10 Critical Questions to Ask a Mortgage Broker in 2026

Introduction

Choosing the right mortgage broker determines whether you secure competitive interest rates, maximize your borrowing capacity, or face rejection from lenders. A mortgage broker acts as your intermediary between you and 40+ lenders across Australia, comparing loan products, negotiating rates, and managing applications from pre-approval through settlement. In 2026, with APRA’s tightened serviceability buffer at 3%, debt-to-income ratio monitoring, and the Best Interests Duty enforced, asking the right questions protects your financial interests and saves thousands in interest charges.

This guide addresses the 10 critical questions first home buyers, refinancers, and property investors must ask before engaging a broker to ensure professional credentials, transparent fee structures, and ongoing support that delivers optimal loan outcomes.

Question 1: Are you a member of the MFAA or FBAA?

Professional membership validates your broker’s credentials and ongoing education. The Mortgage & Finance Association of Australia (MFAA) and Finance Brokers Association of Australia (FBAA) enforce strict codes of conduct, requiring annual professional development and minimum insurance standards.

Why membership matters:

• MFAA members hold Certificate IV in Finance and Mortgage Broking minimum
• Both associations enforce Best Interests Duty compliance
• Professional indemnity insurance protects clients from broker errors
• Disciplinary processes exist for breaches protecting consumers

What to verify:

• Request MFAA or FBAA membership number for confirmation
• Check ASIC’s Professional Registers for license verification
• Confirm current professional indemnity insurance
• Verify no disciplinary actions exist on their record

Secured Nest maintains active MFAA membership with 20+ hours of continuing professional development completed in 2025, operating under Australian Credit Licence 389328.

Question 2: How many lenders are on your panel?

Lender panel diversity directly impacts access to competitive rates and specialized loan products. Brokers with 40+ lenders provide genuine comparison, while smaller panels may limit options.

Panel size reveals:

• Major aggregators provide access to 40-60+ lenders
• Bank-owned brokers restrict choice to parent company products
• Small panels (under 20) limit specialized financing options
• Non-bank access delivers 0.15%-0.40% rate savings versus major banks

Why panel diversity matters:

Key questions:

• Which major banks are on your panel? (ANZ, CBA, NAB, Westpac baseline)

• Do you work with non-bank lenders like Pepper Money or Liberty?

• Can you access government scheme lenders?

Secured Nest accesses 40+ lenders across major banks, non-banks, and credit unions, ensuring competitive comparison quotes.

Question 3: How do you get paid and are there any hidden fees?

Commission transparency builds trust and ensures Best Interests Duty compliance. Australian brokers typically receive lender-paid commissions rather than borrower fees.

Standard remuneration structure:

Example on $600,000 loan:

• Upfront: $3,900 (0.65%)
• Annual trail: $1,200 (0.20%)
• 5-year total: $9,900

Critical transparency questions:

• Do you charge any direct broker fees? (Most charge $0)
• What commission percentages vary between lenders?
• Do volume bonuses influence recommendations?
• Will I receive written commission disclosure before application?

Red flags:

• Refusing to disclose commission rates
• Pushing one lender without comparison
• Mentioning “preferred partners” without justification
• Charging fees above $500 without clear value

Secured Nest operates on lender-paid commission (no borrower fees for standard applications) with written disclosure provided within 24 hours of consultation.

Question 4: How will you calculate my borrowing capacity in today’s market?

Borrowing capacity determines maximum loan approval based on income, expenses, debts, and APRA’s 3% serviceability buffer.

APRA requirements in 2026:

• Serviceability buffer: 3% above application rate (6.5% assessed at 9.5%)
• Debt-to-income monitoring: Lenders face restrictions on loans exceeding 6× income
• Living expenses: HEM (Household Expenditure Measure) or actual, whichever higher
• Credit commitments: Full card limits counted, not just balances

Capacity calculation example:

At 9.5% serviceability rate: Borrowing capacity approximately $830,000

Strategies to increase capacity:

• Reduce credit card limits ($15,000 card = $50,000-$70,000 capacity increase)
• Pay off small debts before application
• Include all income sources (bonuses, overtime, rental income at 80%)
• Declare accurate expenses (understating causes decline)

Questions to ask:

• What serviceability buffer do different lenders apply?
• How do lenders treat my rental income?
• Can you model scenarios to maximize borrowing power?

Secured Nest uses proprietary calculators updated monthly, modeling scenarios across 15+ lenders to identify optimal borrowing capacity.

Question 5: Can you help me avoid Lenders Mortgage Insurance (LMI)?

Lenders Mortgage Insurance protects lenders when borrowing above 80% LVR, costing $10,000-$30,000+ on deposits below 20%.

LMI cost breakdown:

LMI avoidance strategies:

1. First Home Guarantee Scheme: Government guarantees 15%, enabling 5% deposit with no LMI (35,000 places annually)
2. Family Guarantee: Parents use property equity as security (no LMI at 90-95% LVR)
3. Professional Discounts: Medical professionals access LMI waivers to 90% LVR
4. Save 20% Deposit: Standard LMI threshold avoidance
5. First Home Super Saver Scheme: Withdraw up to $50,000 from super

Cost comparison on $700,000 purchase:

Critical questions:

• Which lenders offer lowest LMI premiums?

• Am I eligible for First Home Guarantee?

• Can my occupation qualify for LMI waivers?

Secured Nest maintains relationships with all First Home Guarantee Scheme lenders and processes Family Guarantee structures across 8 major lenders.

Question 6: Should I choose a Fixed or Variable rate for 2026?

Interest rate structure impacts monthly repayments, flexibility, and total interest paid.

Current rates (February 2026):

Choose Fixed if:

• Budget certainty required (tight cash flow)
• Rate rises expected within fixing period
• Not refinancing within 2-3 years
• Limited offset account usage

Choose Variable if:

• Planning extra repayments above minimum
• Maintain $20,000+ savings for offset
• May refinance or sell within 2-3 years
• Rate falls expected (RBA predicted 3.85% by December 2026)

Split loan strategy: 50/50 or 60/40 between fixed and variable provides partial protection plus flexibility.

Break costs warning: Exiting fixed loans early costs $3,000-$18,000 per $100,000 depending on remaining term and rate movements.

Secured Nest provides monthly rate outlook reports comparing fixed vs. variable scenarios with projected interest savings.

Question 7: What loan features (Offset/Redraw) do I actually need?

Loan features significantly impact interest paid and repayment flexibility.

Offset account mechanics: $30,000 balance on $500,000 loan at 6.5% saves $1,944 annually in interest.

Offset vs. Redraw:

Who needs offset:

• Maintain regular savings ($10,000+)
• Receive irregular income (bonuses, commissions)
• Operate business accounts
• Invest in property (preserves deductibility)

Who suits redraw:

• Minimal savings ($0-$5,000)
• Prefer basic loan structure
• Unwilling to pay $200-$395 annual fee

Other valuable features:

• Unlimited extra repayments: $200 extra monthly saves $100,000+ interest over 30 years
• Split loan facility: Divide loan between fixed/variable
• Portable loans: Transfer to new property without refinancing

Secured Nest evaluates features against actual banking behavior, calculating precise interest savings versus annual fees.

Question 8: How long will my pre-approval take?

Pre-approval timelines vary from 24 hours to 4 weeks depending on lender and application complexity.

Average processing times:

Factors affecting speed:

Fast-track (24-48 hours):

• PAYG employment 2+ years
• Strong credit score (700+)
• 20%+ deposit from genuine savings
• Clean bank statements

Extended processing (14-28 days):

• Self-employed (requires 2 years’ tax returns)
• Temporary visa holders
• High LVR (85-95%)
• Recent credit defaults

Pre-approval validity:

• Standard: 90 days
• Rate lock: 90 days typically
• Requires updated documents if expired

Secured Nest lodges to lenders with fastest processing for your scenario and monitors applications daily.

Question 9: What is my Debt-to-Income (DTI) ratio?

Debt-to-income ratio measures total debt against gross income. APRA monitors DTI ratios, restricting loans above 6× income.

DTI calculation: Total Debt ÷ Gross Annual Income

Example:

Strategies to improve DTI:

• Pay off credit cards before applying
• Close unused credit accounts (limits count at $0 balance)
• Include partner’s income if applying jointly
• Increase deposit size (reduces loan required)

Questions to ask:

• What’s my current DTI and how does it affect approval?
• Do any lenders accept higher DTI ratios?
• Should I pay off debts before or after application?

Secured Nest calculates DTI during initial consultation and develops debt optimization strategies if exceeding 6×.

Question 10: Will you review my rate after settlement?

Ongoing rate reviews determine whether your mortgage remains competitive. Lenders increase rates for existing customers 0.20%-0.60% above new borrower rates—the “loyalty tax.”

Loyalty tax costs:

Refinancing example:

• Current: $480,000 at 6.79%
• Refinance: $480,000 at 6.19%
• Monthly saving: $190
• Annual saving: $2,280
• 5-year saving: $11,400 (after costs)

When to refinance: 

• Rate difference exceeds 0.30% 
• Loan balance above $250,000 
• 2+ years until fixed rate expiry
• No break costs on current loan

Broker support includes:

• Annual rate reviews comparing your rate vs. market
• Proactive alerts when rates drop significantly
• Negotiation with existing lender for retention offers
• Cost-benefit analysis for refinancing decisions

Questions to ask:

• Do you provide annual rate reviews as standard?
• What’s your process for notifying me of better rates?
• Will you negotiate with my lender before recommending refinance?

Secured Nest provides automated annual reviews with personalized comparison reports, maintaining a 23-month average refinancing cycle versus industry average 7+ years.
