What Should a Cost Segregation Study Actually Cost? The 2026 Pricing Transparency Report

I have personally engineered, reviewed, or quality-checked over 1,000 cost segregation studies across every major property type. I have worked inside technology-enabled platforms, alongside traditional engineering firms, and with solo practitioners. I have seen the invoices, the engagement letters, and the internal pricing models. And I can tell you with certainty: the way most cost segregation firms price their studies has almost nothing to do with the actual engineering work involved.

This article is the pricing transparency report I wish existed when I started in this industry. I am publishing our actual fee table, comparing it against every major firm type, and explaining, with data, why cost segregation pricing is broken and what a fair price actually looks like. No one has published this before. The industry benefits from opacity. I do not.

Why Cost Seg Pricing Is Broken

The fundamental problem with cost segregation pricing is that most firms price based on your property's value, not the engineering work required to analyze it.

Think about what that means. A 2,000 square foot single-family rental in Phoenix worth $350,000 requires the same engineering analysis as an identical 2,000 square foot single-family rental in a coastal market worth $1,200,000. Same floor plan. Same components. Same number of line items in the depreciation schedule. Same engineering hours. On a value-keyed fee schedule, those two owners land in different pricing tiers anyway. I am not going to put a single round multiple on that, because the honest answer depends on which firm you ask. Look at the published schedules further down this page and do the division yourself.

This is value-based pricing. The firm calculates your estimated tax savings, determines what percentage you would "happily" pay to receive those savings, and sets the fee accordingly. That is rational from the firm's perspective. It is irrational from an engineering perspective.

What actually drives engineering effort

After 1,000+ studies, I can tell you exactly what determines how much work a study requires:

1. Asset class. A hotel has fundamentally different building systems than a single-family home. More component types = more classification work.
2. Building size (gross square footage). Larger buildings have more systems, more zones, and more line items to classify. A 180,000 sq ft office building requires meaningfully more analysis than a 5,000 sq ft office.
3. Construction complexity. A ground-up build with full cost records is different from a 1970s renovation with no documentation.
4. Renovation scope. If a Form 3115 change in accounting method is needed, that is additional tax and engineering work.
5. Inspection requirements. On-site inspections add real cost (travel, time, equipment).

Notice what is not on that list: property value. A $300,000 townhouse and an $800,000 townhouse in different markets require the same engineering analysis. The components are the same. The depreciation schedules are the same. The only thing that changes is the dollar amount assigned to each component, and that is arithmetic, not engineering.

How Different Firms Actually Set Prices

Having worked across the industry, I have seen four distinct pricing models. Each reveals something about the firm's incentives.

Model 1: Value-Based Pricing (Most Traditional Firms)

The firm estimates your tax savings, then charges a percentage, typically 10-20% of first-year benefit. On a $2M property with $60,000 in estimated first-year savings, the study fee lands at $6,000-$12,000. On a $500K property with $18,000 in savings, the fee is $3,000-$5,000. The engineering work is nearly identical, but the fee doubles.

Why firms use this model: It maximizes revenue on high-value properties while maintaining a "reasonable ROI" narrative. The pitch is always: "You will save $60,000 and only pay $8,000, so that is a 7.5x return." True, but irrelevant to what the work actually costs to deliver.

Model 2: Hourly Billing (Large Engineering/Accounting Firms)

Some large regional engineering and accounting firms bill the work by the hour rather than quoting a fixed fee. The number of hours is the whole story, and it is where the money goes: junior engineer time on component takeoff, senior review, report writing, and administrative overhead all land on the invoice.

The hidden problem: Hourly billing incentivizes inefficiency. There is no motivation to automate pattern recognition when every manual hour generates revenue. I have seen firms bill 40 hours for work our automation handles in minutes, not because the work is complex, but because a junior engineer is manually categorizing carpet, cabinets, and parking lot striping line by line.

Model 3: Contingency/Success-Based Pricing

Some firms charge nothing upfront and take 15-25% of your actual tax savings. This sounds attractive ("you only pay if it works") but it creates a dangerous incentive: the more aggressively they classify your property, the more they earn. I have reviewed studies from contingency-fee firms that classified 45-50% of a standard apartment building to accelerated depreciation. Our benchmark data from 8,000+ studies shows the median for apartments is 24%. Those aggressive classifications are audit magnets.

Model 4: Asset-Class + Size-Based Flat Fee (Our Model)

We price based on what actually determines engineering effort: the asset class and building size. A townhouse costs the same whether it is worth $300,000 or $900,000. A 180,000 sq ft office building costs more than a 5,000 sq ft office, because it genuinely requires more analysis. This is how engineering should be priced.

2026 Market Pricing Data: What Investors Actually Pay

I compiled pricing data from three sources: our internal database, published firm rate cards, and 200+ investor-reported costs from BiggerPockets forums, Reddit (r/realestateinvesting, r/ShortTermRentals, r/AdvancedTaxStrategies), and real estate investor communities. Here is what the market actually looks like as of April 2026.

Residential Properties (Single-Family, Small Multi-Family, Condos)

Source: Modern CFO internal data (1,000+ studies), BiggerPockets forum analysis (120+ reported prices), Reddit investor communities (80+ reported prices), published firm rate cards (40+ firms). Data collected January through April 2026.

Commercial Properties (Office, Retail, Industrial, Hospitality)

What investors report paying on forums

The forum data is revealing. On BiggerPockets, the most common complaint is sticker shock. One investor with a $1.4M property in Los Angeles reported being quoted $7,500 for a single study, and noted that only one of three firms even responded to their inquiry. Another investor on Reddit's r/ShortTermRentals asked for "ballpark numbers" on a $1.2M duplex and received estimates ranging from $3,000 to $8,000 depending on the firm. A BiggerPockets Pro member with a large apartment portfolio reported paying approximately $8,000 per study for "full engineering" on multi-million dollar assets.

The pattern across 200+ forum reports is consistent: investors with properties under $1M feel priced out of traditional engineering firms, and many are choosing between (a) overpaying at $5,000-$8,000, (b) settling for a non-engineering desk study at $1,500-$3,000, or (c) skipping cost segregation entirely. None of these are good outcomes.

Our Pricing Matrix: Full Transparency

I am going to do something most cost segregation firms do not: publish the fee table. Three bands, set by the engineering work a property requires. Property type comes first, because it determines how many asset classes an engineer has to analyze. Building size sets the scope inside that band. The property's market value is not an input.

Above the top band, complex assets are quoted individually. There is no band below $1,200. Every fee in that middle column buys the same thing: a licensed engineer on the classification work, a signed report, and audit support. Traditional firm ranges are what those firms publish or quote for the same property classes.

Where you land inside a band

Two properties in the same band are not always the same price. Inside each band, building size and component density move the fee between the low and the high end. A 1,400 sq ft single-family rental sits at the $1,200 floor. A 4-unit building with detached garages and extensive site improvements sits higher in the residential band. A 6,000 sq ft retail strip prices near the bottom of the commercial band, and a 180,000 sq ft office building prices near the top of it.

How size moves the fee

Optional add-on fees

• Renovation analysis (Form 3115): $600 base ($400 minimum upon request). Required when claiming missed depreciation from prior years
• Renovation addition: $240 when applicable, for properties with significant renovation scope requiring additional component analysis
• Partial Asset Disposition (PAD): $400, for properties where demolished or replaced components can generate additional deductions
• On-site inspection: $800 minimum, for properties requiring professional physical inspection (booked outside 10 business days; expedited inspections subject to travel surcharges)
• Multi-study discount: Automatic 10% for 2+ studies in a single engagement, up to 20% maximum

What a Fair Price Actually Looks Like

Based on 1,000+ studies and analysis of the full market, here is my framework for what a cost segregation study should cost, regardless of provider:

If you are paying above the "Overpaying" column, you are subsidizing a firm's overhead, not paying for better engineering. If you are paying below the "Suspect Quality" column, ask hard questions about whether a licensed engineer actually reviews the output. The 12-question provider checklist is a good starting point.

The DIY and Desk Study Trap

I understand the appeal of a DIY cost segregation report at a few hundred dollars. I also understand why some investors choose a $1,500 to $3,000 CPA desk study. Both are cheaper than engineering-based studies. Both will produce a depreciation schedule. And both share a structural weakness: neither identifies a preparer the way Publication 5653 describes, so both carry materially more audit risk. I am not going to tell you a desk study always fails on examination, because that depends on the examiner, the property, and how aggressive the allocation was. What I will say is that the first of the guide's 13 principal elements is preparation by an individual with expertise and experience, and a template allocation with no named preparer does not satisfy it.

The IRS Cost Segregation Audit Technique Guide (Publication 5653) is explicit. It identifies six methodologies for cost segregation, ranked by rigor. The "Detailed Engineering Approach from Actual Cost Records" is the gold standard. The "Rule of Thumb Approach" is the weakest. DIY software and most CPA desk studies fall into the bottom two categories.

As one experienced investor noted on BiggerPockets: a full engineering study on a large apartment complex costs about $8,000 and "will almost certainly pass an audit." More affordable alternatives using statistical or rule-of-thumb methods "may make financial sense, but there is more audit risk." That is the trade-off, and it is one most investors do not fully understand when they choose the cheapest option.

I wrote a detailed assessment of DIY cost segregation that covers exactly where self-service breaks down. The short version: if no named engineer reviews and signs your study, you are taking on audit risk that could cost multiples of what you saved on the study fee. Negligence penalties under IRC Section 6662 add 20% to any underpayment.

Pricing Red Flags That Signal a Bad Study

After reviewing studies from dozens of firms, these pricing patterns consistently correlate with lower-quality work:

ROI Analysis: When Any Study Pays for Itself

The ultimate question is not "how much does the study cost?" but "what is the return on that cost?" Here is the ROI math at our pricing versus traditional firm pricing, using our benchmark median of 24% accelerated allocation and a 37% federal tax bracket with 100% bonus depreciation, which applies to property acquired and placed in service after January 19, 2025 (restored under the One Big Beautiful Bill).

Assumptions: 80% building-to-land ratio, 24% median accelerated allocation (from our 8,000+ study benchmark), 37% marginal federal tax rate, 100% bonus depreciation on property acquired and placed in service after January 19, 2025. State taxes would increase savings further. Actual results vary by property. Our fee shown is the fee for the most common property class at that size: a single-family rental up to $1M, a 5 to 20 unit multifamily at $2M, and a mid-size commercial building at $5M. A hotel or a 20+ unit apartment complex at the same basis sits in our large and complex band instead.

Why the Work-Based Fee Comes Out Lower

The honest answer is technology plus a different pricing basis. Our workflow was built around automated data collection from day one rather than retrofitted onto a manual process, and we price the engineering scope instead of the property value. Here is what that means in practice:

1. 80% of cost segregation is pattern recognition. Identifying carpet as 5-year property, parking lot as 15-year property, and structural framing as 39-year property is not engineering judgment. It is classification against known IRS rules. Our AI handles this instantly using training data from 1,000+ completed studies.
2. 20% requires genuine engineering judgment. Unusual construction methods, specialty building systems, edge-case classifications, and properties with complex renovation histories. That is where I and our engineering partners spend our time. We do not automate judgment. We automate the work that does not require it.
3. We only partner with AI-forward engineers. Every engineer in our network uses our technology platform. This means faster turnaround, lower per-study cost, and consistent quality. We do not work with firms that insist on doing everything manually.
4. Zero overhead. No corner offices. No administrative layers. No partner profit expectations. No cross-selling pressure. Our entire business is cost segregation, delivered efficiently.

The result: you get the same IRS-compliant, engineering-based study a $15,000 traditional firm delivers, priced to the work it takes. Same report format. Same audit defense. Same named engineer reviewing every classification. The only difference is how we get there.
