Loan styles, buyer support and calculator limits

Floating-rate mortgages are common, alongside fixed-period and full-term fixed products. Land and building values are distinguished, and condominium management and repair-reserve fees sit outside the mortgage.

Common loan styles

  • Floating-rate bank mortgage
  • Fixed-period mortgage that resets after the selected term
  • Flat 35 long-term fixed mortgage offered through lenders with the Japan Housing Finance Agency

Government or structured support

  • Flat 35 S and related programs may reduce rates for qualifying energy-efficient, durable or family-oriented homes
  • Home-loan tax deductions depend on occupancy, income, building and tax-year rules
  • Local relocation, vacant-home and family support programs vary and are not national entitlements

What to verify locally

  • Separate land/building and condo fees when data is available
  • Fixed-period and full-term fixed are different products
  • Government-linked rate reductions require property certification
