How to analyse a property deal in Australia is a skill that separates investors who build wealth from those who buy on emotion and hope. A proper deal analysis takes a prospective property through four stages: financial modelling (does it make sense on the numbers?), location quality (is the market defensible over a 10-year horizon?), property-specific risk (what problems does this specific property have?), and portfolio fit (does this purchase advance your stated investment goals?).
Stage 1: Financial Modelling — The Numbers First
Run the numbers before you visit the property in person. If the numbers don’t work, the inspection is irrelevant.
Gross Yield: (Annual Rent ÷ Purchase Price) × 100. Example: $28,000 annual rent ÷ $650,000 purchase price × 100 = 4.31% gross yield. This is the starting point, not the end point. Gross yield ignores all costs.
Net Yield: (Annual Rent minus Annual Costs) ÷ Total Investment × 100. Annual costs include: property management (8-10% of rent), council rates ($1,500-$3,500/year), water rates ($800-$1,500), landlord insurance ($1,200-$2,500), maintenance allowance (1% of property value/year), land tax (varies by state), and body corporate levies. Net yield is typically 1.5-2.5% below gross yield.
Deal Analysis — $650K Property at 4.3% Gross Yield
At $164/week net after-tax holding cost, this property requires 5% annual capital growth ($32,500 on $650K) to break even on a total return basis. This is the core trade-off: you are paying $164/week to hold a $650K asset and betting on capital growth to make total return positive. Model this calculation for every property before inspecting.
Stage 2: Location Quality — Is the Market Defensible?
Once the numbers work, assess the location using four filters: employment anchor (is there a stable, recession-resistant employer within 30 minutes — hospital, university, defence, government?), vacancy rate (below 2.0% is landlord-favourable; above 3.5% favours tenants — check SQM Research), population trend (growing populations need more housing, supporting both rental demand and capital growth), and infrastructure investment (hospital expansion, university campus, road or rail — these are forward-looking demand catalysts).
Stage 3: Property-Specific Risk
Assess the specific property: age and condition (pre-1987 may have asbestos; pre-1970 may have original wiring and lead paint); building type (houses generally appreciate better than units in regional markets; strata units carry body corporate levy risk — check sinking fund and meeting minutes); flood, fire, and bushfire risk (check council flood maps and state hazard mapping); and street quality (walk both directions — proximity to noise sources affects tenant quality and achievable rent).
Stage 4: Portfolio Fit
Before making an offer, confirm the property fits your stated investment strategy. If your goal is high yield for cash flow, does this property deliver it? If your goal is capital growth, does this deal fit that strategy? The most common portfolio mistake is buying properties that individually seem reasonable but collectively point in different directions, producing mediocre yield AND mediocre growth instead of a deliberate strategy.
Frequently Asked Questions — Analysing Property Deals
The discipline of running a deal analysis before every property inspection is what separates systematic investors from emotional buyers. Run the financial numbers first and walk away if they don’t work. Of any ten properties you inspect, perhaps two or three will pass all four filters — and those are the ones worth making offers on.
