🏘️ Rental Property Calculator

What is the Rental Property Calculator?

This is a comprehensive financial tool designed for real estate investors to quickly and accurately model the **profitability and financial performance** of a potential rental property purchase. It goes beyond simple rent vs. mortgage comparisons by calculating the actual returns on investment.

Why You Need This Tool and Its Purpose

Real estate investing is complex, requiring you to analyze multiple variables (financing, operating expenses, and income). The primary purpose of this calculator is to answer three critical investor questions:

1. **What is my Cash Flow?** Determine the exact dollar amount remaining in your pocket each month after all expenses and debt payments are covered. Positive cash flow is essential.
2. **What is the Cap Rate?** This metric ($ \text{NOI} / \text{Price} $) helps you compare the profitability of one investment property to others in the market *before* considering financing.
3. **What is the Cash-on-Cash (CoC) Return?** This is the most crucial metric for leveraged investors ($ \text{Annual Cash Flow} / \text{Total Cash Invested} $), showing the annual return percentage on the money you actually put down.

How This Calculator Works

The calculation follows a standard investor pro-forma model:

1. **Gross Income:** $\text{Monthly Rent} \times 12$.
2. **Net Operating Income (NOI):** Gross Income minus all annual operating expenses (Taxes, Insurance, Vacancy, Maintenance, Management Fees).
3. **Monthly Cash Flow:** $(\text{NOI} / 12) - \text{Monthly Debt Service (P\&I)}$.
4. **Cap Rate:** $(\text{NOI} / \text{Purchase Price}) \times 100$.
5. **Cash-on-Cash Return:** $(\text{Monthly Cash Flow} \times 12) / \text{Total Cash Invested} \times 100$. (Total Cash Invested includes Down Payment, Closing Costs, and Renovation Costs).
