Why Lenders Lower Rates for Existing Customers
Banks are not in the business of giving money away — but they're also not in the business of losing established customers to competitors. The economics are simple:
- Acquiring a new mortgage customer costs a bank approximately $3,000–$5,000 in marketing, commission, and processing
- Retaining an existing customer costs a 0.3% rate discount — which on a $500,000 loan is $1,500/year
- The bank still earns more keeping you than replacing you, even after the discount
This is why banks have retention teams — dedicated staff with pricing authority whose sole job is to keep customers from leaving.
Your Leverage — What Actually Moves the Needle
| Leverage Factor | Strength | How to Use It |
|---|---|---|
| Genuine competitor offer (in writing) | Very strong | "I have a written offer from [Lender X] at [rate]. I'd prefer to stay but I need you to match or beat it." |
| Low LVR (below 60%) | Strong | "My current LVR is under 60% — I'm low-risk and deserve your best rate." |
| Long, clean repayment history | Medium-strong | "I've been a customer for X years and never missed a payment." |
| High income / stable employment | Medium | Mention if relevant — reduces perceived risk |
| Loyalty (multiple products) | Medium | "I have my transaction account, savings, and home loan with you." |
| Willingness to switch (not bluffing) | Strong | The conversation must be genuine — if they say no, you follow through |
The Exact Script to Use
Opening the call:
"Hi, I'd like to speak with someone from your home loan retention team please — not general customer service, but specifically the retention team."
Once connected:
"I've been a [Bank X] customer for [X] years with a [loan balance] home loan. I've recently been reviewing my options and I've received an offer from [Competitor Lender] at [rate]%. I'd prefer to stay with [Bank X] rather than go through the process of switching — but I need you to offer me a rate that's competitive. Can you tell me what your best available rate is for a customer with my profile?"
If they offer a discount but not enough:
"I appreciate that. The competitor offer I have is [X]%. That's [Y]% below what you've just offered. Is there anything more you can do? I'd genuinely prefer not to refinance."
If they won't budge:
"Understood. I'll need to think about whether it makes sense to stay. Can I speak with a supervisor or get this in writing so I can compare? I'll let you know my decision within a few days."
Typical Savings from Negotiation
| Loan Balance | 0.2% Discount | 0.35% Discount | 0.5% Discount |
|---|---|---|---|
| $400,000 | $800/year | $1,400/year | $2,000/year |
| $500,000 | $1,000/year | $1,750/year | $2,500/year |
| $600,000 | $1,200/year | $2,100/year | $3,000/year |
| $750,000 | $1,500/year | $2,625/year | $3,750/year |
| $1,000,000 | $2,000/year | $3,500/year | $5,000/year |
Retention Discount vs Cashback: Which Is Better?
| Option | Upfront Value | Ongoing Value | Conditions | Best When |
|---|---|---|---|---|
| Rate discount from current lender | None | $1,000–$5,000/year ongoing | Rate may drift back over time | Plan to stay 3+ years |
| Cashback from new lender | $2,000–$4,000 once | Potentially lower rate ongoing too | Clawback period 2–3 years | Rate also lower + you won't switch again soon |
When Refinancing Beats Negotiating
Negotiating your rate is always the first step — it costs nothing and takes one phone call. But there are scenarios where refinancing is clearly better:
- The market rate gap is more than 0.4% and your lender won't match it
- You want features your current lender doesn't offer (e.g., offset account on a fixed loan)
- There's a cashback offer that outweighs switching costs after break-even calculation
- You want to consolidate debts and your current lender won't do cash-out refinancing
- Your fixed rate is expiring and the best deal is elsewhere
How Often to Review
Review your rate at minimum once per year, and immediately whenever:
- The RBA changes the cash rate (your lender may not pass it fully)
- You see a competitor advertise a rate more than 0.3% below yours
- Your LVR crosses below a threshold (80%, 70%, 60%) due to repayments or property value growth
- Your income has increased significantly (stronger serviceability)
