Mortgage broker or bank?

A bank can only offer its own loans. A broker compares lenders for you, and in Australia brokers are legally required to act in your best interests. Here's how it works, including how brokers get paid.

What a broker does that a bank can't

How mortgage brokers get paid

The lender pays the broker, not you. Brokers receive an upfront commission when the loan settles and a smaller ongoing trail commission while the loan is active, both based on the loan amount. Commission rates are broadly similar across lenders, and brokers must tell you how they're paid.

The best interests duty

Since 2021, mortgage brokers have been legally required to act in your best interests and prioritise your interests over their own. Bank staff selling their own bank's products don't have the same obligation to compare the market.

When going direct can make sense

If your situation is simple, you're happy with your current bank and it offers you a sharp rate, staying put can be fine. It's still worth checking what the market would offer, because your bank's best offer for a loyal customer isn't always its best offer.

Questions people ask

Is it better to use a mortgage broker or go to a bank?

A broker compares many lenders and must act in your best interests, while a bank offers only its own products. For most people, comparing is worthwhile.

How do mortgage brokers get paid?

By the lender, through an upfront commission when the loan settles and an ongoing trail commission. There's usually no cost to you.

Do mortgage brokers get better rates?

Often, because brokers can request pricing discounts from several lenders and know which lenders are sharpest for your situation.

Is a mortgage broker free?

My service is free to you, because the lender pays the commission.
