What our investment construction service does
The work we do on a build you intend to rent outAn investment construction loan funds a property you build to rent rather than live in, released in stages as the build progresses. The work is finding the lender whose policy on rental income and investment construction fits your project, then holding the drawdowns to schedule so the property starts earning.
Lenders value the land and the finished property together, off the fixed price contract and the approved plans.
Every facility is subject to lender approval and your circumstances, and we give you the honest position before anything is submitted.
We check the project against investment lending policy first
An investment build is assessed on a different set of rules from an owner-occupied one, and those rules are not the same at every lender. We work out which lenders will look at your project before an application is lodged, rather than collecting declines against your credit file.
We work out what the proposed rent does to your capacity
Lenders generally count rental income at a discount rather than in full, and the discount is not uniform across the panel. The same project can produce very different borrowing figures at two lenders. We run the numbers across several before you commit to a contract.
We size the loan against the finished property
The lender values the property as if complete, from your fixed price building contract and the approved plans. Work outside that contract is generally not counted, which matters on an investment where a fit-out decides what the property rents for. We flag those items early.
We run the drawdown cycle so the site keeps moving
Your builder issues a progress claim, the lender usually sends a valuer to confirm the stage is finished, you sign an authority, and the builder is paid. Every week the site is idle is a week the property is not earning. We chase the cycle rather than waiting on it.
We plan for the months before a tenant moves in
Repayments climb with every drawdown, and the rent starts only after the property is finished and let. The gap between full drawdown and the first rent payment is the part investors underestimate. We work out what you carry in that window before the build starts.
We review the structure once the loan converts
At practical completion the facility becomes an ordinary home loan on the drawn balance. On an investment that is the point to review the rate, the repayment type and how the loan sits against the rest of your portfolio. We diarise it rather than leaving it.
Work out the numbers on an investment build
Duty on the land, then the repayment you carry before the rent startsTwo numbers decide whether an investment build works. Transfer duty is payable when the land settles, and the repayment at full drawdown is what you carry in the months between the last stage and the first rent payment.
Work out your WA stamp duty
The dutiable value. Usually the contract price, or the market value if that is higher.
Foreign buyers pay an extra 7% of the dutiable value on residential property in WA.

Who an investment construction loan suits
The investment builds we arrange finance forEvery project below is a build held to rent rather than to occupy, funded progressively against a valuation of the finished property. These are the situations that arrive most often.
Investors building a rental on a lot they have bought
Owners building a second dwelling on a subdivided block
Investors adding a duplex or a pair of villas to a portfolio
Owners living at the front and building to rent at the back
Anyone whose bank has declined a build that the numbers support
How our investment construction process works
Five steps to approval, then a drawdown at every stageThe application runs the same five steps as any loan we write. What follows approval is the part unique to a build: a progress claim, a valuer, an authority and a payment, repeated until the property is finished and ready to let.

About our independent mortgage brokers
The brokers who fund your investment buildIndependent means no franchise above us and no lender owning a share of the business. Nobody upstairs sets a monthly target, so an investment build goes to the lender whose policy on rental income and construction actually fits it. Your bank sells one product; we compare 40+.
Gavin Harrigan has been broking from West Leederville since 2005. Today it runs on a small team, Gavin Harrigan, Justin Richardson and Xavier Prescott, each with their qualifications on the page. You deal with the person who writes your loan, before settlement and after it.
The work runs from a first home loan, through refinancing and investment lending, out to construction, small developments and commercial property. Same broker, whichever end of that you are at.

Why choose us for an investment build
Two lenders will read the same project and lend you different amountsEvery point below is a consequence of how this business is owned, not a slogan about service.
- Included
No franchise, no head office quota
We do not pay a franchise fee, so nobody upstairs sets a monthly target for us to hit. That removes the main reason a broker recommends the wrong loan.
- Included
No lender owns a share of us
The banks have no stake in this business and no claim on where files go. Your bank has one loan to sell you. We do not.
- Included
40+ lenders, one shortlist
We compare 40+ bank and non-bank lenders, then explain why the shortlist looks the way it does. Policy differences decide more applications than rate does.
- Included
We will tell you when the answer is no
If refinancing does not actually save you money, we say so and you leave the loan where it is. A wrong loan costs more than the fee it earns.
- Included
The same broker after settlement
You keep dealing with the person who wrote the loan. We review it as rates and your circumstances change, not once and then never again.

Common questions about investment construction loans
What is an investment construction loan?
It is a construction loan for a property you build to rent out rather than occupy. Money is released in stages as the build progresses and interest applies only to the drawn balance. Lenders assess it under their investment lending policy, which differs from their owner-occupier policy.
Do lenders count rent I have not received yet?
Many will count the proposed rent on the finished property, usually supported by a rental assessment from the valuer. It is generally counted at a discount rather than in full. How much of it counts varies by lender, which is why the same project produces different borrowing figures.
How is this different from an owner-occupier construction loan?
The build mechanics are the same, including the progress stages and the drawdown cycle. The assessment differs, because lenders apply investment lending policy and read rental income under their own rules. Deposit expectations and product choice can also differ, subject to lender approval.
Can I build an investment property on a block I already own?
Often yes. Equity in the land can contribute towards or cover the deposit on the construction facility, subject to a current valuation and your serviceability. Owners subdividing an existing block and building at the rear do this regularly, and it is one of the more common files we see.
Can I fund two dwellings on one title this way?
A duplex or a second dwelling can usually sit under a construction facility. Once a project runs to several dwellings, or the intention is to build and sell, lenders generally move it into development finance and assess it on the project rather than mainly on you.
What do I pay while the property is being built?
Interest on the drawn balance, which rises with every stage, plus any drawdown or valuation fees the lender charges along the way. There is no rent coming in until the property is finished and let, so plan for the gap between the final drawdown and the first tenant.
Is the interest deductible during construction?
That is a question for your accountant, and it turns on your circumstances and on when the property becomes available to rent. We do not give tax advice. What we can give you is exactly what interest was charged and when, so your accountant has accurate figures to work from.
