Frequently Asked Questions
Should I use gross rent or net rent?
This calculator shows gross rental income (before expenses). For net income, subtract operating expenses, taxes, insurance, and mortgage from the gross figure. Use the cash flow calculator for a complete picture.
How do I handle different rents across units?
Add up all monthly rents and divide by the number of units to get the average rent per unit. Enter that average here, or run separate calculations for each unit type.
What vacancy rate should I use for multi-units?
Multi-unit properties often have slightly higher vacancy (8–12%) than single-family because turnover is more frequent. Check local market data and round up.
