Beginner's Guide to Construction Loan Risks

Building a new home in Albert Park means working within heritage overlays, strict council requirements, and a market where land alone can command premium prices.

Construction finance works differently from standard home loans, and the risks are higher because you're funding a project that hasn't been completed yet. Delays, cost overruns, and builder disputes can all impact your loan, your budget, and your ability to settle. Understanding these risks before you sign a building contract gives you the chance to structure your finance properly and protect yourself if something goes wrong.

Why Construction Loans Carry More Risk Than Standard Home Loans

Construction finance involves releasing funds progressively as your build reaches specific stages, which means both you and the lender are relying on the builder completing the work on time and on budget. If the builder goes into administration halfway through, you're left with an incomplete property and a loan that's already been partially drawn down. Unlike a completed home where the asset exists from day one, a construction project is a moving target until practical completion is reached.

In our experience, Albert Park buyers underestimate how much heritage overlay requirements can delay council approval and add to costs. A renovation or knockdown rebuild in this area often requires approval from the Port Phillip Planning Department, and any variation to the original plans can trigger another round of approvals. Those delays extend the construction period, which increases the interest you pay during the build and can push you beyond the timeframe allowed in your building contract.

Fixed Price Contracts and the Risk of Variations

A fixed price building contract should lock in the total cost of your build, but variations are where that certainty falls apart. Any change you request after signing, whether it's a different tile, a moved window, or an upgraded appliance, becomes a variation that the builder can charge for outside the fixed price. These costs add up quickly, and because they're not part of the original contract, they can exceed what your lender approved.

Consider a buyer building a custom home in Albert Park who signed a fixed price contract for a two-storey home on a block near Bridport Street. The original design included standard joinery and mid-range finishes. During construction, they requested upgraded stone benchtops, additional built-in storage, and a change to the staircase design. Each variation was approved individually, but the total cost of changes reached $47,000, well beyond the contingency they'd built into their budget. The lender wouldn't increase the loan amount without a revaluation, and the revaluation came back lower than expected because the home was still incomplete. They had to cover the variation costs from savings they'd planned to use for landscaping and window furnishings.

The variation clause in your building contract determines how much the builder can charge and whether you have any ability to dispute those costs. Some contracts allow the builder to charge a percentage markup on third-party quotes, while others include a cost plus margin structure that can escalate quickly. Before you sign, make sure you understand how variations are calculated and whether the contract includes any cap on total variation costs.

What Happens if Your Builder Goes Into Administration

Builder insolvency is the most significant risk in construction finance because it leaves you with an incomplete home, a loan that's already partially drawn, and the cost of finding another builder to finish the work. When a builder goes into administration, the lender will typically freeze further drawdowns until you can demonstrate that another builder is willing to complete the project. That means you're left covering interest on the amount already drawn while also funding the cost of engaging a new builder, often at a higher rate than the original contract because they're taking on someone else's unfinished work.

In Victoria, domestic building insurance is mandatory for projects over a certain value, but it only covers specific circumstances and often doesn't pay out until you've exhausted other options. The insurance is designed to protect against incomplete work due to builder death, disappearance, or insolvency, but claims can take months to process, and the payout may not cover the full cost of completion.

How Delays Affect Your Construction Loan and Holding Costs

Most construction loans require you to commence building within a set period from the disclosure date, and any delays beyond that can trigger a loan variation or require you to reapply. Delays also extend the period during which you're paying interest on the drawn amounts without having a completed home to live in or rent out. If you're building an investment property, every extra month of construction is a month without rental income. If you're building your own home and paying rent elsewhere, it's double accommodation costs for longer than you planned.

Albert Park's proximity to the beach and heritage character means many blocks come with site-specific challenges like high water tables, contaminated soil from historical industrial use, or the need for sand pad foundations. Any of these can delay construction and increase costs beyond what the original soil test suggested. A geotechnical report is required before most lenders will approve construction finance, but even a detailed report can miss issues that only become apparent once excavation begins.

Progress Payment Schedules and the Risk of Paying Ahead of Work Completed

Construction loans release funds according to a progress payment schedule, which is typically tied to specific stages like slab down, frame up, lockup, fixing, and practical completion. The lender will arrange a progress inspection before releasing each drawdown to confirm the stage has been reached, but the inspection is often a desktop review or a brief site visit that doesn't assess the quality of the work, only whether the stage is complete.

If your builder is requesting payment in advance of work being completed, or if the progress payment schedule in your building contract doesn't align with the lender's drawdown schedule, you can end up covering the gap from your own funds. Some builders request a deposit that's higher than the first stage drawdown from the lender, which means you're funding part of the project upfront before the lender is involved.

The construction draw schedule from your lender should match the progress payments in your building contract as closely as possible. If there's a mismatch, you need to know that before you sign either document. In some cases, it's worth negotiating with the builder to adjust the payment schedule, or choosing a lender whose drawdown structure aligns with how builders in your area typically work.

Interest Costs During Construction and How Capitalisation Works

During the construction period, you'll be charged interest on the amount drawn down so far, but you won't have a completed property generating income or providing a place to live. Most construction loans offer interest-only repayment options during the build, which keeps your repayments lower while the property is incomplete. However, if you choose to capitalise the interest rather than paying it monthly, the total amount owing increases with each drawdown, and you'll be charged interest on interest by the time the build is finished.

Capitalising interest can make sense if you're managing cash flow carefully and don't want to make repayments until the property is complete, but it increases the final loan amount and reduces the equity you'll have in the property at practical completion. If the property doesn't value as highly as expected once finished, capitalised interest can leave you in a position where the loan amount exceeds the property value, particularly if the market softens during the construction period.

Council Approval Delays and the Impact on Your Build Timeline

A development application in Albert Park can take several months longer than in other suburbs due to heritage overlays, resident objections, and the need for detailed streetscape assessments. Any delay in receiving council approval pushes back your construction start date, which can affect your construction loan approval if the lender's offer has an expiry date or requires you to commence within a certain period.

If you're purchasing land with the intention to build, some lenders will allow you to settle on the land using a land and construction package, where the land purchase and the construction loan are approved together but drawn separately. This avoids the need to reapply for finance once the land settles, but it also means you're committed to building within the timeframe the lender specifies, even if council approval takes longer than expected.

We regularly see buyers in Port Phillip who assume a straightforward knockdown rebuild will sail through council, only to face months of delays due to overlooked heritage considerations or neighbour disputes. If your building contract includes a sunset clause or a timeframe within which construction must commence, a council delay can put you in breach of that contract or force you to renegotiate terms with the builder at additional cost.

Protecting Yourself Before You Commit to Construction Finance

Before you sign a building contract or submit a construction loan application, make sure you've factored in a contingency of at least 10% to 15% of the total build cost. That contingency should cover variations, delays, and any cost increases that arise during construction. If your budget doesn't include a buffer, you're assuming the build will go exactly to plan, which is rarely the case.

Choose a registered builder with a solid track record and verified references, not just the lowest quote. A builder who has completed projects in Albert Park or surrounding suburbs will understand the local council requirements and the site conditions common to the area. Check their Builder Registration through the Victorian Building Authority and confirm that domestic building insurance is in place before you hand over any deposit.

Structure your construction finance with a lender who understands how building projects work and offers flexibility if delays occur. Not all lenders handle construction loans the same way, and some are far more rigid when it comes to variations, extensions, or builder changes. Working with a mortgage broker in Albert Park who has experience with construction loans means you're more likely to secure a loan structure that protects you if the project doesn't go to plan.

If you're considering a renovation rather than a new build, the same risks apply, but the finance structure may differ depending on whether you're living in the property during the works. A house renovation loan can be structured as a construction loan with progressive drawdowns, or as a lump sum if the scope of works is smaller and the builder doesn't require stage payments.

Construction finance gives you the opportunity to create exactly the home you want, but it requires careful planning and a realistic understanding of what can go wrong. The risks are manageable if you structure your loan properly, choose your builder carefully, and build in a buffer for the unexpected.
