AI summary

A revolving credit mortgage makes part of your home loan act like a large overdraft. You can deposit funds to reduce your interest payments and withdraw them again, offering great flexibility.

This structure can help you pay your mortgage off faster and is ideal for renovations. However, it requires strong financial discipline and often has a higher variable interest rate than fixed-rate loans. This tool is best for disciplined savers, and seeking advice from a mortgage broker is recommended.
