✅ Premium location - chiado is a stable, high-demand area with strong long-term appreciation potential
⚠️ NEGATIVE CASH FLOW - This property will cost you money each month with current financing
Consider: higher down payment (lower mortgage), negotiate purchase price, or increase rental income
✅ Move-in ready property in prime location - ideal for immediate rental or personal use
ℹ️ Tourist area - Consider Alojamento Local (short-term rental) for higher yields, but note strict licensing requirements and regulatory changes

KEY METRICS
Understanding investment metrics
Gross Rental Yield
Annual rent as a percentage of property purchase price (before expenses)
(Annual Rent ÷ Property Price) × 100
Tip: This is your starting point. Premium Lisbon areas (Chiado, Príncipe Real) typically yield 3.5-4% due to high prices. Emerging areas (Marvila) can reach 5-5.5%.
Lisbon Market: The calculator uses your entered rent (or sample property rent). Occupancy rate (default 95%) affects effective rent. Prime areas yield less but appreciate faster (3-7% annually).
Net Rental Yield
Annual profit after all operating expenses, as a percentage of property price
((Annual Rent - Total Annual Expenses) ÷ Property Price) × 100
Tip: This shows your real income return. Includes IMI tax, maintenance, management, vacancy, condominium fees, mortgage payments, and amortized one-time costs (IMT, legal fees).
Lisbon Market: Default expenses: IMI 0.3%, maintenance 1%, management 8%, vacancy 5%, condominium €80/month. One-time costs (IMT 6%, legal 1.5%, notary €600) are spread over 10 years.
ROI (Cash-on-Cash Return)
Annual return on your actual cash investment (down payment + acquisition costs)
((Annual Rent - Total Expenses) ÷ Cash Invested) × 100
Tip: This is your most important metric if using a mortgage. Cash invested = down payment + IMT + legal fees + notary + registration. Shows how efficiently your capital works.
Lisbon Market: With 80% mortgage (20% down), achieving 6-8% ROI is realistic in good Lisbon neighborhoods. Cash purchases typically show lower ROI percentages but higher absolute returns.
Payback Period
Years to recover your cash investment through net rental income alone (ignores appreciation)
Cash Invested ÷ Net Annual Income
Tip: Shorter is better, but premium areas with longer payback (25-30 years) can still outperform due to strong appreciation (3-7% annually). If negative cash flow, payback is infinite.
Lisbon Market: Premium areas: 25-30 years typical, but strong appreciation compensates. Emerging areas: 18-22 years. Under 18 years is excellent. The calculator shows "Never" if monthly net income is negative.
