Calculator Tips & Best Practices
💡 Using This Calculator Effectively
- • Be Conservative: Use higher expense estimates and lower rent to build in safety margin
- • Include All Costs: Don't forget utilities, landscaping, pest control, etc.
- • Factor Vacancies: Even with great tenants, plan for turnover periods
- • Compare Multiple Scenarios: Test different down payments and loan terms
- • Check Market Rents: Verify your rent estimates on Zillow, Rentometer, or with local property managers
- • Update Regularly: Rates and property values change - recalculate often
⚠️ Common Calculation Mistakes
- • Underestimating Maintenance: Budget 10-15% of rent minimum for multi-family
- • Forgetting Capex: Roof, HVAC, water heater replacements add up
- • Ignoring Property Management: Even self-managed properties have opportunity cost
- • Overoptimistic Rent: Using "ideal" vs. actual market rents
- • No Vacancy Buffer: 100% occupancy is unrealistic
- • Missing HOA Fees: Can be $200-400/month for condos
