What is Property Depreciation?

Property depreciation refers to a tax deduction that a real estate investor can take over the property’s ‘useful life’. It’s a method to account for the perceived decrease in the value of a property due to factors like aging, wear and tear.

For residential properties, the Internal Revenue Service (IRS) has determined the useful life to be 27.5 years, while for commercial properties, it’s 39 years.

Why is Depreciation Important?

Depreciation is a powerful tool in a real estate investor’s arsenal as it lowers your taxable income, allowing you to save on taxes. By taking the annual depreciation deduction, you’re reducing the amount of income on which you’ll owe taxes.

How to Calculate Depreciation

The most common way to calculate depreciation is the straight-line method. Here’s how it works:

  1. Determine the initial cost of the property (excluding land as it doesn’t depreciate).
  2. Divide the initial cost by the property’s useful life (27.5 years for residential, 39 years for commercial).

This will give you the annual depreciation amount that you can deduct from your taxable income.

The Impact of Cost Segregation on Depreciation

Cost segregation is a tax planning strategy used by real estate investors to accelerate depreciation deductions. In a cost segregation study, certain assets within a building are identified that can be depreciated over a shorter life span (5, 7, or 15 years), instead of the standard 27.5 or 39 years. This results in larger depreciation deductions in the early years of property ownership, reducing current income tax obligations.

The Impact of Depreciation on Investment Strategy

As a real estate investor, understanding and taking advantage of property depreciation can significantly enhance your investment strategy. By lowering your taxable income, you effectively increase your annual return on investment.

Moreover, property depreciation can also be used as a strategy to offset rental income, which can be particularly beneficial for those owning multiple rental properties.


In conclusion, property depreciation is an essential concept that all real estate investors should understand. It can help to significantly reduce your taxable income, effectively boosting your return on investment.
