Most STR Investors Miss Out on Bonus Depreciation — Here’s Why

How Bonus Depreciation Actually Works
for Short-Term Rentals (STR)
Short-term rental owners hear a lot about “bonus depreciation.” Most of what’s out there stops at the headline and misses what actually drives the result.
Yes—bonus depreciation is available.
But the outcome has very little to do with the rule itself. It comes down to how the property is analyzed.
What Bonus Depreciation Actually Applies To
Bonus depreciation allows accelerated write-offs on specific categories:
5-year property (furniture, appliances, fixtures)
7-year property (certain equipment)
15-year property (land improvements—driveways, landscaping, fencing)
It does not apply to the building.
The structure is typically depreciated over:
27.5 years (residential rental), or
39 years (if treated as a lodging/business property)
If a $1M property is purchased and nothing else is done, most of that value gets spread over decades.
That’s where most investors stop—and where most of the opportunity is missed.
Where the Value Actually Comes From
A property isn’t one asset. It’s a collection of components with different useful lives.
Inside the same building:
Flooring
Cabinetry
Electrical
Plumbing
Exterior improvements
Many of these qualify for shorter depreciation schedules.
But nothing gets separated automatically.
If it’s not broken out, it all defaults to 27.5 years.
Cost Segregation Is What Unlocks It
A cost segregation study reclassifies those components.
It reallocates portions of the purchase price into:
5- and 7-year property
15-year land improvements
Those categories are eligible for bonus depreciation.
That’s what allows a meaningful portion of the property to be written off quickly—often in year one.
Why This Is Commonly Done Wrong
This isn’t a simple reallocation exercise.
A defensible cost segregation study is engineering-based.
It involves:
Reviewing construction details
Identifying individual components
Applying IRS-backed classification methods
Done correctly, it takes time and precision.
That effort is what creates the difference between standard depreciation—and a materially different tax outcome.
What Happens Without It
Without the study:
Most of the purchase gets assigned to the building
Depreciation is stretched over 27.5 years
Acceleration is lost
In most cases, the property is treated as a single asset when it isn’t.
Which means the opportunity to accelerate portions of that cost is lost — especially on larger properties.
How to Create Additional STR Leverage
Short-term rentals can change how those accelerated deductions are used.
If structured correctly, they may:
Fall outside traditional rental activity rules
Allow losses to be treated as non-passive
That’s where this becomes more than a timing benefit.
Accelerated depreciation can potentially offset:
Business income
W-2 income
Other active income
But that depends on classification and participation—not just owning the property.
The Actual Strategy
Bonus depreciation isn’t the strategy.
It’s a tool.
The strategy is:
Identifying the right components
Classifying them correctly
Structuring the activity so the deductions are usable
Without that, bonus depreciation exists—but doesn’t move the outcome much.
With it, the numbers can shift materially.
