Do you know how construction loans work for investors?

Construction Loans Release Funds as Your Build Progresses

Construction finance works differently to a standard mortgage because the lender releases funds in stages rather than as a lump sum. You draw down money progressively as the builder completes specific milestones, which means you only pay interest on the amount drawn at each stage. For someone building an investment property in Hawthorne, this structure directly affects your holding costs during construction and your ability to manage cashflow across multiple projects.

Most lenders release funds across five or six progress payments tied to construction milestones like slab down, frame up, lock-up, and practical completion. The builder invoices at each stage, a bank-appointed valuer inspects the work, and the lender releases the next payment. During construction, you typically make interest-only repayments on whatever has been drawn down so far, not the full loan amount.

Fixed Price Building Contracts Are Usually Required

Lenders generally require a fixed price building contract with a registered builder before they approve construction finance. This protects both you and the lender from cost overruns and ensures the project has a defined budget. Owner builder finance exists but comes with stricter criteria and higher deposit requirements, and most lenders treat it as a different product altogether.

Consider an investor planning to build a dual-occupancy development on a site near Lourdes Hill College. The lender will want to see council approval, a fixed price contract with a Queensland-licensed builder, and evidence that the land settlement and construction budget fit within your borrowing capacity. If the total project cost is outside what you can service, the application won't proceed regardless of how much equity you hold elsewhere.

The Progressive Drawing Fee Adds to Your Upfront Costs

Each time the lender releases a progress payment, most banks charge a progressive drawing fee, typically between $300 and $500 per drawdown. Over five or six payments, this adds up to around $2,000 to $3,000 in fees that don't apply to a standard home loan. Some lenders cap the total fee or charge a flat rate for the entire construction period, so it's worth comparing how different lenders structure this cost.

These fees are separate from the valuation cost at each stage, which the lender also passes on. For an investment property in Hawthorne, where you're likely managing other holding costs like rates and land tax, these incremental fees need to be factored into your project budget from the outset.

Interest During Construction Is Calculated on Drawn Amounts Only

You only pay interest on the funds that have been released, not the total approved loan amount. If your construction loan is approved for $800,000 but only $200,000 has been drawn for the slab and frame stages, your interest repayments are calculated on $200,000. This keeps your repayments lower during the build, but it also means your cashflow changes every time a new progress payment is made.

For investors, this creates a moving target when calculating serviceability. Lenders assess your ability to service the full loan amount at completion, not just the initial drawdown. If you're holding other investment debt or planning to retain the property long-term, your income needs to support the entire loan once construction finishes and the loan converts to principal and interest or remains interest-only under standard investment loan terms.

Land and Construction Packages Combine Two Settlements

A land and construction package involves two separate transactions: purchasing the land and funding the build. You settle on the land first, then the construction loan activates once contracts are signed and council approval is in place. Some lenders offer a single approval that covers both components, while others assess them separately.

In Hawthorne, where vacant land is limited and most opportunities involve knockdown-rebuild or subdivision, the land component is often settled months before construction begins. During that period, you're paying interest on the land loan without any rental income, so timing the build commencement becomes a cashflow consideration. Most lenders require you to start construction within a set period from the loan settlement, usually six to twelve months, or the approval may lapse.

Your Borrowing Capacity Is Assessed on the Completed Value

Lenders assess construction loans based on the projected value of the finished property, not just the build cost. This is different to a standard purchase where the property already exists and can be valued immediately. The lender will order a valuation that estimates the 'as if complete' value, and your loan-to-value ratio is calculated against that figure.

If the completed valuation comes in lower than expected, you may need to increase your deposit or reduce the loan amount. In a scenario where an investor is building a new duplex in Hawthorne with a projected end value that the valuer doesn't support, the lender may only approve a lower loan amount, leaving a funding gap that needs to be covered from other sources. This is one reason construction projects sometimes stall even after council approval is granted.

Construction to Permanent Loans Convert Automatically

Most construction loans automatically convert to a standard mortgage once the build is complete and the final progress payment is made. This is called a construction to permanent loan, and it means you don't need to reapply or go through a second settlement process. The loan simply rolls over from the progressive drawdown phase into a standard home loan or investment loan with principal and interest or interest-only repayments.

Some lenders allow you to lock in a fixed rate for the end loan while you're still in the construction phase, while others keep you on a variable rate throughout. If you're building an investment property and plan to refinance after completion to access equity or consolidate debt, you'll want to understand whether break costs apply if you refinance before a certain period.

Hawthorne's Character Housing Limits New Build Opportunities

Hawthorne is dominated by pre-war Queenslanders and post-war character homes, with relatively few vacant blocks or subdivision opportunities compared to neighbouring suburbs like Morningside or Cannon Hill. Most construction projects in the area involve knockdown-rebuild or significant renovations that require development approval from Brisbane City Council. The proximity to the Brisbane River and flood mapping also affects what can be built and how lenders assess risk.

If you're planning a knockdown-rebuild near Hawthorne Park or along Riding Road, the lender will want to see that the new dwelling complies with council requirements and that flood risk has been factored into the valuation. Some lenders apply stricter lending criteria or lower loan-to-value ratios for properties in flood-affected zones, even if the new build is designed to current standards.

Development Applications and Council Approval Are Lending Conditions

You can't draw down construction funds until council approval is finalised. Lenders treat development approval as a condition of finance, and the loan offer will specify that construction cannot commence until all council and building certifier requirements are met. If your DA is still under assessment or subject to appeal, the lender won't release any funds.

This is relevant in Hawthorne where character overlays and neighbourhood planning rules can slow down approvals or require design changes. An investor who assumes approval is automatic may find themselves holding land for longer than expected, paying interest without the ability to start building. Working with a mortgage broker who understands the DA process and how it affects loan timing can help you structure finance that aligns with your approval timeline.
