takes longer than expected?
If your build delays and you've locked in a fixed rate, you may have less time remaining on your fixed term by the time you move in. Staying variable during construction and fixing once you reach practical completion can avoid this issue, depending on the rate environment.
