From First Call to Keys: How a Mortgage Broker Actually Works

When you engage a mortgage broker, you’re signing up for a structured process: they clarify your goals, collect and interpret your financials, design a loan strategy, shortlist lenders, manage your application, and guide you through pre‑approval, formal approval and settlement. Behind the scenes, they’re translating your situation into lender language and navigating credit policy so your loan has the best chance of being approved on the right terms.

This guide walks you step‑by‑step through what actually happens so you can move confidently this week, whether you’re buying, refinancing, investing or self‑employed.

1. What a mortgage broker really does (big picture)

Before we break it into steps, it helps to understand the end‑to‑end flow.

In practical terms, a good broker will:

1. Clarify your goals – home, investment, refinance, equity release, business needs.
2. Assess your numbers – income, debts, living costs, credit history, deposit/equity.
3. Design a structure – loan splits, fixed vs variable, offset vs redraw, P&I vs interest‑only.
4. Compare lenders and products from their panel (often 20–40 lenders).(16)
5. Run serviceability checks using lender calculators (with at least a 3% buffer above actual rates, in line with APRA guidance).(5)
6. Prepare and lodge your application, packaging your story to fit policy.
7. Shepherd the deal to settlement – valuation, conditions, documents and timing.
8. Review and renegotiate over time as rates, policy and your life change.

2. Step 1 – The first conversation (15–45 minutes)

2.1 Purpose of the first chat

The first call or meeting is about fit and feasibility, not forms.

Your broker will aim to:

• Understand your goal and timing – buying in 3 months vs 18, refinancing this quarter, funding a business purchase, etc.
• Quickly check for red flags – recent credit issues, tax debt, unpaid defaults.
• Get a feel for income type – PAYG, self‑employed, contractor, multiple entities.
• Gauge deposit/equity and rough borrowing range.

They’ll usually give a ballpark view: “Based on what you’ve told me, it sounds like borrowing around $800k is realistic, but we need your documents to confirm.”

2.2 What you should prepare or ask

You don’t need full paperwork for this call, but have a rough idea of:

• Your income (salary, bonuses, distributions, rent)
• Your debts (cards, HECS/HELP, personal or business loans)
• Savings and existing property values

Use this call to ask:

• How many lenders they work with and what types (majors, second‑tier, non‑banks)
• Whether your situation needs a specialist broker (common for self‑employed, complex investors, SMSFs – see Specialist vs generalist mortgage brokers)
• How they’re paid and how Best Interests Duty applies (your sibling article will cover this in depth)

By the end of Step 1 you should have a clear “Yes, it’s worth proceeding” or “We need to fix X first”.
