Quick Answer
Calculate rental property ROI using cash-on-cash return: Annual Cash Flow ÷ Total Cash Invested × 100. For a $300,000 property with $60,000 down, $2,200/month rent, and $1,700/month expenses (mortgage, taxes, insurance, maintenance), your annual cash flow is $6,000, giving a 10% cash-on-cash return. Total return including appreciation and equity buildup is typically 15–25%.
Key Takeaways
- Cash-on-cash return measures annual cash flow relative to your down payment — target 8–12%.
- Cap rate = Net Operating Income ÷ Property Value — useful for comparing properties.
- Total return includes cash flow + appreciation + mortgage paydown + tax benefits.
- A $300K rental with $60K down generating $500/month cash flow = 10% cash-on-cash return.

Real estate ROI is more complex than stock returns because leverage, taxes, and multiple return streams are involved. A rental property generates returns in four ways simultaneously: monthly cash flow, property appreciation, mortgage principal paydown, and tax benefits.
Method 1: Cash-on-Cash Return
The most practical measure for rental investors:
- Formula: Annual Pre-Tax Cash Flow ÷ Total Cash Invested × 100
- Cash invested includes: Down payment + closing costs + renovation costs
- Cash flow = Annual rent − mortgage − taxes − insurance − maintenance − vacancy allowance − property management
- Good target: 8–12% cash-on-cash return
- Example: $6,000 annual cash flow ÷ $65,000 cash invested = 9.2% CoC return
Method 2: Cap Rate
Cap rate removes financing from the equation to compare properties objectively:
- Formula: Net Operating Income (NOI) ÷ Property Value × 100
- NOI = Annual rent − operating expenses (excludes mortgage payments)
- Average cap rates (2026): 4–6% in major metros, 6–10% in smaller markets
- Use case: Comparing properties regardless of financing terms
Total Return: The Full Picture
Cash flow is just one component. A realistic total return calculation:
- Cash flow: $6,000/year (9.2% on cash invested)
- Appreciation: 3% on $300K = $9,000/year
- Mortgage paydown: ~$3,600/year in principal reduction (year 1)
- Tax benefits: Depreciation ($10,900/year on a $300K property) offsets taxable income
- Total first-year return: $18,600+ on $65,000 invested = ~28.6% total ROI
Realistic Expense Estimates for 2026
New investors underestimate expenses. Budget for these:
- Vacancy: 5–8% of gross rent (even good properties have turnover)
- Maintenance: 8–12% of gross rent or 1% of property value/year
- Property management: 8–10% of gross rent if hiring a manager
- Capital expenditures (CapEx): 5–10% of rent set aside for roof, HVAC, appliances
- Insurance: $1,200–$3,000/year depending on location and coverage

Frequently Asked Questions
What is a good ROI for rental property?
Target 8–12% cash-on-cash return for a cash-flowing rental. Total return (including appreciation and equity) of 15–25% is realistic for well-chosen properties. Below 6% cash-on-cash, you may be better off in index funds with less hassle. Above 15% cash-on-cash usually means higher risk or a value-add opportunity.
Is the 1% rule still valid in 2026?
The 1% rule (monthly rent should be at least 1% of purchase price) is increasingly difficult to meet in major markets. In 2026, many profitable rentals achieve 0.6–0.8%. The rule remains useful as a quick screening filter but should not be the sole criterion. Focus on actual cash flow analysis instead.
How does leverage affect rental ROI?
Leverage (using a mortgage) amplifies returns both up and down. Buying a $300K property with $60K down means 5x leverage. If the property appreciates 5% ($15K), that is a 25% return on your $60K. But if it drops 5%, you lose 25% of your investment. Leverage also increases monthly expenses (mortgage payment), reducing cash flow.
