A Second Set of Eyes on the Whole Market

When your fixed term is ending, a mortgage broker can shop your refinance across multiple lenders simultaneously — something that's much harder to do efficiently on your own. They'll compare not just headline rates, but cashback offers, fees, and loan structures across the market at once.

Because brokers deal with lenders regularly, they often know which banks are currently pricing most competitively for refinancers, information that isn't always obvious from public rate sheets alone.

Market-Wide Comparison

Compares rates, cashback and fees across multiple lenders at once.

Negotiation

Can push for better cashback or rate terms using their relationships with lenders.

Because a broker's service is typically free, using one to refinance costs you nothing extra while potentially surfacing a better deal than you'd find alone.

What to Ask a Broker About Refinancing

Get clarity before committing to a switch.

What will break fees cost?

Ask them to help estimate this against your current bank before deciding to switch.

What cashback is realistically available?

Ask them to compare offers across their full lender panel, not just one or two banks.

Does this suit my next 3–5 years?

A good broker considers your future plans, not just the cheapest rate today.
