Everything You Need to Know About Knockdown Rebuild Loans

A knockdown rebuild lets you stay in the location you want while building exactly the home you need.

If you already own land in Ormeau or you're buying an older home on a block you love, construction finance for a knockdown rebuild works differently to a standard home loan. The lender releases funds in stages as your builder completes each phase, and you only pay interest on what's been drawn down. That structure protects both you and the lender, but it also means your application needs to show council approval, a fixed price building contract, and enough buffer in your borrowing capacity to cover the full loan amount once construction is complete.

How construction finance differs from a standard home loan

Construction finance is released progressively, not as a lump sum. Your lender will hold the loan amount and release it in stages, typically five or six draws, as your builder hits key milestones like slab down, frame up, lockup, fixing, and practical completion. Between draws, you're only charged interest on the amount already released, which keeps your repayments lower during the build. Once construction is complete, the loan converts to a standard home loan with principal and interest repayments, assuming you've chosen a construction to permanent loan structure.

Most lenders also charge a Progressive Drawing Fee each time they release funds. That fee covers the cost of a progress inspection, where a valuer or building consultant visits the site to confirm the work matches the stage your builder is claiming. The fee is usually between $200 and $400 per draw, and it's deducted from the amount released rather than paid upfront.

What lenders look for in a knockdown rebuild application

Lenders need to see that your project is viable and that you can service the full loan once the build is complete. You'll need council approval or a development application that's well progressed, a fixed price building contract with a registered builder, and proof that the build will commence within a set period from the contract date, usually six months. The contract should include a progress payment schedule that matches the lender's draw stages, and your builder needs appropriate insurance, including home warranty cover.

Your borrowing capacity is assessed on the final loan amount, not the progressive draws. That means your income needs to support the full repayment from day one, even though you'll only be paying interest on a portion of the loan during construction. In our experience, buyers sometimes assume they can stretch further because the initial repayments are lower, but the lender will test you at the full amount plus a buffer, usually around 3% above the actual interest rate.

The construction draw schedule and how it affects your cash flow

A typical construction draw schedule in Ormeau might include a deposit paid on contract signing, then five or six progress payments as the build advances. The deposit, usually 5% or 10%, comes from your own savings and is paid before the lender releases anything. After that, the lender releases funds at slab stage, frame stage, lockup, fixing, practical completion, and final completion. Some lenders front-load the early draws, while others spread them more evenly. The exact split depends on your lender and your builder's payment structure.

Consider a family knocking down an older weatherboard on a 600-square-metre block near Ormeau Town Centre. They've secured a fixed price contract for $480,000, and the land is already paid off. Their lender structures the draws as 15% at slab, 20% at frame, 25% at lockup, 20% at fixing, 15% at practical completion, and 5% at final. During the six-month build, their repayments start at around $450 per month after the first draw and climb to roughly $1,800 by lockup, based on current variable rates. Once construction finishes, they move to full principal and interest repayments of around $2,600 per month. Because they planned for that final figure from the start, the transition doesn't strain their budget.

Fixed price contracts and cost plus structures

Most lenders will only approve construction finance against a fixed price building contract. That contract locks in the total build cost, so the lender knows exactly how much they're funding and you know what you're committing to. A fixed price contract protects you from cost blowouts, and it gives the lender confidence that the project won't stall halfway through because the money ran out.

A cost plus contract, where you pay the builder's costs plus a margin, is harder to finance because the final price isn't fixed. Some lenders will consider it if you're using a well-known builder and you've built in a substantial contingency, but most prefer fixed price. If you're planning a custom design with finishes that might change during the build, work with your builder to set a fixed price with a provisional sum for items like tiles or joinery, rather than leaving the whole contract open-ended.

Land and construction packages versus knockdown rebuilds on your own block

A land and construction package bought together is slightly more straightforward to finance because the land and build are contracted at the same time, often with the same developer. A knockdown rebuild on land you already own, or on a block you're buying separately, involves two separate transactions. You need to settle the land purchase, get council approval to demolish and rebuild, then start construction, all while managing the timeline so your finance approval doesn't expire.

In Ormeau, where you might be buying an older home on suitable land near Pimpama State Secondary College or closer to the M1, the land purchase and the construction loan can be structured as a single approval with two settlements. You settle the land first, your builder starts work once the existing structure is removed, and the construction draws follow the usual schedule. The advantage is that you control the land and the build separately, so you're not locked into a house and land package that might not suit your block or your lifestyle.

Owner builder finance and why it's harder to secure

If you're planning to manage the build yourself, owner builder finance is much harder to arrange. Lenders see owner builders as higher risk because there's no fixed price contract, no builder's warranty, and no guarantee that the project will be completed on time or on budget. Most mainstream lenders won't touch it, and the few that do will require a larger deposit, charge a higher interest rate, and cap the loan at a lower percentage of the finished value, often 60% to 70% instead of the usual 80% or more.

If you're set on managing the build, expect to fund a significant portion yourself and to provide detailed costings for every stage, including quotes from plumbers, electricians, and other sub-contractors. The lender will want to see that you've worked in construction or have relevant experience, and they'll often require a quantity surveyor's report to verify your budget.

How long the application takes and what holds it up

A construction loan application usually takes two to four weeks from submission to formal approval, assuming your documentation is complete. The main delays come from waiting on council approval, getting a valuation that reflects the finished value rather than the existing structure, and finalising the building contract with all the schedules and insurance in place. If you're knocking down an older home in Ormeau, the valuer needs to assess the land value plus the proposed build, which can take longer than a standard purchase valuation.

Once you've got formal approval, most lenders give you six months to start construction. If your builder can't begin within that window, you'll need to extend the approval or reapply, which can mean reassessing your income and serviceability under whatever rules are current at that time.

Interest-only repayments during construction and after

During the build, you're automatically on interest-only repayments because there's no principal to repay yet. The lender only charges interest on the amount drawn down, so your repayments grow as each stage is funded. Once construction is complete and the loan converts to a standard home loan, most lenders will offer the option to continue on interest-only for a period, usually one to five years, before switching to principal and interest. That can help if you've just moved into a new home and you're managing other costs like landscaping, fencing, or furniture, but it also means you're not reducing the debt.

If your goal is to build your dream home and pay it off as quickly as possible, switching to principal and interest as soon as the build is done will save you significantly over the life of the loan. If you're planning to hold the property as an investment after living in it for a while, interest-only might make sense for tax reasons, but that's a conversation worth having before construction starts.
