The Five-Step Framework Every Investor Should Know
You find a property listing. The numbers look decent on the surface. But how do you actually know if it's a good investment? Most new investors either jump to one number or get paralyzed by complexity. The truth: analyzing a rental property is straightforward with the right framework.
Step 1: Calculate Your Total Cash Investment
Total Cash Invested = Down Payment + Closing Costs + Initial Repairs
- Purchase price: $200,000
- Down payment (20%): $40,000
- Closing costs (2–3%): $4,000
- Initial repairs: $3,000
- Total cash invested: $48,500
Step 2: Estimate Your Annual Income (Be Conservative)
Check comparable rents on Zillow, Apartments.com, and local listings. Build in a 5–10% vacancy buffer.
- Market rent: $1,300/month
- Annual rental income: $15,600
- Vacancy loss (5%): -$780
- Effective gross income: $14,820
Step 3: Subtract Operating Expenses
This is where most novice investors go wrong. Owning rental property costs money beyond the mortgage.
- Property taxes (0.8%): -$1,600
- Insurance: -$900
- Maintenance (1% of value): -$2,000
- Net Operating Income (NOI): $10,320
Step 4: Calculate Your Key Investment Metrics
Cap Rate: $10,320 ÷ $200,000 = 5.16%
Cash-on-Cash Return: With financing at 6.5% over 30 years, annual mortgage is $9,936. Cash flow = $384/year. Cash-on-cash = $384 ÷ $48,500 = 0.79%. This property barely cash flows.
DSCR: $10,320 ÷ $9,936 = 1.04. Lenders want 1.2+. This is a red flag.

Step 5: Assess Risk and Make Your Decision
Ask three risk questions: Is the neighborhood strong? Is there upside potential? What's your exit strategy?
In this example, the property barely cash flows (0.79% return) and the DSCR is tight (1.04). Unless there's strong appreciation expected, you should probably pass.
Quick Reference: Target Metrics
- Cap rate: 5–8%
- Cash-on-cash return: 5–12%
- DSCR: 1.2 or higher
- Vacancy buffer: 5–10%
