What's the difference between Cap Rate and Cash-on-Cash Return?

Cap Rate measures return based on the property's total value, independent of financing (NOI / Property Value). Cash-on-Cash Return measures return based on your actual cash invested (Annual Cash Flow / Cash Invested). Cap Rate is useful for comparing properties, while Cash-on-Cash shows your actual return on invested money.

What expenses should I include when calculating NOI?

Include all operating expenses: property taxes, insurance, property management (8-12% of rent), maintenance and repairs, utilities (if paid by owner), vacancies (5-10% of rent), and capital expenditures reserves (5-10% of rent). Don't include mortgage payments in NOI—that's factored into Cash-on-Cash calculations.

What's a good Cap Rate for a rental property?

Good Cap Rates vary by market. In expensive coastal markets, 4-6% is common. In more affordable areas, 7-10% is typical. The calculator helps you determine if the property's Cap Rate is competitive for its market. Generally, higher Cap Rates indicate better cash flow but may come with higher risk or lower appreciation potential.

What's a good Cash-on-Cash return for a rental property?

A good Cash-on-Cash return is typically 8-12%. This means you're earning 8-12% annually on your invested cash (down payment and closing costs). The calculator shows your Cash-on-Cash return and helps you compare it to other investment options. Returns above 15% are excellent but often come with higher risk.

How do I calculate the mortgage payment for a rental property?

The calculator uses the standard mortgage payment formula: P = L × [r(1+r)^n] / [(1+r)^n - 1], where P is the monthly payment, L is the loan amount, r is the monthly interest rate, and n is the number of months. You input the loan amount, interest rate, and term (typically 30 years), and the calculator determines the payment.

What's the difference between appreciation and cash flow in rental property ROI?

Cash flow is the monthly income you receive after expenses (rent minus all costs). Appreciation is the increase in the property's value over time. Both contribute to your total ROI. The calculator shows both separately and combined, helping you understand the total return. Some investors prioritize cash flow, others appreciation.

How should I account for vacancies in my rental property analysis?

The calculator includes a vacancy rate (typically 5-10%) to account for periods when the property isn't rented. This reduces your effective rental income and ROI. More conservative investors use 10% to account for turnover costs (cleaning, advertising, minor repairs between tenants).

What is the 1% rule and does this calculator use it?

The 1% rule says that monthly rent should be at least 1% of the purchase price (e.g., $2,000 rent on a $200,000 property). The calculator shows if the property meets this rule but doesn't rely on it exclusively. The 1% rule is a quick screening tool—the calculator provides a more thorough analysis.

What's the difference between positive and negative cash flow?

Positive cash flow means your rental income exceeds all expenses (including mortgage), generating monthly profit. Negative cash flow means you're losing money each month, hoping for appreciation to compensate. The calculator clearly shows your monthly cash flow, helping you decide if the investment is sustainable.

How do I account for property management if I manage the property myself?

Even if you self-manage, the calculator includes a property management fee (typically 8-12% of rent) to account for the value of your time. This provides a more realistic ROI comparison to professionally managed properties. If you want to see the impact of self-management, you can adjust this percentage down or to zero.
