Seneca Cost Segregation Review: Scope & Stratum Alternative
Seneca is a meaningful cost segregation competitor for rental buyers. Its public process describes property review, a virtual site visit and a report for the CPA. Compare those commitments with a written Stratum study proposal and the separate AE planning assignment.
Our recommendation and relationship
Published by BNB Accelerator. These are commercial editorial reviews of public service information, not independent ratings, firsthand testing or customer testimonials. BNB refers clients to AE Tax Advisors; that relationship may influence our recommendations. Stratum coordinates its discovery and tax-strategy discussion through AE. You may use your own CPA or study provider.
What the provider publishes
Seneca describes engineering-based studies, virtual property visits, a PDF report and fixed asset schedule. Its advertised AuditDefense refund depends on conditions, including a greater-than-5% depreciation adjustment caused by Seneca. It is not an unconditional promise covering every tax dispute.

Read the support terms before comparing guarantees
Ask for the actual AuditDefense language and identify response duties, exclusions, time limits and what the refund covers. A study-fee refund is different from paying additional tax, penalties or representation costs. Apply the same questions to Stratum. No guarantee label establishes that a report cannot be questioned.
Separate the preliminary estimate from the final study
Seneca markets an initial benefit estimate and then gathers property information for the study. Ask which costs are verified, how a virtual visit records relevant components and how missing records affect the final report. For BNB acquisitions, preserve evidence during furnishing and improvements so the study does not depend solely on a rough purchase-price assumption.
Why we recommend comparing Stratum
Stratum’s published residential pricing and discovery connection with AE give BNB buyers a straightforward place to request a study scope. The planning handoff is the reason to compare it, not a claim that Seneca lacks CPA coordination. Ask each provider to describe the exact schedules and correction support the filing professional receives.
A practical proposal test
Send the same closing statement, furnishing schedule, improvement history and prior depreciation to both providers. Ask each to identify land treatment, excluded assets and delivery dependencies. Compare the study price plus separately billed filing and planning. If the projected immediate benefit is uncertain, have the filing professional assess that uncertainty before authorizing either report.
Compare the work in writing
Before commissioning a report, ask your filing professional what evidence, basis reconciliation and schedules are needed. Identify study work, owner-level analysis and return preparation as separate responsibilities. Compare proposals using the same property facts and keep preliminary estimates marked as estimates.
