A situation to compare
You have a five-unit building and are unsure which ordering route applies.
The published residential route covers single-family homes through four units; five or more units use the commercial route. Compare the selected product with the evidence your CPA requires.
For a digital workflow, distinguish an estimate, an automatically generated document and a professionally reviewed final study. Ask which one your preparer needs and how corrections are handled.
Compare the two written proposals
Send both providers the same property description and records. Ask each to identify unsupported assumptions, the review professional and the steps needed before delivery. Choose based on the written work your property requires.
Compare the complete proposal
- What property records, site verification and technical review are included?
- Will the report reconcile basis and explain component classifications?
- Who resolves missing invoices, later improvements and prior depreciation?
- Are Form 3115 preparation, return filing, state adjustments or examination support separately priced?
- Who confirms whether deductions can be used given participation, passive-loss and other limitations?
A projected deduction is not a cash saving. Compare the study fee, filing costs, timing benefit and expected holding period with your preparer before ordering.

Check the official pricing or service source — research 2026-10-13. Published starting fees are not property-specific quotes and can change.
Which product and fee apply to the unit count, and are corrections, concierge work and audit support separate? Compare the study, inspection, corrections, technical support and any separately engaged tax filing before comparing totals. See the provider pricing research table.
DIY Cost Seg reviews: evaluate the evidence
This page is Stratum’s commercial analysis of service scope, not a customer rating or a review of a report we commissioned. We have not independently audited DIY Cost Seg client outcomes.
For this research question — Does my unit count require the commercial report route? — look for feedback that describes the actual deliverable, the property involved and the reviewer or support process.
Identify who published a review, whether the reviewer bought the same product you are considering and when the experience occurred. Provider-selected testimonials and open review-platform feedback can answer different questions. Neither a high rating nor a single complaint establishes the technical quality of your eventual study.
Start with the official provider source and independently verify any linked review profile. Read our cost segregation review evaluation guide before relying on a ranking.

Questions before choosing DIY Cost Seg or Stratum
What should I ask DIY Cost Seg before comparing proposals?
Does my unit count require the commercial report route? Verify product eligibility before paying and agree how input errors will be corrected.
Does a Stratum study require changing my CPA?
You can keep your existing preparer when commissioning a Stratum study. Identify who reviews the report, updates depreciation schedules and handles any separately engaged filing work. Ask DIY Cost Seg to specify those responsibilities in its own proposal.
What would Stratum charge for my property?
The fee is the greater of $2,000 or property square footage × $1. A 1,500-square-foot property costs $2,000; a 3,500-square-foot property costs $3,500. Calculate the fee and review scope. A study fee is separate from any separately engaged planning or return preparation.
