  • Is St Marys a good place to invest?

    The clearest story over the past 12 months in St Marys is the strength in property values: unit values jumped 19.6% and house values rose 14.7%, both strong increases. Rental moves were more modest, with house rents up 5.3% (a solid rise) and unit rents up 4.2% (a modest rise).

    Put simply, the figures show strong capital growth on both sides of the market this year while rental income rose more moderately. If rental income is your priority the rent figures are the ones to focus on, and if capital growth matters more the value movements are the relevant measure; whether that balance suits you depends on your own goals and circumstances.
