How the savings work: Your mortgage stays mostly on a fixed rate. A $50k revolving portion is broken out. Your salary channels through it, and your monthly surplus of $0 (after expenses and fixed repayment) pays it down fast. Once cleared, another chunk is broken out from fixed. Repeat until mortgage-free.

How does channeling work?

1
Keep the bulk on fixed
Most of your mortgage stays on a fixed rate for security and predictability.
2
Break out a revolving chunk
A smaller portion (e.g. $50k) is moved into a revolving credit facility linked to your everyday account.
3
Channel your salary through it
Your income goes straight into the revolving credit, reducing the balance daily. Bills and expenses come out as normal. The gap between income and spending pays it down fast.
4
Clear it, then break out more
Once the revolving chunk is paid off, break out another chunk from your fixed loan. Repeat until you're mortgage-free — years ahead of schedule.
