Construction Loans: What Not to Ignore in Features

Building in Runaway Bay means understanding how construction finance works differently from a standard mortgage.

You only pay interest on funds as they're drawn down during each stage of the build, not on the full loan amount from day one. That changes how you manage cashflow, how quickly your interest costs accumulate, and which contract type makes sense for your project. If you're building near the Runaway Bay Marina precinct or on one of the canal blocks further south, knowing which features matter before you sign a building contract will save you from budget surprises six months into construction.

Progressive Drawdown: Interest Charges by Build Stage

With a construction loan, the lender releases funds in instalments as your builder completes each stage. Interest is only charged on the amount drawn down so far, not the total loan amount. During the slab stage, you might have $150,000 drawn and pay interest on that amount alone. Once frame and roof are complete and another $200,000 is released, your interest calculation adjusts to the new total.

This structure keeps early interest costs lower than a fully drawn loan, but it also means your repayments increase as construction progresses. Some borrowers assume their repayments stay flat throughout the build and find themselves short when the fourth or fifth drawdown hits. Planning for gradually increasing interest-only payments prevents that gap.

Fixed Price Contracts vs Cost Plus: What Affects Loan Approval

A fixed price building contract states the total build cost upfront and transfers cost overrun risk to the builder. A cost plus contract charges you for actual costs incurred plus a builder's margin, which means the final price can shift. Lenders prefer fixed price contracts because the loan amount is locked in at application. With cost plus arrangements, you carry the risk of budget blowouts, and most lenders either decline the application or require a larger cash buffer.

If you're working with a custom builder on a waterfront block in Runaway Bay and the design includes non-standard materials or site-specific engineering, a cost plus contract might be unavoidable. In that case, expect the lender to hold back a contingency amount or ask for proof of additional savings before approving the full loan amount.

Progress Payment Schedules: Timing Your Drawdowns

The progress payment schedule in your building contract should align with the construction draw schedule set by your lender. Most construction loans release funds across five or six stages: base stage, frame stage, lockup, fixing, and practical completion. Your builder invoices at each stage, the lender arranges a progress inspection, and funds are released once the work is verified.

Mismatches happen when a builder's payment terms don't line up with the lender's drawdown stages. If your builder expects payment at ten stages but your lender only releases at six, you'll need to cover the gap with your own funds or renegotiate the contract. Sorting this out before you commence building avoids cashflow issues once construction is underway.

Development and Council Approval: What Lenders Need Before Drawdown

You can apply for construction finance before your development application is fully approved, but the lender won't release the first drawdown until council approval is finalised and your builder is ready to start. If your Runaway Bay project requires a development application due to lot size, setbacks, or proximity to waterways, factor in council timeframes. Approval can take several months, and lenders typically require you to commence building within six months of the loan settlement date.

If council approval drags beyond that window, some lenders extend the deadline, but others treat it as a condition breach and reassess the application. Staying in contact with your broker and keeping the lender informed prevents the loan from lapsing while you wait for final sign-off.

Land and Construction Packages: Single Settlement vs Two Loans

A land and construction package rolls land purchase and build finance into one loan with a single settlement. You buy the land, the lender holds the funds for construction, and drawdowns begin once your registered builder is ready to start. This approach works well for house and land packages in estates, but if you're buying an existing block in Runaway Bay with an older dwelling that needs demolition, you might need a standard home loan for the land purchase and a separate construction loan once the site is cleared.

Some lenders offer a combined facility where the land loan converts to a construction loan after demolition, but not all do. Clarifying the structure at application stage ensures you're not stuck with two separate loans and two sets of establishment fees.

Progressive Drawing Fees and Inspection Costs

Lenders charge a fee each time they release a drawdown, typically between $150 and $400 per progress inspection. Over a five-stage build, that adds up to $750 to $2,000 in fees on top of your standard loan costs. Some lenders cap the number of inspections included in their base fee, while others charge per inspection from the first drawdown.

These fees aren't usually disclosed until you receive the loan offer, so ask your broker to confirm the total inspection cost before you commit. If you're managing a tight budget on a Runaway Bay build, an extra $1,500 in fees can affect your contingency buffer.

Interest-Only Repayments During Construction

Most construction loans default to interest-only repayments during the build, switching to principal and interest once construction is complete. That keeps your repayments lower while your funds are tied up in the project, but it also means you're not reducing the loan balance until after practical completion. If your build takes twelve months, you'll make twelve months of interest-only payments before the loan converts.

Some borrowers choose to make additional payments during construction to reduce the balance early, but this depends on whether your loan allows extra repayments without penalty. Checking the loan terms before settlement gives you the option to pay down the loan faster if your cashflow allows.

Owner Builder Finance: Why It's Harder to Access

If you're acting as an owner builder rather than using a registered builder, most mainstream lenders won't approve the loan. Owner builder projects carry higher risk from the lender's perspective because there's no licensed builder to hold accountable if the project stalls or quality issues arise. The few lenders who do offer owner builder finance typically require a larger deposit, charge a higher interest rate, and ask for evidence of construction experience or trade qualifications.

For a Runaway Bay build, unless you're a licensed builder or tradie with a strong track record, securing finance as an owner builder limits your options. Working with a registered builder opens access to a wider range of lenders and generally results in a lower interest rate.

Renovation and Spec Home Finance: Different Rules Apply

If you're renovating an existing property rather than building new, the loan structure changes. Renovation finance can be structured as a construction loan with progressive drawdowns, but some lenders treat it as a top-up on your existing home loan or a separate line of credit. The key difference is that renovation loans don't always require a registered builder if the work is minor, but larger projects involving structural changes or extensions usually do.

Spec home finance, where you build a property with the intention to sell on completion, is treated as a different product entirely. Lenders assess spec builds based on exit strategy and often require pre-sale contracts or proof of buyer interest before approving the loan. If you're building in Runaway Bay with the goal of selling to downsizers or retirees attracted to the waterfront lifestyle, the lender will want evidence that the property will sell within a reasonable timeframe.
