Collinswood SA Investment Brief

## 1. Investment Verdict Buy – Collinswood scores 72.0/100 on our investment scorecard, driven by a 15.8% one-year price growth and a 0.8% vacancy rate. The single most important number is the 0.8% vacancy rate – it signals extreme undersupply and landlord-friendly conditions.

## 2. Market Overview The median house price sits at $1,850,000, with units at $626,002. One-year price growth hit 15.8%, well above the 5-year CAGR of 4.9% per year. The 3-year growth forecast of 13.5% suggests continued but moderating appreciation. Days on market data is unavailable, but the 0.8% vacancy rate and 67% owner-occupier rate indicate a tight market where sellers hold pricing power. Buyers face elevated entry costs, but the stable market cycle and limited supply pipeline (scorecard: low) favour patient investors.

## 3. Rental Market The vacancy rate is 0.8% – critically low and improving. Median weekly rent is $720, generating a gross rental yield of just 2.0%. Rental demand is rated “very high” in the scorecard. For investors, the yield is below the 2.5%+ typically required for positive cash flow, but the tight vacancy and 4.0% unemployment rate support rent growth. The 67% owner-occupier rate reduces rental supply, further tightening the market.

## 4. Short-Term Rental Opportunity The median STR nightly rate is $458, with occupancy at 42%. Estimated annual STR revenue: $458 × 365 × 0.42 = $70,000. Compare this to LTR annual rent: $720 × 52 = $37,440. STR generates 87% more gross revenue, but the 42% occupancy rate suggests seasonal or event-driven demand. LTR offers stability with a 0.8% vacancy rate; STR offers higher upside but operational risk. For most investors, LTR is the safer play given the low vacancy and reliable rent growth.

## 5. Infrastructure & Growth Drivers Two major projects are underway: the Adelaide Metro Train Services Franchise (under delivery) and the North South Corridor (under construction). Dudley Park station is 2.7km away, providing rail access to Adelaide CBD (3km). The unemployment rate is 4.0%, below the national average. The low supply pipeline (scorecard: low) means price growth is outpacing new construction, limiting future competition. The 67% owner-occupier base provides stable demand.

## 6. Bull Case If conditions hold, Collinswood could see the 13.5% 3-year forecast materialise, pushing median house prices to $2.1 million by 2027. The 0.8% vacancy rate could tighten further to 0.5% as the North South Corridor completion draws more commuters. Rent growth could accelerate to 5-7% annually, lifting yields from 2.0% to 2.3% within three years. The low supply pipeline means existing stock appreciates faster than new builds.

## 7. Risks - Yield risk: 2.0% gross yield is below the 3%+ threshold for positive cash flow in most lending scenarios. A 1% rate rise could push holding costs above rent. - Vacancy risk: At 0.8%, vacancy is near-zero, but a recession (unemployment rising from 4.0% to 6.0%) could push it to 2.5%, cutting rental income. - Supply pipeline: Low now, but if zoning changes allow higher-density development, new units could flood the market, compressing yields. - Rate sensitivity: The 15.8% one-year growth is partly rate-driven. If the RBA cuts rates, prices could accelerate; if they hold, growth may slow to the 4.9% CAGR trend. - Single-employer dependency: Not identified as a risk in the scorecard, but Collinswood’s small population (1,496) means local employment is concentrated in Adelaide’s broader economy.

## 8. The Play - Entry range: $1.7M$2.0M for houses; $550K$700K for units. - Minimum yield to target: 2.5% gross yield – achievable with a $720/week rent on a $1.5M purchase, but unlikely at current median prices. Focus on units for better yield. - Watch signals: Vacancy rate above 1.5% for two consecutive quarters; unemployment above 5.0%; any major infrastructure delays. - Recommended strategy: Buy a unit near Dudley Park station for yield (2.0% vs 1.8% for houses) and hold for 5+ years. The low supply pipeline and 13.5% forecast growth support capital gains, but the 2.0% yield requires interest rate hedging. Avoid STR unless you can manage seasonal occupancy.
