5,507 residents places Dayton squarely in the middle of the Western Australia suburb size distribution (state median 5,605), with market depth comparable to most WA localities. Households here earn $110,916/year on average — 11% above the WA suburb median of $99,736 — a modest premium that supports resilient owner-occupier demand. Rent of $360/week (78% coverage of the $2,000/month median mortgage) leaves a gap of roughly $440/month that a typical investor bridges with negative gearing, depreciation and capital growth. 15 km from Perth places Dayton 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 17% of household income — a useful sanity check on tenant affordability.

A dwelling mix skewed to houses (92% vs 79% WA median) combined with a population of 5,507 creates a deeper market for value-add renovations — older stock, separate titles and stronger buyer competition are the usual pattern here.

Whether it fits your portfolio depends on whether you are targeting cash flow, capital growth, or a value-add renovation — all three are scored with suburb-specific numbers elsewhere on this page.
The main demand drivers in Dayton are proximity to Perth (15 km), an above-state-median household income of $110,916/year, a dwelling mix that is 92% separate houses, roughly 1 schools and 2 parks within the catchment. Together these shape both owner-occupier and tenant demand and are the factors we weight most heavily in the suburb's investment score.
Dayton has a usual resident population of approximately 5,507, compared with a Western Australia suburb median of 5,605 — placing it in the lower half of the state's suburbs by size. Population is the clearest proxy for market depth: more residents mean more transactions and typically a shorter average days-on-market on resale.
Dayton sits 15 km straight-line from the Perth CBD. This is comfortable commuter territory, with reasonable rail and road access to the city.
The most recent census recorded a median weekly rent of $360 in Dayton, equating to approximately $18,720/year in gross rental income (state median $350/week). Market rents have typically drifted above the recorded figure — verify against current listings on realestate.com.au and Domain before making an offer.
The median monthly mortgage repayment in Dayton is $2,000, or approximately $24,000/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 $360 works out to $1,560/month, covering 78% of the median mortgage repayment of $2,000/month. That leaves a $440/month shortfall (around $5,280/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 $2,000 median mortgage, the broader Western Australia market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
