Beginner's Guide to Progressive Drawdown

A progressive drawdown means your lender releases the loan amount in instalments as your build reaches specific milestones.

Most people picture a home loan as a single lump sum that hits your account on settlement day. When you're building from scratch, the process works differently. Your lender releases funds to your registered builder in stages, matching the construction schedule. You only pay interest on the amount drawn down so far, not the full loan amount. That structure keeps your repayments lower during the build, but it also means you need to understand when each payment happens, what triggers it, and how the schedule fits your contract.

How the Drawdown Schedule Lines Up With Your Build

Your lender creates a progress payment schedule that matches the stages in your fixed price building contract. Typical stages include base, frame, lock-up, fixing, and practical completion. Each stage triggers a payment once the lender's valuer confirms the work is finished to the required standard. The valuer conducts a progress inspection, checks the quality of construction against council plans and the development application, then authorises the next instalment. Your builder requests payment through your broker or directly with the lender, and funds usually arrive within a few business days after approval.

Consider a couple building a custom design home on suitable land in regional Victoria. Their fixed price contract sets out five payment stages. At the base stage, the valuer inspects the slab and confirms the footings meet the council approval conditions. The lender releases the first instalment, around 15% of the total building loan. The couple pays interest only on that 15%, not the full loan amount. By lock-up, they've drawn down roughly 60% of the loan, and their interest-only repayments have climbed accordingly. At practical completion, the final payment goes through, and they transition to standard home loan repayments on the full balance.

What Happens When You're Building on Land You Already Own

If you already own the land outright, the lender treats it as equity in the project. The loan covers the construction cost only, and your first drawdown pays the builder's deposit. If you're still paying off the land, you'll usually roll that existing loan into a land and construction package. The new facility pays out your land loan at settlement, then switches to progressive drawdown mode for the build. Either way, you're paying interest on whatever portion of the loan has been released, plus any remaining balance from the land component.

Interest Costs During Construction

You only pay interest on the funds drawn down at each stage. If your total loan amount is $500,000 and you've drawn $200,000 by lock-up, your interest charges apply to that $200,000. Most lenders offer interest-only repayment options during construction, so you're not making principal payments until the build finishes. That keeps your monthly outgoings lower while you're still covering rent or a mortgage elsewhere. Once you reach practical completion and the loan converts to a standard home loan, you start making principal and interest repayments on the full balance, or you can stay on interest-only if your lender allows and it suits your circumstances.

Some lenders charge a progressive drawing fee each time they conduct a progress inspection and release funds. The fee typically sits between $200 and $400 per drawdown, and it covers the valuer's site visit. Factor that cost into your budget alongside other construction funding expenses like council fees and connection charges for plumbers and electricians.

How Long You Have to Start the Build

Most construction loan approvals require you to commence building within a set period from the disclosure date, often six to twelve months. If your builder experiences delays with council plans or the development application takes longer than expected, you may need an extension. Lenders usually grant one if you can show the delay is outside your control and you're still committed to the project. If the approval lapses, you'll need to reapply, and the construction loan interest rate may have changed in the meantime.

Owner Builder and Cost Plus Contracts

If you're taking on owner builder finance, the lender will want detailed costings for each trade and a breakdown of when you'll pay sub-contractors. Instead of a progress payment schedule tied to a builder's contract, you'll submit invoices as you complete each stage. The lender releases funds based on those invoices and the progress inspection results. It's more hands-on, and you carry more responsibility for managing cash flow and coordinating trades.

A cost plus contract works similarly but involves a registered builder who charges for labour and materials as they go, plus a margin. The loan structure still uses progressive drawdown, but the payment amounts aren't locked in from the start. You'll need a buffer in your loan amount or savings to cover any variations, and the lender will cap the total facility based on the valuation and your borrowing capacity.

What This Means for Renovations and Knockdown Rebuilds

If you're renovating an existing home rather than building new, you can still access construction loan options from banks and lenders across Australia. The drawdown schedule will reflect the stages in your renovation contract, whether that's demolition, structural work, or internal fit-out. For a knockdown rebuild, the lender treats it as new home construction finance once the old house is removed. You'll need council approval for the demolition, and the first drawdown usually covers that cost plus the new slab.

Switching From Construction Mode to Your Permanent Loan

Once you reach practical completion and move in, your construction to permanent loan rolls into standard repayments. The lender conducts a final valuation to confirm the property is finished and meets the approved plans. At that point, your interest rate may shift if you've been on a separate construction loan interest rate during the build. Some lenders use the same rate throughout, while others apply a higher rate during construction and switch you to a standard variable or fixed rate afterwards. Confirm that detail when you lodge your construction loan application so there are no surprises at the end.

Your broker will help you structure the transition so you're ready to make principal and interest repayments from day one, or they can set up an ongoing interest-only period if that suits your financial position and the lender agrees.
