  • Is it expensive to live in Happy Valley?

    On these figures for Happy Valley, housing looks stretched against what a typical local household earned at the last Census. A house rent of $650 a week would take about 41.3% of a typical local household's weekly income at the last Census, a large share. The median house price of $900,000 works out to about 11.0 times a typical local annual household income at the last Census, which sits well above local incomes.

    If you're renting rather than buying, that rent share is the immediate number that matters; if you're buying, the price multiple is the clearer signal. Whether that feels expensive depends on your own income and circumstances.

    Everyone's financial situation is different, so it's important to consider your own circumstances when deciding which suburb is right for you.
