Executive summary

This study reclassifies a portion of the property's depreciable basis from 39-year nonresidential into shorter recovery periods, accelerating deductions into year one under current bonus depreciation rules.

Basis of this study. This study covers 1509 Palma Vista Ave Unit B, a single-family home placed in service Apr 16, 2013, operated as a short-term rental. The entire property is in scope at 100% business use. Depreciation runs on the 39-year transient-occupancy schedule, applied to a depreciable basis of $251,992 ($62,998 land excluded from $314,990 total). The residual structural shell is classified as 39-year nonresidential real property because the property is operated as transient lodging.

Total deduction
USD297,702
$189,842 is deductible this year, mostly a one-time catch-up for depreciation not taken since Apr 16, 2013, claimed through a Form 3115 your preparer files. The balance comes through over the remaining schedule. That includes $45,710 of furniture, appliances, and fixtures (§1245 personal property) placed in service for the rental.

Section 02

How the asset depreciates

This year's deduction comes from reclassifying short-life property out of the building basis: the 5- and 15-year components take bonus depreciation now, and the rest depreciates on the regular schedule. A catch-up also applies for depreciation under-claimed in prior years.

First-year MACRS depreciation
$5,733 4%
Regular first-year depreciation on the remaining basis, including the 39-year shell (mid-month, partial year).
§481(a) catch-up
$138,399 96%
One-time deduction equal to the cumulative shortfall from prior years' under-claimed depreciation.
Prior-year catch-up: $138,398. One deduction this year for 13 prior years of under-claimed depreciation, claimed via Form 3115 · DCN 7. It is not an additional deduction. The year-by-year table below derives this figure.
Show the year-by-year build-up

For each year since the property was placed in service, this compares depreciation actually taken against what the cost segregation study would have allowed. The cumulative shortfall is the catch-up above.

Furniture, fixtures & equipment: by category

Furnishing the property to operate as a rental is a separate investment from the building. Where receipts weren't kept, Unlevered values each item and depreciates it as 5-year §1245 personal property, a stand-in for the original invoices. It's a separate pool from the building reclassification above, and it's already included in your year-one deduction. Each row shows any written-off basis of a replaced item next to the new property placed in service; expand for the itemized detail.

Section 05

Methodology calibrated to IRS standards

Component allocations follow the IRS Cost Segregation Audit Techniques Guide and MACRS recovery periods. Every assumption traces to a publicly cited authority.

Shell recovery period (IRC §168(e)(2))

The residual structural shell is depreciated as 39-year nonresidential real property. Operated as transient lodging (average guest stay ≤30 days), not residential rental property under IRC §168(e)(2)(A)(ii)(I). The tax use of the property controls the recovery period, not its physical form.

Statutory authority: IRC §168(e)(2)(A)(ii)(I) · IRC §168(e)(2)(B) · IRC §168(c).

Key parameters & assumptions

The figures above are fixed by these study-specific inputs: the bonus rate is set by the placed-in-service and §168(k) acquisition dates, and any disposition is a taxpayer election. They carry through the entire study.

Tax year of filing2026
MACRS recovery periods, conventions, and the bonus rate are applied as in effect for this filing year.
First-year bonus rate0%
IRC §168(k) first-year bonus depreciation. PIS before 2017-09-27, pre-TCJA bonus; V1 does not compute pre-TCJA schedules.
Land allocation$62,998
Land is non-depreciable and excluded from the reclassified basis.
MACRS conventionsMid-month / half-year
The 39-year shell uses the mid-month convention; 5- and 15-year property uses the half-year (or mid-quarter) convention per IRS Pub. 946.
Component takeoff methodModeled engineering estimate
Absent contractor receipts, each component's quantity is modeled from the property's finished area, lot, and photo-confirmed features, priced against a citation-backed relative-cost catalog (RSMeans Residential / Craftsman National Construction Estimator / IRS Cost Segregation ATG), and allocated proportionally to the depreciable basis. The method reproduces an independent third-party engineered study for a comparable property within ~1 percentage point per recovery class. Preliminary, pending field verification.

About this study. Component allocations are cross-validated against IRS authorities, assessor records, and the client's source documents during the preparation workflow.
Preparer & qualifications. This cost segregation study was prepared by Unlevered's engineering review team, whose agents hold expertise in construction cost estimating and federal depreciation tax law. The team supervised the data inputs, reviewed the component analysis, and made the final §1245/§1250 and recovery-period determinations. Unlevered's cost segregation engine is a computational tool used by the preparer, analogous to the commercial estimating software relied on in a traditional engineering-based study, and Unlevered stands behind these results, including in the event of examination. The taxpayer's own tax return preparer is the sole tax return preparer: they review the study, exercise independent professional judgment in adopting its component classifications, and prepare and file the return using their own tax software. Unlevered is not a tax return preparer under IRC §7701(a)(36) and Treas. Reg. §301.7701-15.
