What is a rental property calculator?

A rental property calculator is a tool that helps real estate investors analyze potential rental properties by calculating key metrics like cash flow, cap rate, cash-on-cash return, and ROI. It allows you to quickly determine if a property will generate positive cash flow and meet your investment goals.

What is a good cap rate for rental property?

A good cap rate typically ranges from 4% to 10%, depending on the market. Lower cap rates (4-6%) are common in stable, high-demand markets with strong appreciation potential. Moderate cap rates (6-8%) indicate stable markets with good rental demand. Higher cap rates (8-10%) suggest emerging markets with higher returns but also higher risk.

What is cash-on-cash return?

Cash-on-cash return measures the annual return on the actual cash invested in a property. It's calculated as (Annual Cash Flow / Total Cash Invested) × 100. This metric is especially useful for financed purchases as it shows the return on your down payment and closing costs, not the full purchase price.

How do you calculate monthly cash flow?

Monthly cash flow = Monthly Rent - (Monthly Mortgage + Property Tax + Insurance + Maintenance + Vacancy Reserve + Property Management). Positive cash flow means the property generates income each month after all expenses.

What expenses should I include in my rental property analysis?

Include all operating expenses: property taxes, insurance, maintenance (typically 1% of property value annually), vacancy rate (5-10% is typical), property management fees (8-12% if using a PM company), and closing costs (2-5% of purchase price). Don't forget to account for capital expenditures for major repairs.

Cash vs. financing - which is better for rental properties?

Cash purchases eliminate mortgage risk and maximize cash flow, but tie up more capital. Financing allows leverage to buy multiple properties and can increase ROI through cash-on-cash returns. Use this calculator to compare both scenarios and determine which strategy works best for your goals.

What is NOI (Net Operating Income)?

NOI is the annual income from a property after all operating expenses but before financing costs. It's calculated as Annual Rent - Annual Operating Expenses. NOI is used to calculate cap rate and is a key metric lenders use to evaluate investment properties.
