Unlock the secrets to construction loan structures

Construction loan structures determine how your lender releases funds during the build and what contract arrangements protect both you and your builder.

Building in Ringwood means working with a construction finance structure that matches your project type, whether that's a knockdown-rebuild near the Eastland precinct, a dual occupancy development closer to Mullum Mullum Creek, or a custom design on one of the larger blocks backing onto the Maroondah Highway corridor. The structure you choose affects your repayment obligations during construction, the timing of fund releases, and how much control you retain over the build process.

How Progressive Drawdown Works in Construction Finance

Progressive drawdown means your lender releases funds in stages as the build reaches specific milestones, and you only pay interest on the amount drawn down so far. Most lenders structure drawdowns around five or six stages: base or slab, frame, lockup, fixing, practical completion, and final completion. Each stage requires a progress inspection by a representative appointed by the lender to confirm the work matches the claim.

Consider a buyer demolishing an older weatherboard on a 700-square-metre block near Ringwood North and replacing it with a two-storey brick veneer home under a fixed price building contract. The loan amount might cover land value plus construction costs. At the base stage, the lender releases around 15 to 20 per cent of the construction portion after their inspector confirms footings and slab are complete. The borrower pays interest only on that drawn amount during the construction period, not on the full loan. By lockup stage, roughly 50 to 60 per cent of construction funds have been released, with the remainder following through fixing and completion stages.

Lenders typically charge a Progressive Drawing Fee each time they conduct an inspection and release funds. This fee usually sits between $150 and $400 per drawdown, depending on the lender and whether the inspection is conducted by an external valuer or an in-house representative. Some lenders cap the number of drawdowns included in the loan structure, which matters if your builder requests variations or your project splits stages differently.

Fixed Price Contracts vs Cost Plus Contracts

A fixed price building contract sets a total construction price at the outset, with variations charged separately. A cost plus contract charges you the actual cost of labour and materials plus a builder's margin, usually between 10 and 20 per cent.

Fixed price contracts suit most owner-occupier builds because they lock in the construction budget and align cleanly with lender drawdown schedules. The builder submits a progress claim at each stage, the lender inspects, and the funds release according to a predetermined percentage of the contract price. Most lenders structure construction loans around fixed price contracts because the total exposure is known upfront.

Cost plus contracts offer more flexibility for custom builds where design changes are likely or material selections haven't been finalised. However, fewer lenders approve cost plus structures because the final loan amount remains uncertain until the build completes. When a lender does approve cost plus, they typically require detailed costings from the builder, council-approved plans, and a larger buffer in the loan amount to cover variations. The borrower assumes more risk if costs run over, which is why owner builder finance or projects involving unregistered builders almost always require cost plus arrangements and attract stricter lending criteria.

Construction to Permanent Loan Structures

A construction to permanent loan transitions automatically from interest-only repayments during the build to principal and interest repayments once construction completes. You submit one loan application covering both the construction phase and the ongoing home loan, which means one approval process, one set of application fees, and one settlement.

This structure suits borrowers building their primary residence in Ringwood who plan to live in the property long term. During construction, you make interest-only repayments on the drawn balance. Once practical completion is certified and the lender conducts a final valuation, the loan converts to a standard variable or fixed rate home loan with principal and interest repayments based on the full loan amount. The construction loan interest rate during the build is often slightly higher than the ongoing rate, but the difference typically sits within 0.20 to 0.50 percentage points depending on the lender.

Some lenders offer interest-only repayment options for a set period after construction completes, which can help if you're selling another property or managing cash flow during the move. Others convert immediately to principal and interest. Confirming the post-construction repayment structure during the loan application avoids surprises when the build finishes.

Land and Construction Package Structures

A land and construction package finances both the land purchase and the build under a single loan facility. The lender settles the land purchase first, then holds the construction portion in reserve and releases it progressively as the build advances.

This structure works when you're buying vacant land in areas like Ringwood East or near Bedford Road and engaging a registered builder under a fixed price building contract. The lender values the land at purchase, then revalues the combined land and proposed dwelling to determine the total loan amount. You must commence building within a set period from the land settlement, usually 6 to 12 months depending on the lender. Missing that window can trigger a loan review or require a new valuation.

During the period between land settlement and construction commencement, you pay interest on the land portion only. Once construction starts and the first drawdown occurs, interest accrues on both the land and the drawn construction amount. Most lenders require council approval and a signed building contract before they'll settle the land purchase, which means your development application and builder selection need to be finalised before you can proceed.

Progress Payment Schedules and Builder Claims

The progress payment schedule in your building contract should align with your lender's drawdown structure. Misalignment creates cash flow pressure if your builder expects payment before your lender releases funds.

Most registered builders working on fixed price contracts structure their progress claims to match standard lender drawdown stages. The builder invoices after completing each stage, the lender inspects within a few business days, and funds release directly to the builder's account or to you for payment. Some lenders pay builders directly, others release funds to the borrower who then pays the builder. Direct payment reduces the risk of funds being diverted, but it also removes your ability to withhold payment if there's a dispute over the quality of work.

If your builder uses a non-standard progress payment schedule, for example splitting the frame stage into two separate claims or requesting a deposit beyond the initial 5 per cent, you'll need to confirm your lender can accommodate that structure. Lenders sometimes approve additional drawdowns but will charge the Progressive Drawing Fee for each inspection. Alternatively, you may need to negotiate the builder's schedule to match the lender's standard stages.

Renovation Finance Structures

Renovation finance works like construction finance but applies to substantial alterations or extensions on an existing dwelling. The lender values the property in its current state, assesses the proposed works, and determines the end value based on the completed renovation.

A house renovation loan typically involves fewer drawdown stages than new construction, often three or four depending on the scope. For a significant renovation in Ringwood, such as adding a second storey or extending a single-fronted cottage near the train station, the lender might structure drawdowns around demolition and preparation, structural works, internal fit-out, and completion. The same principles apply: you only pay interest on drawn amounts, the lender inspects before each release, and you need council approval and a contract with a registered builder.

Renovation finance becomes more complicated when you're living in the property during works because lenders assess whether the dwelling remains habitable and whether the renovation affects the property's insurance coverage. Some lenders exclude owner-occupied renovations if the works make the property unliveable for more than a set period, usually three months.

Owner Builder and Spec Home Structures

Owner builder finance and spec home finance involve higher risk for lenders, so they apply stricter criteria and often require larger deposits. If you're acting as an owner builder, most lenders require evidence of relevant building experience, detailed cost breakdowns for materials and subcontractors, and a larger equity buffer, often 20 to 30 per cent.

Spec home finance applies when you're building a property to sell rather than occupy. Lenders treat this as an investment activity and price the loan accordingly. The construction loan interest rate for spec builds is usually higher than for owner-occupied builds, and lenders require evidence that you can service the loan even if the property doesn't sell immediately after completion. Some lenders won't approve spec builds at all unless you're an established developer with a track record.

Both structures require more documentation during the loan application and more frequent communication with the lender during construction. If you're engaging subcontractors directly as an owner builder, the lender may inspect more frequently or require statutory declarations confirming that plumbers, electricians, and other trades have been paid before releasing subsequent drawdowns.

What Happens If the Build Goes Over Budget

If your construction costs exceed the approved loan amount, you'll need to cover the shortfall from your own funds or apply for a loan variation. Lenders don't automatically increase the loan if your builder submits a variation claim or if unexpected site conditions add costs.

Before approving a variation, the lender reassesses your borrowing capacity based on the higher loan amount and may require an updated valuation to confirm the property's end value still supports the increased lending. This process can take several weeks, which delays progress payments and potentially halts construction. Planning a buffer into your initial loan application, usually 5 to 10 per cent of the construction budget, reduces the likelihood of needing a mid-build variation.

If the build runs significantly over budget and you can't secure additional funding, you may need to negotiate a reduced scope with the builder or sell the partially completed property to exit the loan. Both outcomes carry financial consequences, which is why accurate costings and a registered builder working under a fixed price building contract provide the most protection.

Building in Ringwood or surrounding suburbs means understanding which construction finance structure aligns with your project type, contract arrangement, and repayment capacity during the build. The right structure depends on whether you're buying land, renovating, building as an owner-occupier, or developing as an investment.
