What our renovation finance service does
The work we do on a renovation, from scope to final paymentA renovation loan funds work on a property you already own, either as a lump sum against your equity or as a construction facility drawn in stages. The work is matching the structure to the scope, getting the valuation right, and running the progress payments where the job needs them.
The scale of the work decides the structure, and lenders are consistent about where that line falls.
Every facility is subject to lender approval and your circumstances, and we tell you what is realistic before you commit to a builder.
We work out which structure your renovation needs
A loan increase against equity and a construction facility are different products with different paperwork. Ask for the wrong one and the application stalls at assessment. We look at the scope of work first and tell you which structure lenders will treat it as.
We establish the equity you have to work with
Almost every renovation is funded off the equity in the property, so the valuation comes before the plans. On a straight loan increase the lender values the house as it stands. On a construction facility the valuation is done as if the work is complete.
We assemble the file a renovation lender asks for
Structural work needs a builder's fixed price contract, plans and specifications, the relevant council or shire approval and permit, the builder's registration and insurance, and a progress payment schedule. A cosmetic loan increase needs far less. We tell you which list applies to you.
We manage the progress payments to your builder
Where the work is funded as a construction facility, money is released stage by stage rather than in a lump sum. Your builder claims, the lender usually inspects, you authorise, and the builder is paid. We hold that cycle together so the trades are not left waiting.
We show you what the extra borrowing repays at
Adding to a loan changes the repayment for the remaining term, and stretching the term lowers the repayment while adding interest over the life of the loan. Both are legitimate choices. We put the numbers side by side so you pick with the figures in front of you.
We review the whole loan while it is open anyway
A renovation puts your loan back on the table, which makes it the natural moment to check the rate and structure you are on. If moving lenders does not actually improve your position we will say so, and you keep the loan you have.
Work out what the renovation costs to fund
What the extra borrowing repays at, and what you can borrowTwo numbers matter before you talk to a builder. What the additional borrowing adds to your repayment, and what a lender is likely to lend you against your income and the equity you hold.
Work out your repayments
What you need to borrow, not the purchase price.

This is an estimate. It assumes the rate stays where you put it for the whole term and it does not include fees, lenders mortgage insurance, offset balances or extra repayments. Your real repayment depends on the lender and on approval.

What actually lands in your accounts. Include a partner if you are buying together.
Groceries, fuel, insurance, childcare, subscriptions. Lenders apply a minimum benchmark, so a low figure here will not be taken at face value.
Car, personal, HECS, existing mortgages.
The limit, not the balance.
Lenders count between 2.5% and 3.8% of every card limit as a repayment, whether you owe anything or not.
An example figure to change, not a rate on offer.
Lenders test you at a rate above the one you pay. Three percentage points is the level APRA expects, so you are being assessed at 9.00%.

How a renovation gets funded
Four ways to fund the work, and what each one suitsRenovations are funded in more than one way, and the right structure depends on the size of the job and on the loan you already hold. The difference shows up in the paperwork, in the valuation and in how the money reaches your trades.

Who a renovation loan suits
The renovations we arrange finance forEvery job below is work on a property the owner is keeping, funded either as a loan increase or as a staged construction facility. These are the situations that arrive most often.
Owners updating a kitchen, a bathroom or the flooring
Families extending the house rather than moving out of the suburb
Owners adding a second storey or taking out internal walls
Investors improving a rental before it goes back on the market
Buyers renovating a place they have only just settled
How our renovation loan process works
Five steps, then either a lump sum or a set of progress paymentsThe application runs the same five steps as any loan we write. What happens after approval depends on the structure: a cosmetic job is funded in one amount, and structural work is drawn stage by stage against your builder's claims.

About our independent mortgage brokers
The brokers who fund your renovationIndependent means no franchise above us and no lender owning a share of the business. Nobody upstairs sets a monthly target, so a renovation is structured the way it should be rather than the way one lender's product list allows. Your bank sells its own; 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 renovation finance
The wrong structure is what stalls a renovation, not the rateEvery 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 renovation loans in Perth
What is a renovation loan?
It is finance for improving a property you already own. Smaller cosmetic work is usually funded by increasing your existing home loan against your equity. Structural work is usually funded as a construction facility with a builder's contract, where the money is released in stages as the job progresses.
Do I need a builder's contract to borrow for a renovation?
For a cosmetic update, generally not: a loan increase against equity is assessed on your income and the value of the house. For structural work, most lenders want a fixed price contract, plans, the relevant permit and a progress payment schedule before they will lend.
Where is the line between cosmetic and structural work?
Broadly, cosmetic work replaces what is already there and structural work changes the building. New kitchens, bathrooms, flooring and paint usually sit on the cosmetic side. Removing walls, adding a storey or extending the footprint puts the job into construction territory, and lenders draw that line slightly differently.
Will the lender value my house on what it is worth after the work?
On a construction facility, yes: the valuation is done as if the work is complete, from the plans and the fixed price contract. On a straight loan increase the lender values the house as it stands today. Which structure you use therefore changes the valuation you get.
Can I borrow for a renovation if I have little equity?
Your options narrow considerably, because most renovation lending is secured against equity in the property. It is not automatically no. We will look at your position honestly and tell you whether it works now or whether it is worth waiting, subject to lender approval.
How is the money paid to my builder?
On a loan increase the funds come to you and you pay the trades as the work is done. On a construction facility the builder issues a progress claim, the lender usually inspects, you sign an authority, and the lender pays the builder directly at each stage.
Can I do the work myself and borrow for materials?
Doing the work yourself moves you towards owner-builder territory, which fewer lenders will fund and which carries its own approval requirements. A smaller cosmetic job funded as a loan increase is different, because the lender is not funding a building contract at all. We will tell you which side yours falls on.
Should I renovate or knock down and rebuild?
Get both costed by a builder before deciding, because the answer changes with the condition of the house and the scope of the work. Once you have the two numbers we will tell you how each one funds and what each one costs to hold while the work is underway.
