Simple hacks to fund your build with progressive drawdown

Progressive drawdown means your lender releases your loan in stages as your build reaches defined milestones, not in a single upfront payment.

You only pay interest on the amount drawn down so far, which keeps your repayments lower during construction. Once the build completes, the loan typically converts to a standard home loan with principal and interest repayments. Most lenders tie each drawdown to a progress inspection, so funds are released only after a quantity surveyor or bank valuer confirms the work is complete. The schedule, fees, and inspection process vary between lenders, and matching the right structure to your builder's payment schedule can save you thousands in holding costs.

How progressive drawdown releases funds during your build

Your lender divides the total loan amount into stages that align with your building contract. A typical schedule includes five or six drawdowns: deposit or base stage, frame stage, lock-up stage, fixing stage, and completion. Each stage is defined by specific construction milestones, and your builder submits a claim once that milestone is reached. The lender arranges a progress inspection, and if the work is verified, the funds are released directly to the builder.

Consider a couple building a knock-down rebuild in Highett. Their builder's contract lists five progress payments. The lender's drawdown schedule matches those payments, with inspections scheduled within five business days of each claim. The builder waits for cleared funds before starting the next stage, so any delay in inspection or approval can push out the build timeline. Knowing the lender's inspection turnaround before you sign the building contract helps you avoid disputes over delayed payments.

What you'll pay in fees and interest during construction

Most lenders charge a progressive drawing fee for each inspection and drawdown, typically between $200 and $400 per stage. Over a five-stage build, that's $1,000 to $2,000 in fees before you've made a single repayment. During construction, you make interest-only repayments on the amount drawn down so far. If your lender has released half your loan amount, you're only paying interest on that half. The interest rate during construction is usually the same as the rate that applies once the loan converts to principal and interest.

Some lenders cap the number of drawdowns included in the approval, so if your builder requires seven stages but your loan only covers five, you'll pay extra fees for the additional inspections. If you're working with a custom builder or managing the project yourself as an owner builder, the number of drawdowns can climb quickly as you pay subcontractors directly. Choosing a lender that allows flexibility in the drawdown schedule without punitive fees becomes particularly important in those scenarios.

How council approval and building timelines affect your loan

Most construction loan approvals require you to commence building within a set period from the disclosure date, usually six to twelve months. If your council approval is delayed or your builder pushes the start date, you may need to reapply or extend your approval, which can mean re-assessing your financial position and potentially facing a different interest rate. In Highett, development applications for knock-down rebuilds or significant extensions can take several months, particularly if the design requires variations to the local planning scheme or if neighbours lodge objections.

If you're buying a house and land package or building on land you already own, confirm your builder's estimated start date and cross-check it against your loan's commencement deadline. Some lenders offer longer validity periods, which gives you breathing room if approvals take longer than expected. If you're considering a construction loan in Highett, flagging any known delays with your broker early means they can structure the approval to match your actual timeline rather than a generic one.

Fixed price contracts versus cost plus arrangements

A fixed price building contract sets a total contract sum, and your lender bases the loan amount on that figure plus any additional costs like landscaping or fencing. The builder absorbs any cost overruns, so your drawdown schedule remains predictable. A cost plus contract means you pay the builder's costs as they're incurred, plus an agreed margin. Your final build cost isn't locked in, which makes it harder for lenders to assess the loan amount and increases the risk that you'll need additional funds partway through the build.

Most lenders prefer fixed price contracts because the loan amount is defined upfront. If you're working with a builder who operates on cost plus, you'll need a larger contingency buffer, and some lenders may reduce the loan-to-value ratio they're willing to offer. In our experience, borrowers who proceed with cost plus arrangements without a clear understanding of how overruns are funded often find themselves scrambling for bridging finance or personal loans once the build exceeds the original estimate. If a cost plus contract is the only option, ask your broker which lenders will still approve construction finance on that basis and what conditions apply.

When the loan converts to principal and interest repayments

Once your build reaches practical completion and the final inspection is approved, the lender converts your loan from interest-only construction funding to a standard home loan. At that point, you begin making principal and interest repayments based on the loan term you selected at approval. The interest rate may change if you were on a variable rate during construction and rates have moved, or if you're switching from a construction-specific rate to a different product.

Some lenders offer a construction to permanent loan, which means the entire process is handled under one approval with no need to refinance after completion. Others require you to discharge the construction facility and take out a new home loan, which involves additional legal costs and settlement fees. If you've built in Highett and property values have risen during construction, you may have more equity at completion than you started with, which can improve your rate or allow you to drop lender's mortgage insurance if you were previously below 80% loan-to-value. Discussing the end structure during the initial loan application means you're not surprised by costs or rate changes once the build is finished.
