The Problem with Cap Rate
Every real estate investor has heard: "What's the cap rate?" But here's the truth: true cap rate requires property-specific expenses, which we don't have at the area level.
Instead, we calculate gross rental yield — a more conservative, transparent metric that doesn't hide assumptions about expenses.
Cap Rate (What We Don't Use)
Why we don't use it for area-level analysis:
- NOI requires property-specific expenses — maintenance, management, insurance, strata or body corporate fees, etc.
- Expenses vary wildly — A coastal property (higher insurance) has very different costs to an equivalent inland property, regardless of country
- Hidden assumptions — Most "cap rate calculators" use generic %s (e.g., 1% maintenance) that don't match reality
- Not comparable across markets — A 6% cap rate in a high-tax region is not the same as 6% in a low-tax region, even within the same country
Gross Rental Yield (What We Use)
Why we use it:
- Transparent — No hidden expense assumptions
- Comparable — Same calculation for all markets
- Conservative — Investors can subtract their own expected expenses
- Data-driven — Based on actual market rent and prices, not estimates
Example Calculation
Illustrative example — a mid-sized regional market:
- Median 2-bed house price: 285,000
- Median 2-bed house rent: 1,850/month
- Annual rent: 1,850 × 12 = 22,200
- Gross Yield: 22,200 / 285,000 = 7.79%
From Gross Yield to Net Yield
To estimate net yield (closer to cap rate), subtract typical expenses:
| Expense | % of Rent | Annual (illustrative) |
|---|---|---|
| Gross Rent | — | 22,200 |
| Property Tax / Rates (1.8%) | 23% | -5,130 |
| Insurance | 5% | -1,200 |
| Maintenance (0.6%) | 8% | -1,710 |
| Management (10%) | 10% | -2,220 |
| Vacancy (5%) | 5% | -1,110 |
| Net Operating Income | 49% | 10,830 |
| Net Yield (Cap Rate) | 3.80% | |
Key insight: Gross yield of 7.79% becomes net yield of 3.80% after expenses. This is normal.
Why Gross Yield > Cap Rate for Comparison
1. Expenses Are Local
A coastal property can have significantly higher insurance than an equivalent inland property. Using gross yield lets investors apply their own local expense assumptions.
2. Management Varies
Self-managing? 0% management fee. Using a property manager? 8-12%. Gross yield doesn't assume one or the other.
3. Maintenance Depends on Age
A 2020 build has 0.4% maintenance. A 1950 build has 1.2%. Gross yield doesn't pick a number for you.
4. Vacancy Is Strategy-Dependent
Aggressive pricing? 2% vacancy. Cautious pricing? 8% vacancy. Gross yield lets you decide.
When to Use Each Metric
Use Gross Yield When:
- Comparing markets across multiple regions or countries
- Screening for high-return opportunities
- You don't have property-specific expense data
- You want a conservative, transparent metric
Use Cap Rate (Net Yield) When:
- Analysing a specific property
- You have actual expense quotes (insurance, strata or body corporate fees, etc.)
- Comparing similar properties in the same market
- Making a final buy/no-buy decision
Our Dashboard Provides Both
When you use our interactive dashboard, you get:
- Gross Yield: Market-level comparison (transparent, no assumptions)
- Net Cash Flow: Property-level projection (with your specific financing, expenses, and assumptions)
This gives you both the big picture (which markets are promising) and the details (what returns you can expect with your strategy).
Common Misconceptions
"Gross yield is misleading because it ignores expenses"
False. Gross yield is transparent because it doesn't hide generic expense assumptions. Investors know they need to subtract expenses — gross yield gives them a clean starting point.
"Cap rate is more accurate"
Only if you have property-specific expenses. A "cap rate" calculated with generic percentages (1% maintenance, 10% management) is less accurate than gross yield because it pretends to know expenses it doesn't.
"I should target 8%+ cap rate"
Depends on the market. A 6% cap rate in a low-tax, low-risk market may be better than an 8% cap rate in a high-tax, high-risk market. Always compare net yield after all local costs.
Real-World Rule of Thumb
For long-term rentals with typical management:
(Expenses typically eat 50% of gross rent)
For short-term rentals with typical management:
(Higher expenses: 15% management, cleaning, furnishing)
Use these as quick screening filters, then calculate exact expenses for properties you're serious about.
