Cost Segregation for Rental Property Owners: What to Look for in a Provider

Whether you own a duplex in Salt Lake City, a single-family rental in Utah County or a cabin near Midway or Park City, depreciation is one of the most valuable tax benefits of owning rental property. A cost segregation study can help you claim more of it sooner. But the study is only as good as the firm that prepares it, so choosing a provider deserves the same care as choosing a property.

What a cost segregation study does

Residential rental buildings are generally depreciated over 27.5 years. A cost segregation study looks inside the building and identifies components that qualify for shorter recovery periods, such as appliances, carpeting, certain cabinetry and dedicated electrical work (often 5 or 7 years) and site improvements like driveways, fencing and landscaping (often 15 years).

Moving those costs onto faster schedules increases your deductions in the early years of ownership. With 100% bonus depreciation now permanent for qualifying property acquired after January 19, 2025, many of those components can be deducted in the year the property is placed in service.

Gather your records first

A provider can only work with what you give it. Before you request quotes, pull together:

• Your closing statement and purchase contract.

• The property tax assessment, which can help support the split between land and building.

• Invoices and receipts for renovations, appliances and furnishings.

• Photos, floor plans or an inspection report.

• Your current depreciation schedule from your CPA.

Land can't be depreciated, so how the purchase price is divided between land and building matters. A good provider will explain how it supports that allocation rather than accept an arbitrary percentage.

Use reviews the right way

Reviews help you understand what working with a firm is actually like. A detailed R.E. Cost Seg review can show how a specialist describes its process, pricing and deliverables, and an independent review of R.E. Cost Seg gives you a second perspective on the same firm. Reading more than one source makes it easier to spot consistent strengths or recurring concerns.

Apply the same approach to every firm you consider. Look for comments about report quality, communication and support after delivery, not just star ratings.

What to look for in a provider

The IRS explains what it expects from a quality study in its Cost Segregation Audit Techniques Guide. Use those expectations as your checklist:

• Qualified preparers: a team with both construction or engineering knowledge and tax expertise.

• A documented methodology: a clear explanation of how costs were identified and classified.

• Reconciled costs: allocated amounts that add up to your total basis.

• Rental experience: familiarity with residential properties like yours, not only commercial buildings.

• CPA coordination: a willingness to answer your tax preparer's questions directly.

• Clear pricing: a written scope that states what is included, including any support if the IRS asks questions.

Bought a while ago? You may not be too late

If you have owned a rental for several years without a study, you may still benefit. A change in accounting method filed on IRS Form 3115 can let you claim depreciation you missed in earlier years as a current-year deduction, without amending prior returns. Ask providers whether they offer look-back studies.

Check that the deductions fit your situation

Bigger deductions are only useful if you can use them. Rental losses are often passive, which can limit when they reduce your taxes, and faster depreciation can increase recapture when you sell. Talk through your holding period and income with your CPA before you commission a study. If your rental is a short-term or cabin property, also review local rules, as in this guide to buying a Bear Lake cabin, and check Utah HOA rules that can limit rentals.

The bottom line

A cost segregation study can meaningfully improve the cash flow from a rental property. Gather your records, read reviews from more than one source and choose a provider whose work meets the standard the IRS uses to evaluate studies. Also keep an eye on Utah's 2026 housing laws as you plan your investments.
