APPENDIX 1 HOUSING COST MEASURES
Interest and principal components
In 2009-10 interest accounted for 64% of total mortgage repayments for owners with a mortgage. For first home buyers and changeover buyers with a mortgage (households that had purchased their home in the three years prior to interview), interest on the loan accounted for 71% and 73% of total mortgage repayments respectively. This is because a greater proportion of the repayment is typically applied to interest at the beginning of a loan amortisation schedule, while a greater proportion is applied to principal at the end.
Proportion of loan used for housing purposes
The housing costs reported in this publication only include mortgage repayments if the main purpose of the loan was to buy, build, add to or alter the occupied dwelling. For example, if a loan was taken out primarily to buy a dwelling, but part of it was used to purchase a car, the entire repayment amount is included in housing costs. Similarly, if a loan is taken out primarily for other purposes, but is partly used for housing purposes, the repayments are not included in housing costs. From the 2003-04 SIH, where a loan had multiple purposes, details of all purposes were collected, so repayments could be allocated to each purpose, in accordance with the percentage split of the original loan amount by purpose.
Data from the 2009-10 SIH indicates that, if mortgage repayments were calculated in accordance with the proportion of the loan used for housing purposes, the housing related mortgage repayments of owners with a mortgage would be 2% lower than if calculated according to the main purpose of the loan.
Repairs, maintenance and dwelling insurance
Measures of housing costs could also include other outlays that have not been collected in the 2009-10 or earlier SIHs, but which are necessary to ensure that the dwelling can continue to provide an appropriate level of housing services. These include repairs, maintenance and dwelling insurance, and are costs that tend to be incurred by owner occupier households, but not directly by renting households. Expenditure data on each of these components is collected in the Household Expenditure Survey (HES). The 2009-10 HES was conducted on a subsample of households in the 2009-10 SIH.
Data from the 2009-10 HES indicates that if these costs were added to the SIH housing cost measures, the estimates of average housing costs would increase by $42 per week for owners without a mortgage, and by $52 per week for owners with a mortgage (in 2009-10 dollars).
For the first time, the 2009-10 SIH collected outlays for repairs, maintenance and dwelling insurance, enabling broader measures of housing costs to be produced from the survey.
The ABS has taken a number of steps to improve the coverage, quality and usefulness of data for analyses of the housing costs of renter households.
Housing costs for renter households in this publication comprises rent payments plus any rates payments that were paid by the household (general and water). The measure does not take into account any refunds from a business or person outside of the household, or any Commonwealth Rent Assistance (CRA) payments received.
In 2003-04 the ABS commenced collecting extra information on the housing costs of renters, including payments for water consumption and amounts refunded by a business or someone outside the household. In 2007-08 the ABS commenced collecting information on whether persons and income units are currently in receipt of CRA and the amount that they receive.
Commonwealth Rent Assistance (CRA)
Some households renting in the private rental market are reimbursed some or all of their housing costs in the form of CRA. CRA is a non-taxable income supplement paid through Centrelink to qualifying recipients of income support payments and family tax benefit, and is paid in conjunction with that other benefit. In this publication these reimbursements are neither offset from the housing costs nor deducted from income of the principal tenant when comparing tenure types. Where one income unit within a household receives CRA and sub-lets from another household member, CRA should be deducted from the income of the recipient of this government payment and added to the income of the primary tenant. While this does not change total household income it does affect analysis of the economic wellbeing of income units within the household.
While CRA receipts were collected in the 2009-10 SIH, and used in some reporting for lower income households, the ABS is undertaking further investigation into more comprehensive use of CRA data in reporting results from this survey.
TOWARDS A MORE COMPREHENSIVE MEASURE
Ideally, a more comprehensive measure of housing costs should take into account the issues discussed above. Housing costs could then be more meaningfully compared across all tenure and landlord types. A fuller measure might also include body corporate payments.
Table 4 presents an alternative measure of housing costs to that generally included in this publication. It shows housing costs after adding body corporate payments, repairs, maintenance and dwelling insurance. It also includes housing related mortgage repayments on a pro-rata basis and excludes the interest component of mortgage repayments. Amounts refunded by a business or someone outside of the household are also excluded (but no adjustment has been made for CRA payments).
Data from the 2009-10 SIH, and the 2009-10 HES, indicates that, if this alternative measure was used, the estimates of average housing costs included in this publication would:
