Modelling assumptions
- Country baseline: GB — operating costs 20% of gross rent, income tax 20%, capital appreciation 2.5%/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.
