  • Is it expensive to live in Thornlie?

    On these figures, buying a house in Thornlie sits well above what people locally earned at the last Census. A median house price of $917,500 is about 11.2 times a typical local household's annual income at the last Census (median weekly household income $1,571), so buying is at a high multiple of local incomes.

    Rents also take a large share of local income: a house rent of $700 a week is about 44.6% of a typical local household's weekly income at the last Census, while a unit rent of $600 a week is about 38.2% of that weekly income. If you are renting rather than buying, those rent shares are the most relevant measures; whether they feel expensive depends on your own circumstances.

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

  • Is Thornlie a good place to invest?

    The past year in Thornlie saw notably large increases in property values: median unit values rose 28.9% and median house values climbed 21.4%, both strong rises. Rents moved more slowly over the same period, with house rents up a solid 7.7% and unit rents up a more modest 2.0%.

    For someone weighing Thornlie up as an investment, the value figures point to capital growth over the year, particularly on the unit side, while the rent figures are the ones that matter if ongoing rental income is your priority — and house rents increased more than unit rents this year. Whether that balance fits your goals and circumstances is for you to decide.
