At $103,844/year, household income in Bertram is within 4% of the Western Australia median ($99,736), placing the suburb firmly in the state's mainstream demographic band. Median weekly rent of $350 equates to $1,517/month — about 90% of the median mortgage repayment of $1,686/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits.

The median monthly mortgage repayment in Bertram is $1,686, or approximately $20,232/year (vs $1,902/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 $350 works out to $1,517/month, covering 90% of the median mortgage repayment of $1,686/month. That leaves a $169/month shortfall (around $2,028/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.
