The decision this comparison helps you make
These providers publish more than one study path. Compare the review and inspection level appropriate to the property before comparing the cheapest product on each site.
This is an editorial comparison of proposal fit. It does not rank either provider or claim Stratum has tested their final reports.
| Decision | RE Cost Seg | CostSegEZ |
|---|---|---|
| Published model | Rapid uses an owner questionnaire; Fully Engineered adds virtual or in-person inspection. | DIY, Engineer Reviewed and Fully Engineered tiers; eligibility and support differ. |
| Scope question | Which records are needed beyond square footage and purchase price? | How are unusual property features and renovations reviewed? |
| Published fee research | Rapid from $950; engineered from $2,320 residential / $2,730 commercial. Official source (2026-10-19) | DIY $595; reviewed $895; fully engineered from $2,500. Official source (2026-10-13) |

A property scenario to compare
Illustrative buyer situation, not a client case study: A rental purchase includes substantial renovations and incomplete invoices. You need a written decision on whether the standard product fits, what additional evidence must be gathered and which professional reviews reconstructed costs.
Three answers to obtain in writing
- Do renovation amounts change the eligible tier?
- What physical inspection is included in this proposal?
- Does support include written technical answers, and what is excluded?
Record each answer beside the relevant proposal clause. If a provider needs new information before answering, identify the missing record and the person responsible. Do not treat an unanswered question as a negative fact about the firm.
How to normalize the two proposals
Use the same closing records, cost history and intended filing year. Identify included buildings, later work, furnishings and any excluded assets. Keep the preliminary benefit estimate separate from the fee and from the deductions your preparer expects you can use.
A shorter delivery target can be valuable near a filing deadline, but only after the scope and intake dependencies are clear. Ask when the delivery clock starts, what happens if records change, and who answers the CPA after delivery.
