Property breakdown
Analyze the deal in layers
A useful rental analysis separates property operations from financing. Effective income is rent and other income after vacancy. Operating expenses are deducted to produce net operating income (NOI). Mortgage payments are then deducted from NOI to estimate cash flow.
Cap rate measures unlevered property performance, while cash-on-cash return measures annual cash flow relative to the cash you invested. DSCR compares NOI with debt service. The 1% rule is shown only as a quick rent-to-price screen.
Frequently asked questions
What expenses should I include?
Include recurring property taxes, insurance, HOA, maintenance, management, CapEx reserves, utilities you pay and other operating expenses.
What is NOI?
NOI is effective property income minus recurring operating expenses before mortgage payments and income taxes.
What is DSCR?
Debt-service coverage ratio compares NOI with debt service. A value above 1 means NOI exceeds the modeled mortgage payment.
Is appreciation included?
No. This page focuses on current operating performance and cash flow; use the rental property ROI calculator for a multi-year appreciation scenario.
