Getting Started

Enter the expected monthly rent, vacancy rate, property taxes, insurance, HOA fees, and maintenance costs. Be conservative with your estimates for accurate results.

4. Analyze Results

Click "Run Analysis" to see your ROI, Cap Rate, Cash Flow, and detailed projections. Save properties to compare multiple deals.

Key Metrics Explained

Cap Rate

Capitalization Rate measures the property's return without financing.

Cap Rate = NOI / Purchase Price × 100

A higher cap rate indicates higher potential returns but may also indicate higher risk.

Cash on Cash ROI

Measures return on your actual cash invested.

CoC ROI = Annual Cash Flow / Total Cash Invested × 100

This is the most relevant metric for leveraged investments.

Net Operating Income (NOI)

Total income minus operating expenses (before mortgage).

NOI = Gross Income - Operating Expenses

NOI excludes mortgage payments and capital expenditures.

Monthly Cash Flow

Money left over after all expenses including mortgage.

Cash Flow = NOI - Mortgage Payment

Aim for positive cash flow to ensure the property pays for itself.
