Revolving credit is one of the most misunderstood mortgage tools in New Zealand. Many homeowners assume it’s risky, expensive, or only suited to ultra-disciplined borrowers. In reality, when structured correctly, revolving credit can act like a powerful financial buffer – reducing interest costs daily and potentially shaving years off your home loan. This video breaks down how revolving credit actually works and whether it deserves a place in your mortgage strategy.
In this episode, we unpack revolving credit in simple terms – explaining how it functions like a large overdraft, why it’s usually paired with a fixed loan, and how it can outperform traditional savings accounts through interest savings alone. Using real numbers, we demonstrate how directing surplus income into a revolving credit facility can accelerate mortgage repayment while maintaining flexibility. We also cover the risks, including overextending your limit and poor cash management, and outline who this structure is best suited for. If used correctly, revolving credit can be a flexible, high-impact tool; used poorly, it can cost you.
