Deagon is a smaller community of 3,773 — about 69% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. Household income of $83,460/year is 8% below the Queensland median of $90,298, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Rent of $350/week (82% coverage of the $1,846/month median mortgage) leaves a gap of roughly $329/month that a typical investor bridges with negative gearing, depreciation and capital growth. 16 km from Brisbane places Deagon in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs.
This suburb suits long-term investors looking for a balance of rental yield and capital growth. Schools and transport underpin family demand. Local rents consume roughly 22% of household income — a useful sanity check on tenant affordability.

Deagon has a usual resident population of approximately 3,773, compared with a Queensland suburb median of 5,474 — placing it in the lower half of the state's suburbs by size.

The median monthly mortgage repayment in Deagon is $1,846, or approximately $22,152/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 $350 works out to $1,517/month, covering 82% of the median mortgage repayment of $1,846/month. That leaves a $329/month shortfall (around $3,948/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 a thin buyer pool (3,773 residents), interest-rate sensitivity on the $1,846 median mortgage, the broader Queensland market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
