Quick Answer

Real estate investment analysis includes: Cap Rate = NOI / Property Value, Cash-on-Cash = Annual Cash Flow / Cash Invested, ROI = Total Return / Total Investment. Our calculator provides comprehensive property analysis.

Key Facts

  • Cap rate = Net Operating Income / Property Value
  • Cash-on-cash return = Cash Flow / Cash Invested
  • Good cap rate varies by market (4-10%)
  • Include all expenses in NOI calculation
  • Leverage amplifies returns and risks
  • Consider appreciation and tax benefits

Frequently Asked Questions

Cap rate (capitalization rate) measures a property's potential return based on NOI (Net Operating Income) divided by purchase price. A 6% cap rate means the property generates 6% of its value annually before mortgage. Higher cap rates indicate higher potential returns but often higher risk.

NOI ÷ Purchase Price. Measures return before mortgage. Higher = more return (and risk).

Cash-on-cash return measures annual cash flow divided by total cash invested (down payment + closing costs). It shows the actual return on your invested capital. A 10% cash-on-cash return means you earn $10,000 annually on a $100,000 investment.

Annual Cash Flow ÷ Cash Invested. Measures return on your actual investment.

The 1% rule is a quick screening tool: monthly rent should be at least 1% of purchase price. A $200,000 property should rent for $2,000+/month. Properties meeting this rule often cash flow well, but it's just a starting point for analysis.

Monthly rent ≥ 1% of purchase price. Quick screening tool for cash flow potential.

DSCR measures ability to cover mortgage payments with NOI. DSCR = NOI ÷ Annual Mortgage Payment. Lenders typically require 1.2-1.25 minimum. A 1.25 DSCR means NOI is 25% higher than mortgage payments, providing a safety cushion.

NOI ÷ Mortgage. Minimum 1.2-1.25 for lenders. Higher = safer investment.

Key expenses: Property taxes (varies by location), insurance (0.5-1% of value), maintenance/repairs (1-2% of value for reserves), property management (8-10% of rent if hired), vacancy (5-10% of rent), utilities (if included), and HOA fees if applicable.

Taxes, insurance, maintenance (1-2%), management (8-10%), vacancy (5-10%), utilities, HOA.
