  • Intro: Hook the reader. “Buying a condo isn’t just about the purchase price. The recurring costs can be a silent killer.”

  • Section 1 (Data):

    • Use estimated figures (based on general market knowledge/MLIT reports).
    • Management fees (Kanri-hi): ~¥15,000-25,000.
    • Repair reserves (Shuzen-tsumitate-kin): ~¥10,000-20,000.
    • Note the difference between urban (Tokyo/Osaka) and rural/suburban.
    • Note that older buildings tend to have higher repair reserves.

  • Section 2 (The Trap):

    • “Why is it so cheap?”
    • Indicator 1: Service level (cleaning, security).
    • Indicator 2: Management company’s quality.
    • Indicator 3: Deferred maintenance (the “hidden debt”).
    • So what? Low costs now = huge spikes later.

  • Section 3 (Repair Reserve Risks):

    • The “Repair Fund Shortage” problem.
    • Consequences: Sudden massive hikes (e.g., ¥5,000 -> ¥30,000), difficulty in selling (lower liquidity), physical deterioration.
    • Mention “Long-term Repair Plan” (Choki Shuzen Keikaku).

  • Section 4 (How to choose):

    • Don’t just look at the monthly total.
    • Look at the trend (is it increasing gradually or has it been flat for 10 years?).
    • Look at the reserve amount per square meter.
    • Look at the “Current Balance” vs. “Future Planned Costs.”

  • Summary: Wrap up key points.

  • Avoid “desu/masu” repetition. Use “～だろう”"～といえます""～が重要です" variety.

  • Ensure the tone is “Research Center” (objective/analytical).

  • Intro: Emphasize that these are “lifestyle costs” that last 30-50 years.

  • Section 1: Refine data points. Management fee (average 20k), Repair fund (average 15k). Explain that Tokyo is higher due to services (concierge).

  • Section 2: Explain the “low fee” trap. If the fee is too low, the “Long-term Repair Plan” is likely ignored.

  • Section 3: Focus on “Liquidity.” A condo with a broken fund is hard to sell. This hits the reader’s pocket.

  • Section 4: Provide a checklist. (1. Plan existence, 2. Increasing trend, 3. Fund balance).

  • 1500-2000 words? (I need to expand on details to ensure depth).

  • H2 structure? Yes.

  • Data used? Yes.

  • “So what?” included? Yes.

  • No salesy tone? Yes.
