Ask 10 real estate investors to explain depreciation, and you will get 10 different answers. Some will get it mostly right, while others will confuse it with something else entirely. A few will admit they just let their CPA handle it and have never really dug into how it works.
That is more common than you might think, and it’s also a real missed opportunity. Depreciation is one of the most significant tax advantages available to real estate investors, and understanding it at a basic level makes you a sharper investor, regardless of how many units you own.
What Depreciation Actually Means
In plain English, depreciation is the IRS’s acknowledgment that physical assets wear out over time.
A building is not going to last forever. The roof will eventually need replacing. The plumbing ages. The structure itself has a finite useful life. Because of this, the tax code allows property owners to deduct a portion of their property’s value each year to account for gradual wear and tear.
Think of it like this. If you buy a piece of equipment for your business that has a 10-year lifespan, you can deduct one-tenth of its cost each year rather than writing off the whole thing up front. Real estate works the same way, just on a longer timeline. You paid a certain amount for the property, and the IRS lets you spread that cost out as a deduction over the course of several decades.
One important note: Land does not depreciate. You can only depreciate the structure itself, not the dirt under it. When calculating depreciation, the land value gets separated from the building value, and only the building portion counts.
