A 20% deposit is the usual benchmark, but it is not your only option. Some lenders may consider applications with a 10% deposit, while eligible first-home buyers may be able to purchase with 5% through a Kāinga Ora First Home Loan. Construction loans and some newly completed homes may also be treated differently under LVR rules. LVR means loan-to-value ratio: it compares the amount you are borrowing with the property's value.
For example, borrowing $800,000 for a $1 million property gives you an 80% LVR, which means you have a 20% deposit or equity. Your options depend on both the size of your deposit and where it comes from, including savings, KiwiSaver, a gift or equity in another property.
