  • Summary & CTA.

  • Title: Needs to be catchy and SEO-friendly. “Real Estate Investment Yield Calculation Guide | Criteria and Pitfalls.”

  • Intro: Hook the reader. “I bought a property with 10% yield, but I’m losing money every month.” This is a common trap. The goal of this article is to teach how to calculate real profitability.

  • Section 1: Surface vs. Net Yield.

    • Definitions: Surface (Gross) = Rent / Price. Net (Actual) = (Rent - Expenses) / (Price + Costs).
    • The “So what?”: Surface yield is a marketing tool. Net yield is your actual income.
    • Data point: Management fees, taxes, repairs, and vacancy rates can eat up 20-30% of gross rent.

  • Section 2: Simulation Case Study.

    • Scenario A: Surface 10%, Price 20M JPY.
    • Scenario B: Costs (Tax, Management, Repair fund, Vacancy) = 25%.
    • Math:
      • Gross: 2M/year.
      • Net: 2M - (0.5M) = 1.5M.
      • Net Yield = 1.5M / 20M = 7.5%.
    • Lesson: A 10% surface yield might actually be 7.5%. If the bank loan interest is high, the profit vanishes.

  • Section 3: 3 Golden Rules.

    • Rule 1: Location (Demand). High yield in a shrinking town is a trap. Look for population growth/stability.
    • Rule 2: Asset Age/Condition (Depreciation). New builds have low yield; old builds have high maintenance.
    • Rule 3: Occupancy Rate. Even 95% is risky if the market is declining.

  • Section 4: Exit Strategy & Cash Flow.

    • Don’t just look at monthly profit. Look at the total return (IRR).
    • Exit: Can you sell it in 10 years?
    • Cash Flow: The gap between rent and mortgage/expenses. If CF is zero or negative, you’re just a “manager of a debt.”

  • Summary: Reiterate the importance of Net Yield and Exit Strategy.

  • CTA: “Calculate your potential returns with the OpenClaw Simulator.”

  • Check Tone: Is it too salesy? No, it’s educational. Is it repetitive? Use varying sentence endings (～でしょう, ～といえます, ～が重要です, ～に注意しましょう).

  • Word Count Check: Ensure depth in each section.

  • SEO keywords: 不動産投資 (Real estate investment), 利回り (Yield), 計算方法 (Calculation method), 物件選び (Property selection), 表面利回り (Gross yield), 実質利回り (Net yield).

  • Self-Correction during drafting: I initially thought about just listing formulas, but the prompt asks “So what?”. I need to emphasize that “high yield often hides high risk.”

  • 2-4 paragraphs per section? Yes.

  • Numbers/Data? Yes (20-30% expense ratio, specific simulation).
