Is it expensive to live in Thornlie?

Buying in Thornlie sits well above local incomes. The median house price of $877,500 works out to about 10.7 times a typical local annual household income, based on a typical local household earning about $1,571 a week at the most recent Census. Renting also takes a notable share of income: a house rent of $700 a week would use about 45% of that weekly household income, while a unit rent of $600 a week would take about 38%. On these figures, buying looks markedly more stretched against local incomes, and renting would still take a sizeable to large share of a typical local household's weekly earnings; 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.
