Marengo is a smaller community of 8 — about 0% of the New South Wales suburb median (5,325) — so investors should factor in the narrower buyer pool and longer average time-on-market. Marengo's median household income of $64,948/year is 33% below the New South Wales suburb median ($97,552) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. Marengo is 430 km from Sydney, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.
