With 13,088 residents, Mermaid Waters is one of Queensland's more populous suburbs — roughly 2.4× the state median of 5,474 — giving it a deep buyer and tenant pool that typically supports higher transaction volumes and shorter average days on market. At $91,832/year, household income in Mermaid Waters is within 2% of the Queensland median ($90,298), placing the suburb firmly in the state's mainstream demographic band. Median weekly rent of $450 equates to $1,950/month — about 90% of the median mortgage repayment of $2,167/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. Mermaid Waters is 75 km from Brisbane, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 55% of dwellings are separate houses (vs 77% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.
Coastal markets benefit from lifestyle appeal but require a buffer for higher insurance and occasional weather-driven vacancies. Local rents consume roughly 25% of household income — a useful sanity check on tenant affordability.

The median monthly mortgage repayment in Mermaid Waters is $2,167, or approximately $26,004/year (vs $1,733/month state median). Stress-test your own borrowing at rates 1–2 percentage points above today's to make sure you can still service the loan through an RBA tightening cycle.
A median weekly rent of $450 works out to $1,950/month, covering 90% of the median mortgage repayment of $2,167/month. That leaves a $217/month shortfall (around $2,604/year before tax benefits), so a typical owner-occupier-priced property here is negatively geared. Actual cash flow depends on your deposit, loan terms, ownership costs and marginal tax rate — run the full numbers in our rental yield calculator.
