Modelling assumptions
  • Country baseline: FR — operating costs 22% of gross rent, income tax 25%, capital appreciation 2.0%/yr.
  • Projections assume rent grows at the country appreciation rate. Real-world rent growth will diverge.
  • Mortgage figures use a constant interest rate for the full term. Re-mortgage events are not modelled.
  • Excludes capital-gains tax on exit, currency hedging costs and any local property tax over and above the operating buffer.
