Left alone, this building faced 27.5 years.
The standard treatment is blunt: one building, one asset, 27.5 years, and done. Applied to a $2,815,000 multifamily property in Lexington, that meant deductions dripping out at roughly $102,000 a year while the owner waited.
That default is not a mistake, it is just the floor. What most owners never hear is that the same tax code offers a different reading. Under MACRS, a property is not one thing depreciating in lockstep. It is many components, and the shorter-lived ones were never meant to sit on the 27.5-year line.
The whole game is which reading you use. One leaves the money parked for decades. The other frees a real piece of it in year one. The dollars are identical. Only the timing changes, and timing is the entire point.
An apartment community is many assets, not one.
A multifamily property depreciates over 27.5 years by default, but a community is far more than its walls: it is unit interiors at scale, appliances and finishes in every unit, and extensive site work across the whole complex.
The Cost Seg America team analyzed this property the way the two engineering approaches the IRS ranks highest call for: component by component, across the whole property. Not a questionnaire, not a software estimate that runs the address through a template and returns an average. An actual engineering analysis of the structure, the site work, and the systems that a cheaper study never bothers to separate.
What an engineered study looks for in a property like this
- Unit interior finishes and flooring, repeated across every unit in the community.
- Appliances and cabinetry serving individual units.
- Site work and land improvements: parking, drives, walkways, site lighting, landscaping, pools, and amenity areas.
- Dedicated electrical and plumbing serving unit systems beyond the base structure.
The result: $1,123,203, roughly 40% of the property's basis, was identified as shorter-life property and moved off the 27.5-year schedule into faster federal depreciation. That is not an estimate or a projection. It is what an engineered analysis documented on this building, to the standard the IRS publishes for its own examiners in the Cost Segregation Audit Techniques Guide.
Deductions are worth more now than later.
A study like this does not conjure deductions out of thin air. Every dollar of that $1.1M always belonged to the owner. The study simply pulled those deductions forward, out of the distant future and into the present, where each one carries more weight.
The logic is plain. A dollar deducted this year beats a dollar deducted in 2050, because this year's dollar can go back to work, into the next deal, into the business, into anything that earns. Inflation chips away at the far-off deduction; time value rewards the near one. Moving $1.1M forward is an interest-free head start the code hands out on purpose.
And the timing has rarely been better. Under the One Big Beautiful Bill Act, signed July 4, 2025, 100% bonus depreciation is now permanent for qualifying property placed in service after January 19, 2025. The shorter-life property an engineered study pulls out is exactly what qualifies, so reclassified value like this can land as a first-year deduction instead of leaking out over decades.
What accelerating $1.1M is worth.
Reclassifying property is only half the story. The other half is what those accelerated deductions are worth once they are working for you now instead of decades from now. The figures below are illustrative, calculated from this study's real reclassified amount using the assumptions shown.
Illustrative first-year federal tax benefit: $415,585. Illustrative 10-year net present value of accelerating: $314,181.
Illustrative only, not a promise of results. First-year benefit assumes the $1.1M of reclassified property is deducted in year one under 100% bonus depreciation (permanent under the One Big Beautiful Bill Act for qualifying property placed in service after January 19, 2025) at a 37% federal tax rate. Net present value compares taking those deductions now versus the default schedule, discounted at 8% over 10 years. Federal figures only. Your actual benefit depends on your tax situation; your CPA determines what applies to you.
What owners ask about a result like this.
Could a study like this be done on a building I bought years ago?
Yes. A look-back study reaches properties bought, built, or renovated as far back as ten years. Your CPA files one form, Form 3115, with the regular return, and the depreciation you should have taken already comes back as a single catch-up deduction this year, figured as a Section 481(a) adjustment. No amended returns, no reopened years.
Does a reclassification like this invite an audit?
Cost segregation is a recognized, IRS-documented practice with its own examiner guide, Publication 5653. If a return is examined, what carries the day is the quality of the study behind it. Every Cost Seg America study is built on the two engineering approaches that guide ranks highest, and the team's work has cleared more than 125 IRS audits with zero losses and nothing returned.
What happens to these deductions when the property sells?
Depreciation figures into a sale whether or not a property was cost segregated, and your CPA plans for it. For owners who hold for years, the value of large deductions taken now generally outweighs the treatment at sale, and a 1031 exchange can defer it. It is a planning matter, never a reason to leave the deductions unclaimed.
Would my building reclassify the same 40%?
Not necessarily. The share that reclassifies turns on how the building was built and fitted out and how much site work surrounds it, which is why results vary widely. The only way to know your figure is an engineered analysis, and a free proposal will estimate it before you spend anything.
