Coomba Bay is a smaller community of 168 — about 3% of the New South Wales suburb median (5,325) — so investors should factor in the narrower buyer pool and longer average time-on-market. Household income of $82,316/year is 16% below the New South Wales median of $97,552, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Median weekly rent of $400 equates to $1,733/month — about 114% of the median mortgage repayment of $1,517/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. Coomba Bay is 212 km from Sydney, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
