What cost segregation looks for
Where earlier deductions
can add up.
The opportunity is in qualifying costs that can move to shorter depreciation schedules. These are three areas we examine closely; the largest opportunity depends on what your property contains and how much cost is allocated to each asset.
1
Appliances, carpeting & furnishings
Residential rental appliances, carpeting, and furniture generally use a 5-year schedule. Identifying their costs separately can bring deductions forward instead of leaving them in the building’s basis.
2
The connections serving equipment
Dedicated wiring and certain plumbing hookups may qualify with the equipment they serve. We trace their function and cost; general building wiring and plumbing are treated differently.
3
Paving, landscaping & site improvements
Qualifying parking areas, walkways, fencing, and landscaping often use a 15-year schedule. Extensive site work can represent a meaningful pool of costs to review.
Residential example shown. Walls, roofs, built-in cabinetry, and general building systems typically remain on the building schedule; land is not depreciable. Commercial asset lives depend on use and classification. IRS rental property guide · Classification examples
What makes an area high impact?
The dollars assigned to qualifying assets, how much sooner they can be deducted, and your ability to use those deductions. Our study documents the first two; your tax preparer evaluates how they affect your tax return.

Asset classifications, cost allocations, depreciation schedules, and documentation supporting the methodology. Your tax preparer reviews the report and determines how the deductions apply to your return.

Yes. Alongside residential rentals, we take on commercial properties and larger short-term rental investments, including properties above $5 million. Scope and fees are confirmed individually.
Does the calculator work for every property?
The instant calculator is a residential screening tool. Commercial, hospitality, and complex properties need an individual review. An estimate is not a completed study or a determination of the deduction you can use.
