Comparing Seneca Cost Segregation vs Titan Echo means choosing between two ways of getting a cost segregation study done. Seneca is an engineering firm that hands you a finished study, while Titan Echo is a software platform, backed by its own engineers, that lets an owner or CPA take on part of the work.
As co-founder of Seneca Cost Segregation and a multifamily investor in the Pacific Northwest myself, I hear the do-it-yourself question often. The question usually comes from a CPA deciding whether to bring cost segregation in-house, or from an owner wondering whether walking the building is worth the savings, and the answer tends to turn on how many hours each is prepared to spend.
Below is a side-by-side look at both options. Seneca wrote this comparison, so every Titan Echo detail comes from Titan Echo’s own website as of October 2026, and the cases where Titan Echo is the better choice are laid out plainly.
TL;DR — Seneca vs Titan Echo at a Glance
Here is how the two options differ in practice, based on what each one publishes.
- ●Seneca hands you a finished study: its team does the tour, engineering, and legal analysis, and delivers in 5 to 10 business days when documents come back promptly.
- ●Titan Echo lets you split the work: $25 a month buys estimates, training, and engineer support, and you can do the field work while Titan’s engineers estimate costs.
- ●Small buildings split the two most: Titan Echo’s EchoLite model covers buildings under $500,000 of basis, and Titan Echo says it does not meet every IRS Audit Techniques Guide requirement on its own.
- ●You can price both first: Seneca’s estimate and proposal are free, with payment only if you move forward, and a Titan Echo Matrix estimate shows Titan’s fee up front.
- ●Audit terms differ in writing: Seneca adds a 100% fee refund to its audit defense if a Seneca-caused issue drives an adjustment above 5%, and Titan Echo offers free remote audit support.
- ●Speed is worth money under current law: property acquired and placed in service after January 19, 2025 qualifies for 100% bonus depreciation, so most reclassified basis is deductible in year one.
Seneca Cost Segregation vs Titan Echo Side by Side
The table pulls each option’s published terms into one view. Seneca details come from its client records and website; Titan Echo details come from titanecho.com.
Both describe their work as engineering-based. The real split is who performs each step, which shapes cost, timing, and how the report holds up under review.
How Seneca Cost Segregation Delivers a Study
Seneca does cost segregation and nothing else, and every step of a study, from the first estimate to the final report, stays with its in-house team across all 50 states.
An Engineer-Built Estimate Before Any Commitment
Each engagement starts with a free preliminary savings estimate and proposal, which Seneca’s engineering team builds from the details the owner shares about the property. The owner pays only after deciding to go ahead.
Fully engineered residential studies start at about $2,000 and scale with the property. Commercial studies are priced to the complexity of the building and typically start at $3,500.
Onsite or Virtual Tours Run by Seneca’s Team
Once the owner signs on, Seneca collects a few documents and schedules the tour. Owners choose between an onsite visit, which many commercial owners prefer, and a guided virtual property tour, which suits most residential properties.
Either way, Seneca’s people do the field work, and the owner gets real-time updates as the study moves through each defined stage. Studies run 5 to 10 business days for residential and commercial properties alike, provided the owner returns documents and tour access promptly.
One Review Standard and Head of Engineering Sign-Off
Every Seneca report passes through the same internal review, and the Head of Engineering signs off on each study before it goes to the CPA. The deliverable is a PDF report and fixed asset schedule with a component breakdown of everything that makes up the property.
Seneca also runs Qualified Production Property (QPP) studies. The team has assessed 10,200+ properties covering more than $5 billion of cost basis, with an average first-year deduction of $171,000.
How Titan Echo Works
Titan Echo is a cost segregation platform built by Titan Engineering, a Denver, Colorado company that began developing it in 2014 and delivered its first cost segregation projects in early 2015. Titan Echo says it was originally built so CPA firms could bring cost segregation in-house instead of outsourcing it to consultants.
Platform Access for $25 a Month
Access costs $25 a month with no annual contract. Subscribers get unlimited Matrix benefit estimates, the Echo Learning Academy training course, and remote support from Titan’s engineers.
A Matrix estimate projects additional depreciation, tax savings, and return on investment, along with what Titan would charge for its share of the study. Titan Echo does not publish a turnaround time, and its FAQ declines to share sample reports on the grounds that every property is different.
Three Components of Scope You Can Split
Titan Echo divides a full study into three Components of Scope:
- ●On-site verification: the field work, which the user can perform after training, recording dimensions, items, and photos in the Echo mobile app.
- ●Construction cost estimating: Titan’s engineers quantify each component and its cost, then prorate the total back to what was paid for the property.
- ●Legal analysis: classification of each item under cost segregation law, handled by the user’s CPA or tax attorney, or by Titan.
An owner who wants a turnkey study can direct Titan to handle all three, and the finished Echo Report includes a completed Form 3115 when a catch-up is needed. For a wider look at the category, Seneca’s guide to cost segregation software options covers when a platform makes sense.
EchoLite for Properties Under $500,000
For smaller projects, Titan Echo offers EchoLite, an empirical model drawn from data on its completed studies, sold at a one-time flat fee. A building qualifies only if its basis after removing land is under $500,000 and no later improvements are added to the project.
Titan Echo is candid about the limits. Its own guidance says the EchoLite calculation is not a substitute for a full cost segregation study because, by itself, it does not meet all the requirements of the IRS Audit Techniques Guide.
Key Differences Between Seneca and Titan Echo
Both options chase the same deduction, so the decision comes down to five practical differences.
Who Does the Work
With Seneca, the owner supplies documents and tour access, and Seneca’s team does the rest. With Titan Echo, the owner or CPA chooses which components to take on, and any part they keep becomes their work to complete and stand behind.
That flexibility is the center of Titan Echo’s pitch; the company says no one else in the category sells partial scope. For an owner with one or two properties, the hours spent learning the method and walking the building belong in the price.
Total Cost of a Study
Titan Echo’s direct cost is $25 a month plus a project fee that falls when the user takes on more of the scope, and Titan cites $3,000 to $15,000 as a typical study range. A Seneca study is a single fee, starting at about $2,000 for residential and typically $3,500 for commercial, quoted for free before the owner commits.
Field time, training, and any CPA hours on legal analysis carry a cost that never appears on an invoice. Seneca’s breakdown of cost segregation study pricing walks through what drives a quote.
Turnaround Time
Seneca delivers in 5 to 10 business days for every property type, complex commercial included, once it has what it needs from the owner. Titan Echo publishes no standard timeline, and a do-it-yourself study also depends on when the user can schedule and finish the site visit.
Timing carries more weight now that P.L. 119-21 restored 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025. For a purchase closing late in the year, a published timeline makes planning easier.
Treatment of Smaller Properties
Seneca runs the same engineered process on every property, with no fixed basis cutoff. Its work ranges from small single-family rentals in the Midwest to multi-million-dollar mansions, small self-storage facilities, 40,000+ square foot office buildings, 120+ unit hotels, and multi-million-dollar manufacturing plants.
Titan Echo routes smaller buildings toward EchoLite, and Seneca’s comparison of engineered and rule-of-thumb methods explains why the method behind the numbers matters if a return is examined.
Audit Protection
Seneca AuditDefense comes with every study, so Seneca answers IRS questions about the report it produced. A written term adds a 100% fee refund if an audit finds that a Seneca-caused issue led to a depreciation adjustment above 5%, and Seneca’s overview of why audit defense matters explains the coverage.
Titan Echo provides remote audit support at no additional cost for platform projects and reports a 100% success rate in IRS audits. Where the user performed the site work or the legal analysis, ask Titan in writing how that support applies to the portions it did not prepare.
What Doing the Site Work Yourself Involves
Titan Echo describes on-site verification as the easy part of a study and the most expensive part to outsource. We see this framing consistently from owners and CPAs, and the reality of field work is more demanding than that.
In Titan Echo’s process, the user walks the property in three sections (site improvements, structure, and interior) and must finish all three before the engineers begin estimating costs. Anything the walk misses never reaches the cost estimate, so it cannot be reclassified.
The IRS Cost Segregation Audit Techniques Guide recommends a field inspection for all quality studies, and the first of its 13 principal elements is preparation by an individual with expertise and experience. Titan Echo pairs user field work with training and engineer review, so the practical question is whether you want to own that step.
Who Should Pick Seneca Cost Segregation
Seneca makes the most sense for owners who want the study done for them on a known schedule.
- ●You want a finished study: the owner’s role is documents and access, and Seneca’s team handles every component.
- ●You are working against a deadline: a 5 to 10 business day turnaround, with prompt replies from the owner, fits a filing date.
- ●Your property is small: every building gets a fully engineered study, without a switch to a statistical model below a basis threshold.
- ●You want written downside protection: audit defense is included, and the refund term covers adjustments above 5% caused by Seneca.
- ●You want one direct team: a dedicated Project Manager, the Engineering team, and an Advisor stay with the owner and CPA from estimate to delivery.
Who Should Pick Titan Echo
Titan Echo suits a different reader, most often a CPA firm or a hands-on, repeat investor.
- ●A CPA firm building a service line: Titan Echo was built for firms that want to offer cost segregation themselves, with engineers behind them on cost estimating.
- ●Frequent deal screening: unlimited Matrix estimates for $25 a month help someone evaluating many properties before buying.
- ●Owners who want to do the walk: an investor comfortable with field work can take on the site visit and reduce Titan’s share of the fee.
- ●Very simple small buildings: where the CPA accepts a modeled result, EchoLite offers a flat-fee route for basis under $500,000.
Questions to Ask Before You Choose Either Option
The ATG’s principal elements double as a buyer’s checklist, whether a firm or a platform produces the study. When we prepare an estimate at Seneca, we expect the owner’s CPA to test it against exactly these points.
- ●Who prepares each part: name the person or team responsible for the site visit, the cost estimate, and the legal analysis.
- ●How field data is captured: ask whether the inspection is onsite or virtual and which photos and measurements are recorded.
- ●Whether a model or engineering applies: confirm whether the result comes from a full study or a statistical estimate.
- ●How costs tie out: the guide expects total allocated costs to reconcile to total actual costs.
- ●What the full price is: get every fee in writing, including subscriptions and per-project charges.
- ●What audit support covers: ask for the terms in writing and how they apply to any work you performed yourself.
- ●What your CPA receives: confirm the report format and whether a Form 3115 and Section 481(a) schedule come with it.
