Owner builder finance
Owner builder finance funds a build you are managing yourself instead of handing to a registered builder. Fewer lenders write it and they typically lend a lower proportion of the finished value, so we tell you plainly whether your project is fundable.
- Genuinely harder than a standard construction loan, and we say so.
- Fewer lenders offer it, at a lower proportion of the finished value.
- You need an owner-builder approval and a costing schedule trade by trade.
- Sometimes a land loan plus an equity release is the better answer.

What our owner builder finance service does
The work we do on an owner-build, starting with whether it is fundableOwner builder finance is a construction loan for a build you are managing yourself rather than handing to a registered builder. The work starts with an honest assessment of whether it can be funded, then moves to lender selection, a much stricter file, and drawdowns that rest on a valuer rather than a builder's claim.
Fewer lenders offer owner-builder finance, and those that do typically lend a lower proportion of the finished value.
Every facility is subject to lender approval and your circumstances, and we give you the realistic position before anything is submitted.
We tell you first whether the project is fundable
Owner-builder lending is the part of construction finance where an honest no saves the most money. We look at your approval, your costings and your equity before anything is submitted. If it does not work as an owner-build, you hear that from us rather than from three declines.
We go to the lenders who write owner-builder loans at all
Most lenders do not fund owner-builders, and applying to one that does not is a decline recorded against your file for nothing. Knowing which part of the panel to approach is most of the work here, and it is why lender selection comes before the paperwork.
We assemble the file an owner-builder lender demands
Your owner-builder approval and any relevant trade background, a costing schedule trade by trade, quotes from the subcontractors you intend to use, and a realistic contingency because owner-builds run over more often. Lenders are stricter about this file than any other construction file.
We work out the gap you have to fund yourself
Lenders typically fund a lower proportion of the finished value on an owner-build, so the difference between what you borrow and what the project costs is yours to cover. That gap is the number the whole project turns on. We establish it before you commit to anything.
We compare a construction facility against land plus equity release
An owner-builder construction facility is not the only route. Borrowing against the land and releasing existing equity can fund a build outright, without the lender supervising progress claims. It is often the workable answer when a construction facility is declined, and we price both.
We handle drawdowns without a builder's progress claim
There is no builder issuing claims on an owner-build, so each release rests on the lender's valuer confirming the stage is genuinely complete. That makes documentation and timing matter more, not less. We keep the inspection cycle moving so your trades are paid on schedule.
Work out the numbers on an owner-build
Duty if you are buying the land, then the repayment at full drawdownIf you are buying the block, transfer duty is payable at land settlement rather than at the end of the build. The other number to have early is the repayment at full drawdown, because that is the one you carry once the project is finished.
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.

How an owner-build gets funded
Three routes, including the one that is not an owner-builder loanAn owner-builder construction facility is one way to fund a build you are managing yourself, and it is not always the best one. The alternatives are worth pricing before you commit, because the cheapest finance is not always the finance labelled for the job.
- Owner-builder construction facility
How it works
Drawn in stages against your costing schedule and the valuer's inspections
Worth knowing
Written by considerably fewer lenders, typically at a lower proportion of the finished value
- Land loan plus an equity release
How it works
You borrow against the land and existing equity, then fund the build yourself
Worth knowing
Often the workable answer when a construction facility is declined
- Registered builder on a fixed price contract
How it works
The standard construction loan path, drawn against the builder's progress claims
Worth knowing
The widest lender choice, and worth pricing before you commit to owner-building
Bring us the approval and the costings and we will tell you which of these three your project realistically fits. If that is the third one, we will say so.

How the process runs on an owner-build
Five steps, with a harder file and a valuer at every stageThe application runs the same five steps as any loan we write, with more documentation at the front and a stricter assessment throughout. Each drawdown then rests on the lender's valuer confirming the stage is complete, because there is no builder's progress claim to rely on.

About our independent mortgage brokers
The brokers who will give you the honest answerIndependent means no franchise above us and no lender owning a share of the business. Nobody upstairs sets a monthly target, so there is nothing to gain from talking you into an owner-build that will not fund. Your bank may not write these at all; 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.

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.

Common questions about owner builder finance in Perth
Can I get a construction loan as an owner-builder?
It is possible, though considerably fewer lenders offer it and they typically lend a lower proportion of the finished value. You need an owner-builder approval, a detailed costing schedule and evidence you can fund any shortfall. We will tell you honestly whether your project is fundable.
Why is owner builder finance harder to get?
A lender funding a registered builder has a fixed price contract, a builder's registration and indemnity insurance behind the work. An owner-builder file has none of those. More of the risk of the build stalling or running over sits with the lender, and their policies reflect that.
What does an owner-builder have to supply?
Your owner-builder approval from the Building Commission and any relevant trade background, a detailed costing schedule trade by trade, quotes from the subcontractors you intend to use, a realistic contingency because owner-builds run over more often, and evidence you can fund the gap between what you borrow and what it costs.
How much of the cost will a lender fund?
Less than they would fund for a registered builder, and how much less depends on the lender and on your project. There is no figure that holds across the panel, because the policies differ. We give you the number that applies to your file before you commit to anything.
How do drawdowns work without a builder?
There is no builder's progress claim, so each release rests on the lender's valuer inspecting and confirming the stage is genuinely complete. You sign an authority and the funds are released, then the cycle repeats. Documentation and timing matter more here than on a standard construction file.
Do I need my owner-builder approval before I apply?
Yes, in practice. Lenders that write owner-builder loans want the approval as part of the file, alongside your costings and your trade background. Start the approval and the finance conversation at the same time, so you are not holding one while waiting on the other.
What if no lender will fund my owner-build?
There is usually another route. Borrowing against the land and releasing existing equity can fund a build without a construction facility at all, if you hold enough equity. The other honest option is putting the work with a registered builder, which opens the whole panel.
Is owner-building actually cheaper?
Sometimes, and it depends entirely on your trade contacts, your time and how accurate your costings are. Owner-builds run over more often than contracted builds, and you fund the overrun yourself. Price the registered builder path as well before deciding, so you are comparing two real numbers.
