For January 2012 – For immediate release
Home loan affordability improves slightly in January, but near worst in two years
Home loan affordability improved slightly in January after a fall in the national median house price, but is just above its worst levels since November 2010.
Interest rates also increased marginally, but are only just above record lows. House price inflation over most of the last year has been the driving factor in home loan affordability, and has been only partially offset by lower fixed mortgage rates linked to more intense competition between banks.
New Zealand’s median house price fell to NZ$370,000 from a record high NZ$389,000 in December, according to REINZ data, but remains up 4.2% from a year ago.
A surge in house prices in Auckland and Christchurch over the last year because of a shortage of supply is now beginning to leach out into some provincial areas where economic activity is stronger and emigration is slower.
Nationally, affordability improved by 2.6 percentage points in January from December, but remains worse than a year ago because of rising house prices. That is, it took 3.6 percentage points less of take home pay to afford the mortgage payments for a median priced house, according to the Roost home loan affordability report released today.
This means it cost $30.58 less per week in January 2012 than in December 2011 to make home loan payments on a median priced house.
“These record low interest rates and hot competition between the banks is making it easier for first home buyers and investors to buy in this market,” said Colleen Dennehy, a spokeswoman for Roost, which sponsors the Home Loan Affordability report series from Interest.co.nz.
Affordability improved in Northland, Auckland, Wellington, Canterbury and Otago, but deteriorated on Auckland’s North Shore, Hastings and Invercargill.
Average advertised floating mortgage rates rose slightly in January, but have been broadly unchanged over the last year. Advertised six month and 1 year mortgage rates have fallen over the last year.
For first home buyers – which in this Roost index are defined as a 25-29 year old who buys a first quartile home – the news is also better in January. Apart from Auckland, Queenstown and Canterbury, it takes around 20-40% of after tax pay to afford an 80% mortgage on a lower quartile priced house. That percentage rises however to 66%, 67% and 47% respectively in those three most expensive areas.
Any level over 40% is considered unaffordable, whereas any level closer to 30% has coincided with increased buyer demand in the past.
For working households, the situation is similar although bringing two incomes to the job of paying for a mortgage makes life considerably easier. A household with two incomes would typically have had to use 35.1% of their after tax pay in January to service the mortgage on a median priced house. This is down from 36.9% a year ago.
On this basis, most New Zealand cities have a household affordability index below 40% for couples in the 30-34 age group. This household is assumed to have one 5 year old child.
For households in the 25-29 age group (which is assumed to have no children), affordability also improved, with 21.8% of after tax income in households with two incomes required to service the debt, down from 22.8% the previous month.
Any level over 30% is considered unaffordable in the longer term for such a household, while any level closer to 20% is seen as attractive and coinciding with strong demand.
First home buyer household affordability is measured by calculating the proportion of after tax pay needed by two young median income earners to service an 80% home loan on a first quartile priced house.

Question and Answers about the report
How does interest.co.nz work out these numbers?
Interest.co.nz gathers data from Statistics New Zealand and IRD on wages in each region, data from the Real Estate Institute from each region each month, and data from banks and non-banks on interest rates. It has calculated home loan affordability going back to the beginning of 2002.
How is this survey different from the Massey University survey of affordability?
The Massey study is only done quarterly rather than monthly and uses an index of Home affordability rather than actually measuring home loan affordability. It uses an index rather than the actual measure of the proportion of after tax pay needed to service an 80% mortgage on a median home. The exact composition and meaning of the index is not detailed.
Why use a single median income rather than household income?
It’s true that most homebuyers are using a combination of one or more full or part time incomes to service their mortgage. Each household is different and may be using incomes from different sources. The best measure of average national household income is calculated officially once in every three years by Statistics New Zealand. Interest.co.nz chose to use the median income data series from IRD and Statistics NZ because it can be measured monthly and can be drilled down by region and by age. We do include a chart showing how many median incomes are required to keep mortgage payments at 40% of take home pay. It is currently around 2 median incomes.
Why is home loan affordability important?
It is a useful way to work out if a housing market is overvalued. It’s clear house prices stopped rising when the national affordability ratio rose above 80% or 2 median incomes to service the average home loan. It’s a way of comparing affordability of housing markets with a national average and comparing housing values from one year to the next. For example, the affordability ratio in 2002 before the housing boom really took off was around 41%.
