Limited buy-and-hold upside: a small population of 16 means liquidity is thin and capital growth tends to lag the wider Western Australia market over full cycles.
Gross rent of $150/week (~$7,800/year) sets the yield ceiling. Cross-check against your purchase price to confirm whether this suburb hits the 4–5% gross yield most Australian investors target.
