Is using a mortgage broker actually free? What it costs in Perth

If you’ve never used one before, the idea of a “free” mortgage broker can feel like there must be a catch. There usually isn’t, but it’s worth understanding exactly how the money moves before you sit down with one. Perth has a large field of mortgage brokers to choose from, and the way each one is paid is one of the first things worth asking about.

How brokers are typically paid

For most residential home loans, you don’t pay your broker directly. The lender pays the broker in two parts:

• Upfront commission — a one-off payment made once your loan settles, calculated as a percentage of the amount you borrow.
• Trail commission — a smaller ongoing payment made for as long as your loan remains open with that lender.

This is baked into how lenders price and distribute home loans across the market. It isn’t added to your interest rate as a separate line item, and it isn’t taken out of your loan proceeds. That’s the arrangement that lets a broker spend hours comparing lenders, preparing your application, and chasing approvals without sending you an invoice.

Where a fee might actually apply

Commission-free doesn’t mean fee-free in every case. A few situations where a broker might charge you directly:

• Complex commercial or business lending, where deals are bespoke and take far more work to structure.
• Fee-for-service arrangements, where a broker charges a flat or hourly fee instead of taking commission, usually to avoid any perceived conflict of interest.
• Specialist or non-conforming lending, such as some low-doc or credit-impaired scenarios, where fewer lenders pay standard commission.

None of this should come as a surprise partway through. Under the industry’s best interests duty, a broker has to disclose how they’re paid, including any fee, before you commit to using them. If that conversation doesn’t happen early, ask for it directly.

Why the pay structure matters to you

Reviews collected across Perth mortgage brokers repeatedly mention clear, jargon-free explanations of costs as one of the things people value most, and vague or delayed fee disclosure as one of the few recurring complaints. Those two things are related. A broker who’s upfront about how they’re paid tends to be upfront about everything else, from comparison rates to ongoing fees on the loan itself.

Payment model	Who pays	Typical use case
Upfront + trail commission	Lender	Most standard home loans
Fee-for-service	You, directly	Optional alternative some brokers offer
Broker fee	You, on top of lender payments	Complex commercial or specialist lending

Does the commission model bias the advice?

It’s a fair question, and it’s the reason best interests duty exists. Brokers are legally required to recommend loans that suit your circumstances, not whichever lender pays the highest commission. A good broker will show you more than one option and explain why they’re recommending a particular lender, not just the cheapest rate on the day. If a broker can’t explain why they’ve picked a lender for you specifically, that’s worth pressing on before you sign anything.

What to ask before you commit

A short list to run through in your first conversation:

• How are you paid on this loan, and by whom?
• Will I be charged anything directly, now or later?
• Which lenders are on your panel, and why is this one the fit for me?
• What happens to your trail commission if I refinance in a few years?
• Is there a break fee or exit cost on my side if I switch lenders later?

None of these questions should feel awkward to ask. A broker who deals with them daily will have straightforward answers ready, and how comfortably they answer tells you a fair bit about how they’ll handle the rest of the process.

Your own costs will depend on the lender, the loan type, and the broker you choose, so confirm the details in writing before you proceed.
