Blackwood SA Investment Brief

## 1. Investment Verdict Buy – Blackwood scores 72.0/100 on our investment scorecard. The single most important number is the 0.8% vacancy rate. That signals extreme rental demand and minimal holding risk for investors.

## 2. Market Overview Blackwood’s median house price sits at $1,290,000, with units at $630,500. The 1-year price growth of 12.5% shows strong momentum, though the market cycle is currently cooling. Over 5 years, the compound annual growth rate is 4.4% per year, delivering steady capital appreciation. Days on market data is unavailable, but the cooling cycle suggests buyers have slightly more negotiating power now than six months ago. For sellers, the 12.5% annual gain still favours listing, but patience may be required.

## 3. Rental Market The vacancy rate is 0.8% – extremely tight. Median weekly rent is $700, producing a gross rental yield of 2.8%. Rental demand is rated very high, and the vacancy trend is improving. For investors, this means near-zero vacancy risk. The 2.8% yield is below the 3-4% benchmark for Adelaide suburbs, but the capital growth potential offsets this. Owner-occupiers make up 89% of the population, which stabilises the market during downturns.

## 4. Short-Term Rental Opportunity The median nightly STR rate is $462, with occupancy at 42%. Estimated annual revenue: $462 x 0.42 x 365 = $70,800. Compare that to long-term rental income of $700 x 52 = $36,400. STR generates nearly double the gross income. However, the 42% occupancy rate is low – below the 55-60% average for Adelaide. This suggests seasonal demand or oversupply of STR listings. For most investors, LTR is the safer bet given the 0.8% vacancy rate and lower management complexity.

## 5. Infrastructure & Growth Drivers Two major projects are driving demand. The North South Corridor (under construction) will improve road connectivity to Adelaide’s CBD, reducing commute times. The Adelaide Metro Train Services Franchise (under delivery) upgrades rail services. Blackwood station is 0.3km from the suburb centre, giving residents direct train access to the city. The employment base is diversified, with unemployment at 3.3% – well below the national average. The supply pipeline is low, meaning price growth is outpacing new construction. Limited development pipeline supports future price increases.

## 6. Bull Case If current conditions hold, Blackwood delivers strong capital growth. The 3-year growth forecast is 13.5%, which would push the median house price to approximately $1,464,000 by 2027. Combined with the 2.8% rental yield, total annualised return would be around 7.3% (4.5% capital growth + 2.8% yield). The North South Corridor completion could accelerate growth further, potentially lifting the 5-year CAGR from 4.4% to 5-6%. Low supply pipeline means any demand increase directly pushes prices higher.

## 7. Risks Three specific risks apply. First, the 2.8% gross yield is low – if interest rates stay above 6%, the property may be negatively geared by $15,000-$20,000 per year. Second, the 89% owner-occupier rate means limited rental supply, but also limited rental demand growth – if the vacancy rate rises above 2%, rents could stagnate. Third, the cooling market cycle suggests price growth may slow to 5-7% annually over the next 12 months, below the 12.5% seen recently. No single-employer dependency or significant supply pipeline risk exists.

## 8. The Play Entry range: $1,150,000-$1,350,000 for houses, $600,000-$660,000 for units. Target minimum gross yield of 2.8% – anything below that is too thin. Watch signals: vacancy rate staying below 1.0% and the North South Corridor construction timeline. If the vacancy rate rises above 1.5%, reconsider. Recommended strategy: buy a house with land component for capital growth, hold for 5-7 years, and use the 0.8% vacancy rate to maintain near-100% occupancy. Avoid units – the yield is similar but capital growth is weaker.
