Quick Answer: A mortgage adviser compares home loan options across multiple banks, handles the application paperwork on your behalf, and negotiates rates and terms - most charge you nothing directly, since they're paid a commission by the lender once your loan settles.
What the Job Actually Involves
A mortgage adviser's core job is matching your situation - income, deposit, credit history, and goals - against multiple lenders' criteria, rather than just the one bank you'd otherwise walk into. They gather your documents, submit applications, chase approvals, and often negotiate a better rate or cashback offer than you might secure walking in alone.
Do You Actually Need One?
You're not required to use a mortgage adviser - going directly to your own bank is entirely valid, especially if you already bank with a lender offering competitive rates. But an adviser's value comes from comparison: they see live rates and policies across most major banks and some non-bank lenders, which can matter a lot if your situation is slightly outside standard criteria (self-employed income, a smaller deposit, or a less conventional property type).
- Straightforward situation with a lender you already trust - going direct can work fine
- Self-employed, complex income, or smaller deposit - an adviser's cross-lender view often helps
- Want to compare without contacting five banks yourself - an adviser does that legwork
