Much has been written about the housing crisis in Auckland, and elsewhere in New Zealand, but the issue of affordable housing is not well explained. Kiwis in upper wage brackets can always afford the high prices especially when they are buying and selling on the same market. It is the first home buyers and those with lower wages who are in trouble.
"Affordable housing" is a phrase that has been used in the media in different ways. A common definition is that a house is said to be affordable if its asking price is 75 per cent of the median selling price of houses in the area. In a few months the median house price in Auckland will be a million dollars. Does that mean that a house costing $750,000 dollars is suddenly "affordable"? Likewise we are told 20 per cent of houses at Hobsonville are "affordable".
An alternative definition is that housing is affordable if the cost of housing is 40 per cent of take-home pay. Clearly what is affordable for a family depends on what they earn, so in this scenario the family income needs to be the starting point. Statistics NZ gives the median family income in Auckland for 2015 as $1575 a week. Using the IRD tax calculator and taking 3 per cent for KiwiSaver leaves $1183 take-home pay.
Taking 40 per cent of this gives $473 a week to pay the mortgage (or rent). If interest on the mortgage is 5 per cent this will sustain a mortgage of $350,000. With a 20 per cent deposit, a house costing $440,000 is therefore affordable under this definition. (Prudence suggests you should be prepared for an increase in mortgage rates to 7 per cent, meaning you should only spend $360,000 on a house.)
