How to Negotiate a Lower Rate With Your Current Bank

—

The single most underused mortgage hack: calling your bank and asking for a lower rate. Australians who do this succeed about 70% of the time. Here’s the exact playbook.

Why It Works

Banks calculate that retaining a customer is cheaper than acquiring one. Internal “retention pricing” is almost always better than the rate you’d see advertised.

The catch: they only offer it if you ask, and only if you have leverage.

Build Leverage Before Calling

1. Get a competitor quote first. Email 2 brokers and 1 direct lender. Ask: “Given my profile (income, loan size, LVR), what’s the rate you can offer me on a refinance?”

You don’t need to actually refinance. You need a written quote to wave.

2. Know your numbers cold.

Your current interest rate
Your loan-to-value ratio (after recent valuation increase if applicable)
Your loan balance and remaining term
Your serviceability (income hasn’t dropped, no new debts)

The Call Script

Step 1 — Position

“Hi, I’ve been a customer for [N] years. I’m reviewing my mortgage and looking at competitor offers. I’d prefer to stay with you, but my current rate isn’t competitive. I’m hoping to discuss what you can do.”

Step 2 — Make the Ask

“I’ve got [Competitor X] offering me [Y%]. Can you match or beat it?”

Step 3 — Don’t Settle on First Offer Their first response is often “let me see what I can do.” Their second offer is usually 0.1–0.3% better than the first. The third is sometimes another 0.1%.

“Appreciate that, but it’s still not competitive with what’s on the table. Is there a retention team I should speak with, or someone authorized to make a more meaningful offer?”

Step 4 — Get Written Confirmation

“Please send a written confirmation of the new rate and effective date. Thank you.”

Realistic Outcomes (2026)

70% of calls: Get 0.2–0.5% reduction
20% of calls: Get 0.5–1.0% reduction (or fee waivers)
10% of calls: No movement; refinance externally

The Annual Review Strategy

Set a calendar reminder for every 12 months. Even if you got a discount last year, market changes. Call again. Re-negotiate. This single habit can save $1,500–5,000/year on a $500k+ loan.

When to Actually Refinance Externally

If your current bank won’t match a competitor offer that’s 0.3%+ better:

Calculate switching costs (~$300–500 in fees)
Compare with annual savings
If breakeven is under 12 months, switch

Mistakes to Avoid

Threatening without a real competitor offer (banks know how to call your bluff)
Negotiating during the first 12 months of a fixed rate (break costs may exceed savings)
Forgetting that bigger loans give you more negotiating power

💡 Pro Tip: Loan size matters. Banks negotiate hardest with $500k+ borrowers. If your loan is under $300k, expect smaller concessions but still ask.
