If you are buying a short term rental to lower your taxes, the cost segregation study is the line item that turns a normal depreciation schedule into accelerated depreciation and a large first year deduction. So the two questions real estate investors ask us most are simple: what does a cost segregation study cost, and does it pay off on a single Airbnb? This guide answers both with published prices from named providers, the IRS rules on what makes a study hold up, and a break-even test you can run with your CPA before tax season.

New to the strategy itself? Start with our short term rental tax loophole guide, then come back here for the cost segregation details.

Quick Answer: How Much Does a Cost Seg Study Cost?

For a single-family short term rental, the cost segregation study cost published by providers we checked in October 2026 starts around $495 for software-generated reports, while fully engineered studies start at $2,320 to $2,500 at the firms that publish those prices. The final fee depends mostly on the property value (depreciable basis), the property type, renovations, and whether you want a site visit, rush delivery, or audit support. Most firms quote engineered studies per property, so treat any published number as a starting price, not a final quote.

Whether the study pays for itself in tax savings is a separate question. The short version: divide the fee by your marginal tax rate. That is roughly how much extra first year depreciation the study has to find to break even. Compare it with the estimate in a free proposal before you order. The harder questions are whether you can actually use the loss against this year's taxes and how long you plan to hold the property.

Published Cost Segregation Study Prices (Named Providers)

We only list prices that providers publish on their own pages. We have no relationship with any of these companies, and prices change, so confirm on the provider's site before you order. Checked October 2026.

A few details from those pages matter when you compare them. R.E. Cost Seg limits its Rapid Report to residential properties under 3,500 square feet per unit, up to 4 units, with a depreciable basis under $1.2 million. Cost Seg EZ limits its DIY tier to residential properties (excluding condos) under $1 million with under $10,000 of renovations, and sells audit protection as a $195 add-on on its lower tiers. DIY Cost Seg's own site says traditional studies start at $5,000 or more, but at least one engineering firm on this list publishes fully engineered residential studies starting under half that, so do not assume an engineered cost segregation study costs five figures for a single home.

Engineering-Based vs DIY and Software Studies: What the IRS Says

The cheapest option is tempting, so it helps to know how an IRS examiner reads a cost segregation report before you decide how a cost segregation study should be prepared. The IRS publishes a Cost Segregation Audit Techniques Guide (Publication 5653, revised February 2025) to help examiners evaluate studies, and the IRS notes on its Audit Techniques Guides page that the guide is also useful for taxpayers and practitioners preparing them.

Three points from the guide shape the engineering vs DIY decision:

• The IRS has not set a required method. Chapter 3 says the Service "has not established any requirements or standards for the preparation of cost segregation studies." A software report is not automatically invalid.
• Methods are not equal. The guide describes six approaches. It calls the detailed engineering approach from actual cost records "the most methodical and accurate," says the residual estimation approach can be less accurate, and tells examiners to view the "rule of thumb" approach, which applies a fixed percentage with little documentation, with caution.
• Who prepares it matters. Chapter 4 lists 13 principal elements of a quality cost segregation study and says that, in general, a study by a construction engineer is more reliable than one by someone with no engineering or construction background. For acquired (used) property, it says studies should be performed by qualified appraisers and should properly allocate the price between non-depreciable land, the building, and personal property, and that a quality study includes a site visit with photographs.

In practice that gives you a spectrum. DIY tools rely on your inputs and a model. Engineer-reviewed and "rapid" studies add a professional review of a modeled result. Fully engineered studies add a virtual or in-person inspection, measured quantities, and unit costs for building components. The more expensive the property and the bigger the deduction you plan to claim, the more the extra documentation is worth. Your CPA signs the return, so ask which cost segregation study type they are comfortable defending.

What Drives the Price of a Cost Segregation Study

Across the published pricing pages above, the same handful of factors move the fee:

• Property value or depreciable basis. Cost Seg Smart keys its fee to purchase price bands. R.E. Cost Seg defines property value as depreciable basis: what you paid plus improvements minus allocated land value. Higher basis, higher fee.
• Property type and unit count. Single-family homes and condos sit in the lowest tier. Duplexes through fourplexes cost more, and 5+ unit buildings usually move to commercial pricing.
• Square footage and complexity. R.E. Cost Seg says the final fee on its engineered study varies with square footage, property type, and complexity.
• Renovations. A major renovation adds construction costs to classify. Tier limits like "renovations under $10,000" or "under $100,000" push larger projects into higher priced study types or add-ons.
• Inspection. Virtual inspections are often included in engineered studies. In-person visits typically cost extra; Cost Seg Smart lists a $595 in-person residential visit add-on.
• Speed. Rush fees can apply near tax deadlines. Cost Seg Smart lists a $495 24-hour rush option, and R.E. Cost Seg notes rush pricing may apply depending on capacity.
• Audit support and extras. Check whether audit support is included or sold separately, what it covers, and whether a Form 3115 for prior years costs extra.

Is Cost Segregation Worth It for a Short Term Rental?

Here is the break-even logic we walk through with buyers. None of it is tax advice or a substitute for your CPA's projection, but it tells you whether the conversation is worth having.

Step 1: The break-even deduction

Divide the all-in cost segregation study cost by your marginal federal tax rate. The result is roughly how much additional first year depreciation the study must produce to cover its own cost out of first year tax savings. Federal brackets run from 10% to 37% (IRS tax brackets). Using the published prices above:

• An $895 study at a 32% bracket needs about $2,800 of extra first year deductions.
• A $2,320 engineered study at a 24% bracket needs about $9,670.
• A $2,500 engineered study at a 37% bracket needs about $6,760.

These are arithmetic, not predictions of what a study will find. A furnished STR usually has furniture, appliances, carpet, and site work, which IRS Publication 527 lists as 5 year property (appliances, carpets, furniture used in rental property) and 15 year property (roads, shrubbery, fences). How much of your price lands in those classes is exactly what the study determines. Your CPA should also tell you how the study fee itself is treated on your return, which can lower its real cost.

Step 2: Can you use the loss this year?

Accelerated depreciation deductions only lower this year's taxes if the loss can offset other income, so the real tax savings depend on your tax situation. For a W-2 earner that usually means the property qualifies for the STR loophole: an average guest stay of 7 days or less and material participation by you (more than 100 hours and more than any other individual, or more than 500 hours). If you hire a full-service manager who out-logs you, or otherwise fail the hours test, the losses are passive and get suspended until you have passive income or sell. They are not lost, but the study's payoff gets pushed out. Our material participation guide covers the hours tests in detail. Very large losses can also run into the excess business loss limit in Section 461(l).

Step 3: How long will you hold the property?

Cost segregation mostly moves depreciation deductions earlier; it does not create new ones. When you sell, depreciation recapture applies, and gain tied to depreciated personal property is generally taxed as ordinary income (IRS Publication 544). The tax savings are most valuable when you hold long enough for the money you kept (and the extra cash flow) to work for you, or when your bracket at sale is lower than your bracket today. A 1031 exchange can defer recapture. Selling within a year or two shrinks the benefit.

Step 4: Which bonus depreciation rate applies?

The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for qualified property acquired after January 19, 2025, ending the phase-down set by the Tax Cuts and Jobs Act. Treasury and the IRS issued interim guidance in Notice 2026-11. Under the Tax Cuts and Jobs Act of 2017, the 100% rate applied through 2022 and then stepped down each year (26 U.S.C. 168(k)), so property acquired on or before January 19, 2025 stays on that schedule, for example 40% for property put into service in 2025. Two details to raise with your CPA:

• Acquisition date. Under the written binding contract rules the notice applies, the acquisition date can be the later of the contract date, the date cancellation periods end, or the date contingencies are satisfied, not simply the closing date.
• Elections. For property placed in service in the first tax year ending after January 19, 2025, the law lets taxpayers elect 40% instead of 100%, and you can elect out of bonus depreciation for a class of property if a smaller deduction fits your tax planning better.

The building structure itself never qualifies for bonus depreciation, and land is never depreciable.

When cost segregation makes less sense

• The losses will be passive for years and you have no passive income to absorb them.
• You expect to sell soon, so recapture arrives before the deferral pays off.
• The land share of the price is high, so there is little depreciable basis to reclassify.
• Your income this year is low, so each dollar of deduction saves little in taxes.
• The home only works on paper because of the deduction, with weak cash flow once the tax savings are spent.

Cost Segregation on a Short Term Rental or Airbnb: What Gets Reclassified

Cost segregation only applies to property used in a business or held to produce income, not a personal residence, so heavy personal use of a vacation home can limit the benefit. A cost segregation analysis on a short term rental sorts what you paid into land, land improvements, the building structure, and personal property. In a furnished Airbnb, the short-life buckets usually include furniture, appliances, carpet and some finishes (5 year), dedicated electrical that serves equipment, and land improvements like driveways, fencing, landscaping, patios, and pools (15 year). The building structure and structural components such as plumbing, HVAC, and the roof stay on the long schedule. Many CPAs use a 39 year life for an STR with an average stay of 7 days or less rather than 27.5 years; confirm the class life with yours.

Watch for double counting, a spot where many owners slip. Furniture and equipment you buy separately after closing are already short-life assets on your books, so tell the provider what you bought and what came with the house. R.E. Cost Seg's FAQ makes the same point about renovation costs already expensed or depreciated: they should not go into the study again.

Timing: Order Your Study Before Tax Season

Depreciation starts when the property is placed in service, meaning ready and available for rent (IRS Publication 946). For a calendar-year taxpayer, that means listed and bookable by December 31 for the deduction to reduce this year's taxes.

• Order soon after closing. Published turnarounds range from same day for software reports to 3 to 4 weeks for fully engineered work, and R.E. Cost Seg warns that timelines can stretch during peak tax season.
• Collect documents now. Closing statement, purchase contract, appraisal, county appraisal district land and improvement values, renovation invoices, and a furniture list.
• Know the extension option. Form 4868 extends the time to file (not to pay) to October 15, which gives the study and your CPA more room.
• Missed a year? A cost segregation study on a home you started renting in prior years can still catch up missed depreciation through a change in accounting method (Form 3115 with a Section 481(a) adjustment), which the audit guide discusses. Bonus depreciation eligibility still depends on when the property was acquired.

Questions to Ask Any Cost Segregation Company

Use the audit guide's quality elements as a checklist before you pay:

1. Who prepares and reviews the study, and what are their engineering or construction credentials?
2. Which methodology do you use, and does the report describe it?
3. Is there an inspection (virtual or in person), and are photos kept as evidence?
4. How do you allocate land vs building, and does the report reconcile total allocated costs to the total price paid?
5. What does audit support include? R.E. Cost Seg, for example, says its audit support is a written response on methodology and classifications, not representation before the IRS.
6. Are revisions, renovation analysis, and a Form 3115 included or extra?
7. Do you offer a free preliminary analysis of estimated tax savings before I commit?

Texas and Florida Buyers: Where the Math Starts

One of the biggest drivers of a cost segregation study's results is something you control before you buy: the land to building split. Two homes at the same price can produce very different results, and very different taxes owed, if one sits on an expensive lot. Your county appraisal district (Texas) or property appraiser (Florida) publishes separate land and improvement values, and your CPA and cost seg provider will make the final land allocation.

Cost Segregation Study Cost FAQ

How much does a cost segregation study cost for a single-family Airbnb?

For residential property, published prices from the providers above start at $495 for software reports and from about $2,320 to $2,500 for fully engineered studies, before add-ons like rush delivery or in-person visits. Residential real estate is the cheapest tier at every firm we checked.

How does a cost segregation study work?

The provider breaks the property purchased into its parts and assigns class lives to each one. Reclassifying assets such as furniture, appliances, certain components of the electrical system, and site work like fencing, patios, or parking lots moves them from the long building schedule into shorter recovery periods. The rest of the real property stays on the building schedule. The building type, age, and finishes decide how many short-life assets the study can identify, which is also where good providers identify opportunities a quick estimate misses.

What are the benefits of cost segregation on a short term rental?

Of the potential benefits, the biggest is accelerating deductions into the first year, which can reduce current tax liability and free up cash. Dollars you keep today are worth more than the same dollars years from now (the net present value argument), and that increased cash flow can fund furniture, reserves, or the next property. The tax impact still varies a lot. First year tax savings and long-run federal income tax savings depend on your tax bracket, whether the loss is usable, and recapture at sale, so the result can be significant tax savings or very little. Ask your CPA to model your income tax savings with and without a study.

Can I do a cost segregation study myself?

You can buy a DIY software report, and the IRS has not mandated a specific method. The audit guide does say studies by preparers with engineering or construction expertise, plus construction cost knowledge and tax expertise, are generally more reliable, so match the study type to the size of the deduction you plan to claim.

Do CPAs do cost segregation studies?

Most CPAs use the results of a study from a specialist firm, enter the depreciation schedules on your return, and fit it into your broader tax planning strategy alongside other tax strategies. Ask your CPA which providers they have worked with and trust.

How long does a cost segregation study take?

From the published turnarounds above: same day to a few days for software and modeled reports, and roughly 3 to 4 weeks for fully engineered studies once the provider has your documents.

Is cost segregation worth it if I do not qualify for the STR loophole?

It can still make financial sense over a longer hold, because suspended passive losses carry forward. Real estate professional status is another path to non passive rental losses, but it requires more than 750 hours a year and more than half of your working time in real estate trades, which rules out most full-time W-2 earners (IRS Publication 925). Without either, the benefit arrives later, so the break-even math is weaker in year one.

Is this tax strategy only for commercial property?

No. Cost segregation is common in commercial real estate, and studies on commercial property cost more, but the same rules apply to a single furnished STR, and published residential pricing now starts in the hundreds of dollars. For income producing real estate of any size, it is a tax strategy that makes more sense the higher your bracket and the longer you hold. Property owners comparing real estate investments should weigh it as part of the deal, not an afterthought, and property owners already holding a rental can still order one.
