Understanding Your Results
  • Cash-on-Cash ROI: Your annual return as a percentage of cash invested (deposit + costs)
  • Net Yield: Annual rental income minus costs, as % of property value
  • Good ROI: Target 8-12% cash-on-cash for strong BTL performance
  • Tax Considerations: This excludes income tax on rental profits (20-45% depending on band)
  • Void Periods: Allow 1-2 months annual void in your budget planning
  • Capital Growth: ROI calculation excludes property appreciation potential
