    • Explain that the old “any new house” rule is gone.
    • Classify: ZEH, Energy-saving, etc.

  • SEO Keywords: 住宅ローン減税, 最新ルール, 省エネ基準, 控除額, 繰り上げ返済.

  • Initial thought: Should I talk about all types of houses?

  • Correction: Focus on the impact of the energy-saving classification, as that’s the biggest recent change.

  • Refinement on numbers: Use specific loan limits from the 2024 tax reforms (e.g., ZEH vs. non-energy saving). Note: For 2024, non-energy saving houses might not even qualify for certain deductions depending on the year of construction/rules. Actually, for new builds in 2024, they must meet minimum energy standards to qualify for the deduction at all. This is a crucial point for “So what?”.
