What is Buy-to-Let?
Buy-to-Let (BTL) is a property investment strategy where you purchase a property specifically to rent it out to tenants. The goal is to generate passive rental income while the property appreciates in value over time.
Key BTL Metrics Explained:
- Gross Yield: Annual rental income ÷ property price × 100. Shows total return before expenses.
- Net Yield: Annual profit after all costs ÷ property price × 100. Your actual return.
- Cash-on-Cash Return: Annual profit ÷ deposit × 100. Shows return on your actual investment.
- Monthly Cash Flow: Rental income minus all monthly costs. Positive = profit, negative = loss.
