Investment Margin Protection Framework

What Cap Rate Does

Calculates the annual yield of an investment property assuming it is purchased entirely with cash, dividing Net Operating Income (NOI) by the Purchase Price.

Why Cap Rate Matters

Normalizes mortgage variables out of the equation so you can compare property performance across different geographical regions and neighborhoods.

3 simple steps

Underwriting Action Strategy

1

Calculate Gross Revenue

Combine rental income and additional revenue streams like laundry or parking fees.

2

Deduct Net Expenses

Subtract vacancy allowances and operating costs to determine Net Operating Income (NOI).

3

Divide by Price

Divide NOI by purchase price to instantly output the property's Cap Rate percentage.

Most investors lose money here — avoid these mistakes:

  • Confusing Cap Rate with Cash-on-Cash Return (which factors leverage).
  • Excluding property management costs from NOI calculations.
  • Buying low cap rate deals in high-risk areas without safety margins.
