The read

Owner-occupier stronghold

85% of homes here are owner-occupied and 13% rented, with 5% of landlords negatively geared.

Why it fits

85% owner-occupied — owner-occupiers hold longer and absorb rate shocks, supporting price stability.

What to check

Gross yield 2.1% is thin — returns here lean on capital growth, not cash flow.

ABS Census 2021 tenure (G37), ATO postcode rental statistics, and QuickProperty's investor-exposure index. Owner-occupied = owned outright + with a mortgage.
