AI summary

A revolving credit mortgage treats part of your home loan like a large overdraft. It offers flexibility by letting you deposit funds to reduce interest and potentially pay your mortgage off faster, while still allowing you to withdraw that money if needed.

However, this structure requires strong financial discipline to avoid overspending. Revolving credit portions also typically have higher variable interest rates than standard fixed-rate loans, making them potentially more expensive if not managed well.

Consult a mortgage broker to see if this is right for you.
