Cost segregation has become one of the most talked-about tax strategies in real estate investing, especially since 100% bonus depreciation was made permanent for qualifying property placed in service after January 19, 2025. That surge in interest has also brought a surge in providers, from national engineering firms to boutique specialists to software-driven DIY tools. Two names that come up often in investor conversations are MVO Cost Segregation and R.E. Cost Seg. Both are legitimate, IRS-focused providers, but they’re built around different models, and that difference matters depending on what kind of property owner you are.
The Short Version
R.E. Cost Seg has built its brand around scale and visibility, its founder is a frequent presence on real estate podcasts and investor forums, and the firm markets a flat, self-service “Rapid Report” priced for volume. MVO takes a different approach: a boutique, tiered model (DIY, Engineer-Reviewed, and Fully Engineered) where the same senior engineer personally reviews every report regardless of which tier a client chooses. For owners who want a single point of accountability and a service level that scales with the complexity of the property, rather than a one-size-fits-most report, MVO is generally the better fit.
| Category | MVO Cost Segregation | R.E. Cost Seg |
|---|---|---|
| Service tiers | Three tiers: DIY, Engineer-Reviewed, and Fully Engineered, so pricing and depth scale with property complexity | Two tiers: a self-service Rapid Report and a Fully Engineered Study |
| Report oversight | Every report, including DIY tier, is personally reviewed by the firm’s lead engineer (15+ years of experience) | Rapid Report tier is modeling-based with less individualized engineering review; Fully Engineered tier adds detailed review |
| Property scope | Short-term rentals through complex commercial and multifamily properties | Broad range of property types, with particular focus on residential and STR investors |
| Site visits | Virtual video inspection standard, in-person for larger/complex projects | Also offers virtual/remote options for qualifying properties |
| Audit support | Included at no additional cost on Fully Engineered studies; add-on for DIY | Included at no additional cost with studies |
| Track record claim | 1,100+ studies completed; states 100% IRS acceptance rate | 15,000+ studies completed; markets a high Net Promoter Score |
Pricing, Tier by Tier
Both firms publish tiered pricing, and the actual dollar figures tell a more useful story than the marketing copy around them.
| Tier | MVO Cost Segregation | R.E. Cost Seg |
|---|---|---|
| Entry-level / DIY | $595 flat, residential under $1M cost basis, minimal renovations, instant self-serve report | No pure self-serve DIY tier offered |
| Mid-tier | $895 flat “Engineer Reviewed,” residential under $1M basis with up to $100K in improvements, engineer-refined, 3–5 business days, audit protection add-on ($195) | $950 starting “Rapid Report,” residential up to 4 units under $800K basis and $50K in capex, no site visit, 5–10 business days, audit support included |
| Fully Engineered | Starting at $2,500, scoped to property; any property type or basis; virtual or in-person inspection; audit support included | Starting at $2,800 (residential) / $3,325+ (commercial); virtual site inspection; 15–20 business days; audit support included |
At every comparable tier, MVO’s published starting price is lower, and its entry tier ($595) has no direct equivalent at R.E. Cost Seg, which has no self-serve option below its $950 Rapid Report. The tradeoff: R.E. Cost Seg bundles audit support into its mid-tier by default, while MVO’s Engineer Reviewed tier treats it as a $195 add-on. Whether that add-on matters depends on how likely a given property is to draw IRS attention in the first place; for straightforward residential assets, it’s a smaller factor.
Turnaround Time
| Tier | MVO | R.E. Cost Seg |
|---|---|---|
| Entry / DIY | Instant (self-serve inputs, ~15 minutes to complete) | N/A |
| Mid-tier | 3–5 business days | 5–10 business days |
| Fully Engineered | Not publicly specified; scoped per property | 15–20 business days (rush option available at 5 business days, capacity-dependent) |
MVO’s mid-tier report turns around faster than R.E. Cost Seg’s comparable Rapid Report, which matters most for owners racing a tax deadline.
Audit Support and Track Record
Both firms describe audit support similarly: written responses to IRS inquiries about methodology and classifications, tied to their engineering documentation. R.E. Cost Seg’s published terms are more specific about what’s excluded (no representation before the IRS, no expert witness testimony, no amendment of returns), which is worth knowing regardless of which provider you choose, since “audit support” as an industry term rarely means full legal representation.
On track record, the numbers get murkier and are worth treating with some skepticism from both firms. MVO’s own site states 1,100+ studies completed with a 100% IRS acceptance rate, while at least one third-party roundup cites a much higher figure (3,000+ studies, $7 billion in client savings) that we could not independently verify and that conflicts with MVO’s own published number. R.E. Cost Seg’s studies-completed figure also varies by source, from roughly 10,000 to 15,000+, and it advertises a sub-0.1% audit rate with a 100% success rate defending the audits that did occur. None of these figures come from an independently audited source, so treat all of them, from both firms, as self-reported marketing claims rather than verified statistics.
Which Provider Fits Which Owner
| Owner Profile | Better Fit | Why |
|---|---|---|
| Single simple STR or rental, basis under $800K, no renovations | Either, MVO on price | MVO’s $595 DIY tier undercuts R.E. Cost Seg’s $950 floor for the simplest cases |
| Residential property with $50K–$100K in improvements | MVO | MVO’s Engineer Reviewed tier covers up to $100K in improvements at $895; R.E. Cost Seg’s Rapid Report caps improvements at $50K before requiring the Fully Engineered tier |
| Multiple properties, wants one consistent reviewer across all of them | MVO | Same lead engineer reviews every report regardless of tier |
| Found cost segregation through a BiggerPockets/STR investing forum thread | R.E. Cost Seg | Deep community presence and STR-specific content; likely already familiar with the brand |
| Large commercial or complex mixed-use asset | Depends on scope | Both offer Fully Engineered studies for this; get quotes from both since final pricing is scoped individually |
| Wants the fastest possible mid-tier turnaround | MVO | 3–5 business days vs. 5–10 for R.E. Cost Seg’s Rapid Report |
Where MVO Pulls Ahead
A single expert reviews every report
MVO’s founder, Andrew, personally reviews every study the firm produces, regardless of tier. That’s a meaningfully different model than a firm that routes lower-cost reports through automated modeling with lighter human review. For an owner who wants a real engineer’s judgment behind the numbers an accountant will eventually file, that consistency is a real differentiator, not just a marketing line.
Pricing and depth actually scale together
Because MVO offers three distinct service tiers instead of two, owners aren’t forced to choose between an oversimplified flat-rate report and a full-scale engineered study with a much higher price tag. A mid-tier, Engineer-Reviewed option exists specifically for properties that are too complex for a pure DIY tool but don’t need the full site-visit treatment.
Boutique means direct access, not a call queue
MVO describes itself as intentionally small, a team structure that tends to mean shorter response times and a consistent point of contact through the engagement, rather than being routed through a larger firm’s account pipeline.
To Be Fair to R.E. Cost Seg
R.E. Cost Seg is a well-established, reputable name in this space, not a fly-by-night operation. Its scale (15,000+ studies) and its founder’s visibility across investor communities have made it something close to the default recommendation on many short-term-rental investing forums, and that reputation is earned rather than purely marketed. Its flat-rate Rapid Report is genuinely useful for straightforward, lower-complexity residential properties where an owner mainly wants speed and a predictable price. For an investor with a single simple STR and no unusual circumstances, that self-service model can be a perfectly reasonable choice.
Methodology: More Similar Than Different
It’s worth noting that on the core technical methodology, these two firms aren’t actually far apart. Both rely on engineering-based component analysis rather than a flat percentage-of-purchase-price shortcut, both classify assets under MACRS per IRS Rev. Proc. 87-56, and both structure reports to align with the IRS Cost Segregation Audit Techniques Guide. Neither firm has a proprietary methodology that meaningfully outperforms the other on paper; the real differences are in service structure, pricing thresholds, and turnaround, not in the underlying tax science.
Frequently Asked Questions
Does a cheaper study mean a lower-quality report?
Not necessarily. MVO’s lower entry price reflects a smaller property/complexity scope at that tier, not a shortcut on methodology. The same is true of R.E. Cost Seg’s Rapid Report.
Can I switch tiers mid-process if my property turns out to be more complex than expected?
Both firms structure their intake to route more complex properties toward the Fully Engineered tier; neither firm’s public materials describe a formal “upgrade” process, so this is worth confirming directly with either provider before starting.
Does audit support mean the firm will represent me before the IRS?
No, for either firm. Published terms from R.E. Cost Seg explicitly exclude formal representation and expert witness testimony from standard audit support; MVO’s public materials don’t detail exclusions to the same degree, so this is a good question to ask directly before signing.
Do these firms serve properties outside the U.S.?
No. Both operate under U.S. IRS depreciation rules (MACRS, Rev. Proc. 87-56) and serve U.S. property owners only.
Bottom Line
For most property owners outside of the simplest, most cookie-cutter single-family STR scenario, yes: MVO’s tiered structure and consistent senior-engineer review give it an edge, particularly for owners with multiple properties, renovations, new construction, or commercial assets where a flat-rate model starts to strain. The combination of boutique-level attention with pricing that doesn’t jump straight to a five-figure engineered study is the practical advantage that matters most.
Where R.E. Cost Seg’s Rapid Report may still make sense is for an investor who owns one simple, unremarkable rental property and just wants the fastest, lowest-friction path to a report. Outside of that narrow case, MVO’s model is built to handle more of what real properties actually look like.
