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 |
| 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 |
Asheville's first-time-STR-buyer concentration means many study customers are new to the cost-seg conversation entirely. Clear before-and-after federal-plus-NC math and explicit NC addback treatment in the study output matters more here than for portfolio-investor markets like Gatlinburg or Denver.
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 (office, retail, industrial, multifamily 5+), engineer-led firms with on-site capacity are the right choice, see commercialcostseg.com for our institutional commercial coverage and provider patterns.
