What is the difference between cap rate and ROI?

Cap rate measures net operating income divided by property value ($16,000 / $300,000 = 5.3% after expenses, or 8.0% on gross rent), independent of financing. ROI measures your actual return on the cash you invested ($16,000 / $60,000 = 26.7%), so leverage amplifies ROI above the cap rate when you use a mortgage.

How does vacancy rate impact rental property ROI?

A 5-8% national average vacancy rate reduces $24,000 annual rent by $1,200-$1,920 per year, directly lowering cash-on-cash returns by 2-3 percentage points. Budget for at least one month of vacancy annually and factor turnover costs like cleaning and advertising into your ongoing expense projections.

How does leverage affect rental property returns?

With a $60,000 down payment on a $300,000 property, a 5% annual appreciation adds $15,000 in equity while you only invested $60,000 — a 25% return on equity from appreciation alone. Combined with rental income, leveraged returns can reach 30-40% annually, though mortgage interest and maintenance costs reduce net gains.

Rental Property ROI Calculator

Calculate the ROI on a rental property investment including purchase price, rental income, and operating expenses. Compare against alternative investments.

Rental property investors typically put down 20-25% of the purchase price as their initial investment. For a $300,000 property with a $60,000 down payment, rental income of $2,000/month, and annual operating expenses around $8,000 (property taxes, insurance, maintenance, and management fees), the cash-on-cash ROI calculation reveals whether the property generates adequate returns relative to the capital deployed and the hands-on effort required.

Key Considerations

With a $60,000 down payment, $24,000 annual rent, and $8,000 in operating costs, your first-year cash-on-cash ROI is approximately 23.5% before mortgage payments — strong compared to most passive investments.
At 3% annual rent growth, your $24,000/year rental income rises to $27,812 by year 5 — adding $3,812 in annual revenue without any additional investment, which significantly improves cumulative ROI.
Budget 1% of property value annually for maintenance and repairs ($3,000 on a $300,000 property). Underfunding maintenance reduces long-term ROI through deferred costs and lower resale value.
Vacancy rates average 5-8% nationally. On $24,000 annual rent, expect to lose $1,200-$1,920 per year to vacancy. Factor this into your ongoing costs for a realistic ROI projection.
Depreciation deductions (approximately $10,900/year on a $300,000 residential property) reduce taxable income without reducing cash flow, boosting after-tax ROI by 15-25% for investors in the 22-32% tax bracket.

Annual rental income	$24,000 ($2,000/month)
Cap rate	8.0% ($24,000 / $300,000)
Cash-on-cash return	23.5% before mortgage payments

Net operating income	$16,000/year after expenses

How This Compares

Rental property cash-on-cash returns of 20-25% typically exceed the S&P 500's 10.3% historical average, but require active management, illiquid capital, and tolerance for vacancy risk. Stock market investing offers instant liquidity and zero maintenance, while rental properties provide leverage, tax advantages through depreciation, and inflation hedging through rising rents.
