AI summary

Refinancing your mortgage means getting a new loan, often with a different lender, to pay off your current one. This differs from restructuring (changing your setup with the same bank).

Kiwis often refinance to secure a lower interest rate, reduce repayments, get a cash incentive, or release home equity for other projects. Be aware of potential costs like break fees on fixed loans, lawyer fees, and repaying previous incentives. An annual mortgage review is recommended.
