The best cost segregation study provider for rental property investors
Built to IRS standards
Audit support includedFlat price for every study3 to 5 business days Inherited rental property owners get a cost segregation opportunity that most buyers never see: a full reset to fair market value on the date of death, wiping out whatever depreciation the original owner already claimed. That stepped-up basis under IRC Section 1014 becomes the new starting point for a study, regardless of what the decedent originally paid decades earlier.
- Cost segregation on inherited rental property uses the stepped-up basis under Section 1014, not the original purchase price.
- A $600,000 stepped-up building basis moves roughly $150,000 onto 5-, 7-, and 15-year schedules at a 25% allocation.
- Inherited property does not qualify for bonus depreciation, but the reclassified basis still depreciates far faster than 27.5 years.
- Land value, appraisal timing, and how the property is titled all change the math before you order a study.
Why cost segregation matters for heirs
When someone inherits a rental, the decedent's depreciation schedule dies with them. The heir's basis resets to fair market value as of the date of death (or an alternate valuation date the estate may have elected six months later), and depreciation starts fresh from that new number under Section 1014.
That matters because a property the decedent bought for $200,000 in 1995 and mostly depreciated out could be worth $700,000 today. The heir doesn't inherit the old, used-up depreciation schedule. They inherit a basis that's often several times larger, and a full 27.5-year (or shorter, once reclassified) depreciation clock that starts over. Properties held in a trust pass through this same basis reset when the trust distributes real property to beneficiaries, which is common in estate settlements.
A cost segregation study run on that new basis reclassifies part of the building value into 5, 7, and 15-year property instead of leaving all of it on a 27.5-year residential schedule. Inherited property does not qualify for bonus depreciation, because its basis comes from the value at death under Section 1014. The reclassified portion still depreciates over 5, 7, and 15 years instead of 27.5, which moves much of the deduction into the first few years.
Update your basis calculation first
Before anything else, nail down the number the study will run against.
- Pull the estate's Form 706 valuation or a certified appraisal dated at the time of death
- Separate land value from building value; land never depreciates regardless of basis step-up
- Confirm whether the executor elected the alternate valuation date (six months after death) instead of the date-of-death value
- Keep the appraisal and estate closing documents on file; a study built on the stepped-up basis needs these, not the decedent's original settlement statement
- Loop in the estate's CPA or attorney before ordering a study so the basis figure matches what's reported on the estate tax return
Determine your placed-in-service date
This is where inherited property gets more nuanced than a straight purchase, and the details change your options.
- If the home was already a rental before the death and kept renting without a gap, document when you began managing it as the new owner
- If the property was the decedent's personal residence and you're converting it to a rental, the placed-in-service date is the day it's first available to rent, not the day you inherited it
- Classification, recovery period, and bonus eligibility depend on how the property is actually used and documented going forward, not simply on the fact that it was inherited
- Track lease start dates, listing dates on Airbnb or VRBO, and any renovation timeline separately from the estate paperwork
- Confirm with your CPA whether the property qualifies for short-term rental treatment or standard residential rental treatment based on average guest stay and your participation
Decide how the property is titled among heirs
Multiple heirs on one deed changes how the benefit gets allocated, and it's worth settling before you order anything.
- Confirm whether the property is held as tenants in common, in an LLC, or still inside the estate or trust
- Get ownership percentages in writing; cost segregation deductions typically follow ownership share, not who manages the property day to day
- If heirs plan to sell rather than hold, weigh whether a full study still pencils out against a shorter hold period
- Decide early whether one heir will buy out the others, since that changes whose basis the study should reflect
- Coordinate with each heir's own CPA if they file separately, since passive activity rules can differ by heir's income and involvement
Run the engineering-based study on the new basis
Once the basis, placed-in-service date, and titling are settled, the study itself follows the same process as any residential cost segregation engagement.
- Submit the appraisal, closing or estate documents, and any renovation records
- Expect a site-visit-free process for most residential properties, using photos, floor plans, and public records instead
- A typical engineering-based report separates 5-year (furniture, appliances), 15-year (land improvements like driveways and fencing), and 27.5-year (structural) components
- Review the reclassified percentage against the 25% figure used as a general planning benchmark, understanding actual results vary by property type and condition
- Confirm turnaround expectations with the provider before year-end if you want the deduction to land in the current tax year
“If the estate already stepped up the basis, don't let the decedent's old depreciation schedule anchor your thinking. You're starting over, not picking up where they left off.”
Apply the study and hand off to your CPA
The report itself doesn't get filed with the IRS. It's a supporting document your CPA implements on your return.
- Confirm the placed-in-service date, which starts depreciation on the stepped-up basis. Inherited property is not eligible for bonus depreciation, so the benefit comes from the shorter 5-, 7-, and 15-year recovery periods
- Ask your CPA how the reclassified assets flow onto Form 4562 for the current tax year
- If the property has been in service for a prior year already, ask whether a Form 3115 accounting method change applies instead of amending
- Reconcile the study's asset list against any capital improvements made since the date of death
- Keep the full study on file as audit-defense documentation, separate from the estate's own tax filings
Heirs converting a decedent's former residence into a rental face a similar basis and timing question; the mechanics for converting a home to a rental overlap closely with what's described above.

Comparing your options
| Option | Best For | Key Limitation |
|---|---|---|
| Straight-line 27.5-year depreciation only | Heirs with a small step-up or a short expected hold | Leaves accelerated first-year deductions unclaimed |
| CPA rule-of-thumb allocation | Quick, rough estimates before committing further | Not engineering-based; weaker documentation if audited |
| Engineering-based cost segregation study on the stepped-up basis | Heirs with $300,000 or more in stepped-up building value | Requires gathering appraisal and estate paperwork upfront |
| Doing nothing and filing as-is | Estates settling a single low-value rental with no long-term hold plans | Forfeits accelerated depreciation on the entire new basis |
Verdict: an engineering-based study on the stepped-up basis is the move for any heir holding a residential rental worth $300,000 or more that they plan to keep for a few years, because the basis reset is a one-time event that doesn't repeat.
Common mistakes heirs make
- Using the decedent's original purchase price instead of the stepped-up basis when estimating depreciation, which understates the deduction by a wide margin
- Skipping the appraisal and guessing at a land-to-building split instead of using the estate's actual valuation
- Not checking whether the alternate valuation date was elected, which can change the basis figure the study should run against
- Assuming co-heirs split the benefit evenly without documenting actual ownership percentages on the deed or trust agreement
- Waiting past year-end to order the study and missing the placed-in-service window needed for that tax year's return
FAQ
Does cost segregation work on inherited rental property?
Yes. Inherited residential rentals get a stepped-up basis under IRC Section 1014, and a cost segregation study can reclassify part of that new basis into shorter-life property for accelerated depreciation.
What basis do you use for depreciation on an inherited rental?
You use the fair market value as of the date of death, or the alternate valuation date six months later if the estate elected it, not what the original owner paid.
Does inheriting a rental property reset depreciation?
Yes. The prior owner's depreciation schedule ends, and the heir starts a new depreciation schedule based on the stepped-up basis and their own placed-in-service date.
Can you claim bonus depreciation on an inherited rental?
No. Property acquired from a decedent, with a basis set under Section 1014, does not meet the acquisition requirements for bonus depreciation. A cost segregation study still moves short-life components onto 5-, 7-, and 15-year schedules, so the stepped-up basis depreciates much faster than 27.5 years.
What is the alternate valuation date and does it affect cost segregation?
The alternate valuation date lets an estate value assets six months after death instead of on the date of death, and if elected, that value becomes the basis a cost segregation study should use.
Do multiple heirs each get their own cost segregation study?
Usually one study covers the property, with the reclassified deduction allocated among heirs according to their documented ownership percentage rather than separate studies per person.
How is stepped-up basis different from a 1031 exchange basis?
Stepped-up basis resets to fair market value at death under Section 1014, while a 1031 exchange carries over and adjusts the seller's original basis into the replacement property.
Should you convert an inherited home to a rental before or after ordering a cost segregation study?
Confirm the placed-in-service date first, since classification and recovery period depend on how and when the property is actually put into rental use, then order the study once that date is documented.
One last thing
The basis reset only happens once. If an heir sells the inherited property without running a cost segregation study first, that stepped-up basis and its depreciation potential are gone for good, because the buyer starts their own basis calculation from the purchase price, not from the estate's valuation. For anyone weighing a sale instead of a hold, it's worth checking how the same stepped-up basis interacts with reducing capital gains tax before deciding.
