Thirroul NSW Investment Brief

## 1. Investment Verdict Buy – Thirroul scores 69.0/100 on our investment scorecard. The single most important number: 5yr CAGR of 9.0%/yr. This coastal suburb has delivered strong long-term capital growth despite a short-term dip. The market is in recovery phase, vacancy is improving, and rental demand is high. Investors with a 5+ year horizon should buy now.

## 2. Market Overview - Median house price: $1,946,269 - Median unit price: $1,223,941 - 1yr price growth: -4.7% (correction from previous highs) - 5yr CAGR: 9.0%/yr (strong long-term trend) - 3yr growth forecast: 13.5% (upside expected) - Days on market: N/A (data not provided) - Market cycle: recovery

The -4.7% 1yr decline signals a buyer's market today. Sellers are adjusting to lower prices after the boom. The 5yr CAGR of 9.0%/yr shows this is a cyclical correction, not a structural decline. The 13.5% 3yr forecast suggests prices will recover and exceed previous peaks. For investors, this is the entry window before the next upswing.

## 3. Rental Market - Median weekly rent: $1,100/wk - Gross rental yield: 2.9% - Vacancy rate: 2.3% (tight market) - Vacancy trend: improving - Rental demand: high - Owner-occupier rate: 79% (low rental supply)

The 2.9% yield is below the 3.5%+ typically required for positive cash flow. However, the 2.3% vacancy rate is well below the 3% equilibrium, meaning tenants are scarce and rents are sticky. The high owner-occupier rate (79%) means limited rental stock, supporting rent growth. Investors should target 3.2%+ yield through value-add or longer holds.

## 4. Short-Term Rental Opportunity - Median nightly rate: $550/night - Occupancy rate: 40% - Estimated annual revenue: $550 x 365 x 40% = $80,300/yr - LTR annual revenue: $1,100/wk x 52 = $57,200/yr

STR generates $23,100 more per year than LTR ($80,300 vs $57,200). However, the 40% occupancy rate is low, indicating seasonal demand. STR requires active management and higher costs (cleaning, utilities, platform fees). For a hands-off investor, LTR is safer. For an active operator, STR offers 40% more revenue. Recommendation: LTR for passive investors; STR for those willing to manage.

## 5. Infrastructure & Growth Drivers - No major projects on file – limited catalyst for near-term price jumps - Transport: Standard suburban transport access (train station, road links) - Employment base: Illawarra region, including Wollongong (unemployment 3.9%, below national average) - Supply pipeline: low – price growth outpacing new supply, limited development pipeline

The low supply pipeline is a positive: limited new stock means existing properties hold value. The 3.9% unemployment rate supports tenant demand. However, no major infrastructure projects mean growth relies on organic demand from Sydney spillover and lifestyle buyers. The suburb's coastal location and train line to Sydney (approx 90 mins) are key demand drivers.

## 6. Bull Case If conditions hold or improve: - 3yr growth forecast of 13.5% would push median house price to ~$2.2M - 5yr CAGR of 9.0%/yr maintained would see $1.946M become ~$3.0M in 5 years - Vacancy rate below 2.0% would push rents to $1,200/wk+, lifting yield to 3.1% - Low supply pipeline means any demand increase flows directly to price appreciation - Recovery cycle suggests the -4.7% 1yr decline is the trough, with upside ahead

The bull case: buy now at $1.946M, hold 5 years, sell at $3.0M – that's $1.05M capital gain plus $286,000 in rent (at $1,100/wk). Total return: $1.336M on $1.946M investment (68.7% return, 11.0% annualised).

## 7. Risks - Distance from CBD: The data flags this as a risk. Thirroul is ~80km from Sydney CBD. This limits capital growth potential compared to inner-ring suburbs. The 5yr CAGR of 9.0% is strong, but Sydney's median 5yr CAGR is ~12%. You're trading growth for lifestyle. - Vacancy risk: 2.3% is low, but if unemployment rises above 5%, vacancy could spike to 4%+, cutting rent by 10-15%. - Single-employer dependency: The Illawarra economy relies on University of Wollongong, health, and manufacturing. A major employer closure would hit demand. - Rate sensitivity: With a $1.946M median, a 1% rate rise adds ~$19,500/yr in interest. Investors need 3.2%+ yield to cover costs at current rates. - Supply pipeline: Low now, but if council approves new developments, supply could increase 10-20% over 3 years, capping price growth.

## 8. The Play - Entry range: $1.8M$2.0M for houses; $1.1M$1.3M for units - Minimum yield to target: 3.2% gross yield (currently 2.9%, so negotiate harder or add value) - Watch signals: - Vacancy rate below 2.0% = buy signal - 3yr forecast of 13.5% = hold for capital growth - Days on market dropping below 30 days = market heating up - Recommended strategy: Buy a house in the $1.8M-$1.9M range, hold for 5+ years. Target 3.2% yield through minor renovations (new kitchen, bathroom). Avoid units – $1.223M median with 2.9% yield is too expensive for the return. Use the STR option if you're active, otherwise LTR for passive income.

Bottom line: Thirroul is a buy for patient investors. The 9.0% 5yr CAGR and 13.5% 3yr forecast justify the entry price. But don't expect quick flips – this is a 5-7 year hold for capital growth, not cash flow.
