We work with your accountant, and we don’t over-engineer our studies or push the limits of the IRS. It’s an approach that appeals to property owners – large and small.

Do you need a cost segregation study?

Most real estate owners know the value of depreciation, but few take full advantage of the benefits.
Why? There are several reasons:

Many owners are simply unaware of the magnitude of the potential benefits.

Most owners and accountants are unable to extract the appropriate cost information from the contractor’s project documents.

The building was purchased long after it was built and the original cost information no longer exists.

A Cost Segregation Study addresses these deficiencies and enables the property owner to take full advantage of accelerated depreciation, reduced tax liability, and increased cash flow.

FAQ's

A cost segregation study is a specialized engineering and tax analysis that separates and reclassifies property assets into shorter depreciation categories.

By identifying assets like lighting, flooring, and mechanical systems separately from the building structure, you can accelerate depreciation deductions and significantly reduce taxable income.

Cost segregation is ideal for:

  • Commercial property owners

  • Multi-family real estate investors

  • Industrial facility owners

  • Residential rental property owners

  • Developers and builders

If you own a property valued at $500,000 or more, a cost segregation study could unlock substantial tax savings and cash flow increases.

At CostSeg Northwest, our typical study timeline is:

  • 2–4 weeks for existing buildings

  • 4–6 weeks for large or highly complex new construction

We handle coordination directly with your contractor and CPA to streamline the process.

Properties that typically see the greatest ROI from cost segregation include:

  • Office buildings

  • Apartment complexes

  • Industrial facilities

  • Retail centers

  • Hotels and resorts

  • Medical offices

  • Manufacturing plants

  • Warehouses and distribution centers

Almost any income-producing property qualifies for accelerated depreciation.

Yes. Even if you purchased a property up to 15 years ago, you may be eligible for a look-back study.

Through the IRS’s automatic Form 3115 change, you can catch up missed depreciation without amending prior returns — delivering a major cash flow boost in the current year.
