How to Use
  1. Select your current lender
  2. Enter your current rate and loan details
  3. Get competitor rates and negotiation script
  4. Call your bank's retention team
Pro Tips
  • Call the 'retention team' or 'home loan review team' - they have more authority than regular staff
  • Have specific competitor offers ready - saying 'ING is offering 5.99%' is more powerful than 'I want a better rate'
  • Mention you're 'considering refinancing' - this triggers retention protocols
  • If the first person says no, politely ask to escalate - managers have more discretion
Avoid These Mistakes
  • Being aggressive or threatening - it doesn't work as well as being polite but firm
  • Not having specific competitor rates to quote - vague requests get vague responses
  • Accepting the first offer - there's usually more room, especially for loyal customers
  • Negotiating at busy times (Monday mornings, end of month) - staff are rushed
