Housing costs and housing quality
Ongoing housing costs relative to income
·High outgoings for housing costs relative to income are often associated with financial stress for low- to middle-income households. Low-income households especially can be left with insufficient income to meet other basic needs such as food, clothing, basic household operations, transport, medical care and education for household members.
·Housing affordability can be measured in a number of ways. From the perspective of potential homeowners, the simplest measure is the ratio of average house price to annual household disposable income, which in effect gives the number of years needed to cover the purchase price of a house (on average). Other more sophisticated measures incorporate the cost of financing as well (eg Massey University’s Home Affordability Index). The recently released Housing Affordability Measure from the Ministry of Building Innovation and Employment uses a mix of administrative and survey data and covers both renters and aspiring first-home buyers. It is based on the notion of ‘residual income’ for households, very similar to this report’s income after deducting housing costs (AHC) measures.
·This section on housing affordability takes the perspective of households already in their own homes or renting, and uses a measure which is relevant to both homeowners and renters. The ratio used is that of gross housing costs to household disposable income, in much the same way that home-loan lenders do for assessing risk. Housing costs are taken as rates, mortgage and rent. The ratio is called OTI for short (outgoings-to-income ratio).
