Mortgage calculators

Basically, banks won't lend the full amount for a house - you need to be able to put down a deposit, and the more the better. You may be familiar with 20% as the magic number, but the reality is if you're in a strong financial position we can work with as little as 5% deposit. Most people will need around 10% deposit, and if you can fork out a whopping 20%, you'll access the banks' most competitive rates and avoid low equity fees. 

The banks' appetite for lending more than 80% has been increasing recently which is excellent for first home buyers. In January 2018 the RBNZ (Reserve Bank of New Zealand) loosened their rules, and then again in January 2019 to allow 20% of total lending for owner-occupied houses with less than a 20% deposit.

If you're eager to put down a 20% deposit but don't have enough, the easiest and cheapest way is to use your parents to guarantee that part of your 20% deposit you don’t have.

Their guaranteed portion will be secured over their property or it can be secured over a term deposit, so you're not asking them to fork out cash, it's more like putting a 'hold' on their existing equity until you've paid that portion back.

In the event they use a term deposit as security, the term deposit stays in your parent’s name and they continue to earn interest on it. Guaranteed home loans are treated the same as loans under 80% so you get great interest rates, there are no fees, and you’ll even get a cash contribution from the bank. This option can potentially save you thousands. Using a guarantor makes strong financial sense, even if you can go it alone.

When the banks look at your affordability, they factor in your UMI (uncommitted monthly income) to make sure you’re left with enough to live after all your bills go out. The amount they assume varies between lenders and also depends on the loan-to-value-ratio (LVR), but aim for $300 per adult at the very least. You'll also get asked for three months’ worth of bank statements as part of the loan application, to see what your spending habits are like.

You’d be amazed at how much more you can afford to borrow if you reduce your monthly expenses. Things like Netflix, Spotify, gym memberships and consumer finance bills all add up, reducing the amount you can borrow. For example, $100 of subscriptions per month equates to a reduction of about $18,000 in borrowing power. It might be time to kick something to the curb.

Banks will test your affordability using a higher test rate, compared to current interest rates. This might seem daunting with rising interest rates, but it’s a great way for you to make sure that you don’t run into any nasty problems with repayments if interest rates increase. Our calculator above has got your back, and already factors in the banks’ testing rates.
