How much can I borrow?
Before lending to you, lenders will calculate your serviceability and loan-to-value ratio (LVR).
Serviceability refers to your ability to repay your loan. While each lender uses a slightly different method to calculate serviceability, all rely on factors like your income, expenses and level of debt.
As a basic calculation, lenders will add your net income, subtract your living expenses and debt, and use the balance to determine whether you can afford your home loan repayments. Lenders may also add an interest rate buffer to their assessment to ensure that you can service the loan even if interest rates go high in the future. After all, the rates will almost certainly rise and fall during your mortgage.
Your deposit is an important part of this calculation, and lenders will use your deposit amount to determine your loan-to-value ratio (LVR). LVR is calculated by dividing the amount of the loan (less your deposit amount) by the value of the property expressed as a percentage.
For home buyers, an LVR of 80 per cent is usually required, which means you need to have 20 per cent of the property’s value saved as a deposit. (Other deposit options are available to first-home buyers who don’t have a 20 per cent deposit saved up, so don’t despair if you’re struggling to reach that magic number!)
For example, if the property is worth $500,000 and you have a deposit of $100,000, your LVR is 80 per cent ($500,000 less $100,000 divided by $500,000).
While it is still possible to buy a first home with a lower deposit, LVR restrictions imposed by the Reserve Bank of New Zealand can mean lenders are limited in the amount of high LVR lending they can do. They may also charge additional fees for high LVR lending, like Lenders’ Mortgage Insurance (LMI). LMI is a set dollar amount or a percentage of your loan amount that lenders charge as insurance to protect themselves against potential mortgage defaults.
