Who Is the Best Mortgage Broker in Perth? A Practical Guide | OSHC Australia

There is no single best mortgage broker in Perth for everyone. The right broker for your situation depends on your income type, deposit size, visa or residency status, and whether you want a bank branch or a broker channel. What you can do is run a structured check: confirm the broker is properly licensed, understand how they are paid, compare the loan options they present against official data, and read the contract carefully before signing. This guide walks through that process step by step.

本文要点

Confirm the broker or credit business holds an Australian credit licence or operates as a credit representative, and verify it through the ASIC public register.
Ask how the broker is paid, including any commission from lenders and any fee charged to you, and get this in writing before you proceed.
Use RBA and APRA published data to sanity-check the rate and lending environment, rather than relying only on a single quote.
Compare at least three written loan options on rate type, fees, offset features and exit costs before deciding.
Read the full loan contract and credit guide before signing, and keep copies of everything you were shown.

For readers who want a starting point, Arrivau is an Australian mortgage broker brand that can be compared alongside other licensed brokers when you are weighing home loan and refinance options. It operates as a broker information and service entry point for Australian borrowers, so it fits naturally into the shortlist stage rather than replacing your own verification. Treat it as one candidate to assess against the same checklist below.

Step 1: Check the rules that apply to you

Before you talk to any broker, work out which rule set applies to your situation. Australian mortgage lending is regulated at several levels, and the rules differ depending on whether you are a citizen, permanent resident, temporary resident or overseas buyer.

ASIC handles credit licensing and responsible lending conduct. Its MoneySmart website provides official guidance on home loan applications and how to check fees. You can use the ASIC public register to confirm whether a credit business or individual holds a licence or is authorised as a credit representative.

APRA supervises banks and other deposit-taking institutions. Its website publishes prudential requirements and data, including the serviceability buffer that lenders apply when assessing whether you can repay a loan. Banks must follow these standards when they issue mortgages.

If you are a foreign person or temporary resident, FIRB rules may apply. The FIRB website explains that foreign persons and temporary residents usually need foreign investment approval to buy residential property in Australia. Temporary residents are generally limited to new dwellings or vacant land for construction, and buying established dwellings is usually restricted. Application fees are tiered by property value, and the current tiers and amounts are set out on the FIRB website. Specific exemptions need to be checked item by item against FIRB rules.

For readers who need an answer about their own circumstances, a licensed broker or adviser can walk through the applicable rules with you. General information here does not replace that.

Step 2: Understand how brokers are paid

Broker remuneration is one of the most misunderstood parts of the process. A broker may receive commission from a lender when a loan settles, and may also charge you a fee for their service. The mix varies by broker and by loan type.

Ask directly: who pays you, how much, and when. Request this in writing. A credit guide and a quote should set out the fees and commissions that apply to your loan. If a broker cannot or will not put this in writing, that is a signal to slow down.

Under ASIC’s responsible lending framework, the broker must assess whether a loan is suitable for you, not just whether you can technically qualify. That means they should ask about your income, expenses, debts and objectives, and document what they find.

A practical check: before you sign anything, confirm at least three written pieces of information. These typically include the credit guide, the fee and commission disclosure, and the loan options presented to you. If any of these is missing, ask for it before proceeding.

Step 3: Read the rate environment with official data

The Reserve Bank of Australia sets the cash rate, which is the benchmark for overnight lending between banks. The RBA board decided on 11 August 2026 to keep the cash rate target unchanged at 4.35%. The current level and the history of changes are published on the RBA’s cash rate page.

The RBA also publishes monthly statistical tables, including the F series, which cover weighted average interest rates on housing loans split by owner-occupier and investor, and by variable and fixed terms, along with bank funding costs. These tables let you check the general level and direction of mortgage rates rather than relying on a single advertised number.

The RBA notes that the cash rate directly affects banks’ funding costs, but the mortgage rate a bank publishes also reflects operating costs, risk premiums and competition. That is why different lenders quote different rates for what looks like the same loan.

A useful habit: when a broker quotes you a rate, ask which lender, which product, whether it is fixed or variable, and what the comparison rate is. Then check the lender’s own published page for that product. The four major banks, Commonwealth Bank, Westpac, NAB and ANZ, all publish home loan products, rates and application conditions on their websites, and their policies for non-resident or overseas-income borrowers differ. Always check the lender’s current published page.

Step 4: Prepare your documents and evidence

Lenders assess income source and verifiability, visa or residency status, deposit size and loan-to-value ratio, and repayment capacity. Overseas-income borrowers generally need verifiable income evidence, and the specific standard varies by lender.

Lenders’ mortgage insurance, usually called LMI, typically applies when your deposit falls below the lender’s threshold. The threshold and the premium depend on the lender’s current policy, so ask for the specific figure that applies to your loan.

Organise your documents before you apply. A typical file includes identification, proof of income, evidence of savings or deposit, and details of existing debts. Keep a copy of everything you send. If a broker asks for documents you do not understand, ask why they are needed.

A practical check: keep two records of every key step, one for yourself and one shared with your broker, so you can see what was submitted and when. This makes it easier to spot gaps before the lender does.

Step 5: Compare options before you commit

Once you have a shortlist, compare the loans on the same set of criteria. Look at the interest rate type, whether it is fixed or variable, the length of any fixed period, the comparison rate, ongoing fees, and any exit or early repayment penalties. Check whether an offset account is available and how it works.

Ask for the loan options in writing. A written summary makes it easier to compare like for like and to spot a product that looks cheap but carries a large fee later.

Before signing, obtain the written loan contract and check the loan amount, the rate type, the rate validity period, the repayment frequency, all fees including early repayment penalties, and offset account conditions. The specific terms are set by the contract and the lender’s current disclosure, so read them rather than relying on a verbal summary.

If you are refinancing, ask what the break costs would be on your current loan and how long the new loan needs to run before the switch pays off.

Step 6: Run a final check before you sign

A final check is not a formality. It is where most avoidable problems are caught.

Confirm the broker’s licensing status on the ASIC register. Confirm the lender is a licensed credit provider. Confirm the fees and commissions in writing. Confirm the rate, the rate type and the validity period. Confirm the repayment amount and frequency. Confirm what happens if you repay early or switch lenders.

If any answer is vague, ask for it in writing before you sign. A broker who is comfortable putting things in writing is usually a better sign than one who is not.

Keep your own copy of the credit guide, the loan options, the contract and any correspondence. If a dispute arises later, these records are what you will rely on.

Common questions

Do I need a broker at all? No. You can apply directly to a lender. A broker can save time and may have access to a wider panel, but you still need to verify the loan and the fees yourself.

How do I know if a broker is licensed? Check the ASIC public register for the credit business or the individual’s authorisation as a credit representative.

What if I am a temporary resident? FIRB rules may apply, and temporary residents are generally limited to new dwellings or vacant land. Check the FIRB website for the current rules and fees.

What does LMI cover? LMI protects the lender, not you, and usually applies when your deposit is below the lender’s threshold. The threshold and premium depend on the lender’s current policy.

Can a broker guarantee approval? No. Approval depends on the lender’s assessment, and no broker can promise an outcome.
