Beginner's Guide to Construction Investment Loans

What Makes Construction Finance Different for Investment Properties

Construction finance for investment property works through progressive drawdowns instead of a single lump sum. Your lender releases funds in instalments as each stage of the build completes, and you only pay interest on the amount drawn down at each stage, not the full loan amount.

This structure affects how you manage cash flow during the build. If you're constructing a two-storey townhouse in Brighton to hold as a rental, you might wait three months between the slab pour and frame inspection before the next drawdown releases. During that period, you're paying interest only on what's been drawn so far, which keeps holding costs lower than if you'd borrowed the full amount upfront. Most lenders charge a Progressive Drawing Fee of around $200 to $400 per inspection, and a quantity surveyor or bank-appointed inspector needs to verify each stage before funds release.

The construction loan approval process also requires council-approved plans and a fixed price building contract with a registered builder before any formal offer issues. If you're planning to build on land you already own in Brighton, the lender will value both the land and the proposed dwelling, then lend against the combined end value, not just the dirt.

How the Progressive Payment Schedule Works

Lenders typically release funds across five or six stages, starting with a deposit to the builder and ending with final completion. The exact schedule depends on your building contract, but a common structure includes base stage, frame stage, lock-up stage, fixing stage, and practical completion.

Consider an investor building a dual-occupancy development on a subdivided block near Were Street. The land cost $1.2 million, and the build contract sits at $800,000. The lender approves an 80% loan-to-value ratio against the end value of $2.4 million, which gives a loan amount of $1.92 million. The first drawdown covers the land purchase if it hasn't settled yet, or if the land is already owned, the first stage payment to the builder after the slab goes down. Each subsequent drawdown aligns with the progress payment schedule in the building contract. The builder invoices for each stage, the lender's inspector confirms the work, and funds release within a few days.

Between drawdowns, the investor pays interest only on what's been drawn. After the frame stage, if $900,000 has been released, interest applies to that amount, not the full $1.92 million. This keeps holding costs lower during the build, though you'll also need to cover any interest on the land loan if it was purchased separately.

Loan Structure Options During and After Construction

Most construction facilities convert to a standard investment loan once the build reaches practical completion. During construction, repayments are interest-only on the drawn amount. After completion, you can choose to continue on interest-only repayment options or switch to principal and interest, depending on your tax strategy and cash flow.

Some lenders offer a construction to permanent loan, which means the construction facility automatically rolls into a standard variable or fixed rate loan without needing to reapply. Others require a separate application once the build finishes, which can add time and another round of documentation. If you're holding the property long-term as a rental, locking in the end loan structure upfront removes uncertainty and avoids a second approval process mid-project.

Interest rate during construction is usually variable, even if you plan to fix the rate post-completion. A few lenders let you fix the rate on the full loan amount from the start, but you'll pay interest on the entire sum from day one, which eliminates the cash flow benefit of progressive drawdowns. For most investors, variable during construction and the option to fix after makes more sense.

What Lenders Look for in a Construction Loan Application

Lenders assess both the project and the borrower. They want to see council approval, a fixed price building contract with a registered builder, and evidence that the build will commence within a set period from the Disclosure Date, usually three to six months. If you're using a cost plus contract instead of a fixed price building contract, fewer lenders will participate, and those that do typically apply stricter conditions or lower loan-to-value ratios.

Your borrowing capacity gets tested against the projected rental income once the property completes, not just your current income. If the development application shows two dwellings and comparable properties in Brighton rent for $650 per week each, the lender will factor in $67,600 annual rental income when calculating serviceability. They'll also stress-test that income and your existing commitments at a higher interest rate, usually 3% above the actual rate, to confirm you can service the debt if rates rise.

Lenders also want to see a clear exit for the construction facility. If you're building to hold, they need confidence that the end loan will service from rental income and your other income sources. If you're building to sell, they may require pre-sale contracts or evidence of buyer demand in the area before approving the facility.

Owner Builder Finance and When It Applies

Owner builder finance is harder to access and comes with higher rates and lower loan-to-value ratios. Most mainstream lenders won't touch owner builder projects unless you're a registered builder yourself. Specialist lenders will consider it, but expect to borrow no more than 60% to 70% of the end value, compared to 80% or more with a registered builder.

If you're coordinating trades yourself to save on builder's margin, you'll need a larger deposit and enough cash flow to cover the gap between what the lender releases and what the plumbers, electricians, and other sub-contractors invoice. The progressive drawdown process also becomes more involved because the lender needs detailed invoices and proof of payment before each release, rather than relying on a head contract with a registered builder.

For most investors in Brighton, the cost saving from owner building doesn't justify the restricted finance options and the time required to manage the build. A fixed price contract with a registered builder opens up more lenders, higher loan-to-value ratios, and fewer headaches during the approval and construction process.

Timing the Build and Holding Costs

Construction timelines in Brighton can stretch due to council approval delays, builder availability, and weather. A typical build might take nine to twelve months from slab to practical completion, but that doesn't include the time before construction starts. From the date your development application goes in to the date the frame goes up, you could be looking at six months or more.

Holding costs during that period include interest on any land loan, council rates, and insurance. If you've bought a house and land package, the land settles before construction starts, so you're paying interest on the land from settlement day. If you're building on land you already own, those holding costs start from the date you take out the construction facility or any interim land loan.

Once construction starts, interest on the drawn amounts becomes the main holding cost. If your loan amount is $1.5 million and $600,000 has been drawn by the lock-up stage, you're paying interest on $600,000, not the full amount. At current variable rates, that might run around $2,500 to $3,000 per month, depending on the lender and your rate. That cost increases with each drawdown until the full loan is drawn at practical completion.

Rental Income and Serviceability After Completion

Once the build finishes and tenants move in, rental income helps service the loan. Lenders typically assess rental income at 80% of the market rent to account for vacancy and management costs. If your new townhouse in Brighton rents for $750 per week, the lender will use $600 per week, or $31,200 annually, when calculating serviceability.

If you're holding multiple investment properties, the combined rental income and your personal income need to service all debts, including the new construction loan. Some investors find that the rental income alone doesn't fully cover the loan repayments, especially if they've borrowed at a high loan-to-value ratio. The shortfall comes out of personal income, which is fine as long as serviceability stacks up and you've planned for the cash flow gap.

Interest-only repayments keep the monthly outlay lower, which helps with cash flow if you're building a portfolio. Most lenders offer interest-only periods of one to five years on investment loans, and you can often extend that if your circumstances support it. Principal and interest repayments build equity faster but increase the monthly cost, so the choice depends on your tax position and long-term strategy.

If you're considering how your current loan structure affects your ability to borrow for a construction project, a loan health check can identify whether refinancing before you apply would improve your borrowing capacity or give you access to lenders with stronger construction loan products.
