The median monthly mortgage repayment in Blackburn South is $2,251, or approximately $27,012/year (vs $1,950/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 $410 works out to $1,777/month, covering 79% of the median mortgage repayment of $2,251/month. That leaves a $474/month shortfall (around $5,688/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.
The main risks are interest-rate sensitivity on the $2,251 median mortgage, the broader Victoria market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
