5 Things to Look For When Evaluating Australian Investment Properties

Gross yield (annual rent ÷ purchase price × 100) is the starting point, not the endpoint. A property yielding 6% gross sounds attractive — but once you subtract property management fees (8–10%), vacancy periods, maintenance, rates, water, insurance, and strata levies, the net yield might be 3.5%. That changes the investment case significantly.

What to look for: Gross yield of 5%+ in a target suburb, with a net yield calculation that still produces positive or near-neutral cash flow after all costs. Never evaluate yield without building a full 12-month cash flow model — even a rough one changes what properties you'll actually consider.

The benchmark trap: Comparing yield across different cities is misleading. A 4% yield in inner-city Sydney might outperform a 6.5% yield in a regional mining town once capital growth, vacancy risk, and holding cost differences are factored in. Always compare within comparable market segments.

You can buy an excellent property in a suburb with poor fundamentals and underperform the market for a decade. Suburb selection is arguably more important than the individual property. The fundamentals I evaluate:

• Population growth trends: Is this suburb attracting new residents? ABS data and council forecasts give you the 5–10 year trajectory. Growing population = growing demand.
• Infrastructure investment: Announced or underway rail extensions, motorway upgrades, shopping centre developments, university campuses, or hospital expansions are powerful long-term price catalysts. The time to buy is before the ribbon-cutting.
• Employment diversity: A suburb driven by a single major employer (a mine, a military base, a single large factory) carries concentrated risk. Diverse local employment sources create resilient rental demand.
• Supply pipeline: How many new dwellings are approved or under construction in the area? High supply growth in a suburb with flat demand suppresses both rents and capital values.
• Days on market trend: If average days on market are falling and stock levels are low, demand is outpacing supply. A vanity metric on its own, but useful as part of a larger picture.

Most investors evaluate a property at purchase. The ones who consistently outperform evaluate it at year 3 and year 10 as well. A modestly negative cash flow property at purchase that becomes positively geared within 3 years (via rent increases) is a fundamentally different investment from one that stays negative for a decade.

Build three scenarios for every property you're seriously considering:

• Base case: CPI-level rent increases (2–3% per annum), standard vacancy rate (4%), mortgage rate at your current approved rate.
• Stress case: Vacancy of 8%, no rent increase for 2 years, 1% rate rise. Can you service this without needing to sell at a loss?
• Growth case: Strong rent growth (5–6% per annum), sub-3% vacancy, rates flat or falling. What does your return look like?

If your stress case breaks the investment thesis entirely, the property doesn't have adequate margin of safety. Move on.

Historical capital growth numbers are seductive and frequently misleading. A suburb that doubled in value over the past 10 years may be at peak, overpriced relative to fundamentals, and due for a decade of sideways movement. What matters more are the forward-looking capital growth drivers.

Structural drivers worth identifying:

• Land scarcity — is this an area where you simply can't build more of what you're buying?
• Gentrification trajectory — is the suburb moving upmarket? Track café density, independent retail, renovation activity.
• Proximity to high-income employment hubs — proximity to CBDs, tech precincts, medical corridors.
• School catchment zone changes — in family-dominated suburbs, school zone boundary shifts can materially move prices.
• Zoning changes — potential rezoning to higher density increases land value independent of the existing structure.

A high-quality investment property with a poor property manager will underperform a mediocre property with an exceptional one. I've seen this play out repeatedly. Your property manager is your eyes, ears, and hands on the ground — especially if you're investing interstate or internationally.

What to look for when selecting a property manager:

• Local portfolio size: between 100–300 properties per office (large enough to have systems, small enough to care)
• Average days to fill vacancy — benchmark is under 14 days for a well-priced property
• Tenant vetting process — ask specifically what checks they run and what their criteria are
• Maintenance response standards — how quickly are maintenance requests actioned? What's their preferred trades network?
• Communication cadence — monthly statement is table stakes; proactive communication about market conditions is the differentiator
• Their approach to rent reviews — are they proactive about annual reviews, or do they let rents stagnate?

Interview at least three property managers before committing. Ask for references from current landlord clients. The 8–10% management fee difference between a good and mediocre agency is trivial compared to the impact of a poorly managed vacancy or neglected maintenance issue.
