Thousands of homeowners are paying higher interest rates on their mortgages than they need to - but many may not realise it.
Herald on Sunday inquiries reveal that although thousands of borrowers, particularly in Auckland, have accumulated enough equity to entitle them to better interest rates, many don't know it.
It comes after the release of new CVs in Auckland, showing average property value increases of 29 per cent across the city from 2011-2014.
That means the bulk of borrowers who bought property with a small deposit in those years will now have equity of at least 20 per cent, entitling them to better interest rate deals.
Banks are competing for borrowers with more equity because loan-to-value restrictions limit the amount of low-deposit lending they can do. They offer special fixed rates and sweeteners such as cash contributions to those with 20 per cent equity.
