Summary.
CTA.
Intro: Set the stage. Many beginners look at “Gross Yield” and get excited, but that leads to bankruptcy.
H2 (1): Surface vs. Net.
- Gross (表面): Annual Rent / Property Price. It’s a vanity metric.
- Net (実質): (Annual Rent - Expenses) / (Property Price + Acquisition Costs).
- Key Takeaway: The difference is where the real profit hides. If the gap is huge, the property is a money pit.
H2 (2): Practical Calculation.
- Let’s use numbers. Property: 2,000万円. Annual Rent: 144万円 (12万円/month).
- Gross: 7.2%.
- Expenses: Management (5%), Tax (1%), Repair reserve (5%), Vacancy risk (5%). Total approx 16% of rent? No, let’s use actual yen amounts.
- Expenses: 30万円/year.
- Net: (144 - 30) / 2,000 = 5.7%.
- Insight: The 1.5% difference is your actual cash flow.
H2 (3): Beyond Yield.
- Occupancy rate (稼働率). Even 10% yield is 0 if empty.
- Location (立地). Demographics (population decline in rural areas).
- Repairability (修繕計画). Roof/Waterproofing costs are huge.
H2 (4): The Trap.
- High yield often means high vacancy or high repair needs.
- Example: 15% yield in a shrinking town vs 4% in Tokyo.
- Logic: Cash flow stability > Peak yield.
Refining Tone: Professional, analytical, helpful. Avoid saying “You must do this.” Use “It is recommended to…” or “The logic is…”.
Check Word Count: Ensure depth in each section.
Check SEO: Use “不動産投資”, “利回り”, “計算方法”, “物件選び” naturally.
Check Data Usage: Use specific yen/percentage examples.
Check Style: Vary sentence endings. Ensure “So what?” is answered (e.g., “By calculating Net Yield, you prevent unexpected cash flow shortages”).

Intro: Comparing the dream of passive income vs. the reality of management.
H2 (1): 表面利回りと実質利回りの決定的な違い (Surface vs Net).
H2 (2): 【計算例】実質利回りを算出する3つのステップ (Practical calc).
H2 (3): 利回り以上に重視すべき「物件の生命線」3選 (The 3 lifelines).
H2 (4): 「高利回り物件」の落とし穴を回避する思考法 (Avoiding traps).
Summary: Don’t just look at the surface.
CTA: Simulator.
(Self-Correction during drafting): I need to make sure I explain why the reader should care about the difference between gross and net. It’s about “Cash Flow.” Without cash flow, the investment fails.
