Depreciation: What Investors Actually Keep
Depreciation is one of the most powerful — and most misunderstood — mechanics in commercial real estate investing.
It isn’t cash flow.
It isn’t a distribution.
And it doesn’t increase money in the bank.
Depreciation is a tax deduction. But that deduction can materially change what investors keep after taxes — especially in stabilized assets and value-add strategies.
Before we begin, a quick disclaimer: this discussion is educational in nature. I am not a CPA, tax attorney, or tax professional. Tax rules vary by investor and by deal, so any real-world decisions should be made with guidance from your own tax advisors.
In this article, we’ll walk through depreciation in six parts:
What depreciation is — and what it isn’t
The land versus building rule
Standard depreciation schedules
Cost segregation and accelerated depreciation
Bonus depreciation and timing
Depreciation recapture at exit
Let’s start with the fundamentals.
What Depreciation Is — And What It Isn’t
Depreciation is a non-cash expense that allows real estate owners to deduct the cost of a building over time.
The logic behind it is simple: buildings experience wear and tear. The tax code allows owners to gradually deduct that loss of value over a defined period.
The important takeaway is this:
Depreciation can reduce taxable income without reducing actual cash flow.
Consider a simple example.
Imagine an industrial building generating $200,000 in annual net income. The owner doesn’t necessarily spend that entire amount maintaining the building that year — the cash remains real.
However, depreciation allows a deduction associated with the building’s aging. That deduction may significantly reduce the amount of income reported for tax purposes.
That’s why depreciation is often called a paper expense. It affects taxes, not the cash balance.
The Land vs. Building Rule
A critical rule in real estate taxation is that land cannot be depreciated.
Only the building and certain improvements qualify.
When a property is acquired, the purchase price must be allocated between:
Land value
Building value
Only the building portion becomes the depreciable basis.
For example:
A retail center is purchased for $5 million. An appraisal allocates $1.5 million to land and $3.5 million to the building.
Depreciation is calculated based on the $3.5 million building value, not the full purchase price.
This allocation matters because two investors can purchase the same asset at the same price and still end up with different depreciation outcomes depending on how the land and building values are determined.
Standard Depreciation Schedules
In the United States, depreciation generally follows long, predictable schedules.
Residential rental property — including multifamily — is typically depreciated over 27.5 years.
Most commercial property — office, retail, and industrial — is depreciated over 39 years.
This predictability allows investors to model depreciation during underwriting.
For example, imagine acquiring an apartment building with an $11 million depreciable basis.
Dividing that over 27.5 years results in approximately $400,000 of annual depreciation.
While exact figures vary, this estimate provides a strong directional understanding of after-tax performance.
Depreciation becomes especially relevant when properties produce meaningful cash flow.
Case Study: Cash Flow vs Taxable Income
Consider a multifamily acquisition with the following structure:
Purchase price: $12 million
Land allocation: $2 million
Building allocation: $10 million
The property generates $900,000 in net operating income.
After debt service, annual equity distributions equal $400,000.
Now consider depreciation.
$10 million of building basis depreciated over 27.5 years produces approximately $364,000 in annual depreciation.
So investors receive $400,000 in real cash distributions, but depreciation offsets much of the taxable income associated with that cash.
This is why two investments with identical cash-on-cash returns can produce very different after-tax results.
Cost Segregation: Accelerating Depreciation
Now we introduce cost segregation.
Cost segregation is an engineering-based analysis that identifies building components that can be depreciated faster than the standard 27.5 or 39-year schedule.
Instead of treating the entire structure as one asset, the study separates certain elements into shorter-lived categories such as:
Appliances
Flooring
Fixtures
Certain site improvements
These components may qualify for depreciation schedules of 5, 7, or 15 years.
Why does this matter?
Because it accelerates deductions into earlier years.
Consider a value-add apartment acquisition where the sponsor renovates 60% of units.
During the renovation phase, cash flow may be uneven due to construction costs and leasing downtime.
A cost segregation study might identify assets eligible for faster depreciation, increasing deductions during those early years.
This doesn’t increase total depreciation over the life of the property — it simply pulls deductions forward in time.
And timing is often what matters most to investors.
Bonus Depreciation and Timing
Bonus depreciation allows certain qualifying assets to be expensed immediately, rather than depreciated over time.
In real estate, bonus depreciation often applies to the shorter-lived property identified through cost segregation.
For example:
A sponsor invests $1.5 million in renovations during the first year of ownership.
A cost segregation study identifies $900,000 of qualifying shorter-life assets.
Without bonus depreciation, those assets would depreciate over 5–15 years.
With bonus depreciation, a portion of that amount may be deducted immediately.
If bonus depreciation is 40%, then approximately $360,000 could be expensed in year one.
This can significantly increase early-year deductions.
That’s why bonus depreciation is frequently discussed in value-add strategies, where early operational instability coincides with high renovation spending.
However, timing is critical.
The key phrase is “placed in service.”
Assets must be ready and available for their intended use for depreciation to apply. If improvements are completed later than expected, depreciation timing shifts accordingly.
This is why sponsors carefully document renovation completion dates and coordinate closely with tax professionals.
Depreciation Recapture at Exit
Depreciation creates tax efficiency during ownership, but it has consequences at exit.
This is known as depreciation recapture.
Here’s the concept.
When depreciation deductions are taken, the investor’s tax basis in the property decreases.
That lower basis increases the taxable gain when the asset is eventually sold.
Consider this example:
Purchase price: $12 million
Building basis: $10 million
Total depreciation over five years: $2 million
If the property sells for $16 million, the gain is not simply the difference between sale price and purchase price.
Instead, the gain is calculated using the adjusted basis.
Adjusted basis = purchase price minus depreciation.
So:
$12 million purchase price
– $2 million depreciation
= $10 million adjusted basis
Now the taxable gain becomes:
$16 million sale price – $10 million basis = $6 million gain
Without depreciation, the gain would have appeared to be $4 million.
The additional $2 million represents previously claimed depreciation deductions returning into the tax calculation.
Managing Depreciation Strategically
Institutional investors manage depreciation strategically as part of full-cycle underwriting.
Several approaches are commonly used.
One is long-term hold strategies, which emphasize tax efficiency during ownership and reduce the frequency of taxable exit events.
Another is refinancing, which allows investors to access liquidity without triggering a sale.
Another approach involves tax-deferral strategies such as 1031 exchanges, where proceeds are rolled into new investments under strict rules.
The key insight is that depreciation improves after-tax performance during the hold period — but recapture must be understood as part of the exit.
Pre-Tax Returns vs After-Tax Outcomes
Consider two hypothetical deals.
Deal A distributes $450,000 per year, but offers limited depreciation benefits.
Deal B distributes $400,000 per year, but generates substantial accelerated depreciation.
On a pre-tax basis, Deal A appears stronger.
But after taxes, Deal B may leave investors with more money in their pockets.
That’s why institutional capital evaluates after-tax outcomes, not just headline yield.
Final Thoughts
Depreciation is one of the defining mechanics of real estate investing.
To recap:
Depreciation is a non-cash deduction tied to the building, not the land
Land allocation affects the depreciable basis
Standard schedules are 27.5 years for residential and 39 years for commercial property
Cost segregation accelerates certain components into shorter schedules
Bonus depreciation can shift deductions into early years
Depreciation recapture affects taxation at exit
The most important takeaway is this:
If you underwrite deals based only on pre-tax returns, you are missing a meaningful part of the investment outcome.
Depreciation strategy — including cost segregation and bonus depreciation — can materially shape what investors actually keep.
