Construction Investment Loans: What Not to Do

Construction Finance for Investment Property Works Differently

A construction loan for an investment property releases funds in stages as the build progresses, and you're only charged interest on what's been drawn down. This is different to a standard home loan where you receive the full amount upfront. The lender holds the remaining funds and releases them after each inspection confirms the builder has completed the relevant stage.

Consider a police officer building a duplex as an investment. With a loan amount of $450,000, the lender might release 10% at slab stage, another 20% at frame stage, and so on through to completion. In the early months, you're only paying interest on the portion drawn down, not the full loan amount. Once construction finishes, the loan converts to a standard investment loan with principal and interest repayments or interest-only if you've structured it that way.

The mistake some people make is treating the construction phase like a standard loan application. The lender needs council approval, registered builder contracts, and a fixed price building contract before they'll even consider your application. Miss one of those, and the application stalls.

Why Lenders Treat Investment Construction Differently

Lenders view investment property construction as higher risk than building your own home. You're not living in it, and if the build runs over time or budget, you're still carrying holding costs without rental income. That's why most lenders require at least a 10% to 20% deposit, and some won't lend to owner builders on investment projects at all.

In our experience, officers building investment properties need to show they can service both the construction loan interest and their existing mortgage or rent during the build. A registered builder with a fixed price contract gives the lender confidence the project will finish on time and on budget. A cost plus contract, where the builder charges for labour and materials with a margin on top, makes lenders nervous because the final cost isn't locked in.

Some lenders also require you to commence building within a set period from the disclosure date, usually six to twelve months. If your development application drags on or the builder can't start on time, you may need to reapply or extend the approval, which can mean updated valuations and income checks.

Progress Payment Schedules and How Drawdowns Work

A progress payment schedule outlines when the builder gets paid and when the lender releases funds. Typical stages include base, frame, lock-up, fixing, and practical completion. The lender sends a progress inspector to confirm each stage is done before approving the drawdown. You're charged a progressive drawing fee each time, usually $300 to $500 per inspection, which adds up across five or six stages.

Between drawdowns, you're paying interest only on the amount drawn down so far. If $150,000 has been released by frame stage, you're paying interest on that, not the full loan amount. This keeps repayments lower during construction, but you still need to budget for those instalments on top of your existing commitments.

The builder will invoice the lender directly for each progress payment. The lender pays the builder after the inspection clears, not before. If the inspector flags an issue, the drawdown gets held up until it's fixed. That can delay the builder and push out your completion date, which is why choosing a registered builder with a solid reputation matters.

Land and Construction Packages vs Buying Land First

A land and construction package means you buy the land and arrange the build in one transaction, often with a project home builder. The lender provides finance for both the land purchase and the construction in a single loan. If you already own suitable land, you apply for construction finance only, and the lender uses the land as part of your equity.

Buying land first gives you more control over the site and builder, but it also means you're holding land while you sort out council plans and a building contract. If you're borrowing to buy the land, you'll be paying interest on that loan while construction finance is being arranged. A house and land package can streamline the process because the builder handles the development application and the lender knows exactly what's being built.

Officers working shifts often prefer the certainty of a package because the builder locks in a price and a timeline. The downside is less flexibility on design and layout. If you're building a custom design, expect the lender to ask for detailed plans, a quantity surveyor's report, and sometimes a second valuation.

Fixed Price Contracts Are Non-Negotiable for Most Lenders

Most lenders won't approve construction finance for an investment property without a fixed price building contract from a registered builder. The contract needs to specify the total build cost, the progress payment schedule, and a completion date. Cost plus contracts or owner builder arrangements are either declined outright or require a much larger deposit and higher interest rates.

A fixed price contract protects the lender because they know the final cost and can value the completed property with confidence. It also protects you from cost blowouts, though you're still exposed if the builder goes under or walks off site. That's where building insurance and choosing a builder with a solid track record becomes critical.

If your build includes non-standard features or high-end finishes, the valuer needs to be confident the completed property will be worth the loan amount. Overcapitalising is a risk with investment properties because the rental return may not justify the build cost, and that affects your borrowing capacity for future purchases.

What Happens After Practical Completion

Once the build reaches practical completion and the final inspection is done, the loan converts from construction to a standard investment loan. At that point, you'll either start making principal and interest repayments or switch to interest-only if that's what you've arranged. The construction phase is over, and you're now holding a rental property with a mortgage against it.

If you've structured the loan as interest-only, your repayments stay lower, which can help with cash flow while you're building equity in the property. Most lenders offer interest-only periods of one to five years on investment loans, after which the loan reverts to principal and interest unless you refinance.

The rental income should ideally cover most or all of the mortgage repayment, but in the early years of ownership, you may be negatively geared, meaning the rental income doesn't cover the interest and holding costs. That shortfall is tax-deductible, but you still need to service the gap from your salary, which is where your roster and overtime income gets factored into the application.

Council Approval and Development Applications Take Time

Lenders won't release funds until council approval is in place, so the development application process sits on your critical path. Depending on the site and what you're building, council approval can take three to six months or longer if there are objections or design changes required.

If you're building a duplex or townhouse, the development application is more involved than a single dwelling. Some councils have specific requirements around setbacks, parking, and landscaping that can knock back your first submission. That delays the build start and pushes out your construction finance approval.

Get the development application lodged as soon as you've settled on the land and locked in a builder. The sooner council signs off, the sooner the lender can issue formal approval and you can start drawing down funds. Some lenders will give conditional approval before council approval is finalised, but they won't release funds until the DA is stamped.

How Shift Work and Overtime Affect Your Application

Lenders treat overtime and shift allowances differently depending on whether they're guaranteed or discretionary. If your roster includes penalty rates and allowances that appear on every payslip, most lenders will count 80% to 100% of that income. If overtime is irregular, they may shade it or exclude it entirely.

For construction finance on an investment property, the lender is assessing whether you can service the construction loan interest, your existing home loan or rent, and any other debts while the build is underway. Once the property is finished and tenanted, they'll factor in rental income, but until then, it's all on your salary.

If you're refinancing an existing investment loan to fund the construction, the lender will treat it as a new application and reassess your income and commitments. That's where working with a broker who understands police pay structures makes a difference, because they know which lenders will count shift penalties and which won't.

Call one of our team or book an appointment at a time that works for you. We'll walk through the application, the progress payment schedule, and how the drawdowns line up with your build timeline. Construction finance for investment properties has more moving parts than a standard home loan, and getting the structure right from the start saves time and holding costs down the line.
