This is only if they are buying an existing property. New Builds don’t have to follow these new rules.

So if Jen wants to buy a New Build, these calculations don’t impact her. She just follows the current rules.

Want to see how the new rules impact you? I built a calculator so you can run your own numbers.

Investors need a lower deposit to buy properties

But wait, there’s more. The deposits are also changing.

Instead of needing a 35% deposit, you’ll soon only need a 30% deposit.

You might think: “That’s not a big difference”.

But renovation investors get a double whammy. Not only do you need a lower deposit, but you can also borrow more against your current properties.

Let’s say you have an investment property worth $1 million and a $550k mortgage.

Right now, you can borrow an extra $100k against this property.

Use that money as a 35% deposit; you can afford another (existing) property worth $287k.

Can’t do much with that.

What happens when the rules change?

You can now borrow $150k against your current investment property. Use that as a 30% deposit, and you can buy something worth $500k.

That’s right; you can afford a property worth 75% more.

The numbers don’t work out this way for everyone. But, some investors will soon find they can now afford an investment property when they couldn’t before.

Buying a New Build? Nothing changes. You still only need a 20% deposit.

When do all these new rules come in?

Probably June – July this year.

The Reserve Bank is consulting on these proposed rules. So banks (and any Kiwi) can make a submission.

They’ll make a final announcement in June this year.

What’s the impact on the property market?

At the start, these rules will boost house prices. Here’s why.

The new DTI rules will have almost no impact once implemented.

That’s because up to 20% of bank mortgages can be outside the rules.

So, around 1 in 5 investors and owner occupiers can get a “high DTI” mortgage.

But, interest rates are high. So it’s hard to borrow a lot of money right now.

Today, only 1 in 10 borrowers are getting these high debt-to-income loans.

That means banks could dole out even more high DTI loans and be within the Reserve Banks' new rules.

So, the DTIs won’t have an impact straight away. But the deposit changes will.

They'll encourage investors to get into the market, which could boost property prices.

Once interest rates fall, though, that’s where the DTIs come in.

We won’t be able to borrow as much as we otherwise could.

What’s the impact? It depends on where you live.

In parts of NZ (Invercargill, Taranaki), house prices are low, and incomes are healthy.

The average person buying the average home has a DTI less than 4. So the DTI rules will have less of an impact on the market.

In holiday hotspots (Queenstown and Coromandel), house prices are high compared to incomes. So, there is more scope for DTIs to slow the market down.

Here’s a map of the country, so you can see the estimated DTI in your area:
