How Commercial Property Loans Work in Perth, WA, The Broker's Guide
If you're buying business premises or an investment property outside the residential market, you're stepping into a lending category with its own rules, its own assessment process, and a much narrower lender pool than a standard home loan. Most borrowers who've bought residential property before are surprised by how different it is - not harder, just different, and worth understanding before you start approaching lenders.
Commercial property finance is assessed on two things at once: the income the property generates and the financial strength of the business or borrower behind it. Whether you're a business owner buying your own premises in West Perth, an investor buying a retail tenancy in Joondalup, or a company director acquiring a warehouse in Midland, the lender is weighing the deal on both sides of that equation.
Our team helps buyers across Perth, WA work through the structure of a commercial property loan before they approach lenders, comparing options across 60+ lenders to find the most suitable fit for the asset type and the borrower's circumstances.
Key takeaways
- Commercial loans require deposits of 25–35%, higher than residential.
- Assessment turns on property income and business cash flow together.
- Owner-occupiers buying their own premises carry the strongest lending profile.
Can you get a commercial property loan in Perth, WA?
Yes - commercial property loans are available to business owners, investors and company directors across Perth, WA, though the eligibility criteria and deposit requirements are materially different from a residential mortgage. The lender pool is smaller, the deposit is larger, and the assessment looks at the property as an income-producing asset, not just your personal income. What makes you a strong applicant is the combination of a creditworthy borrower and a property with stable, documentable income.
How does a commercial property loan actually work?
A commercial loan is assessed on two things running in parallel: the property's ability to service the debt from its own income, and the borrower's financial position. Lenders look at the lease quality, the remaining lease term, and the tenant mix alongside your business financials, tax returns and balance sheet. Unlike a residential loan, where your personal income is the primary lens, commercial assessment uses both - and the weight each one carries depends on the lender and the asset class.
The ratio lenders focus on is the debt service coverage ratio, which measures whether the property's net income comfortably covers the loan repayments. A strong, long-dated lease with a creditworthy tenant is worth as much in the assessment as a clean set of business financials, which is why lease quality gets so much attention at application. Where the property has vacancy or short lease terms, the borrower's own financial strength does more of the work.
The borrowers who hit unexpected problems are usually the ones who assumed commercial lending worked like residential - same income assessment, same deposit, just a bigger number. The lender's first question is about the asset, not the applicant, and that shift catches a lot of people off guard at the wrong moment.

What do you need to qualify for a commercial property loan?
Qualification rests on the borrower's financial position and the property itself in roughly equal measure. Lenders want to see that the business or borrower can service the debt and that the asset holds its value independently.
What lenders typically assess:
- › Business financials: two to three years of tax returns and financial statements are standard; lenders assess profit, debt levels and cash flow rather than gross revenue.
- › Lease documentation: a current lease, the tenant's details, the remaining term and any options to renew - a weighted average lease expiry (WALE) of two years or more strengthens the application significantly.
- › Deposit and equity: standard commercial deposits run 25–35% of the purchase price; owner-occupiers buying their own premises may access up to 80% LVR with some specialist lenders.
- › Property type and zoning: office, retail and industrial in commercial zones are assessed differently from specialist-use or rural-zoned assets, and each has its own LVR ceiling.
- › Personal guarantee: almost every commercial loan requires a personal guarantee from the directors or owners of the borrowing entity, regardless of how the loan is structured.
What does a commercial property loan cost in Perth?
The deposit is the most immediate cost difference from residential lending. Standard commercial deposits run 25–35% of the purchase price, which means a $1.5 million office or retail property typically requires $375,000 to $525,000 upfront before costs. Owner-occupiers buying business premises can sometimes access up to 80% LVR with specialist lenders, which brings the deposit closer to the residential range, but that pathway depends on the business's financial profile and the asset class.
Rates are higher than residential loans and are not published as a product in this guide - they vary by lender, loan size, asset class and the borrower's financial position, and quoting a rate without your full picture would be misleading. What does not vary is the structure of the costs: lenders typically charge establishment fees, valuation fees and, on some products, annual covenant review fees. A commercial valuation is also more complex and more expensive than a residential one, as it incorporates the income approach alongside the comparable-sales method.
Transfer duty applies to commercial property purchases in Western Australia and is calculated on the dutiable value of the transaction. There is no first home owner rate of duty for commercial purchases - the standard general transfer duty applies.

How long does it take to get a commercial property loan?
Commercial loan approvals take longer than residential ones, typically four to eight weeks from full application to formal approval, and sometimes longer for complex assets or where the property is vacant or on a short lease. The valuation alone can take one to two weeks, as commercial valuations are more involved than residential ones and the pool of accredited valuers for some asset classes is narrower.
The biggest delays in commercial lending are almost always documentation-related. Lenders require more from both the borrower and the asset than most applicants expect: two to three years of financials, a current lease, body corporate records for strata titles, council rates notices, and often a business plan for development sites. Having these ready before you approach a lender cuts weeks off the process in practice.
When does a commercial property loan not make sense?
Buying commercial property ties up a large deposit in an illiquid asset, and for a growing business, that capital might generate more return if it stayed in the business than it would sitting in bricks and mortar. Rent gives you flexibility - you can relocate, scale up or scale down without a lender's consent and without a revaluation. A business owner who buys premises in year three and wants to expand in year five may find the property constrains them more than the rent ever did.
It also doesn't suit every investor profile. Commercial property requires active management, a tolerance for vacancy risk between leases, and the financial capacity to cover repayments during vacant periods without rental income to offset them. For investors who want a more passive income stream, the additional complexity isn't always justified by the return. If your primary goal is yield and simplicity, residential investment or managed funds may be the cleaner path.
Where I'd push back on a commercial purchase is when the business has been trading for under two years and the owner wants to buy at the same time as they're trying to establish income history for the loan. The lender needs both - and trying to build both at once usually means neither application is as strong as it needs to be.

How to get a commercial property loan in Perth, WA, step by step
The process differs from residential lending in pace and documentation requirements, but the sequence is straightforward once you know what each stage involves.
Step 1: Talk to us
We start by working out whether the asset type, your deposit position and your business financials put you in a strong position to apply, and which lenders on our panel actively write commercial loans for your asset class.
Step 2: Prepare your financial and property documents
We work through what the lender will need from both sides - two to three years of business financials and returns from you, and the lease, title and body corporate documents from the property - so nothing holds up the application.
Step 3: Match to lenders and submit
We compare the lenders on our panel who write this asset type, prepare the application to their requirements, and submit with the full document package to give the credit team what they need at first pass.
Step 4: Manage the valuation and approval through to settlement
We coordinate the commercial valuation, respond to any lender queries, and manage the approval conditions through to settlement alongside your settlement agent.
What goes wrong when people apply for commercial property loans?
Where commercial applications come unstuck:
- › Short or expiring leases: a lease with less than two years remaining - or no lease in place at all - significantly reduces the lender's assessed income from the property and pushes more weight onto the borrower's financials. Waiting until a lease is renewed before applying usually produces a cleaner outcome.
- › Applying to the wrong lender: the major banks have tightened their commercial appetite significantly in recent years. A file declined by a major bank is not a declined application - specialist and second-tier lenders actively write the same asset types, often with more flexible income assessment.
- › Underestimating the deposit: buyers who have only purchased residential property before consistently underestimate the commercial deposit. Budgeting for 20% and discovering the lender wants 30% at valuation creates a gap that is very hard to close quickly.
- › Mixed-use and specialist assets: properties that combine residential and commercial uses, or specialist assets like childcare centres, service stations or medical facilities, attract a narrower lender panel and lower LVRs than standard office, retail or industrial. Knowing your asset class before you make an offer avoids a late-stage finance problem.
For most business owners in Perth, WA, the strongest commercial profile is an owner-occupier buying established premises in a standard commercial zone - that combination gives the lender both the business's financial strength and an asset that's straightforward to value and resell if needed.
Frequently Asked Questions
What is the minimum deposit for a commercial property loan in Perth?
Standard commercial deposits run 25–35% of the purchase price for investment properties. Owner-occupiers buying their own business premises may access up to 80% LVR with some specialist lenders, depending on their financial profile and the asset class.
Can a business owner use a residential property as security for a commercial loan?
Yes, some lenders will accept a residential property as additional security to reduce the commercial deposit required. This cross-secures the two properties, which complicates any future sale or refinance - it's worth understanding the structure before agreeing to it.
How do lenders assess commercial property income in Perth?
Lenders assess the property's net rental income, adjusted for vacancy risk, against the loan repayments using a debt service coverage ratio. A long lease with a creditworthy tenant carries more weight than a short-term or informal arrangement.
Is an SMSF allowed to borrow to buy commercial property?
Yes - self-managed super funds can still enter Limited Recourse Borrowing Arrangements to buy business real property, including commercial premises leased to a related party. The residential LRBA ban that took effect in August 2026 does not affect commercial property held inside an SMSF.
What is the difference between a commercial loan and a business loan?
A commercial property loan is secured against real estate and used to acquire or refinance a property asset. A business loan is typically used for operating capital, equipment or cash flow, and may be unsecured or secured against business assets rather than property.
Should I use a mortgage broker or go directly to a bank for a commercial loan?
A mortgage broker, every time. The major banks have narrowed their commercial appetite considerably, and the lenders most actively writing commercial loans in Perth are specialist and second-tier lenders not accessible through a bank branch. A broker compares the full panel for your specific asset type.
Your Next Steps
Getting commercial property finance right depends on understanding the asset you're buying and structuring the application to match what lenders actually need - a clean lease, documented income and a deposit that fits the asset class. Getting those three things aligned before you make an offer avoids the delays and surprises that trip up most first-time commercial buyers.
The right lender for a commercial property loan depends on your situation, and that's a conversation worth having. Talk to the Launch Finance team or call 08 9367 4222, and we'll compare your options across 60+ lenders.
