Cost Segregation Under $5,000: Why Studies Don't Have to Break the Bank
Technology has fundamentally changed the economics of cost segregation. Here is what every price tier actually delivers.

For decades, cost segregation was reserved for institutional investors and large commercial property owners. Traditional engineering firms quote $5,000 to $15,000 per study. If your rental property is worth $400,000, an $8,000 study fee eats nearly half the potential tax savings. That pricing barrier locked out most real estate investors, the landlords with one to ten properties, the W-2 earners who bought their first duplex, the short-term rental operators running an Airbnb. Two things changed the economics. Automated data collection removed most of the manual hours from a small study, and a handful of providers started pricing on the engineering work required rather than on the property's value. Engineer-signed studies now start at $1,200. This guide covers what every price tier actually delivers, how to tell a real study from a template, and how to decide whether cost segregation is worth it for your property.
Cost Segregation Options by Price Tier
Free: Online Calculators
Our free cost segregation calculator provides instant estimates based on real data from thousands of completed studies. Use this to screen whether cost segregation is worth pursuing before spending any money. If the calculator shows less than 5x ROI, cost segregation may not be justified for your property. This is an estimate for decision-making only, not a study you can claim on your tax return.
$495 to $1,000: DIY Software (No Engineer)
Reports generated by entering property details into software that applies generic allocation percentages. Published entry rates in this tier run from about $495 (DIY Cost Seg lists $495 to $995 for residential buildings up to four units) up to roughly $2,500 for commercial reports. No engineer reviews the output and no one signs it. The IRS Cost Segregation Audit Technique Guide (Publication 5653) devotes a full chapter to the principal elements of a quality study, including a preparer with expertise in cost estimating and an explanation of the methodology used. A template allocation with no named preparer meets neither. The accuracy-related penalty under IRC Section 6662 adds 20% to any resulting underpayment. This tier can be a reasonable screening tool. It is not a filing position on a property where real money is at stake.
$1,200 to $6,000: Engineer-Signed, Technology-Enabled Studies
This is the right tier for most rental and small commercial property owners. These studies combine modern data tools (property records, satellite imagery, construction cost databases, and owner-provided photos) with licensed engineer analysis. The engineer reviews every classification and signs the report. You receive a complete depreciation schedule your CPA can use directly, plus audit defense coverage. What changed is where the hours go, not whether an engineer does the work. Automating the data gathering does not shorten the classification analysis, which is the part the IRS actually examines.
Here is our own fee structure, set by the engineering work a property requires. Property type comes first because it determines how many asset classes an engineer has to analyze, then building size sets the scope inside that class. The property's market value is not an input.
| What the engineer has to analyze | Our fee | Traditional firm range |
|---|---|---|
| Residential and small property. Single-family, condo, short-term rental, 2 to 4 unit multifamily. Standard residential systems, simple site improvements, no tenant fit-out. | $1,200 - $2,500 | $3,000 - $9,000 |
| Standard commercial. Office, retail, restaurant, self-storage, warehouse, 5 to 20 unit multifamily. Commercial systems, landlord and tenant asset splits, substantial site work. | $2,500 - $6,000 | $5,000 - $25,000 |
| Large and complex. Hotel, 20+ unit apartment complex, large industrial. High fixture and equipment density, amenity spaces, multi-building site improvements. | $6,000 - $12,000 | $12,000 - $60,000 |
Every fee in the left column buys the same thing: a licensed engineer on the classification work, a signed report, and audit defense. There is no cheaper tier below $1,200 because there is no version of this that skips the engineer. Traditional firm ranges are the fee schedules those firms publish or quote, compiled from Patrick Accounting, Engineered Tax Services, and a 2026 multi-firm pricing comparison. Above the top band, complex assets are quoted individually.
What This Looks Like as ROI
The study fee is small relative to the deduction it unlocks, which is why the return holds up across property sizes. These figures assume an 80% building to land ratio, a 24% accelerated allocation, a 35% combined marginal rate, and 100% bonus depreciation, which applies to property acquired and placed in service after January 19, 2025. Your numbers will differ.
| Single-family rental | Our fee | Est. year-1 savings | Net | ROI |
|---|---|---|---|---|
| $350K purchase price | $1,200 | ~$23,500 | ~$22,300 | 20x |
| $500K purchase price | $1,200 | ~$33,600 | ~$32,400 | 28x |
| $750K purchase price | $1,200 | ~$50,400 | ~$49,200 | 42x |
| $1M purchase price | $1,500 | ~$67,200 | ~$65,700 | 45x |
Notice that the fee barely moves across the first three rows while the savings triple. That is what work-based pricing looks like. The engineering effort on a $750K single-family rental is close to identical to the effort on a $350K one, so the fee is close to identical too. Firms that price on property value produce the opposite pattern, and we break that down in how cost segregation pricing really works.
$5,000-$15,000+: Traditional Engineering Firms
A physical on-site inspection by an engineer who photographs every component, reviews construction blueprints, and prepares a detailed asset-by-asset classification. This is the original cost segregation methodology and remains the gold standard for highly complex or high-value properties. Best for large commercial properties ($10M+), specialized buildings (hospitals, manufacturing, data centers), and situations where institutional partners require on-site documentation. Turnaround is typically 6-12 weeks.
When Cost Segregation Is NOT Worth It (At Any Price)
I will also tell you when cost segregation does not make sense. If your depreciable basis is under about $150,000 with limited site improvements, the accelerated deduction is often too small to justify any paid study, including ours at $1,200. If you are in a low bracket (under 22%), the dollar value of the deduction shrinks and the payback stretches out. If your rental losses are passive and you have no passive income to offset, the deduction may sit suspended for years rather than cutting this year's bill, which is the single most common reason a study disappoints. If you plan to sell within one to two years, depreciation recapture on sale offsets most of the timing benefit. And a study is a timing strategy, not free money: it accelerates deductions you would have taken anyway. For a detailed analysis, see our guide on when cost segregation does not make sense.
