CostSegEZ Review (2026)

Pricing, methodology, audit support, and where this DIY platform fits.

Editorial note: Cost Segregation Reviews is operated by Cost Seg Smart, which appears as one option among many on this site, including in this review. Public-facing data only — pricing, methodology, and credentials reflect what CostSegEZ publishes on its own site. Reviewed September 2026.

CostSegEZ is a Princeton, New Jersey-based DIY cost segregation platform sold in three tiers rather than one flat product: a $595 self-serve DIY report, an $895 Engineer Reviewed report, and a Fully Engineered study starting at $2,500. Every tier applies MACRS classification under Rev. Proc. 87-56 to sort building components into 5-, 7-, 15-, and 27.5/39-year property — the same federal classification framework every provider works within — but the three tiers differ in who reviews the output before it reaches the client and whether the property qualifies at all: the DIY and Engineer Reviewed tiers publish a $1 million value cap and residential-only scope, while Fully Engineered adds commercial property with no stated cap. Cost Seg Smart prices a comparable sub-$300,000 residential property at $495 as a single engineer-reviewed, CPA-ready deliverable, without a separate paid tier to add review.

Pricing detail

DIY: $595. Engineer Reviewed: $895. Fully Engineered: starts at $2,500. A $195 Audit Protection add-on is available on the DIY and Engineer Reviewed tiers; the site states lifetime audit protection is included at no extra charge with Fully Engineered.

What you get

The DIY tier is a self-serve, instant report generated from information the customer enters, with no stated professional review before delivery. The Engineer Reviewed tier adds a review step, delivered in 3-5 business days. The Fully Engineered tier is described as the firm's most complete offering — a 3-4 week turnaround with an in-person site-visit option — and is the only tier that opens up to commercial property.

Methodology basis

CostSegEZ describes its approach as an "engineering-based methodology" with an "engineer-led process," applying MACRS classification consistent with Rev. Proc. 87-56 across all three tiers. The site also states a "100% IRS acceptance rate" and a "No Studies Rejected" claim; this is the vendor's own marketing language, not a figure this site has independently verified, and we do not repeat it as a fact of study quality.

Property-type fit

DIY and Engineer Reviewed cover residential property up to a published $1 million value cap. Commercial property is served only through the Fully Engineered tier, which the site describes without a stated value cap. An investor with a commercial property below $1 million who wants the lower-cost tiers will not qualify for them on CostSegEZ's own published terms.

Audit support terms

Lifetime audit protection is included with the Fully Engineered tier. On the DIY and Engineer Reviewed tiers, audit protection is a separate $195 add-on rather than a default inclusion. The site does not publish the specific scope of that protection (hours included, representation terms, or a cap on support cost) beyond the add-on price.

Pros

• Three price points let a buyer choose how much review they want to pay for, rather than one fixed deliverable.
• Nationwide operation across all 50 states.
• Fully Engineered tier extends to commercial property with an in-person site-visit option.

Cons

• DIY and Engineer Reviewed tiers cap out at $1 million in property value and residential-only.
• Audit protection costs extra ($195) on the two lower tiers rather than being included.
• The site does not state whether a CPA or a licensed engineer signs the final report on any tier.

Verdict — who this is for

CostSegEZ fits an investor who wants to start cheap and pay more only if they want more review — the tiered structure is unusual among the providers on this site. It is a fit for sub-$1M residential property where the buyer is comfortable choosing their own review level, and for commercial owners willing to pay the Fully Engineered price. It is not a fit for a sub-$1M commercial property, which does not qualify for either lower-cost tier. See our software versus engineered study guide for how a self-serve or lightly reviewed report compares with a fully signed study on documentation depth.
