Understanding Rental Property Investment Analysis

Rental property investing involves purchasing real estate to generate ongoing rental income while building equity through property appreciation. Success requires careful analysis of cash flow, return metrics, and market conditions to ensure the investment meets your financial goals and risk tolerance.

This calculator provides comprehensive analysis of key rental property metrics including cap rate, cash-on-cash return, IRR, and adherence to common real estate investment rules like the 1% and 50% rules that help investors quickly evaluate opportunities.

Key Rental Property Metrics

Cap Rate (Capitalization Rate)

Cap Rate = Net Operating Income ÷ Purchase Price

Measures property's income-generating potential independent of financing

Cash-on-Cash Return

Cash-on-Cash = Annual Cash Flow ÷ Total Cash Invested

Shows return on actual cash invested including down payment and closing costs

Internal Rate of Return (IRR)

Discount rate that makes NPV of all cash flows equal zero

Accounts for time value of money and varying cash flows over holding period

Real Estate Investment Rules

1% Rule: Monthly rent should equal at least 1% of purchase price ($300K property = $3K+ rent)
2% Rule: More aggressive target of 2% monthly rent (harder to achieve but excellent cash flow)
50% Rule: Operating expenses typically consume about 50% of gross rental income
70% Rule (Flipping): Pay no more than 70% of after-repair value minus repair costs
