What is the Income Approach?

The income approach in real estate appraisal values a property based on its ability to generate income, typically used for commercial or investment properties. It involves estimating the property's potential income, deducting vacancies and operating expenses to calculate the Net Operating Income (NOI). The property's value is then determined by dividing the NOI by a capitalization rate, reflecting the expected rate of return.

The income approach typically involves the following steps:

  1. Estimate Potential Income: This includes calculating the potential gross rental income the property could generate when fully leased, along with other possible income sources like parking fees or laundry services.
  2. Account for Vacancies and Credit Losses: The appraiser estimates the amount of income lost due to vacancies or non-payment of rent.
  3. Calculate Effective Gross Income: This is the actual income the property is expected to generate after accounting for vacancies and credit losses.
  4. Estimate Operating Expenses: These are the costs associated with maintaining and managing the property, including property taxes, insurance, repairs, and utilities.
  5. Calculate Net Operating Income (NOI): This is the effective gross income minus operating expenses. NOI represents the income a property would generate before financing and income tax.
  6. Apply a Capitalization Rate (Cap Rate): The cap rate is used to estimate the property's value, reflecting the investor's required rate of return. The NOI is divided by the cap rate to determine the property's estimated value.

The income approach assumes that a property’s value is directly related to its ability to produce income. Thus, it is a fundamental method in the valuation of income-producing properties.
