A comparison of 6 providers — what each does best, at what price, with what turnaround.
Different providers fit different buyer profiles. Here's the short version:
| Provider | Price range | Turnaround | Site visit | Audit support |
|---|---|---|---|---|
| Cost Seg Smart (this site's operator) | $495–$2,995 | Under 1 hour | Remote (photos + assessor data + plan documents) | Written audit defense included with every study |
| KBKG | $3,000–$25,000+ | 4–8 weeks | On-site required for most engagements | Add-on retainer |
| CSSI (Cost Segregation Services, Inc.) | $5,000–$30,000 | 6–10 weeks | On-site | Included; expert testimony available |
| Engineered Tax Services (ETS) | $5,000–$50,000 | 6–12 weeks | On-site | Included |
| Capstan Tax | $4,000–$20,000 | 4–8 weeks | On-site | Included |
| Local CPA + engineering review | Varies — typically $2,500–$10,000 | Varies | Depends | Depends — verify in engagement letter |
Gatlinburg's portfolio-owner concentration means many investors are buying their 4th, 5th, or 12th cabin — repeat customers who care about repeatable per-property pricing and fast turnaround. The remote-first model produces the same engine output as on-site engagements at one-fifth the price and one-tenth the turnaround time. For portfolio operators evaluating 3+ cabins per year, the speed differential matters more than the absolute dollar saved per study.
Three questions to answer before contacting any provider:
Price ranges are based on publicly stated tiers and industry sources as of 2026. Turnaround times reflect typical engagement lengths and may vary. We do not receive compensation from any other provider listed; this is not affiliate content.
The "best for" framing reflects each provider's actual public sweet spot — not paid placement. We don't claim to be #1 for every customer profile. We're the best fit for the segment described in our row (fast, affordable, remote-first, residential + STR + small commercial under $5M). For larger commercial portfolios, engineer-led firms with on-site capacity are the right choice.
