Simple hacks to reduce construction loan fees

The fee structure that catches most dentists off guard

Construction finance involves a different fee model than standard home loans. Instead of a single settlement with one set of upfront costs, you pay fees at multiple points as the build progresses, including a Progressive Drawing Fee each time funds are released to your builder, valuation or inspection charges to confirm work is complete, and potentially variation fees if your design changes mid-build.

Consider a general dentist building a custom home with a $680,000 construction loan. The lender releases funds across five progress payments tied to foundation, frame, lock-up, fixing, and completion stages. At each drawdown, the lender charges a Progressive Drawing Fee, typically between $150 and $400 per inspection depending on the institution. Across five payments, that adds $750 to $2,000 in fees that don't appear on a standard loan product. Add in the initial valuation of your land and building contract at around $300 to $600, and the final valuation at practical completion for another $300 to $600, and you're carrying $1,350 to $3,200 in assessment costs before the first brick is laid.

The loan amount you're approved for covers the build, but these progressive fees usually come out of your own funds unless you specifically negotiate them into the facility. That means if you've allocated every dollar of your savings to deposit and settlement, you'll need an additional buffer just to move the money from lender to builder.

How the progressive drawdown model changes your cash flow

With construction finance, you only pay interest on the amount the lender has advanced so far, not the full approved loan amount. During the build, you make interest-only repayments on whatever has been drawn down, which keeps your repayments lower in the early months compared to a fully drawn loan. Once construction finishes and the loan converts to a standard home loan, you begin principal and interest repayments on the total amount.

In the scenario above, after the foundation stage drawdown of around $136,000, your monthly interest cost at current variable rates would be roughly a quarter of what it would be once the full $680,000 is advanced. That gives you breathing room during the build, but it also means your cash flow shifts sharply once you move in and the loan converts. Planning for that jump matters, particularly if you're also managing practice expenses or locum costs while the build is underway.

Fixed price building contracts and why they affect your approval

Most lenders require a fixed price building contract before they'll approve construction funding. The contract must specify a total build cost, a defined scope of work, and a progress payment schedule that aligns with construction milestones. Without a fixed price agreement, the lender has no certainty about the final loan amount, and most won't proceed.

A cost plus contract, where you pay the builder's actual costs plus a margin, introduces too much variability for standard construction finance. If you're working with a custom builder who prefers cost plus terms, expect to either negotiate a fixed price variation or seek a specialist lender who can accommodate that structure. Specialist lenders typically charge higher interest rates or establishment fees to offset the additional risk, so the trade-off needs to be deliberate.

Your building contract should also specify when you must commence building within a set period from the disclosure date, usually within six months. If your council approval or site preparation drags beyond that window, some lenders will require a contract extension or a new valuation, triggering another round of fees. Keeping your development application and council plans moving quickly reduces the chance of paying twice for the same assessment.

The variation fee you didn't budget for

Once construction starts, any change to the original scope requires formal approval from your lender. Upgrading fixtures, extending a room, or adding a pool mid-build means submitting revised plans and a new contract price. Lenders typically charge a variation fee between $200 and $500 to reassess the security value and confirm the additional cost is covered by your loan facility.

Some variation fees are unavoidable if you discover a site issue that requires remediation, such as unexpected rock or poor soil conditions. Others come from design changes that could have been locked in earlier. The cost of the variation fee itself is modest, but the delay while the lender reviews and approves the change can hold up progress payments and push out your completion timeline, which in turn extends the period you're paying double accommodation costs if you're renting while building.

Progress inspection costs and who pays them

Each time your builder requests a drawdown, the lender arranges a progress inspection to confirm the work matches the stage being claimed. The inspection is usually carried out by a valuer or quantity surveyor who visits the site, photographs the progress, and provides a report to the lender confirming the stage is complete and the amount being claimed is reasonable.

The Progressive Drawing Fee covers the lender's administration, but the inspection itself is often billed separately, either as part of that fee or as a standalone cost depending on the lender's structure. If you're building in a regional area or on a remote block, some lenders add a travel surcharge for the inspector, particularly if the site is more than an hour from a major centre. That can add another $100 to $200 per inspection, turning a five-stage build into an extra $500 to $1,000 in fees you might not have anticipated.

Owner builder finance and the fee premium

If you're acting as an owner builder rather than engaging a registered builder, expect a different fee structure and typically a higher interest rate. Lenders view owner builder projects as higher risk because there's no licensed contractor guaranteeing the work, and progress inspections become more detailed and more frequent to protect the lender's security.

Some lenders won't offer owner builder finance at all. Those that do often require more frequent drawdowns tied to specific trades rather than broad construction stages, meaning you might have eight or ten inspections instead of five. At $300 per inspection, that's an additional $900 to $1,500 in progress fees compared to a standard build. You'll also likely need a higher deposit, often 20% to 30% instead of the 10% to 15% typical for a build with a registered builder, which changes your upfront cash requirement significantly.

How land and construction packages simplify the fee structure

A land and construction package from a volume builder often includes a single contract covering both the land purchase and the build, with a streamlined approval process and fewer separate fees. Because the builder has an established relationship with certain lenders, the package may come with reduced or waived Progressive Drawing Fees, or a simplified drawdown schedule with fewer inspection points.

The trade-off is less flexibility in design. Volume builders work from a set range of plans with limited customisation, so if you want a fully custom layout or specific materials, you'll need to move away from the package model and back into the higher-fee territory of bespoke construction finance. For dentists who want to build but prefer predictability over personalisation, the package route can reduce both upfront fees and approval complexity. If you're also considering a house and land package, the same fee benefits often apply.

Renovation finance and when construction loan fees apply

If you're undertaking a major renovation rather than a new build, the same construction finance structure applies once the project exceeds a certain threshold, typically around $100,000 to $150,000 depending on the lender. Below that amount, you might access funds through a standard home equity facility or home loan refinancing without triggering the progressive drawdown model.

Once the renovation moves into construction finance, you're subject to the same Progressive Drawing Fees, inspection costs, and contract requirements as a new build. The difference is that you're living in the property while work is underway, which can complicate inspections if certain areas remain occupied. Some lenders charge an additional fee if the inspection requires multiple visits to assess different stages of a staged renovation, particularly if you're keeping parts of the home liveable while others are stripped back to framework.

Pre-approval and how it locks in your fee schedule

Securing loan pre-approval before you finalise your building contract gives you certainty around both the interest rate structure and the fee schedule. Lenders provide a breakdown of all construction-related fees in the pre-approval documentation, so you know exactly what you'll pay at each drawdown and at practical completion.

Pre-approval also lets you negotiate with builders from a position of certainty. If your lender requires progress payments at five stages and your builder's standard contract specifies six, you can ask the builder to align with the lender's schedule before signing, avoiding the risk of paying for an extra inspection. Some builders will adjust their payment terms to match your lender's requirements if you raise it early, but once the contract is signed, any change becomes a variation and triggers the associated fee.

If your financial structure involves self-employed income or you're consolidating existing debts while building, your pre-approval needs to account for those elements upfront so the fee schedule reflects the full complexity of your application, not just the construction component.

Building a home or managing a significant renovation involves more moving parts than purchasing an established property, and the fee structure reflects that complexity. Budgeting for progressive drawing fees, inspection costs, and potential variation charges from the outset means you're not scrambling for extra funds mid-build.
