What are Debt-to-Income (DTI) restrictions?

 

DTI restrictions are a tool used by regulators globally to limit the amount of debt that borrowers can take on, relative to their income.

 

In New Zealand, the RBNZ is considering introducing DTI restrictions to help reduce the risk of a housing market crash caused by a surge in highly indebted borrowers defaulting on their mortgages.

 

The RBNZ has not put forward a DTI ratio yet, but it is expected to be between 5 and 7. If they settled on a ratio of 6 then this means that borrowers' total debt should not exceed 6 times their income.

 

 

What is counted as income under the rules?

 

When calculating the DTI ratio, the RBNZ includes all income that a borrower receives from employment, self-employment, investments (including rental income), and any other sources.

 

The RBNZ may also take into account any expected changes in a borrower's income, such as job loss or retirement. In general, lenders will be required to take a prudent approach when assessing a borrower's income and expenses, taking into account factors such as the borrower's ability to meet their ongoing expenses and the risks associated with the loan.

 

 

When are DTI restrictions likely to be introduced?

 

The RBNZ is not in a huge rush to bring the rules in, given the current soft nature of the property market.

 

They have signaled that we are likely 12 months away from their introduction.

 

 

Are there any exemptions that might apply to Property Investors?


Yes.

 

Construction loans will likely be exempt so if you are borrowing to build an investment property then that loan could be exempt from DTI rules.

 

Similarly, a loan used to purchase a ‘new build’ would likely be exempt.

 

 

What impact will DTI restrictions have on Property Investors?

 

If you look at the below chart published by the RBNZ, you can see that Investors typically have higher DTI ratios than other buyer types, so we can expect that investors will feel the impact of DTI restrictions more than most.

One potential negative impact, highlighted by the New Zealand Property Investors Federation, from DTI restrictions is rising rents due to a smaller supply of rental properties.

 

 

It is worth noting that these rules are currently proposed, and may be subject to change depending on the outcome of the consultation process.

 

However, they provide some indication of the RBNZ's thinking on the issue of DTI restrictions, and suggest that the rules are likely to be nuanced and targeted to ensure that they do not have unintended consequences.
